After a breach in the Dropbox Sign environment, customer information may have been stolen and API users have restricted functionality

Dropbox is reporting a recent “security incident” in which an attacker gained unauthorized access to the Dropbox Sign (formerly HelloSign) production environment. During this access, the attacker had access to Dropbox Sign customer information.

Dropbox Sign is a platform that allows customers to digitally sign, edit, and track documents. The accessed customer information includes email addresses, usernames, phone numbers, and hashed passwords, in addition to general account settings and certain authentication information such as API keys, OAuth tokens, and multi-factor authentication. The access is limited to Dropbox Sign customers and does not affect users of other Dropbox services because the environments are largely separate.

> “We believe that this incident was isolated to Dropbox Sign infrastructure and did not impact any other Dropbox products.”

Even if you never created a Dropbox Sign account but received or signed a document through Dropbox Sign, your email addresses and names were exposed. In a government (K-8) filing about the incident, Dropbox says it found no evidence of unauthorized access to the contents of customers’ accounts (i.e. their documents or agreements), or their payment information. 

The attacker compromised a back-end service account that acted as an automated system configuration tool for the Dropbox Sign environment. The attacker used the privileges of the service account for the production environment to gain access to the customer database.

To limit the aftermath of the incident, Dropbox’s security team reset users’ passwords, logged users out of any devices they had connected to Dropbox Sign, and is coordinating the rotation of all API keys and OAuth tokens.

For customers with API access to Dropbox Sign, the company said new API keys will need to be generated and warned that certain functionality will be restricted while they deal with the breach.

Dropbox says it has reported this event to data protection regulators and law enforcement.

**Recommendations**

Dropbox expired affected passwords and logged users out of any devices they had connected to Dropbox Sign for further protection. The next time these users log in to their Sign account, they’ll be sent an email to reset the password. Dropbox recommends users do this as soon as possible.

If you’re an API customer, to ensure the security of your account, you’ll need to rotate your API key by generating a new one, configuring it with your application, and deleting your current one. Here is how you can easily create a new key.

API customers should be aware that names and email addresses for those who received or signed a document through Dropbox Sign, even if they never created an account, were exposed. So, this may impact their customers.

Customers who use an authenticator app for multi-factor authentication should reset it. Please delete your existing entry and then reset it. If you use SMS you do not need to take any action.

If you reused your Dropbox Sign password on any other services, we strongly recommend that you change your password on those accounts and use multi-factor authentication when available.

****Protecting yourself from a data breach****

There are some actions you can take if you are, or suspect you may have been, the victim of a data breach.

*   **Check the vendor’s advice.** Every breach is different, so check with the vendor to find out what’s happened and follow any specific advice they offer.
*   **Change your password.** You can make a stolen password useless to thieves by changing it. Choose a strong password that you don’t use for anything else. Better yet, let a password manager choose one for you.
*   **Enable two-factor authentication (2FA).** If you can, use a FIDO2-compliant hardware key, laptop, or phone as your second factor. Some forms of two-factor authentication (2FA) can be phished just as easily as a password. 2FA that relies on a FIDO2 device can’t be phished.
*   **Watch out for fake vendors.** The thieves may contact you posing as the vendor. Check the vendor website to see if they are contacting victims and verify any contacts using a different communication channel.
*   **Take your time.** Phishing attacks often impersonate people or brands you know, and use themes that require urgent attention, such as missed deliveries, account suspensions, and security alerts.
*   **Set up identity monitoring.** Identity monitoring alerts you if your personal information is found being traded illegally online, and helps you recover after.

 Dropbox Sign customer data accessed in breach 

Our researchers found fake sponsored search results that lead consumers to a typical fake Microsoft alert site set up by tech support scammers.

_This blog post was written based on research carried out by Jérôme Segura._

A campaign using sponsored search results is targeting home users and taking them to tech support scams.

Sponsored search results are the ones that are listed at the top of search results and are labelled “Sponsored”. They’re often ads that are taken out by brands who want to get people to click through to their website. In the case of malicious sponsored ads, scammers tend to outbid the brands in order to be listed as the first search result.

The criminals that buy the ads will go as far as displaying the official brand’s website within the ad snippet, making it hard for an unsuspecting visitor to notice a difference.

Who would, for example, be able to spot that the below ad for CNN is not legitimate. You’ll have to click on the three dots (in front of where we added malicious ad) and look at the advertiser information to see that it’s not the legitimate owner of the brand.

