Opsec (Operations security) is a process that identifies, analyzes, and protects sensitive or critical information to prevent adversaries, bad guys or competitors from exploiting it. Otherwise, it makes fun of people who fail to protect private details online, or who overreact about tiny secrets while leaking major ones.

bad opsec 

A hacker's failure to practice operational security (OPSEC), leading to exposure of personally identifying information. Common mistakes include using personal information in emails that you use for black hat activity, leaving financial paper trails, not hiding your IP address properly through services like TOR and Tails, not using encryption technology such as cryptocurrency and PGP encryption -- and most importantly, failure to shut the fuck up.

Typical outcomes for a cybercriminal practicing bad opsec include getting doxed, extorted, ratted on, or worse, arrested and indicted by the federal police.
