Disclosure context

About Handala

Handala is a recently emerged ransomware group that first appeared in May 2024, primarily motivated by financial gain with potential geopolitical overtones given their targeting patterns. The group's country of origin remains unclear, though their focus on Israeli targets alongside Western nations suggests possible Middle Eastern connections or sympathies, and it is unknown whether they operate as a standalone group or utilize a Ransomware-as-a-Service model. Limited public information exists regarding their specific attack methodologies, initial access vectors, or technical capabilities, though their rapid accumulation of 164 documented victims suggests they employ effective compromise techniques across multiple sectors including technology, government, energy, and healthcare organizations. The group has demonstrated a clear preference for targeting victims in Israel, the United States, and the United Kingdom, with additional activity observed in Iran and the UAE, indicating either opportunistic targeting or strategic selection based on geopolitical considerations. Given their recent emergence and continued victim acquisitions throughout 2024, Handala appears to remain active, though comprehensive technical analysis and law enforcement reporting on their operations remain limited due to their relatively short operational history. The group has been linked to 182 public disclosures across our corpus. First observed on a leak site on May 26, 2024; most recent post April 15, 2026. The operation is currently active.

If your organisation is affected

A listing by Handala means Tosaf 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-NL (Netherlands), as required for your jurisdiction.
Monitor for the data appearing on Handala'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. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
