INCIDENT: Britain’s Ad Agency WPP Hit by a Cyberattack

Britain’s WPP, the world’s biggest advertising agency, said on Tuesday it had been hit by a cyber attack. WPP Plc’s Chief Executive Officer Martin Sorrell, at a Bloomberg event in Davos half a year later stated: "WPP shut down all its systems when it was hacked and communicated internally on an hourly basis", Sorrell said. Several weeks before WPP has hacked, a WannaCry ransomware attack infected more than 300,000 computers across 150 countries. Microsoft Corp. and others responded quickly by providing software updates, including to WPP, but to no avail, Sorrell said. “Those patches couldn’t stop the malware attack that we had in June".
