Disclosure context

About ALPHV/BlackCat

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 1,662 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.

If your organisation is affected

A listing by ALPHV/BlackCat means Ursel Phillips Fellows Hopkinson 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.
  • Report the incident to your national CERT, CCCS (Canada), as required for your jurisdiction.
  • Monitor for the data appearing on ALPHV/BlackCat'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.
