Disclosure context

About Black Basta

Black Basta is a financially motivated ransomware group that emerged in April 2022 and has since compromised approximately 800 organizations worldwide. The group operates as a Ransomware-as-a-Service (RaaS) model with suspected ties to the now-defunct Conti ransomware operation, though their exact country of origin remains unconfirmed by law enforcement agencies. Black Basta primarily gains initial access through phishing campaigns, exploitation of known vulnerabilities, and credential stuffing attacks, subsequently deploying their custom ransomware that employs ChaCha20 encryption algorithm and employs double extortion tactics by exfiltrating sensitive data before encryption and threatening to publish it on their leak site if ransom demands are not met. The group has demonstrated a preference for targeting organizations in the United States, United Kingdom, Germany, Canada, and Italy, with a particular focus on business services, manufacturing, technology, healthcare, and agriculture sectors. Notable victims have included various healthcare systems and manufacturing companies, though specific ransom amounts and high-profile attacks have not been widely disclosed in public law enforcement advisories. As of 2024, Black Basta remains an active threat with continued operations and regular updates to their leak site indicating ongoing compromise activities. The group has been linked to 1,323 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 Black Basta means rembe.de 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, CERT-Bund (Germany), as required for your jurisdiction.
Monitor for the data appearing on Black Basta'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.

We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable.
