Keith Richards, Tame Impala and Bon Iver had their Twitter accounts hacked this weekend

Meanwhile, Tenacious D's account falsely announced the death of Jack Black

Keith Richards, Tame Impala, Bon Iver and Tenacious D all had their Twitter accounts hacked over the weekend.

Bon Iver’s handle was changed to “@ihavelegcancer” and his account posted an inappropriate tweet about the late Muhammad Ali. Meanwhile, Tame Impala’s account sent out a bomb threat, posting: ‘I HAVE 15 C4’S IN MY BAG AND 12 PIPEBOMBS IN MY BAG ALSO” at the account of US airline Jet Blue.

Tenacious D’s account falsely announced the death of Jack Black, briefly sparking rumours that the band’s frontman and Hollywood actor had died. The account has since reassured fans that Black is alive and well.

The accounts of Bon Iver and Keith Richards also informed followers that they had been hacked. “Earlier today Keith’s Twitter account was hacked along with other verified accounts. The hateful tweets that were posted have been removed,” the Rolling Stones guitarist’s account posted.

Though the hacks are presumably in some way linked, it is currently unknown who is behind them. Last week Katy Perry also had her Twitter account hacked.

The singer’s account posted a series of abusive tweets to her followers before sharing a Soundcloud link to a new song called ‘Witness’ which it claimed, apparently falsely, had been recorded by Perry.
