The US Cybersecurity and Infrastructure Security Agency (CISA) has added a JetBrains vulnerability to its Known Exploited Vulnerabilities (KEV) catalog, noting evidence of active exploitation. The JetBrains flaw is a critical authentication bypass problem in the TeamCity On-Premises software that enables unauthenticated attackers to completely take over target servers. It is tracked as CVE-2024-27198 and has a severity score of 9.8.

Researchers discovered that hackers can steal a Tesla Model 3 by conducting a Man-in-The-Middle (MiTM) phishing attack on car owners' Tesla accounts. The researchers carried out the attack using the 4.30.6 version of the Tesla App, which serves as the car's key, and version 11.1 2024.2.7 of the underlying Tesla software. Through the attack, the researchers were able to get a new "phone key" to unlock the Tesla vehicle. The study reveals that connecting the car to a new phone lacks adequate authentication security.

A team of experts at the US Department of Energy's (DOE) Pacific Northwest National Laboratory (PNNL) presented a new approach to protecting the electric grid against cyberattacks. Instead of protecting the grid and its many components piece-by-piece, the team is developing a tool capable of quickly sorting and prioritizing cyber threats. The goal is to provide grid operators with a clear blueprint for identifying and addressing the most serious threats first. This article continues to discuss the team's approach to protecting the electric grid against cyberattacks.

According to Jason Parker, an independent cybersecurity researcher, a popular tool used by many state and local governments to manage public records requests had flaws that could have enabled hackers to download unsecured files associated with records inquiries, including personal information such as IDs, fingerprints, medical reports, and more. The vulnerabilities could have also let hackers trick the system into allowing individuals to edit or change the metadata of records requests without administrators' knowledge.