Only then it becomes apparent that the real advertiser is not CNN, but instead a company called Yojoy Network Technology Co., Limited.

Below, you can see another fake advertisement by the same advertiser, this time impersonating Amazon.

In our example, the scammers failed to use the correct CNN or Amazon icons, but in other cases (like another recent discovery by Jerome Segura), scammers have even used the correct icon.

The systems of the people that click one of these links are likely to assessed on what the most profitable follow-up is (using a method called fingerprinting). For systems running Windows, we found visitors are redirected to tech support scam websites such as this one.

_Tech Support Scam site telling the visitor to call 1-844-476-5780_

You undoubtedly know the type. Endless pop-ups, soundbites, and prompts telling the visitor that they should urgently call the displayed number to free their system of alleged malware.

These tech support scammers will impersonate legitimate software companies (i.e. Microsoft) and charge their victims hundreds or even thousands of dollars for completely bogus malware removal.

**Getting help if you have been scammed**

Getting scammed is one of the worst feelings to experience. In many ways, you may feel like you have been violated and angry to have let your guard down. Perhaps you are even shocked and scared, and don’t really know what to do now. The following tips will hopefully provide you with some guidance.

**If you’ve already let the scammers in**

*   Revoke any remote access the scammer has (if you are unsure, restart your computer). That should cut the remote session and kick them out of your computer.
*   Scan your computer for malware. The miscreants may have installed password stealers or other Trojans to capture your keystrokes. Use a program such as Malwarebytes to quickly identify and remove threats.
*   Change all your passwords. (Windows password, email, banking, etc.)

**If you’ve already paid**

*   Contact your financial institution/credit card company to reverse the charges and keep an eye out for future unwanted charges.
*   If you gave them personal information such as date of birth, Social Security Number, full address, name, and maiden name, you may want to look at some form of identity theft protection.

****Reporting the scam****

**File a report**

*   In the US: File a complaint (FTC)
*   In Canada: Contact law enforcement
*   In the UK: Report fraud | Report a cold call
*   In Australia: Report a scam

**Shut down their remote software account**

*   Write down the TeamViewer ID (9-digit code) and send it to TeamViewer’s support. They can later use the information you provide to block people/companies.
*   LogMeIn: Report abuse

**Spread the word**

You can raise awareness by letting your friends, family, and other acquaintances know what happened to you. Although sharing your experience of falling victim to these scams may be embarrassing, educating other people will help someone caught in a similar situation and deter further scam attempts.

The hacker behind the extortion of mental health clinic Vastaamo and its clients has been convicted to over 6 years in jail.

On October 30, 2020, I started a article with the words:

“Hell is too nice a place for these people.”

The subject of this outrage focused on the cybercriminals behind an attack on Finnish psychotherapy practice Vastaamo. Because it was a psychotherapy practice, the records contained extremely sensitive and confidential information about some of the most vulnerable people.

Sadly, the attacker did not stop at extorting the clinic but also sent extortion messages to the patients, asking them to pay around $240 to prevent their data from being published online. And that was a first, as far as we know—not just demanding a ransom from the breached organization, but also from all those that were unlucky enough to have their data on record there.

The attacker demanded a €400,000 ($425,000) ransom from the company. When it refused to pay, he emailed thousands of patients asking for €200 and threatening to publish their therapy notes and personal details on the dark web if they didn’t pay. He ended up publishing it anyway.

As a result of this cyberattack and the extortion attempts:

*   Vastaamo’s board fired the CEO because they held him responsible for knowing about the breaches and of the shortcomings in the psychotherapy provider’s data security systems.
*   Vastaamo’s owner, who bought the practice a few months after the second breach but was not informed about it, began legal proceedings related to its purchase.
*   Vastaamo had to shut its doors because it could not meet its financial obligations.
*   The Finnish government contemplated expanding the options for individuals to change their social security number in certain circumstances, such as the aftermath of a hacking incident.
*   At least one suicide has been linked to the case.

Now the attacker has been convicted. 26-year-old Julius Kivimäki has been sentenced to six years and three months in prison. Kivimäki, known online as Zeekill, was one of the leading members of several groups of teenage cybercriminals which caused chaos between 2009-2015. One of those groups was the infamous Lizard Squad.

At the age of 17, Kivimäki was convicted of more than 50,000 computer hacks and sentenced to a two-year prison sentence, which was suspended because he was 15 and 16 when he carried out the crimes in 2012 and 2013.

