1. Data Breaches

The most recent T-Mobile API hack affected 1M Google Fi users, Vice Media confirmed a breach including SSN, TruthFinder and Instant Checkmate data loss counts in dozens on millions of users 

  1. TruthFinder and Instant Checkmate Data Breach Affects 20 Million Customers
    Owners of the TruthFinder and Instant Checkmate background check services, PeopleConnect, confirmed a data breach after hackers leaked a 2019 backup database containing the information of millions of customers. On January 21st, the data was leaked on the Breached hacking and data breach forum. The exposed data includes email addresses, hashed passwords, first and last names, and phone numbers. PeopleConnect immediately launched an investigation and found no evidence of their network being breached. The company has engaged with a third-party cybersecurity firm and warns customers to be on the lookout for targeted phishing attacks. The incident is believed to be an "inadvertent leak or theft of a particular list."
  2. Vice Media Data Breach Affects 1700 People
    A data breach at Vice Media leaked sensitive information and financial data of more than 1,700 people. The company was alerted in March 2022 and hired a cybersecurity firm to investigate the incident. The investigation found that hackers managed to break into an internal Vice email account. The breach involved Social Security numbers, financial account numbers, credit and debit card numbers, security codes, access codes, passwords, and PINs for accounts. The company did not respond to requests for comment on why it took nearly a year to complete the process. Victims are being offered 12 months of credit and identity monitoring services as well as identity restoration services through Equifax.
  3. Google Fi Data Breach Linked To T-Mobile hack affects 1M users at least
    Google’s cell network provider Google Fi confirmed a data breach after being informed by its primary network provider of suspicious activity relating to a third-party support system containing a “limited amount” of Google Fi customer data. The timing of the notice suggests the breach is linked to the recent T-Mobile hack. No further details have been provided by Google at this time.

2. Research

Adobe Acrobat is on the focus of research again, ChatGPT applied to AWS policies review, Facebook 2FA hacked

  1. Adobe Acrobat Reader has been the latest target in the fuzzing campaign aimed at popular PDF readers. A use-after-free vulnerability (CVE-2023-21608) was discovered and exploited to achieve Remote Code Execution. The exploit was acquired by Zero Day Initiative (ZDI) along with the vulnerability. The 64-bit version of the Adobe Reader was also affected, but the bug proved to be useless for 64-bit exploitation due to the presence of consecutive NULL bytes in the addresses. The exploit code and more information about the bug can be found at We recommend this write-up for everyone who wants to do a deep-dive into binary exploitation. Source:
  2. A 2FA bypass has been discovered in Facebook's new account center APIs. The settings page has strict access control, but the way it was implemented could lead to account take over or 2FA bypass. For example, if the page does not verify emails properly, someone might be able to send a verification code to the target's email and brute force it, making the email detached from the target's account and attached to theirs. If a number is used for 2FA and it gets detached from the target's account, 2FA won't exist on their account any longer. Combining removing the email with a merge functionality could result in Account Take Over (ATO). This type of 2FA bypass is a clever approach, but it is caused by bad application design. Source:
  3. CloudGPT is a tool that utilizes ChatGPT to analyze AWS policies for vulnerabilities. It works by pulling your AWS policies and checking for vulnerabilities by asking ChatGPT. The tool will soon be released and a webcast is coming soon. All you have to do is set your OpenAI key and configure your AWS CLI. Source code:
