Cactus Ransomware Group's Attack on Asbury Automotive Group
Cactus ransomware group claimed an attack against Asbury Automotive Group. The group has exfiltrated 62 GB of data, including certificates, passport applications, and Personally Identifiable Information (PII) documents. Asbury Automotive Group is a company based in Atlanta that operates auto dealerships in various parts of the United States.
Cactus's Operation Tactics
Cactus has been in operation since at least March 2023. Cactus has been observed employing known vulnerabilities within VPN appliances to initiate an initial breach. Once gaining entry to the network, Cactus operators engage in activities such as enumerating local and network user accounts and identifying accessible endpoints. They then proceed to generate new user accounts and utilize custom scripts for the automated rollout and activation of the ransomware encryptor through scheduled tasks.
Unique Characteristics of the Ransomware
It is noteworthy that the ransomware encryptor utilized by Cactus exhibits a unique characteristic – it necessitates a decryption key for the execution of the binary, likely implemented to evade detection by anti-virus software. This decryption key is concealed within a file containing random text named ntuser.dat, which is loaded through a scheduled task.
Recent Ransomware Attacks
The Recent Ransomware Attacks (RRA) site acts as a watchtower, providing you with near real-time ransomware tracking of attacks, groups and their victims. Given threat actors’ overarching, lucrative success so far, ransomware attacks have become the most ubiquitous, and financially and informationally impactful cyber threat to businesses and organizations today.
The site’s data is generated based on hosting choices of real-world threat actors, and a handful of other trackers. While sanitization efforts have been taken, we cannot guarantee 100% accuracy of the data. Attack updates will be made as source data is reported by reputable sources. By viewing, accessing, or using RRA you acknowledge you are doing so at your own risk.
