ALPHV, also known as BlackCat or Noberus, is a sophisticated ransomware-as-a-service operation that emerged in November 2021 and quickly became one of the most prolific ransomware groups globally, driven by financial motivations and responsible for compromising over 930 victims worldwide. The group is believed to be operated by Russian-speaking cybercriminals and represents an evolution of the BlackMatter ransomware operation, operating under a RaaS model that recruits experienced affiliates from other disbanded ransomware groups. ALPHV employs a multi-faceted attack methodology utilizing various initial access vectors including compromised Remote Desktop Protocol credentials, phishing campaigns, and exploitation of unpatched vulnerabilities, followed by deployment of their Rust-based ransomware payload that supports both Windows and Linux environments, while consistently employing double extortion tactics that involve data theft prior to encryption and threats to publish stolen information on their leak site. Notable campaigns include high-profile attacks against critical infrastructure and major corporations across healthcare, finance, and energy sectors, with the group demanding ransoms ranging from hundreds of thousands to millions of dollars, prompting the FBI and CISA to issue multiple advisories warning of their targeting of critical infrastructure organizations. As of early 2024, ALPHV remains active despite ongoing law enforcement efforts, continuing to evolve their tactics and maintain their position as one of the most significant ransomware threats globally. The group has been linked to 931 public disclosures across our corpus. First observed on a leak site on September 9, 2021; most recent post March 3, 2024. The operation is currently inactive.

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.
