Disclosure context

About Blackmatter

BlackMatter is a financially motivated ransomware-as-a-service operation that emerged in July 2021, positioning itself as a successor to the defunct DarkSide and REvil ransomware groups. The group is believed to operate from Russia or former Soviet states, recruiting Russian-speaking affiliates through underground forums and operating under the RaaS model where core developers provide ransomware tools to affiliate operators in exchange for a percentage of ransom payments. BlackMatter employs sophisticated attack methodologies including initial access through compromised VPN credentials, phishing campaigns, and exploitation of known vulnerabilities, followed by deployment of custom tools for lateral movement and credential harvesting before deploying their ransomware payload that uses a combination of RSA and Salsa20 encryption algorithms, while also implementing double extortion tactics by exfiltrating sensitive data prior to encryption and threatening public release if ransom demands are not met. Notable campaigns include attacks against critical infrastructure sectors particularly targeting agricultural cooperatives, technology companies, and financial institutions across the United States, Germany, and the United Kingdom, with ransom demands reportedly ranging from hundreds of thousands to millions of dollars. The group announced their dissolution in November 2021, claiming to cease operations due to pressure from law enforcement and government agencies, though security researchers believe the core operators likely transitioned to other ransomware variants or rebranded under different names. The group has been linked to 42 public disclosures across our corpus. First observed on a leak site on August 1, 2020; most recent post November 4, 2021. The operation is currently inactive.

If your organisation is affected

A listing by Blackmatter means g-able.com appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Monitor for the data appearing on Blackmatter's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
