The world’s high ransomware gangs have created a cybercrime “cartel”
A number of of the biggest Russian ransomware cybercriminal gangs have partnered up and are sharing hacking methods, purloined data-breach data, malware code and know-how infrastructure.
Probably the most energetic collaborators are 4 teams generally known as Wizard Spider, Twisted Spider, Viking Spider and LockBit. The gangs on this cluster collectively management entry to illicit information leak websites and customized ransomware code. Additionally they affiliate with the bigger legal ransomware ecosystem, exert affect over smaller gangs and license their instruments to associates, mentioned Jon DiMaggio, chief safety strategist at Analyst1. The teams don’t seem to share earnings from legal exercise.
“They are not a cartel within the conventional sense, like oil firms which have a lock on the availability of crude,” DiMaggio defined. “However they do have know-how infrastructure, and a few are large enough to have their very own [ransomware] code. These are restricted assets.”
The teams Viking Spider and LockBit add stolen data to an information breach web site hosted and managed by Twisted Spider, in line with DiMaggio’s analysis. This data is used for phishing assaults that ship ransomware and posted to legal name-and-shame websites which might be used to embarrass and coerce victims. The gangs additionally horde shared hacking instruments and software program exploits generally known as zero-day vulnerabilities. Twisted Spider additionally operates a command-and-control server that hosts malware and hacking instruments utilized by different gangs together with Viking Spider, LockBit and a now-defunct group known as the Suncrypt Gang.
Cybercriminal gangs typically attempt to domesticate distinctive personas, and are recognized for utilizing custom-made strains of ransomware. The gangs REvil and Twisted Spider are related to Maze and Egregor ransomware, respectively. Wizard Spider is linked to Ryuk and Conti.
New clusters are extra highly effective, subtle
Hacking teams steadily collaborate, break up, shut down, rebrand and regroup. A number of teams within the so-called cartel cluster introduced a collaboration in July 2020, then disbanded in November. The brand new cluster of gangs is probably extra highly effective, DiMaggio mentioned, due to its hyperlinks to different risk actors within the cybercriminal ecosystem. For example, his analysis connects the brand new group with three further gangs, together with EvilCorp, a veteran hacking group led by Maksim Yakubets that focused distant staff through the pandemic.
DiMaggio’s analysis additionally connects the brand new ransomware collaborators with SilverFish, a hacking group many cybersecurity researchers consider is definitely FSB or SVR, the Russian intelligence teams behind the Photo voltaic Winds cyberattacks.
Some ransomware gangs are so subtle they’ve a mediation course of to deal with disputes, in line with DiMaggio and hackers aware of the method. For instance, REvil deposited a million {dollars} right into a fund hosted on a cybercriminal discussion board to ensure affiliate funds, within the hopes of attracting top-quality hackers. When the DarkSide ransomware gang abruptly ceased operations, a few of its associates weren’t paid. Cash from the legal discussion board was used to pay these associates, inflicting a dispute which was resolved utilizing inside communication instruments.
These instruments, mentioned DiMaggio, are a part of what make the teams so profitable. “They’ll resolve inevitable cash disputes shortly, then get again to work,” he mentioned.

Booming cybercrime trade
The ransomware partnership is a part of the massive and rising ransomware-as-a-service trade. Very similar to software-as-a-service, a booming trade that sells subscriptions to software program slightly than downloads, ransomware-as-a-service permits anybody to pay a price to license the know-how and expertise of a hacker. Teams like REvil and DarkSide, allegedly answerable for among the largest ransomware hacks in historical past, provided pleasant customer support and IT assist to victims.
Ransomware code is comparatively straightforward to customise. A big market of weak computer systems mixed with the pseudo-anonymity of cryptocurrency has created an setting ripe for legal exploitation, mentioned DiMaggio.
This new cartel poses contemporary challenges, mentioned DiMaggio. He worries that “a mega-group cartel” can be way more harmful than earlier teams as a result of it could have extra construction. He added, “with coordination and group, their ransomware strains may be extra harmful than anybody particular person cyberweapon.”
