About Cl0p

The Cl0p (also known as Clop) ransomware group is a financially motivated cybercriminal organization that emerged in March 2020, operating as part of the broader TA505/FIN11 threat landscape and conducting high-impact ransomware campaigns targeting organizations globally. The group is believed to operate from Russian-speaking territories and has been linked to the prolific TA505 cybercriminal consortium, functioning as a Ransomware-as-a-Service operation that collaborates with various affiliate groups to maximize their operational reach. Cl0p primarily gains initial access through exploitation of zero-day vulnerabilities in file transfer applications, phishing campaigns, and SQL injection attacks, employing double extortion tactics by exfiltrating sensitive data before deploying their custom ransomware payload, which uses strong encryption algorithms to render victim systems inoperable. The group has been responsible for several high-profile campaigns, most notably their exploitation of zero-day vulnerabilities in MOVEit Transfer software in 2023, which affected hundreds of organizations worldwide including major corporations and government entities, and their previous campaigns targeting Accellion FTA and other file transfer solutions that resulted in the compromise of sensitive data from numerous high-value targets. Cl0p remains active as of 2024, continuing to evolve their tactics and maintain their position as one of the most prolific ransomware groups globally, with over 1,490 documented victims primarily concentrated in the United States, Canada, United Kingdom, Germany, and Australia across technology, manufacturing, transportation, and consumer services sectors. The group has been linked to 1,490 public disclosures across our corpus. First observed on a leak site on March 13, 2020; most recent post February 14, 2026. The operation is currently active.

Attack summary

Severity: high — Data is listed as published by Cl0p, a group known for mass exfiltration campaigns. Hudson Sustainable Group manages over $13 billion in deployed capital; exposed data likely includes sensitive financial, investment, and counterparty information. While no specific data inventory or volume was confirmed in the post, the published status and nature of the firm's operations (asset management, institutional finance) elevate this to high severity.

Cl0p claims to have published data belonging to Hudson Sustainable Group, with the disclosure status listed as data_published; no ransom amount or data size was stated, but the group's standard methodology involves both exfiltration and threatened publication of sensitive corporate and financial records.
