Disclosure context

About safepay

The Safepay ransomware group is a newly emerged threat actor first observed in November 2024, demonstrating rapid operational scale with 444 documented victims in a short timeframe, indicating financially motivated cybercriminal activity. Due to the group's recent emergence, publicly documented information about their country of origin, affiliations, and operational model remains limited among established threat intelligence sources. Given the recency of their appearance and lack of detailed technical analysis from major security firms, their specific attack methodologies, initial access vectors, and encryption techniques have not been comprehensively documented in public threat intelligence reporting. The group has demonstrated a broad targeting approach across multiple sectors including manufacturing, technology, education, and healthcare, with primary focus on victims in the United States, Germany, Canada, the United Kingdom, and Australia, though no specific high-profile campaigns or notable incidents have been publicly attributed to them by major security vendors or law enforcement agencies. As of the latest available intelligence, Safepay appears to remain active, though comprehensive threat profiling is limited due to the group's recent emergence and the current lack of detailed technical analysis from established cybersecurity research organizations. The group has been linked to 779 public disclosures across our corpus. First observed on a leak site on November 19, 2024; most recent post September 15, 2026. The operation is currently active.

If your organisation is affected

A listing by safepay means ara-lyss.ch 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, NCSC-CH (Switzerland), as required for your jurisdiction.
Monitor for the data appearing on safepay'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.
