OPSEC Mistakes

OPSEC (Operational Security) is the practice of protecting information and behavior that could identify you. The strongest tools fail when human habits leak the truth.

History is full of skilled operators caught not by broken crypto, but by a single careless mistake. This lesson studies those mistakes so you can avoid them in authorized work.

The classic error is linking your anonymous persona to your real one. Examples:

• Logging into a personal email or social account while on Tor.
• Reusing a username across anonymous and real accounts.
• Accessing a personal site and a covert one from the same session.

One overlap and an investigator connects the dots permanently.
