Incident Analysis

NK Customer Solutions was targeted by Blacklock ransomware, one of the most active ransomware groups in our database with 64 confirmed victims globally. The attack was disclosed on June 29, 2025, when NK Customer Solutions appeared on the group's dark web leak site.

NK Customer Solutions is based in India , operating in the Business Services sector. India ranks #8 globally for ransomware attacks, with 412 victims in our database.

Sector context: Business services firms often have access to multiple client environments, making them high-value pivot points for ransomware operators seeking to maximise impact across multiple victim organisations.

Blacklock 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 โ€” 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.
