via HACKADAY: This Week in Security: What’s up with Whatsapp, Windows XP Patches, And Cisco is Attacked by the Thrangrycat

Whatsapp allows for end-to-end encrypted messaging, secure VoIP calls, and until this week, malware installation when receiving a call. A maliciously crafted SRTCP connection can trigger a buffer overflow, and execute code on the target device. The vulnerability was apparently found first by a surveillance company, The NSO Group. NSO is known for Pegasus, a commercial spyware program that they’ve marketed to governments and intelligence agencies, and which has been implicated in a number of human rights violations and even the assassination of Jamal Khashoggi. It seems that this Whatsapp vulnerability was one of the infection vectors used by the Pegasus program. After independently discovering the flaw, Facebook pushed a fixed client on Monday.
