Apple this week patched a bug in the iOS version of Safari that had been used by criminals to spook users into paying $125 or more because they assumed the browser was broken.
The flaw, fixed in Monday’s iOS 10.3 update, had been reported to Apple a month ago by researchers at San Francisco-based mobile security firm Lookout.
“One of our users alerted us to this campaign, and said he had lost control of Safari on his iPhone,” Andrew Blaich, a Lookout security researcher, said in a Tuesday interview. “He said, ‘I can’t use my browser anymore.'”
that claims a computer is heavily infected with malware. Such software nags users with pervasive pop-ups and fake alerts until they fork over the “registration” fee, sometimes in the hundreds of dollars.