Despite the conviction, the Vastaamo case is not over as civil court cases are now likely to begin to seek compensation for the victims of the hack.

 Psychotherapy practice hacker gets jail time after extorting patients, publishing personal therapy notes online 

Four major wireless carriers have been fined by the FCC for sharing access to customers’ location data without consent.

After four years of investigation, the Federal Communications Commission (FCC) has concluded that four of the major wireless carriers in the US violated the law in sharing access to customers’ location data.

The FCC fined AT&T, Sprint, T-Mobile, and Verizon a total of almost $200 million for “illegally sharing access to customers’ location information without consent and without taking reasonable measures to protect that information against unauthorized disclosure.”

The fines are divided up into $12 million for Sprint, $80 million for T-Mobile (which has now merged with Sprint), more than $57 million for AT&T, and an almost $47 million for Verizon.

From the press release it becomes apparent that the FCC considers real-time location data some of the most sensitive data in a carrier’s possession. Each of the four major carriers was found to be selling its customers’ location information to “aggregators,” who then resold access to such information to third-party location-based service providers.

The investigation by the FCC was set in motion by public reports like the ones in the New York Times, Vice.com, and a letter from Sen. Ron Wyden to the FCC. All pointed out that anyone could get location information about almost any US phone if they were willing to pay an unauthorized source.

The FCC press release specifically mentions a location-finding service operated by Securus, a provider of communications services to correctional facilities, as a source that provided the possibility to track people’s location.

The US law, including section 222 of the Communications Act, requires carriers to take reasonable measures to protect certain customer information, including location information.

The wireless carriers attempted to offload their obligation to obtain customer consent onto the downstream recipients of the location information. The end result was a failure in which no valid customer consent was obtained. And even though the carriers were aware of this, they continued to sell access to location information without taking reasonable measures to protect it from unauthorized access.

As reported by Krebs on Security, one of the data aggregation firms, LocationSmart, had a free, unsecured demo of its service online that anyone could abuse to find the near-exact location of virtually any mobile phone in North America.

Spokespersons of Verizon and AT&T both indicated to BleepingComputer that they felt as if they were taking the blame for another company’s failure to obtain consent.

T-Mobile said in a statement to CNN that it discontinued the location data-sharing program over five years ago. The company wanted to make sure first that critical services like roadside assistance, fraud protection, and emergency response would not suffer any negative consequences if it did.

All three companies indicated they will appeal the order. We’ll keep you posted on any new developments.

Malwarebytes Premium earned "Product of the Year" from AVLab for repeatedly blocking 100% of malware samples used in third-party testing.

After blocking 100% of “in-the-wild” malware samples that were deployed in multiple, consecutive third-party tests conducted by the AVLab Cybersecurity Foundation, Malwarebytes Premium Security has earned “Product of the Year.”

The recognition cements Malwarebytes Premium Security’s perfect record of repeatable, trusted, and proven protection for users. It also comes alongside an additional AVLab certification for “Top Remediation Time.”

The latest results are part of AVLab’s regular “Advanced In-The-Wild Malware Test.”

For the March 2024 evaluation, AVLab tested 459 unique malware samples against 13 cybersecurity products. Malwarebytes Premium Security detected 459/459 malware samples, with a remediation time of 20 seconds—a full 13 seconds faster than the industry average.

ThreatDown, powered by Malwarebytes, also participated in AVLab’s March evaluation, where it similarly blocked 100% of malware samples with a remediation time of 17 seconds.

Three cybersecurity vendors failed to block 100% of the malware samples deployed: Bitdefender, ESET, and Panda.

AVLab’s evaluations, which are performed every other month by a team of cybersecurity and information security experts, are constructed to test and compare cybersecurity vendors against the latest malware that is currently being used by adversaries and threat actors. To ensure that the organization’s evaluations reflect current cyberthreats, each round of testing follows three steps:

1.  **Collecting and verifying in-the-wild malware**: AVLab regularly collects malware samples from malicious and active URLs, testing the malware samples to understand their impact to networks and endpoints.
2.  **Simulating a real-world scenario in testing**: To recreate how a real-life cyberattack would occur, AVLab uses the Firefox web browser to engage with the known, malicious URLs collected in the step prior. In the most recent test, AVLab emphasized the potential for these URLs to be sent over instant messaging platforms, including Discord and Telegram.
3.  **Incident recovery time assessment**: With the various cybersecurity products installed, AVLab measures whether the evaluated product detects a malware sample, when it detects a sample, and how long it took to detect that sample. The last metric is referred to as “Remediation Time.”

