ThreatAI Analysis

Compiled from this incident record and the threat intelligence profile for Killsec. Figures and technique mappings are quoted from the source data, not inferred.

About the Killsec group

KillSec originated as a hacktivist group aligned with the Anonymous movement before pivoting to ransomware operations in October 2023, officially launching a RaaS platform in June 2024 with an affiliate-friendly 88% revenue split, primarily targeting healthcare, financial services, and government sectors with over 250 documented victims as of late 2025. Killsec has listed 285 victims since February 2024.

Incident Analysis

LiquiTech was targeted by Killsec ransomware, one of the most active ransomware groups in our database with 286 confirmed victims globally. The attack was disclosed on November 20, 2024, when LiquiTech appeared on the group's dark web leak site.

LiquiTech is based in Colombia , operating in the Healthcare sector. Colombia ranks #25 globally for ransomware attacks, with 126 victims in our database.

Sector context: Healthcare organisations are high-value ransomware targets because patient data is extremely sensitive, regulatory penalties for breaches are severe, and operational downtime can threaten patient safety — all factors that increase ransom payment pressure.

Killsec 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.

How can organisations protect against Killsec attacks?

To defend against Killsec 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.
