Stagefright exploit reliably assaults Android telephones
You might know that the Stagefright safety flaw is theoretically harmful, however it hasn’t been that dangerous in apply — it is simply too troublesome to implement on an Android gadget in a dependable means. Or somewhat, it was. Safety researchers at NorthBit have developed a proof-of-idea Stagefright exploit, Metaphor, that reliably compromises Android telephones. The secret is a again-and-forth process that gauges a tool’s defenses earlier than diving in. Go to an internet site with a maliciously-designed MPEG-four video and the assault will crash Android’s media server, ship hardware knowledge again to the attacker, ship one other video file, acquire further safety knowledge and ship one final video file that really infects the gadget.
It sounds laborious, however it works shortly: a typical assault breaks right into a telephone inside 20 seconds. And whereas it is only on a Nexus 5 with inventory firmware, it is recognized to work on the custom-made Android variants discovered on telephones just like the HTC One, LG G3 and Samsung Galaxy S5.
