BianLian, White Rabbit, and Mario Ransomware Gangs Team Up for Mega-Extortion

In the shadowy world of cybercrime, alliances are formed not in boardrooms, but in the encrypted corners of the dark web. Recently, a sinister coalition has emerged, uniting three formidable ransomware gangs – BianLian, White Rabbit, and Mario – in a spree of cyber-extortion. Their collaboration marks a chilling evolution in ransomware tactics, signifying a major shift in the cyber-threat landscape.

The union of these three gangs was first detected during a joint Digital Forensics & Incident Response (DFIR) engagement involving law enforcement and one of the leading investment organizations in Singapore, Resecurity, Inc. (USA). This collaboration, facilitated by Initial Access Brokers (IABs) in the dark web, represents a growing trend where disparate ransomware operators band together to amplify their extortion capabilities.

White Rabbit, known for its signature payload-evasion tactics and a penchant for targeting financial institutions, has notoriously integrated the Ransomhouse Telegram Channel in its ransom notes. The group’s methods echo those of the Egregor Ransomware family, indicating possible affiliations or shared methodologies among these cybercriminal entities.

Meanwhile, BianLian has been making waves with its sophisticated ransomware attacks, particularly targeting organizations in multiple U.S. critical infrastructure sectors. Their modus operandi involves using valid Remote Desktop Protocol (RDP) credentials and open-source tools for discovery and credential harvesting, followed by extortion through the threat of data release.

Mario Ransomware, the newest addition to this cybercrime syndicate, has already made a name for itself with attacks that parallel those of White Rabbit. Their collaboration is evident in shared ransom notes and tactics, suggesting a deepening partnership within this cyber-extortion trinity.

The collaboration of these groups on the dark web has sparked a proliferation of ransomware attacks, with negotiators specializing in coercing victim payments. This emergence of a ‘ransomware fraternity’ underscores the necessity for heightened cybersecurity vigilance and proactive defense strategies.

The alliance of BianLian, White Rabbit, and Mario ransomware gangs represents a significant escalation in cyber threats. Organizations must fortify their defenses against these sophisticated attackers. This includes regular system updates, robust threat detection mechanisms, and comprehensive employee training to combat social engineering attacks.
