OopSec

Paul Manifort recently pled guilty to witness tampering after contacting potential witnesses then denying it. He thought he was being clever by using WhatsApp to encrypt his phone calls and texts. Unfortunately Manifort backed up his chat logs in plaintext to Apple iCloud, so the FBI just subpoenaed Apple for the chat logs. Simple.

Operational Security (OpSec) is a mindset not an app you can download. If the person with whom you’re chatting is uploading your chat logs to the cloud1 the entire communications chain is compromised. Likewise if they take screenshots of the chats or if they’re informants.

The only safe place to keep damaging letters is in the fireplace, between burning logs.
