Disclosure context

About malekteam

malekteam is a relatively new ransomware group that emerged in December 2023, operating with apparent financial motivations based on their targeting patterns and small-scale operations. The group's origin and affiliations remain largely undocumented in public threat intelligence reporting, though their limited scope of operations suggests they operate as an independent entity rather than part of a larger ransomware-as-a-service ecosystem. With only seven known victims documented to date, malekteam appears to focus their attacks primarily on targets in Israel and Switzerland, with a preference for business services and healthcare sectors, though specific details about their initial access vectors, encryption methods, and whether they employ data exfiltration tactics prior to encryption have not been publicly documented by major security firms or law enforcement agencies. Due to the group's recent emergence and limited public reporting, notable campaigns and high-profile victims have not been extensively documented in open-source intelligence reports from established security researchers. The group's current operational status remains unclear given the limited public documentation of their activities since their emergence in late 2023. The group has been linked to 7 public disclosures across our corpus. First observed on a leak site on December 24, 2023; most recent post April 5, 2024. The operation is currently inactive.

Also tracked as: malek team.

If your organisation is affected

A listing by malekteam means ZIV Hospital 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-IL (Israel), as required for your jurisdiction.
Monitor for the data appearing on malekteam'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.
