Google has issued an update for the Chrome browser to patch 32 security issues . One of the vulnerabilities is rated as critical, so install that update as soon as you can.
The post Update now! Multiple vulnerabilities patched in Google Chrome appeared first on Malwarebytes Labs.

Google has announced an update for the Chrome browser that includes 32 security fixes. The severity rating for one of the patched vulnerabilities is **Critical**.

The stable channel was promoted to 102.0.5005.61/62/63 for Windows, and 102.0.5005.61 for Mac and Linux.

**Critical**

Google rates vulnerabilities as critical if they allow an attacker to run arbitrary code on the underlying platform with the user’s privileges in the normal course of browsing.

Publicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database. Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services).

This update patches the critical vulnerability listed as CVE-2022-1853: Use after free in Indexed DB.

Use after free (UAF) is a vulnerability due to incorrect use of dynamic memory during a program’s operation. If after freeing a memory location a program does not clear the pointer to that memory, an attacker can use the error to manipulate the program.

IndexedDB is a low-level Application Programming Interface (API) for client-side storage of significant amounts of structured data, including files. This API uses indexes to enable high performance searches of this data. While Document Object Model (DOM) Storage is useful for storing smaller amounts of data, IndexedDB provides a solution for storing larger amounts of structured data.

Each IndexedDB database is unique to an origin (typically, this is the site domain or subdomain), meaning it should not be accessible by any other origin.

Google does not disclose details about vulnerabilities until users have had ample opportunity to install the patches, so I could be reading this wrong. But my guess is that an attacker could construct a specially crafted website and take over the visitor’s browser by manipulating the IndexedDB.

**Other vulnerabilities**

Of the remaining 31 vulnerabilities, Google has rated 12 as **High**. High severity vulnerabilities allow an attacker to execute code in the context of, or otherwise impersonate, other origins.

Another 13 vulnerabilities were rated as **Medium**. Medium severity bugs allow attackers to read or modify limited amounts of information, or which are not harmful on their own but potentially harmful when combined with other bugs.

Which leaves six vulnerabilities that were rated as **Low**. Low severity vulnerabilities are usually bugs that would normally be a higher severity, but which have extreme mitigating factors or a highly limited scope.

**How to update**

If you’re a Chrome user on Windows, Mac, or Linux, you should update to version 101.0.4951.41 as soon as possible.

The easiest way to update Chrome is to allow it to update automatically, which uses the same method as outlined below but doesn’t need you to do anything. But you can end up blocking automatic updates if you never close the browser, or if something goes wrong, such as an extension stopping you from updating the browser.

So, it doesn’t hurt to check now and then. And now would be a good time, given the severity of the vulnerabilities listed.

My preferred method is to have Chrome open the page **chrome://settings/help** which you can also find by clicking **Settings > About Chrome**.

If there is an update available, Chrome will notify you and start downloading it. Then all you have to do is relaunch the browser in order for the update to complete.

You should then see the message, “Chrome is up to date”.

Affected systems:

*   Google Chrome for Windows versions prior to 102.0.5005.61/62/63
*   Google Chrome for Mac and Linux versions prior to 102.0.5005.61

Stay safe, everyone!

Update now! Multiple vulnerabilities patched in Google Chrome

We take a look at services claiming to offer verification of Instagram accounts, along with the many ways it can go wrong.
The post Instagram verification services: What are the dangers? appeared first on Malwarebytes Labs.

Instagram, like other social platforms, has a verification system for high profile accounts. A verified badge means **I**nstagram has confirmed that the account is the authentic presence of a public figure, celebrity or brand.

Have you ever wanted to get your own account verified? We noticed a large number of Instagram accounts all claiming to offer this as a service. Quick, easy, guaranteed. Or so they claim. After digging into it, we had a few questions of our own.

**Setting the scene**

Here’s just some of the identical profiles we’ve seen promoting one specific verification service.

Most of the profiles contain the same information in the bio section. Here’s a typical example:

The verification process “takes 1-2 hrs”, has a 100% success rate, and payment is required before processing. You can send a direct message, or visit their shortened link for more information.

**Forming an orderly line**

The link in the bio section leads to a Google Docs form. Unless you view the document while signed into a Google account, you won’t be able to see the content or fill it in.

The service says it will submit your profile to Instagram for verification. Given the only way to do this as a regular user is submit it yourself via the app, this means the service would presumably need your login details to do it. This is highly relevant to our next line of investigation.

**Of media partners and promotional agencies**

One section of the form notes the slick, professional approach it has in relation to verification and third-parties:

*   We would like to share everything about our service and marketing strategy. We are the only legitimate agency that provides a guarantee of verification. If we are not able to get you the blue badge, we will refund your entire payment.
*   As you know we have a few talented Instagram media partners agencies. They will do everything for your verification with maintaining all the terms of Instagram authority. They are highly qualified to do that and have a high success rate.

