Christian Slater returns to the role of the super-creepy "Wolf" in the latest film by HP warning users on cyber security -- and this time he's even more evil.

The new film sees him masterminding a cyber attack on a healthcare network (topical, following the ransomware attack on the U.K's National Heath Service last month). First he jumps on an unattended computer and manages to incapitate the chief information officer by changing his own medication, wiping his records and changing his name tag, to make sure he's not available when the main shutdown happens.

The seven-minute film details how computers and printers can put your company at risk, even if you think your network is secure. It ends with another warning from Slater: "To those of you in the hallowed seats of power in government, know this: you're next."

The spot was once again created out of Giant Spon and directed by Park Pictures' Lance Acord.