Malwarebytes is proud to receive “Product of the Year” and “Top Remediation Time” from AVLab, and is thankful to the third-party tester for its important work in the industry.

The FBI sent out a warning about fraudsters that trick victims into signing up for an expensive verification process on dating sites

The FBI has warned of fraudsters targeting users of dating websites and apps with “free” online verification service schemes that turn out to be very costly.

Instead of being free, as advertised, the verification schemes involve steep monthly subscription fees, and will steal personal information on the side.

The scammers collect the information entered by victims at registrations and use it to commit further fraudulent activity such as identity theft or selling the information on the dark web. The stolen information may include email addresses, phone numbers, and even credit card information.

The scam works like this: The scammer initiates contact on a dating website or app, but then quickly asks the victim to move the conversation to a more private, encrypted platform.

Once there, the scammer will recommend a verification link that supposedly provides protection against predators like sex offenders and serial killers. This verification website asks the victim to provide their name, phone number, email address, and credit card number to complete the process.

After completing the registration, the victim is redirected to a shady dating site that charges hefty monthly fees to the victim’s credit card. These charges show up on the credit card statement as a company the victim has never heard of.

The personal information the victim gives the scammers is useful because it allows them to defraud the victims even more. Whether the scammers are the same ones, or others who have bought the information on the dark web makes no difference to the victims.

**Avoid falling victim**

There are some pointers that may help you to fall victim to scammers such as these:

*   Stay on the platform of your choice. If someone contacts you and wants to continue the conversation elsewhere, that should be a red flag. We saw the same when we discussed scams on Airbnb: It is in the scammers’ interest that the fraud takes place on a platform under their control, where they can’t be as easily tracked.
*   Don’t click on links, downloads or attachments sent to you by strangers. Even if you have been in contact with someone for some time on the internet, they are still strangers. Sometimes they will get to the point fast, but in pig butchering scams for example, the contact can be ongoing for quite a while.
*   If you are contacted by someone and they come across as untrustworthy or suspicious, report them to the platform’s administrators. You may prevent others from falling victim to the scammers.
*   Don’t provide someone you have just met with personal details and information.
*   Monitor your credit card statements and bank accounts for irregularities and contact your bank if you see payments you don’t recognise.
*   Avoid websites that use scare tactics to trick you into registering for a service. At least do a background check to find out if they are legitimate and live up to their promises.
*   Consider identity monitoring. This alerts you if your personal information is found being traded illegally online, and helps you recover after.

Health insurance giant Kaiser has announced it will notify millions of patients that it shared their data with advertisers.

Health insurance giant Kaiser has announced it will notify millions of patients about a data breach after sharing patients’ data with advertisers.

Kaiser said that an investigation led to the discovery that “certain online technologies, previously installed on its websites and mobile applications, may have transmitted personal information to third-party vendors.”

In the required notice with the US government, Kaiser lists 13.4 million affected individuals. Among these third-party ad vendors are Google, Microsoft, and X. Kaiser said it subsequently removed the tracking code from its websites and mobile apps.

A tracking pixel is a piece of code that website owners can place on their website. The pixel collects data that helps businesses track people and target adverts at them. That’s nice for the advertisers, but the information gathered by these pixels tells them a lot about your browsing behavior, and a lot about you.

This kind of data leak normally happens when a website includes sensitive information in its URLs (web addresses). The URLs you visit are shared with the company that provides the tracking pixel, so if the URL contains sensitive information it will end up in the hands of the tracking company. The good news is that while it’s easy for websites to leak information like this, there is no suggestion that tracking pixel operators are aware of it, or acting on it, and it would probably be hugely impractical for them to do so.

The leaked data includes member names and IP addresses, as well as information that could indicate if members were signed into a Kaiser Permanente account or service, how they interacted with it, how they navigated through the website and mobile applications, and what search terms they used in the health encyclopedia.

A spokesperson said that Kaiser intends to begin notifying the affected current and former members and patients who accessed its websites and mobile apps in May.

Not so long ago, we reported how mental health company Cerebral failed to protect sensitive personal data, and ended up having to pay $7 million. Also due to tracking pixels, so this is a recurring problem we are likely to see lots more of. Research done by TheMarkup in June of 2022 showed that Meta’s pixel could be found on the websites of 33 of the top 100 hospitals in America.

 A week in security (April 22 &#8211; April 28) 

The FTC is paying Ring customers in the US a totoal of $5.6 million over charges that the company allowed employees to access private videos.

