Security readout for executives and security teams
Pegasus Mail 3.0 and earlier stored POP3 email passwords in pmail.ini using weak encryption. A person with local access to the affected computer or file could recover the password and read email. This is mainly a legacy endpoint and credential-exposure risk, not a confirmed remote compromise issue. Exposure is likely limited to systems still running Pegasus Mail 3.0 or earlier, especially shared Windows endpoints, old user profiles, backups, or file shares containing pmail.ini. Organizations without this legacy client are unlikely to be affected. Treat this as a targeted legacy cleanup and credential-protection issue. It is not shown as actively exploited, but exposed mailbox passwords can create privacy, legal discovery, and business email risks if old systems or backups remain accessible. Mitigation focus: Inventory endpoints and backups for Pegasus Mail 3.0 or earlier.; Check vendor guidance before assuming any specific patched version.; Restrict local access to pmail.ini and affected user profile data..
