Majinahanashi listed cybersecurity firm CDA on its dark web leak site on 10 October 2026.
Majinahanashi has listed 22 victims since June 2026.
CDA was listed by Majinahanashi ransomware, a group with 42 victims recorded in this database. The listing appeared on the group's leak site on October 10, 2026.
Majinahanashi 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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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.
Yes. CDA was listed as a victim of the Majinahanashi ransomware group on October 10, 2026. The disclosure appeared on the group's dark web leak site.
CDA was attacked by Majinahanashi ransomware. Majinahanashi is one of the most active ransomware groups, having claimed 42 victims globally. The group typically employs a double-extortion model: encrypting the victim's files and threatening to publish stolen data.
The ransomware attack on CDA was disclosed on October 10, 2026. This date reflects when the victim was published on the threat group's leak site, which may differ from the actual date of initial compromise.
The specific data stolen from CDA has not been independently verified by this platform. Ransomware groups typically exfiltrate data before encrypting systems and use the threat of publication to pressure victims. Sensitive business data was likely targeted.
To defend against Majinahanashi and similar threat actors, organisations should: maintain regular offline backups tested for restoration; implement network segmentation to limit lateral movement; deploy multi-factor authentication on all remote access; use endpoint detection and response (EDR) tools; conduct regular phishing and security awareness training; and monitor threat intelligence feeds for indicators of compromise (IOCs) associated with active groups.
