Dahjr’ PGP compromised
The BTC hack happened on New Year’s eve. Dashjr posted on his official Twitter account noting that hackers illegally obtained his PGP key. PGP is a common security procedure that uses the public key system in which every individual user has a unique encryption key known publicly along with a private key only known by the user.