As this article mentions, celebrities may work with agencies with access to Facebook’s Media Partner Support for verification instead. Incidentally, that’s another approach filled with booby-traps. Do we think any of these identical profiles are working to that level?

The form also lists several Instagram accounts which have been “successfully verified” as a result of its guidance. This includes one account which no longer exists, and a well known brand of cheese spread which doesn’t appear to post content anymore. We reached out to the two Instagram accounts which accept direct messages, but didn’t receive a reply.

With all of this in mind, it’s time to ask one of these accounts some questions directly.

**Question time for an Instagram verification service**

I sent a message to the profile highlighted up above.

I asked the following:

_Hi, I have some questions about the verification process and was hoping you could answer before I sign up._

> _1) What are the fees, and which payment method do you use_
> 
> _2) The form says you use a “few talented Instagram media partner agencies”. Who are the agencies?_
> 
> _3) If there’s a 100% success rate, why is there a money back guarantee for unsuccessful applications?_
> 
> _4) How did you help to verify several accounts which are much older than your own?_
> 
> _5) Why is your own account not verified?_
> 
> _Thanks!_

Question 5 is particularly important: with so many identical profiles, _how do we even know which one is the real deal_? If verification is so easy, _where is their own verified profile badge_?

At any rate, they only replied after a follow-up message, promised to answer my questions immediately, and promptly disappeared again. It seems my verified status is not to be, but on the evidence seen so far, I think I can live without paying someone money for the privilege.

**How verify me scams on social media usually end**

There’s a few likely final destinations for respondents of detail-free, evasive operations nestled inside dozens of spam accounts.

1.  They (eventually) send you a request for payment and a link to their processing tool of choice. Once you pay, you never see them or the money again. If you had as much difficulty as I did trying to get basic information from a supposed Instagram verifier, would you trust them with your money?
2.  You’re sent a link to a website asking you to fill in your details. The website is nothing more than a phishing page, grabbing personal details and login information. Worth noting that although the “service” I encountered above made use of a Google Docs form, it did _not_ ask for logins.

> @instagram our business page gets many scam imposter accts a week pretending to be us & asks our customers for money. We have tried 4 times to get verified without success. We tried again & got this. I assume this isn’t real but at this point I’m almost desperate enough. Fake? pic.twitter.com/8LuamvPnHI
> 
> — Sharpie (@itsmesharpie) March 24, 2021

3.  Either of these methods may involve a request for scans of identification. Sending scammers copies of your passport pages is never going to be a good idea. One of the most brazen combinations of most of these tactics can be seen in this CNET article from last year.

**Safe verification practices**

There’s a bit of mystery as to how certain sites verify individuals. Instagram is refreshingly straightforward and direct in its approach. It pretty much all boils down to preventing impersonation of “notable” individuals. If you’re in a big pile of press links, articles about you, things which have gained column inches somewhere, then you’re probably going to be verified.

Here’s some more information from the Head of Instagram, Adam Mosseri:

Follower count doesn’t matter. If you see someone claiming to offer verification based on follower count, you can safely disregard that entity. If you’re asked to login somewhere then don’t do it. And don’t send scans of identification documentation either.

The allure of verification on social media is too powerful for many people to resist, and that’s what scammers are banking on. If you believe you need it, by all means send in an application to your platform of choice. By the same token, think very carefully about entrusting non-verified spam accounts with your personal details, money, or even identity documents. It almost certainly won’t turn out to have been worth it.

Instagram verification services: What are the dangers?

US car producer General Motors says its Rewards platform was the victim of a credential stuffing attack last month.
The post General Motors suffers credential stuffing attack appeared first on Malwarebytes Labs.

American car manufacturer General Motors (GM) says it experienced a credential stuffing attack last month. During the attack customer information and reward points were stolen.

The subject of the attack was an online platform, run by GM, to help owners of Chevrolet, Buick, GMC, and Cadillac vehicles to manage their bills, services, and redeem rewards points.

**Credential stuffing**

Credential stuffing is a special type of brute force attack where the attacker uses existing username and password combinations, usually ones that were stolen in a data breach on another service.

The intention of such an attack is not to take over the website or platform, but merely to get as many valid user account credentials and use that access to commit fraud, or sell the valid credentials to other criminals.

To stop a target from just blocking their IP address, an attacker will typically use rotating proxies. A rotating proxy is a proxy server that assigns a new IP address from the proxy pool for every connection.

**The attack**

GM disclosed that it detected the malicious login activity between April 11 and April 29, 2022, and confirmed that the threat actors exchanged customer reward bonuses of some customers for gift certificates.

The My GM Rewards program allows members to earn and redeem points toward buying or leasing a new GM vehicle, as well as for parts, accessories, paid Certified Service, and select OnStar and Connected Services plans.

