IMAP exploitation turns enumeration findings into mailbox access. Credential brute-forcing is the most common attack vector, especially when the server lacks account lockout policies and allows plaintext authentication.

Plaintext credential interception targets IMAP connections without TLS. When STARTTLS is optional or absent, credentials and email content travel in cleartext and can be captured via network sniffing or man-in-the-middle positioning.

Once authenticated, full mailbox access lets you read emails, extract attachments, and harvest credentials from password reset messages and internal communications.
