About the Funksec group

FunkSec is an AI-assisted ransomware-as-a-service group that launched its data leak site in December 2024 and rapidly claimed over 85 victims across government, technology, finance, and education sectors globally, demanding unusually low ransoms and using AI tooling to lower the technical bar for affiliates. Funksec has listed 172 victims since April 2023.

Incident Analysis

fuse.io was targeted by Funksec ransomware, one of the most active ransomware groups in our database with 172 confirmed victims globally. The attack was disclosed on December 13, 2024, when fuse.io appeared on the group's dark web leak site.

fuse.io is based in Israel , operating in the Technology sector. Israel ranks #20 globally for ransomware attacks, with 141 victims in our database.

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.

Funksec typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data.
