Threat Score
Security audits found approximately 3.3 million POP3/IMAP hosts operating without TLS, exposing user credentials sent over default ports (110 for POP3, 143 for IMAP) in plaintext; the report urges disabling unencrypted ports, migrating to encrypted ports (995/993), implementing stronger authentication (OAuth2, 2FA), and monitoring/restricting access to mitigate credential interception and MITM risks.