GM says it immediately investigated the issue and notified affected customers of the issues.

**Victims**

GM contacted victims of the breach, advising them to follow instructions to recover their GM account. GM is also forcing affected users to reset their passwords before logging in to their accounts again. In the notification for affected customers, GM said it will be restoring rewards points for all customers affected by this breach.

GM specifically pointed out that the credentials used in the attack did not come from GM itself.

> “Based on the investigation to date, there is no evidence that the log in information was obtained from GM itself. We believe that unauthorized parties gained access to customer login credentials that were previously compromised on other non-GM sites and then reused those credentials on the customer’s GM account.”

**Stolen information**

Attackers could have accessed the following Personally Identifiable Information (PII) of a compromised user:

*   First and last name
*   Email address
*   Physical address
*   Username and phone number for registered family members tied to the account
*   Last known and saved favorite location information
*   Search and destination information

Other information that was available was car mileage history, service history, emergency contacts, Wi-Fi hotspot settings (including passwords), and currently subscribed OnStar package (if applicable).

GM is offering credit monitoring for a year.

**Mitigation**

What could GM have done to prevent the attack? It doesn’t currently offer multi-factor authentication (MFA)which would have stopped the attackers from gaining access to the accounts. GM does ask customers to add a PIN for all purchases.

This incident demonstrates how dangerous it is to re-use your passwords for sites, services and platforms. Even if the account doesn’t seem that important to you, the information obtainable by accessing the account could very well be something you wish to keep private.

Always use a different password for every service you use, and consider using a password manager to store them all. You can read some more of our tips on passwords in our blog dedicated to World Password Day.

Stay safe, everyone!

General Motors suffers credential stuffing attack

A spyware vendor called Cytrox was found to be using several zero-day vulnerabilities in Google's Chrome browser and the Android kernel component. 
The post Zero-day vulnerabilities in Chrome and Android exploited by commercial spyware appeared first on Malwarebytes Labs.

The Google Threat Analysis Group (TAG) has revealed that of the nine zero-day vulnerabilities affecting Chrome, Android, Apple and Microsoft that it reported in 2021, five were in use by a single commercial surveillance company.

Did I hear someone say Pegasus? An educated guess, but wrong in this case. The name of the surveillance company—or better said, professional spyware vendor—is Cytrox and the name of its spyware is Predator.

**Google**

TAG routinely hunts for zero-day vulnerabilities exploited in-the-wild to fix the vulnerabilities in Google’s own products. If the group finds zero-days outside of its own products, it reports them to the vendors that own the vulnerable software.

Patches for the five vulnerabilities TAG mentions in its blog are available. Four of them affected the Chrome browser and one the Android kernel component.

**Vulnerabilities**

By definition, zero-day vulnerabilities are vulnerabilities for which no patch exists, and therefore potentially have a high rate of success for an attacker. That doesn’t mean that patched vulnerabilities are useless to attackers, but they will have a smaller number of potential targets. Depending on the product and how easy it is to apply patches, vulnerabilities can be useful for quite a while.

In the campaign uncovered by TAG, the spyware vendor used the zero-days in conjunction with other already-patched vulnerabilities. The developers took advantage of the time difference between the availability of patches for some of the critical bugs, as it can take a while before these patches are fully deployed across the Android ecosystem.

TAG says Cytrox abused four Chrome zero-days (CVE-2021-37973, CVE-2021-37976, CVE-2021-38000, and CVE-2021-38003) and a single Android zero-day (CVE-2021-1048) last year in at least three campaigns conducted on behalf of various governments.

**Cytrox**

TAG is actively tracking more than 30 vendors with varying levels of sophistication and public exposure selling exploits or surveillance capabilities to government-backed actors. Cytrox is one of these vendors, along with the NSO Group—undoubtedly the best known one among them and responsible for Pegasus spyware.

Citizenlab at the University of Toronto published information about Cytrox in December 2021. It says that Cytrox describes its own activities as providing governments with an “operational cyber solution” that includes gathering information from devices and cloud services. It also says it assists with “designing, managing, and implementing cyber intelligence gathering in the network, enabling businesses to gather intelligence from both end devices as well as from cloud services.”

Cytrox reportedly began life as a North Macedonian start-up and appears to have a corporate presence in Israel and Hungary. As such, Cytrox is believed to be part of the so-called Intellexa alliance, a marketing label for a range of mercenary surveillance vendors that emerged in 2019. The consortium of companies includes Nexa Technologies (formerly Amesys), WiSpear/Passitora Ltd., Cytrox, and Senpai, along with other unnamed entities, purportedly seeking to compete against other players in the cyber surveillance market such as NSO Group (Pegasus) and Verint.

