The wi-fi connections of businesses and homes around the world are at risk, according to researchers who have revealed a major flaw dubbed Krack. It concerns an authentication system which is widely used to secure wireless connections. Experts said it could leave "the majority" of connections at risk until they are patched. The researchers added the attack method was "exceptionally devastating" for Android 6.0 or above and LinuxPresumably (if it's for real), the www & banking industries are in utter shock, as well they might be. As well might we all. As usual, the bigger the issue the less attention it gets...
A sounds like a pretty thoroughgoing *patch* will be required. A massive kick in the nuts for a priori reasoning about what's "mathematically proven" to be secure. Safely encrypted? In the real world, there's always a flaw! No limits to human ingenuity - "what one man can invent, another can discover" (S.Holmes, 1903).
It's worth taking a look at the lucid write-up** by Mathy Vanhoef, the bright Belgian who discovered the mighty cockup. That is one articulate geek! Beautiful prose on a complex topic in what, presumably, is not his mother tongue. The whole thing reads like the remarkable Enigma exploits of Turing, Tutte et al at Bletchley Park.
If only all technical issues had such excellent advocates, eh? (Bit of a coincidence, the timing of that cartoon).
** in the original version of this post I linked to Vanhoef's 'KrackAttack' website. Subsequently, McAfee has started warning about that site! Who knows what to think?! But I've removed the link. There are plenty of places around the www where you can read Vanhoef's fine prose.
