Listed by Monti on
Compiled from this incident record and the threat intelligence profile for Monti. Figures and technique mappings are quoted from the source data, not inferred.
Monti is a ransomware group first observed in June 2022 that initially copied nearly all of Conti's leaked source code, pivoting to target government, legal, and healthcare entities, later releasing a new Linux variant in 2023 with significantly less Conti code similarity, and experimenting with an affiliate model. Monti has listed 110 victims since December 2022.
Phoenix was listed by Monti ransomware, a group with 63 victims recorded in this database. The listing appeared on the group's leak site on March 4, 2025.
Monti 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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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. Phoenix was listed as a victim of the Monti ransomware group on March 4, 2025. The disclosure appeared on the group's dark web leak site.
Phoenix was attacked by Monti ransomware. Monti is one of the most active ransomware groups, having claimed 63 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 Phoenix was disclosed on March 4, 2025. 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 Phoenix 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 Monti 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.