**Government spyware**

Spyware packages such as Predator and Pegasus create problematic circumstances for the security teams at Google, Apple, and Microsoft, and it seems like they will not stop any time soon.

Whatever arguments these vendors use about how they are working for governments, and therefore not doing anything illegal, we all know the legitimacy of some governments lies in the eye of the beholder. And it is not always easy to find out who actually controls the data received from the spyware.

It is for good reason that the European Data Protection Supervisor (EDPS) has urged the EU to ban the development and deployment of spyware with the capabilities of Pegasus to protect fundamental rights and freedoms. The EDPS argues that the use of Pegasus might lead to an unprecedented level of intrusiveness, threatening the very essence of the right to privacy, since the spyware is capable of interfering with the most intimate aspects of our daily lives.

An in-depth look at the attack chain used by an unknown APT group that has launched four campaigns against Russian targets since February.
The post Unknown APT group has targeted Russia repeatedly since Ukraine invasion appeared first on Malwarebytes Labs.

An unknown Advanced Persistent Threat (APT) group has targeted Russian government entities with at least four separate spear phishing campaigns since late February, 2022.

The campaigns, discovered by the Malwarebytes Threat Intelligence team, are designed to implant a Remote Access Trojan (RAT) that can be used to surveil the computers it infects, and run commands on them remotely. The malware uses a number of advanced tricks to hide what it does and how it works, but our analysts have been able to reverse engineer the malware, reveal its inner workings, and uncover some clues about its possible origins.

Attribution is always difficult, and there is no shortage of countries or agencies with an interest in getting covert access to Russian government computers—and the recent invasion of Ukraine has simply increased the stakes. Although our analysis and attribution efforts are ongoing, we have discovered some indicators that suggest the threat actor may be a Chinese group.

**The campaigns**

The APT group has launched at least four campaigns since late February, using a variety of lures, detailed below.

**1\. Interactive map of Ukraine**

The threat actor started this campaign around February 26, 2022, and distributed its custom malware with the name interactive_map_UA.exe, trying to disguise it as an interactive map of Ukraine. This campaign began a few days after Russia invaded Ukraine, which shows the threat actor was monitoring the situation between Ukraine and Russia and took advantage of it to lure targets in Russia.

**2\. Log4j patch**

In this campaign the threat actor packaged its custom malware in a tar file called Patch_Log4j.tar.gz, a fake fix for December’s high-profile Log4j vulnerability.

This campaign ran in early March and was primarily aimed at RT TV (formerly Russia Today or Rossiya Segodnya, a Russian state-controlled international television network funded by the Russian government). The APT group had access to almost 100 RT TV employees’ email address.

The emails were sent with the subject “Ростех. ФСБ РФ. Роскомнадзор. Срочные сиправления уязвимостей”, which translates into “Rostec. FSB RF. Roskomnadzor. Urgent Vulnerability Fixes”. (Rostec is a Russian state-owned defense conglomerate founded by Putin.)

The emails also come with a number of image files and a PDF attached, perhaps to make the email less suspicious, and to bypass any systems that flag emails by number of attachments.

A spear phishing email from an unknown APT group claims to have “urgent vulnerability fixes”

The PDF attachment—О кибербезопасности 3.1.2022.pdf—pretends to be from the “Ministry of Digital Development, Telecommunications and Mass Communications of the Russian Federation”. It contains instructions about how to execute the fake patch, as well as a bulleted list of security advice such as “Use two-factor authentication”, “Issue separate credit cards for purchases”, and “Use Kaspersky antivirus”.

A PDF attachment tries to build trust with security advice and instructions on how to run the fake Log4j patch

In a confident demonstration of just how little attention people pay to such lists it ends “Do not open or reply to suspicious emails.”

The list even includes a link to a page on VirusTotal that proclaims in bright green letters that “No security vendors and no sandboxes flagged this file as malicious”. This is just another effort to convince the victims that the attachment is not malicious—the file on VirusTotal has nothing to do with the attachment and appears to be a legitimate OpenVPN file.

The PDF attachment links to a VirusTotal entry for an unrelated file

In another effort to build trust, the spear phishing email links to the website rostec.digital, a domain registered by the threat actor, hosting a site made look like the official Rostec website.

This email also contains links to fake Instagram and Facebook accounts. Interestingly, the threat actor created the Facebook page in June 2021, nine months before it was used in this campaign. This was probably an attempt to attract followers, to make the page look more legitimate, and it suggests the APT group were planning this campaign long before the invasion of Ukraine.

**3\. Build Rostec**

The Rostec defense conglomerate also appears in the third campaign. This time the threat actor used the file name build_rosteh4.exe for its malware—an apparent attempt to make it look like software from Rostec.

**4\. Saudi Aramco job**

The most recent campaign occured in mid April and used a Word document containing a fake job advert for a “Strategy and Growth Analyst” position at Saudi Aramco as a lure.

