November 2020 – Discovery and Disclosure
Comparitech responsibly disclosed the breach to Nitro on November 16, 2020. Within 24 hours, Nitro secured the database. However, the window of exposure remains unknown. The database had been indexed by search engines like Shodan, meaning any malicious actor could have downloaded the entire dataset between October and November.
- User Databases: The exfiltrated data included user PII (Personally Identifiable Information), such as names, email addresses, and hashed passwords. While the passwords were hashed (obscured), the quality of the hashing algorithm determines the ease with which attackers can crack them offline.

- Source Code: The attackers also exfiltrated proprietary source code for Nitro’s software, posing a risk for future zero-day exploits if vulnerabilities were found in the code.
