About the Lockbit5 group

LockBit 5.0 ("ChuongDong") emerged in September 2025 as the group's resurgence following the February 2024 law enforcement takedown, introducing cross-platform payloads targeting Windows, Linux, and VMware ESXi with enhanced evasion capabilities and continuing the RaaS affiliate model of its predecessors. Lockbit5 has listed 374 victims since April 2023.

Incident analysis

tnmed.org was listed by Lockbit5 ransomware, a group with 401 victims recorded in this database. The listing appeared on the group's leak site on August 28, 2026.

tnmed.org is based in Tunisia and operates in the Healthcare sector. Tunisia ranks #58 worldwide for ransomware disclosures, with 24 victims in this 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.

Lockbit5 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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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 .
