Hackers used a platform to crack down on the official Twitter accounts of the Olympics and FC Barcelona to post a message that well-known Neymar player would return to the football team.
A hacking team called OurMine, which last month breached the National Football Federation (NFL) social media accounts and 15 of its teams, hijacked Olympic and FC Barcelona accounts.

According to Engadget, Twitter confirmed the hacking, saying that OurMine used a "third-party platform" to gain control of accounts. Twitter closed the affected accounts and "worked closely" with partners to restore them. The International Olympic Committee said it was "investigating a possible breach" while Barcelona said it would conduct an audit of situation.
Ourmine is believed to be based in Saudi Arabia and violated the social media accounts of the NFL, 49ers, Cardinals, Bears, Bills, Broncos, Browns, Bucs, Cowboys, Colts, Chiefs, Eagles, Giants, Packers, Texans and Vikings last month. Most of them tweets posted by OurMine hackers came from Khoros - a web service used by digital marketing and PR for managing accounts SOCIAL MEDIA and linked to a social media account as a third-party application.

Ourmine has been involved in high profile hacking on past, including invading celebrity social media accounts such as Facebook's CEO Mark Zuckerberg, the CEO of Twitter Jack Dorsey and Google CEO Sundar Pichai, to name a few. The team has been active since 2016 and is believed to consist of several Saudis.
