It had been a trying 24 hours for the Blaugrana, as on Tuesday the club announced they were suing Neymar after alleging the Brazilian failed to fulfill his agreement with the team.
And things only got worse later as the club's official Twitter account sent out a tweet saying, "Welcome Angel Di Maria to FC Barcelona!"
Over the course of the next hour, the tweets would disappear and reappear on Barcelona's timeline, as a back-and-forth battle between the hackers and the club ensued.
Later, the club tweeted: "Our accounts have been hacked tonight. We're working to solve the problem as soon as possible.
"Thanks for your patience."
