About the Killsec group

KillSec originated as a hacktivist group aligned with the Anonymous movement before pivoting to ransomware operations in October 2023, officially launching a RaaS platform in June 2024 with an affiliate-friendly 88% revenue split, primarily targeting healthcare, financial services, and government sectors with over 250 documented victims as of late 2025. Killsec has listed 286 victims since February 2024.

Incident analysis

Sector context. Technology companies hold intellectual property, customer data, and source code — all highly valuable assets. A successful ransomware attack can also put downstream customers at risk through supply chain exposure.

Killsec typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .
