Incident Analysis

CSIKBS was targeted by Helldown ransomware, one of the most active ransomware groups in our database with 36 confirmed victims globally. The attack was disclosed on November 6, 2024, when CSIKBS appeared on the group's dark web leak site.

CSIKBS is based in Japan , operating in the Consumer Services sector. Japan ranks #11 globally for ransomware attacks, with 251 victims in our database.

Sector context: Organisations in this sector hold valuable data and operational systems that ransomware groups seek to exploit for financial gain through encryption and data exfiltration.

Helldown 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 โ€” 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.
