Federal authorities have accused two men of hacking the email and social media accounts of multiple athletes with the National Football League and the National Basketball Association and either selling or ransoming the credentials for profit. In one case, according to a criminal complaint unsealed on Wednesday, the account compromises resulted in explicit photos of one of the NFL players being posted to his Twitter and Instagram accounts. Accounts he followed were blocked, most likely in an attempt to delay Moss from learning of the postings. More explicit videos and images appeared later but were subsequently removed within about 30 minutes.
