Incident analysis

Fidex was listed by Deadlock ransomware, a group with 117 victims recorded in this database. The listing appeared on the group's leak site on November 8, 2026.

Fidex is based in Mexico. Mexico ranks #11 worldwide for ransomware disclosures, with 309 victims in this database.

Deadlock 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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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.

To defend against Deadlock 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.
