Who is Atlas - Piers Morgan's Twitter Hacker
Atlas is known in multiple forums online such as OGUsers & BreachForums for his SIM Swapping abilities. It is believed that Atlas used the same technique to compromise Piers Morgan's Twitter account by social engineering the carrier of Piers Morgan.
Piers Morgan has regained access to his Twitter account with all of the tweets removed.
It is believed that once Piers Morgan's email was leaked in a 'sample' on BreachForums - 2 Slick (Alias: Atlas, BitcoinBandit, Tea) was able to discover the carrier which Piers Morgan used.
Attempting to reset a password with BT Email - it shows a few digits of the start of the phone number and a few at the end - with parts censored.
However - the start of the phone number is unique to a carrier and therefore Atlas was able to discover the carrier Piers Morgan uses and then social engineered workers to then gain access to the sim.
Piers Morgan's email is no longer compromised and is back to a normal state - which indicates Pier's email and phone number were both compromised - which resulted in a total lockout and breach.
Atlas is a user on BreachForums and has been further given reputation on the website for selling a database - this does not look like the account the user is active on however.