(We also discovered a self-extracting archive file that belonged to this campaign—the archive file used a Jitsi video conferencing software icon as decoy, and created a directory named Aramco under C:\ProgramData.)

Although the job advert is written in English, it also contains a message in Russian, asking users to enable macros.

A malicious job advert urges Russian readers to enable macros

The document uses remote template injection to download a macro-embedded template, which executes a macro that drops a VBS script called HelpCenterUpdater.vbs in the %USER%\Documents\AdobeHelpCenter directory.

The template also seems to do a redundant check for the existence of %USER%\Documents\D5yrqBxW.txt and only if it doesn’t exist, will it drop the script and execute it.

Macros embedded in the remote template

The obfuscated HelpCenterUpdater.vbs script drops another obfuscated VBS file named UpdateRunner.vbs and downloads the main payload—a DLL named GE40BRmRLP.dll—from its command and control (C2) server. (Interestingly, some anti-analysis code, and code responsible for persistence, seems to be commented out in UpdateRunner.vbs and isn’t executed.)

In another payload related to this campaign, the script seems to drop an EXE instead of a DLL, but after analyzing both it seems they share the same code.

Deobfuscated HelpCenterUpdater.vbs

The job of the UpdateRunner.vbs script is to execute the DLL through rundll32.exe.

Deobfuscated UpdateRunner.vbs

The malicious DLL contains the code that communicates with the C2 server and executes the commands it receives from it.

The attack chain for the Saudi Aramco-themed APT campaign

The malware, which is common to all four campaigns, is explained in detail in the next section.

**Payload analysis**

This analysis focuses on the GE40BRmRLP.dll payload from the Saudi Aramco campaign, but the malware used in all four campaigns is essentially the same, with small differences in the code.

The DLL is heavily obfuscated and most of the library functions are statically linked. IDA is barely able to recognize any functions, though it was able to recognize a few that indicate the DLL was most likely compiled with LLVM. The DLL’s original name is supposed to be simpleloader.dll, as we can see after analyzing it a bit.

The DLLMain function from GE40BRmRLP.dll

Before we dive into the functionality and capabilities of this malware, let’s look at various methods it uses to make the analysis difficult for us.

**Anti-analysis techniques****Control Flow Flattening**

All of the samples used in these campaigns use control flow flattening heavily, a technique that flattens the nested structure of a program, making analysis very difficult. We used the D810 plugin for IDA which has the capability to deobfuscate flattened code and make the decompilation more readable.

Although there are many tools that can perform control flow flattening, in this case we suspect OLLVM—an obfuscator for LLVM—was used. The different samples had different levels of flattening and OLLVM allows users to specify this. Additionally we also saw what looks like the Bogus Control Flow LLVM pass being used.

Control Flow Flattening used by the malware

**String obfuscation**

The payload’s strings are obfuscated with simple XOR encoding. The decode_string function which is used to decode a string takes 3 arguments: The encoded string, the destination of the decoded string, and the byte that is used while decoding the string.

Each string is decoded every time it’s required by the malware.

The decode_string function from GE40BRmRLP.dll

**Command and control**

Before contacting its C2 server the malware derives an ID which is unique to every machine, which could be used to differentiate infections. It uses the data from the following APIs to construct the ID:

*   GetFileAttributesA on the C:\Windows directory
*   GetComputerNameA
*   GetVolumeInformationA on the C:\ drive

It then calculates a hash of this data using the Blake2b-256 algorithm and sends it when it makes the first contact with its C2.

Deriving the ID

The C2 address is decoded every time the malware sends a request. To communicate with the C2 the malware uses GET requests in the form url/?wSR=_data_, where _data_ contains the encoded information.

Interestingly Any.run and Fiddler fail to capture the HTTPS requests made by the malware. To make them, the malware doesn’t use any library functions but instead implements everything over raw sockets, and it uses the WolfSSL library to implement SSL itself. Our analysis also uncovered traces of http-parser from ZephyrOS. The certificate used for the SSL communication is stored inside the binary as chunks of encoded strings. Initially the malware decodes this data and stores it. Later, while making the HTTPS request, it loads this data using WolfSSL’s loadX509orX509REQFromBuffer.

After making every request the malware sleeps for a random amount of time.

HTTPS GET request

Based on the response to the above request, the malware decides which of command to execute:

1.  **getcomputername**. This retrieves the computer name using GetComputerNameA and sends a response to the C2 containing the unique id and the computer name.
2.  **upload**. This receives a file name and file contents from the C2 which it writes to the local file system.
3.  **execute**. This receives a command line instruction from the C2 and executes it using CreateProcessA. If the command is successful then the malware sends the UID with the “OK” string to the C2, or the output of GetLastError if it fails.
4.  **exit**. This is used to terminate the malware process.
5.  **ls**. This command uses a directory name from the C2, or the name of the current directory if one isn’t provided. It uses the FindFirstFile and FindNextFile function to retrieve a list of all the files under the directory and sends it back to the C2.

