Incident Analysis

CLEARSYNTH LABS LIMITED was targeted by Blacknevas ransomware, one of the most active ransomware groups in our database with 45 confirmed victims globally. The attack was disclosed on August 6, 2025, when CLEARSYNTH LABS LIMITED appeared on the group's dark web leak site.

CLEARSYNTH LABS LIMITED is based in India , operating in the Manufacturing sector. India ranks #8 globally for ransomware attacks, with 446 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.

Blacknevas 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.
