The BianLian Extortion Gang's Attack on CMC Marine

The BianLian extortion gang has attacked CMC Marine. CMC Marine is a stabilizing and control systems manufacturer for yachts and superyachts. It is headquartered in Poole, England. BianLian posted CMC Marine to its data leak site on July 29th, claiming to have stolen 2TB of HR, accounting, financial, personal, and business data.

BianLian: A Notorious Cybercriminal Organization

BianLian is an infamous cybercriminal organization involved in data extortion. Since June 2022, they have targeted various critical infrastructure sectors in the United States. Additionally, they have extended their attacks to include Australian critical infrastructure sectors, as well as professional services and property development domains.

Method of Attack

To gain unauthorized access to their victims' systems, the group exploits valid Remote Desktop Protocol (RDP) credentials. They employ open-source tools and command-line scripts to carry out reconnaissance and gather credentials. Victim data is then extracted using File Transfer Protocol (FTP), Rclone, or Mega.

Extortion Tactics

Subsequently, the BianLian group proceeds to extort money from their victims by threatening to expose the obtained data unless a payment is made. Initially, the group utilized a double-extortion approach, which involved encrypting victims' systems after data exfiltration. However, starting around January 2023, they primarily focused on data exfiltration-based extortion.

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.