The upload command

The List Files command

**Attribution**

Attribution is difficult, and threat actors are known to use indicators from other groups as false flags. The attribution of the APT behind these campaigns is ongoing, but based on the infrastructure used we assess with low confidence that this group is a Chinese actor.

All of the C2s are from BL Networks, which has been used by Chinese APTs in the past. Also, we discovered infrastructure overlap between the malware we analyzed and the Sakula Rat malware used by the Deep Panda APT.

Infrastructure overlap between Sakula RAT and the malware analzed in this article

Another interesting indicator we found was that the macro used in the Aramco campaign is almost identical to some macros used by TrickBot and BazarLoader in the past. We think the actor may have used the same macro builder to generate its macro, and they may have used it as a false flag. There are some other weak indicators, such as WolfSSL, which has been used by Lazarus and Tropic Troopers, but they are not enough to help attribute the attack to any specific actor.

Malwarebytes customers were proactively protected against these campaigns thanks to our heuristic detection engines.

This week on Lock and Code, we speak with Whitney Merrill about why it is so difficult to get your own data from a company. 
The post Hunting down your data with Whitney Merrill: Lock and Code S03E11 appeared first on Malwarebytes Labs.

Depending on where you live, you can ask a company to hand over all the data it has collected about you and, in a matter of weeks as mandated by law, that company has to fork that information over.

Whether the company will abide on time, however, is a different story.

In the European Union, the United Kingdom, and California, consumers have a leg up in understanding what data is collected about them, largely thanks to several laws passed in those regions in the last few years. And at least in California, people can request that a company hand over the data it has collected about them, even if they are not an active user of that company’s product or a customer of that company’s services.

That’s because in today’s world, your data is not collected only by the companies you directly interact with, but also by the companies that your friends and families interact with.

In February of last year, Whitney Merrill proved this was true when she requested her data from the then-popular app Clubhouse. Though Merrill did not have an account with the company and was not a user of the app, she proved that Clubhouse did have her phone number, which had been shared with Clubhouse by Merrill’s contacts who were active users.

Merrill, who has requested her data from several more companies since then, learned more about data privacy compliance than about just what is being collected about her. Each request, Merrill said, can be different from another, and each request is done separately, forcing users who want to learn more about how their data is collected to spend increasingly more of their own time—time which they may not realistically have. The entire model right now, Merrill said, has many flaws.

> “We all interact with thousands and thousands of websites and providers that collect our data—maybe hundreds is probably a better number—in any given week or year. And, as a result, you have to go to each individual one and ask for access to your data… The burden is really on the end user.”

This week on the Lock and Code podcast with host David Ruiz, we speak with Merrill about the difficulties of requesting your own data from a company and why some companies seem to interpret data privacy laws as mere suggestions. We also touch on proposed solutions to today’s problems with cross-border data transfers and what “data localization” may lead to in the future.

Hunting down your data with Whitney Merrill: Lock and Code S03E11

A recent breach notification has revealed some 490,000+ students were impacted by a ransomware attack last December.
The post Chicago students lose data to ransomware attackers appeared first on Malwarebytes Labs.

Chicago Public Schools (CPS) disclosed on Friday that students may have had their data taken in a ransomware incident involving one of its vendors.

The ransomware attack happened last December at Battelle for Kids (BfK), based in Columbus Ohio, which develops services to provide innovation in schools for students and teachers.

**Breaching education**

Around 490,000 students and 56,000 employees found their data breached by those responsible for the ransomware. The data accessed by criminals, stretching from 2015 to 2019, included a variety of information potentially including:

*   Name
*   School
*   CPS email
*   Employee ID number
*   Battelle for Kids username

The notification breach says that home addresses, health/financial information, and social security numbers were not exposed.

Chicago Public Schools is offering free credit monitoring for those affected.

**A late notification**

The breach occurred in December but the notification did not, which raises several questions related to lateness of notification for those impacted. According to Bleeping Computer, the CPS contract with BfK means immediate notification of any data breach.

Despite this, it took no fewer than _four months_ to get word out that something had occurred. Letters pertaining to the breach were sent out towards the end of April. The reason for this is that it took this long to verify the breach had actually taken place. That isn’t all, however. Other breaches related to the compromise of Battelle for Kids suggests private student data was revealed “as far back as 2011”.

According to the Chicago Sun Times, a spokesperson for CPS says the breach was “caused \[and\] exacerbated by BfK’s failure to follow the information security terms of their contract”. They go on to single out a failure to encrypt data and purge old records. We talk about ransomware breaches often, and frequently mention the benefits of having a sensible back-up plan. This sounds like a case which may well have benefited greatly from this approach.

