Believed to be a Saudi Arabian hacking group, "OurMine" tweeted: "Hi FC Barcelona, it's "OurMine" (Security Group), please contact us.and sorry for the hoax".
Barcelona is in pursuit of Liverpool's Phillipe Coutinho and Borussia Dortmund's Ousmane Dembele to replace Neymar and has also signed Paulinho from Asian club Guangzhou. Neymar debuted for PSG in a match with Toulouse the past weekend.
It is the second time the Catalan club's social media channels have been hacked after activists claiming to be the Syrian Electronic Army managed to post a series of tweets in 2014. It basically is a security company that looks for vulnerabilities in websites of big organizations and social media accounts of their CEOs etc.
