Checko.ru

Checko is a prominent Russian service used for verifying business entities and legal records. In 2024, the platform was targeted by extensive web scraping operations that resulted in the extraction of approximately one million records. The incident involved automated scripts gathering data from public business profiles. The harvested information includes high level details on company directors, founders, and legal structures. While the data is largely based on public registrations, the organized compilation of emails and phone numbers linked to specific business leaders increases the risk of targeted phishing and social engineering attacks against the Russian corporate sector.
