Incident Analysis

kyb.com was targeted by Cactus ransomware, one of the most active ransomware groups in our database with 157 confirmed victims globally. The attack was disclosed on March 17, 2025, when kyb.com appeared on the group's dark web leak site.

kyb.com is based in Japan , operating in the Technology sector. Japan ranks #11 globally for ransomware attacks, with 229 victims in our database.

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

Cactus 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 β€” 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.
