S-04Data Exfiltration

/security/data-exfiltration

Secrets that legitimately entered context leave through any outbound channel — URLs, headers, rendered images, commit messages.

Key insight

Exfiltration needs two things: a secret in context and an outbound channel. You rarely control the first; you fully control the second. Enumerate every way bytes leave.

Failure mode

Blocking the obvious channel (email) while markdown image URLs, DNS lookups and log lines remain wide open.