**Schools: a ripe target for ransomware**

All forms of education are an increasingly popular place to be for ransomware criminals. Schools, Universities, and (as we see above) third-party organisations are all valid targets. Even if the schools have a watertight security setup, it may not be the case for external suppliers and other entities interacting with the data in some way.

Outbreaks in schools and universities may not be life-threatening in the way attacks on the healthcare sector can be. However, severe delays to applications, operations, and teaching generally can have a big impact on students.

**Tips to avoid ransomware**

*   **Keep devices updated**. Secure your devices with the latest updates and patches. It’s not just the Operating System you have to consider here. Outdated software and applications are frequently the launchpad for exploits leading to ransomware attacks.
*   **Update your security software**. Often your first line of defence, help it to help you by automating updates and scans.
*   **Strengthen remote access**. A common ransomware pitfall is leaving remote services unsecured. Provide a limit on password guess attempts for remote desktops. You can also combine remote services with multifactor authentication.
*   **Avoid strange attachments**. Booby-trapped Word/Excel documents are a big threat in these realms, especially where Macros are concerned.
*   **Browser controls for bad ads**. Malvertising is another method for dropping ransomware onto systems. Restricting certain features like JavaScript will help, though this may make some sites unusable in places. Dedicated extensions which control scripts more generally, tracking, or untrustworthy ad networks will also help.
*   **Encrypt and back it up**. Keep your data encrypted whenever possible, and get into the habit of backing up regularly. Store backups externally, away from the main network. Ensure your backups are stored in a logical way and not a confused mess of folders and files, so you can easily find and restore files if you need to.

NVIDIA recently released patches to address multiple flaws in Windows. Four of them were rated high in severity.
The post Update now! Nvidia released fixes for 10 flaws in Windows GPU drivers appeared first on Malwarebytes Labs.

Multiple NVIDIA graphic card models have been found to have flaws in their GPU drivers, with six medium-and four high-severity ratings.

Last Monday, the company released a software security update for NVIDIA GPU Display Driver to address the vulnerabilities. If exploited, they could lead to denial of service, code execution, privilege escalation, and data tampering.

NVIDIA GeForce software, Studio, RTX/Quadro, NVS, and Tesla running Windows and Linux are all affected by this update, covering driver branches R450, R470, and R510. Here are the lists for Windows and Unix/Linux for reference for driver branch histories.

The latest release also covers updates for already unsupported GTX 600 and GTX Kepler-series cards. This is NVIDIA honoring its promise of continuing to provide support for these cards until September 2024—three years after the October 2021 end-of-support date.

Let’s look at each of the vulnerabilities up-close.

**High-severity NVIDIA vulnerabilities**

*   **CVE-2022-28181.** A malformed executable or shader file (a program that runs on the GPU) exploiting the DCL_INDEXABLE functionality could lead to memory corruption, code execution, data tampering, denial of service, privilege escalation, and information disclosure. Virtual machines and (theoretically) web browsers can trigger this vulnerability. This is exploitable over the network.
*   **CVE-2022-28182**. A malformed executable or shader file exploiting the DCL_INDEXRANGE, DCL_RESOURCE_STRUCTURED, and DCL_UNORDERED_ACCESS_VIEW_STRUCTURED functionalities could lead to memory corruption, data tampering, denial of service, information disclosure, and privilege escalation. Virtual machines and (theoretically) web browsers can trigger this vulnerability. This is exploitable over the network.
*   **CVE-2022-28183**. An unprivileged user could cause an out-of-bounds read (a flaw that allows parts of the memory, which are allocated to more critical functions, to be manipulated), leading to a denial of service and information disclosure. This is exploited with local access.
*   **CVE-2022-28184**. An unprivileged user could access registers available only to administrator accounts, leading to data tampering, denial of service, and information disclosure. This is exploited with local access.

**Medium-severity NVIDIA vulnerabilities**

*   **CVE-2022-28185**. An out-of-bounds write in the ECC (error correction code) layer could lead to data tampering and denial of service.
*   **CVE-2022-28186**. A validation flaw in the kernel mode layer (nvlddmkm.sys) could lead to data tampering and denial of service.
*   **CVE-2022-28187**. A memory management software flaw in the kernel mode layer (nvlddmkm.sys) could lead to denial of service.
*   **CVE-2022-28188**. A validation flaw in kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape where input is not correctly validated for being able to process data safely, which could lead to denial of service.
*   **CVE-2022-28189**. A NULL pointer dereference in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape could lead to a system crash.
*   **CVE-2022-28190**. A validation flaw in kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape where improper input validation could lead to denial of service.

