WhatsApp finds spyware that infects with a call alone

The Associated Press NEW YORK (AP) — Spyware crafted by an “advanced cyber actor” infected multiple targeted mobile phones through the popular WhatsApp communications program without any user intervention through in-app voice calls, the company said.

The Financial Times identified the actor as Israel’s NSO Group, and a WhatsApp spokesman later said “we’re certainly not refuting any of the coverage you’ve seen.”

The malware was able to penetrate phones through missed calls alone via the app’s voice calling function, the spokesman for the Facebook subsidiary said late Monday. An unknown number of people — an amount in the dozens at least would not be inaccurate — were infected with the malware, which the company said it discovered in early May, said the spokesman.

John Scott-Railton, a researcher with the internet watchdog Citizen Lab, called the hack a very scary vulnerability. “There’s nothing a user could have done here, short of not having the app,” he said.

The WhatsApp spokesman said the attack had “all the hallmarks of a private company that has been known to work with governments to deliver spyware that has the ability to take over mobile phone operating systems.”

The spokesman said WhatsApp, which has more than 1.5 billion users, immediately contacted Citizen Lab and human rights groups, quickly fixed the issue and pushed out a patch.

He said the flaw was discovered while “our team was putting some additional security enhancements to our voice calls” and that engineers found that people targeted for infection “might get one or two calls from a number that is not familiar to them. In the process of calling, this code gets shipped.”Speech
