Details of the Ransomware Attack

The cybercrime group Fsociety has claimed responsibility for a significant data breach targeting SBC Global Services Inc. The attack resulted in the exfiltration of approximately 1 terabyte of confidential information and user data. This data has since been published on Fsociety's dark web leak site, indicating a severe security breach.

Vulnerabilities and Potential Breach Methods

Given the nature of SBC Global Services Inc.'s operations and its reliance on legacy domain systems like, the company's cybersecurity defenses might have vulnerabilities typical of older digital infrastructures. These can include outdated security protocols, insufficient segmentation of network resources, or legacy systems that no longer receive regular security updates. Such factors could have provided Fsociety with multiple attack vectors to exploit, such as phishing, exploiting known vulnerabilities, or other forms of social engineering.

Profile of the Attacker: Fsociety

Fsociety is a relatively new player in the realm of cyber threats, first identified in 2016. The group is known for using Python-based ransomware, which is part of the open-source EDA2 project. Their ransomware is capable of infecting network share resources, downloading and executing arbitrary payloads, and includes anti-VM evasion techniques. The group's ability to adapt and modify their attack methods using easily accessible open-source tools makes them particularly dangerous.


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.
