Profile of the Ransomware Group: BianLian

BianLian, originally known as a banking trojan, has evolved into a formidable ransomware group with a global reach, particularly impacting organizations in North America and Europe. The group is known for its sophisticated attack vectors, primarily through compromised RDP credentials and advanced persistent threats (APTs). BianLian distinguishes itself by focusing on exfiltration-based extortion, threatening severe financial and reputational damage to enforce ransom payments.

Potential Vulnerabilities and Attack Penetration

MEL Aviation’s significant reliance on digital systems for managing its extensive data and operational logistics may have exposed vulnerabilities that BianLian exploited. The initial breach could have been facilitated through compromised network credentials or by exploiting unpatched security flaws within the company’s IT infrastructure.


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.
