Update your iPhones and iPads
From The Register
“Apple has pushed out an emergency security update for iPhones, iPads and iPods after super sophisticated spyware was found exploiting three iOS vulnerabilities.
The iOS 9.3.5 upgrade plugs three holes that, according to researchers, are being used right now by the Pegasus surveillance kit – a powerful commercial malware package sold to governments for snooping on dissidents and journalists.
Pegasus exploits the bugs to inject itself into iThings. A victim simply has to click on a bad web link to start an infection. Once installed, Pegasus can read messages and emails, listen to calls, monitor social network posts, pull out Wi-Fi passwords, and so on. It essentially has comprehensive access to a poisoned handheld.”