**Patch as soon as possible**

NVIDIA users are advised to download and apply the patches ASAP. The updates can also be applied via NVIDIA’s GeForce Experience suite.

A week in security (May 16 – 22)

We take a look at reports that CEOs and other executives are using weak passwords in their daily dealings. How do we fix this?
The post Why you should act like your CEO’s password is “querty” appeared first on Malwarebytes Labs.

A poor password at the highest levels of an organisation can cost a company millions in losses.

Recent findings show that half of IT leaders store passwords in shared documents. On top of that, it seems that folks at executive level are not picking good passwords either. Researchers from NordPass combed through a large list of CEO and business owner breaches. Their findings should renew considerations for additional security measures at executive level.

**The findings**

The five most common passwords among C-level executives, managers, and business owners were “123456”, “password”, “12345”, “123456789”, and our old friend “qwerty”. Terrifyingly, but perhaps not surprisingly, this looks exactly like every other list of the most frequently used passwords, suggesting no extra precautions are in place (or enforced) at the top.

Executives really love to use the names “Tiffany”, “Charlie”, Michael”, and “Jordan” for their passwords. I was curious to know if these are the names of executives’ name their kids. My entirely unscientific trawl for the names of CEO’s children turned up list of CEOs themselves. Henry, William, Jack, James, and David are all very popular names. This doesn’t match up with our list of password names. However, there _is_ one list which claims that the Michaels of this world are most likely to become CEOs. Are CEOs naming their passwords after themselves? I’d like to think not, but then I probably wouldn’t have expected to be writing about “123456” either.

Animals and mythical creatures are popular choices. When not naming passwords after themselves, dragons and monkeys are both incredibly popular and _also_ incredibly easy to guess.

**Breaking and entering**

Common ways corporate breaches and basic passwords spill all over the floor are issues we’ve covered at length. We recently highlighted recommendations from the Cybersecurity and Infrastructure Security Agency which deal with most of the causes of CEO password loss.

A combination of weak and reused passwords, and risky password-sharing habits make up the majority of hits on the “these passwords can lead to nothing good” indicator.

What happens when you combine bad password practices with human error and poor security infrastructure? These weak and obvious passwords just help to bring the whole thing crashing down that little bit faster.

There are some very smart attacks and compromises out there. Clever attackers can exfiltrate data from a network for weeks or months before making a more overt move. You’d expect people hijacking CEO data to be made to really work for it at every level. Sadly this research seems to suggest the opposite is happening in a lot of cases.

If nothing else, I’d love to see the actual response on the part of the criminals. What do they think when pulling down a C-Level executive’s data and discovering their email password is “sandwich”? Are they surprised? Is it business as usual? Do they think it can’t possibly be real, and they’re staring down the wrong end of a prank or law enforcement bust?

**Is the CEO password sky falling? A word of caution…**

There are some caveats here. The research doesn’t go into detail with regard to additional security measures in place. Yes, a CEO may have the worst password you’ve ever seen. That doesn’t mean the business has been popped right open.

Maybe they had two-factor authentication (2FA) set up. The password may be gone, but unless the attacker also has access to the CEO’s authentication app on their phone, it may not be much use. The CEO may use a hardware authentication token plugged into their desktop. Admins may have set up that one machine specifically for use by the CEO, for all CEO-related activity. It may not be usable remotely, and could be tied to a VPN an added precaution.

Having said all of _that_…

**Manager? Use a password manager**

If we’re talking purely about fixing the short, terrible, obvious passwords, then some additional work is required. 2FA, lockouts, and hardware tokens are great. Ultimately they’re fixing a myriad of _additional_ problems _regardless_ of whether the password is good or bad.

To fix bad password practices, we need to look to tools which can improve them and help keep them a bit more secure at the same time. I am talking about password managers, of course.

A password manager is a software application that gets around the twin evils of poor passwords and password reuse by creating strong, random passwords and then remembering them.

They can function online, so they are accessible via the web and can sync passwords between devices, or they can work entirely offline. Offline password managers are arguably more secure. Online components can add additional risk factors and a way for someone to break in via exploits. The important part is to keep the master password to access your vault secure, and to use 2FA if available for an additional layer of protection. Make your master password long and complex—don’t use “querty”.

Password managers with browser extensions can help deter phishing. Your password manager will object to entering a password into the wrong website, no matter how convincing it looks. No more risk of accidental logins!

Some password manager tools allow you to share logins with other users in a secure fashion. They don’t show or display the password to the other users, rather they just grant a form of access managed by the tool or app itself. If your CEO has no option but to share a password with somebody else, this is the only safe way to do it.

There’s never been a better time to wean ourselves away from shared password documents and the name “Michael” as the digital keys to an organisation’s kingdom. It’s perhaps time for CEOs and other executives to lead from the front where security is concerned.
