Ragnar Locker Ransomware Gang Attacks Comeca

The Ragnar Locker ransomware gang has attacked Comeca. Comeca was founded in 1952 and is headquartered in Magny-les-Hameaux, France. Over the years, it has established itself as a leading provider of electrical equipment and automation systems. The company has a global presence and serves customers in diverse sectors. Ragnar Locker posted Comeca to its data leak site on September 25th but provided no further details.

RagnarLocker's Modus Operandi

RagnarLocker is not a traditional RaaS. They first emerged in December of 2019 and were assessed to be related to or working in cooperation with Maze and MountLocker operators. RagnarLocker typically compromises victim networks through vulnerable Remote Desktop Protocol (RDP) software, a common ransomware technique. RagnarLocker was increasingly active in 2022, but attack volume has dripped off significantly in Q1-2023.

Ransom Demands and Techniques

RagnarLocker ransom demands vary and have been observed to exceed $10 million. Ragnar Locker has both Windows and Linux versions that actively detect and bypass security tools on the targeted network, as well as scanning for virtual-based machines, and any remote management solutions. IT encrypts with a custom Salsa20 algorithm and has been observed terminating services that managed service providers (MSPs) to remotely protect and manage customer networks.

Targeting and Extortion Strategies

RagnarLocker is opportunistic and is assessed to target based on a victim’s ability to pay large ransom demands, focusing on the manufacturing, energy, financial services, government, and information technology sectors. RagnarLocker engages in data exfiltration for double extortion and maintains a leaks site called “Wall of Shame.” RagnarLocker will delete VSS Shadow Copies to thwart encryption rollback.

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.
