Disclosure context

About blackbasta

Black Basta is a financially motivated ransomware group that emerged in April 2022 and has rapidly established itself as a significant threat actor, compromising over 500 organizations globally within its first two years of operation. The group is suspected to have ties to Russia-based cybercriminal networks and operates as a Ransomware-as-a-Service (RaaS) model, recruiting affiliates to conduct attacks while the core group maintains the ransomware infrastructure and negotiates with victims. Black Basta primarily gains initial access through phishing campaigns, exploitation of unpatched vulnerabilities, and compromised Remote Desktop Protocol (RDP) credentials, then deploys custom tools and living-off-the-land techniques to move laterally through networks before deploying their ransomware payload that uses ChaCha20 encryption. The group employs double extortion tactics, stealing sensitive data before encryption and threatening to publish it on their leak site if ransom demands are not met. Notable campaigns include attacks on major manufacturing companies, healthcare organizations, and critical infrastructure entities primarily across the United States, United Kingdom, Germany, Canada, and Italy, with the group showing particular focus on business services, manufacturing, technology, agriculture and food production, and transportation/logistics sectors. As of 2024, Black Basta remains active and continues to evolve its tactics, techniques, and procedures while maintaining a steady pace of victim recruitment and ransom collection operations. The group has been linked to 523 public disclosures across our corpus. First observed on a leak site on April 26, 2022; most recent post January 11, 2025. The operation is currently inactive.

If your organisation is affected

A listing by blackbasta means medion.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 blackbasta'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.