Amazon’s Ring has settled with the Federal Trade Commission (FTC) over charges that the company allowed employees and contractors to access customers’ private videos, and failed to implement security protections which enabled hackers to take control of customers’ accounts, cameras, and videos.

The FTC is now sending refunds totaling more than $5.6 million to US consumers as a result of the settlement.

Ring LLC, which was purchased by Amazon in February 2018, sells internet-connected, home security cameras and video doorbells.

However, in a shocking lapse of security protection, it turned out that every single person working for Amazon Ring, whether they were an employee or a contractor, was able to access every single customer video, even when it wasn’t necessary for their jobs.

But that wasn’t the only issue. In May 2023, the FTC stated that:

> “Ring deceived its customers by failing to restrict employees’ and contractors’ access to its customers’ videos, using its customer videos to train algorithms without consent, and failing to implement security safeguards. These practices led to egregious violations of users’ privacy.”

The FTC gave the example of one employee who, over several months, viewed thousands of video recordings belonging to female users of Ring cameras that were pointed at intimate spaces in their homes such as their bathrooms or bedrooms. This didn’t stop until another employee discovered the misconduct.

The FTC is now sending 117,044 PayPal payments to US customers who had certain types of Ring devices, such as indoor cameras, during periods when the FTC alleges unauthorized users may have had access to customer videos. Customers should redeem their PayPal payment within 30 days.

“The FTC identified eligible Ring customers based on data provided by the company,” the agency told BleepingComputer, clarifying that Ring users “were eligible for a payment if their account was vulnerable because of privacy and security problems alleged in the complaint.”

Consumers who have questions about their payment should contact the refund administrator, Rust Consulting, Inc., at 1-833-637-4884, or visit the FTC website to view frequently asked questions about the refund process.

**Beware of scammers**

As always, you can expect scammers to take advantage of this news. So, it’s important to know that the FTC never asks people to pay money or provide account information to get a refund.

A payment or claim form sent as part of an FTC settlement will include an explanation of, and details about, the case. The case will be listed at ftc.gov/refunds, along with the name of the company issuing payments and a phone number for questions.

The FTC only works with four private companies to handle the refund process:

*   Analytics Consulting, LLC
*   Epiq Systems
*   JND Legal Administration
*   Rust Consulting, Inc.

Before sending any PayPal payment, the FTC will send an email from the subscribe@subscribe.ftc.gov address to issue a payment recipient. Once payments have been issued, PayPal will send an email telling recipients about their refund.

 Ring agrees to pay $5.6 million after cameras were used to spy on customers 

The US Senate has approved a bill that will ban TikTok, unless it finds a new owner, bringing it one step closer to being signed into law.

The US Senate has approved a bill that would effectively ban TikTok from the US unless Chinese owner ByteDance gives up its share of the immensely popular app.

Social video platform TikTok has experienced explosive growth since it first appeared in 2017, and is now said to have well over 1.5 billion users, with an estimated 170 million of them in the US.

Essentially, the bill says that TikTok has to find a new owner that is not based in a foreign adversarial country within the next 180 days or face a ban until it does comply. President Biden has committed to sign it into law as soon as it reaches his desk.

Since 2020, several governments and organizations have banned, or considered banning, TikTok from their staff’s devices, but a complete ban of an internet app would be a first in the US.

For a long time now, TikTok has been battling to convince politicians that it operates independently of ByteDance, which allegedly has deep ties to the Chinese Communist Party (CCP). For example, TikTok has repeatedly claimed the Chinese government has never demanded access to US data and that TikTok would not comply if it did.

While ByteDance denies any direct links to the Chinese Communist Party, a former executive at TikTok’s parent company claimed in court documents that the CCP had access to TikTok data, despite US storage of the data. The allegations came up in a wrongful dismissal lawsuit filed in May of 2023 in the San Francisco Superior Court.

The Electronic Frontier Foundation (EFF), an international non-profit digital rights group based in the US, says it opposes this bill, mainly because it is afraid that TikTok will not be the last app to face this type of ban.

TikTok also encouraged its users and creators to express their opposition to the bill. Last week, the social media company said the bill would:

> “Trample the free speech rights of 170 million Americans, devastate seven million businesses, and shutter a platform that contributes $24 billion to the US economy, annually.”

Chinese officials reportedly said the government would “firmly oppose” any forced sale of TikTok because it would “seriously undermine the confidence of investors from various countries, including China, to invest in the United States.”
