DarkWeb Monitor

Dark Monitor is a privacy-preserving data breach and credential exposure monitoring service operated by PWN-ALL. It enables users to check whether a personal email address has appeared in recent third-party data breaches, dark-web datasets, credential dumps, or infostealer malware logs.

The service is designed to minimize the exposure of user data during the verification process. Email addresses are cryptographically blinded in the user's browser using an Oblivious Pseudorandom Function (OPRF) before any request is processed by the server. The server therefore performs the lookup without receiving the email address in readable form. Email addresses and IP addresses are not stored in plaintext.

Dark Monitor maintains a continuously updated breach index and uses a rolling 12-month data window to focus results on recent and actionable exposure risks while reducing unnecessary retention of historical breach data.

The service helps users identify compromised credentials early and take appropriate security actions, such as changing exposed passwords and strengthening account security.
