What the group claims

The headquarters is located in Sinzig/Rhine, where about 30 employees can rely on more than two decades of experience and can therefore assure a competent handling of our daily and future business. With more than 1.000 m2 office space and 1.500 m2 warehouse space, our headquarters also comprise our own development department as well as a highly modern production line, on which the tuning boxes are produced according to EC-Directives.Speed-Buster® sells its tuning boxes globally in more than 50 countries with high success and in high quantities. Our clients know and appreciate that the label made in Germany is a guarantee for sophisticated and high-quality products. As a support, local distributor bases are established all around the globe. Contrary to the current tendency amongst many of our competitors, SPEED-BUSTER has decided to solely produce in Germany. This allows us to intervene in a focused manner at any time of the manufacturing process and to continuously enhance our products. The loyalty of our customers has confirmed this decision time and again.

Disclosure context

About Blackbyte

BlackByte is a ransomware-as-a-service (RaaS) operation that emerged in October 2021, primarily motivated by financial gain through double extortion tactics targeting organizations across multiple sectors. The group is suspected to operate from Russia or former Soviet states based on their use of Russian-language forums and avoidance of targeting organizations in Commonwealth of Independent States countries, though they maintain no confirmed links to other established ransomware families. BlackByte operators typically gain initial access through vulnerable Microsoft Exchange servers, phishing campaigns, and exploitation of remote desktop protocol (RDP) services, employing tools such as Cobalt Strike for lateral movement and data exfiltration before deploying their custom ransomware payload that uses AES-256 encryption with RSA-2048 key protection. The group has demonstrated particular focus on critical infrastructure sectors, with the FBI and CISA issuing joint advisories in February 2022 highlighting attacks against organizations in government, healthcare, manufacturing, and education sectors, including notable incidents affecting San Francisco's transportation authority and multiple healthcare systems across the United States. BlackByte remains active as of 2024, continuing to evolve their tactics and maintain their leak site for publishing stolen data from victims who refuse to pay ransoms. The group has been linked to 147 public disclosures across our corpus. First observed on a leak site on October 4, 2021; most recent post July 30, 2025. The operation is currently inactive.

If your organisation is affected

A listing by Blackbyte means Speed-Buster 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 Blackbyte'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.
