Incident Analysis

Tan Chong Motor Holdings Berhad was targeted by Crypto24 ransomware, one of the most active ransomware groups in our database with 46 confirmed victims globally. The attack was disclosed on July 16, 2025, when Tan Chong Motor Holdings Berhad appeared on the group's dark web leak site.

Tan Chong Motor Holdings Berhad is based in Malaysia , operating in the Manufacturing sector. Malaysia ranks #25 globally for ransomware attacks, with 117 victims in our database.

Sector context: Manufacturing companies are frequently targeted because production downtime directly translates to financial loss. Ransomware operators exploit this time-sensitivity to demand higher ransoms and faster payment.

Crypto24 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.
