About the J group

J is an emerging ransomware group that launched its leak site in May 2025, claiming over 41 victims by late 2025 including FAI Aviation Group (Germany), operating primarily as a leak-site-centric extortion identity with limited public technical analysis. J has listed 41 victims since February 2025.

Incident Analysis

daycohost.com was targeted by J ransomware, one of the most active ransomware groups in our database with 41 confirmed victims globally. The attack was disclosed on June 1, 2025, when daycohost.com appeared on the group's dark web leak site.

daycohost.com is based in VE , operating in the Technology sector. VE ranks #50 globally for ransomware attacks, with 29 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.

J 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. Last data update: Sep 7, 2026 04:00 UTC.
