Attack summary

Severity: medium — Maxxis is a large multinational manufacturing and distribution company with global operations and 30,000+ employees. However, the leak post contains only general company background information with no stated proof files, no specific data exfiltration details, and no operational disruption claims. Classification is elevated from 'low' due to the scale and sensitivity of supply chain/operational data a tire manufacturer would hold, but remains 'medium' pending confirmation of actual compromise sco

Blacksuit claims to have compromised Maxxis International. The leak post does not specify whether data was exfiltrated, encrypted, or both, nor does it detail what data categories are at stake.

Disclosure context

About Blacksuit

Blacksuit is a financially motivated ransomware group that emerged in June 2023, quickly establishing itself as a significant threat with 184 documented victims across multiple sectors. The group's origin and specific affiliations remain largely undocumented in public threat intelligence reports, though their operational patterns suggest they operate as an independent entity rather than a traditional RaaS model. Blacksuit primarily targets organizations through common initial access vectors and employs standard ransomware deployment techniques, though detailed technical analysis of their specific encryption methods and whether they consistently employ double extortion tactics has not been widely published by major security firms. The group has demonstrated a clear preference for targeting business services, healthcare, government, and manufacturing sectors, with their victims predominantly located in English-speaking countries including the United States, United Kingdom, and Canada, as well as Spain and Germany. As of current reporting, Blacksuit remains an active ransomware operation with no publicly documented law enforcement disruptions or significant rebranding efforts. The group has been linked to 184 public disclosures across our corpus. First observed on a leak site on June 12, 2023; most recent post June 2, 2025. The operation is currently inactive.

If your organisation is affected

A listing by Blacksuit means Maxxis International 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 Blacksuit'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.
