About the Funksec group

FunkSec is an AI-assisted ransomware-as-a-service group that launched its data leak site in December 2024 and rapidly claimed over 85 victims across government, technology, finance, and education sectors globally, demanding unusually low ransoms and using AI tooling to lower the technical bar for affiliates. Funksec has listed 172 victims since April 2023.

Incident analysis

ctsjo.com was listed by Funksec ransomware, a group with 172 victims recorded in this database. The listing appeared on the group's leak site on December 5, 2024.

ctsjo.com is based in Costa Rica and operates in the Transportation/Logistics sector. Costa Rica ranks #64 worldwide for ransomware disclosures, with 21 victims in this database.

Sector context. Logistics companies are targeted because supply chain disruption has cascading effects on customers and partners, amplifying pressure to pay ransoms quickly to restore operations.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .

How can organisations protect against Funksec attacks?

To defend against Funksec 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.
