wpwrakDocScrutinizer05: nice article on hacking BMWs. and look at who wrote it :) http://www.heise.de/ct/ausgabe/2015-5-Sicherheitsluecken-bei-BMWs-ConnectedDrive-2536384.html15:02
DocScrutinizer05ROTFL MUUHAAAHHAAAAHAA   >>freundlicherweise erwies sich die Combox als sehr kooperativ: Wenn sie eine ansonsten gültige NGTP-SMS erhielt, in der lediglich die VIN falsch war, so antwortete sie mit einer Fehler-SMS, ebenfalls im NGTP-Format. Die enthielt als Absender die korrekte VIN des Fahrzeugs.<<15:21
DocScrutinizer05only question: where from a hacker gets the IMSI/phone-number?15:22
DocScrutinizer05no problem for near field, but hey, we want to rule whole highways, right?15:23
wpwrakhehe :)15:23
wpwrakalready like this it's pretty bad15:23
DocScrutinizer05we want to shoot down cars at other end of the country by simply DNS-poisoning a few servers and using the regular internet and phone network15:24
wpwraki wonder, when he visited bmw, whether they counted the cars they had on site after he left. just to be sure :)15:27
DocScrutinizer05haha15:36
DocScrutinizer05:-P15:36
DocScrutinizer05I wonder what else is possible except the rather boring unlocking of doors15:37
DocScrutinizer05"tune" the engine controller? 30° early ignition15:37
DocScrutinizer05breaks? steering?15:37
DocScrutinizer05gear?15:38
DocScrutinizer05prolly ASP is most "funny" - 'please break 100% on both rear wheels only"15:39
wpwraknaw, the left wheels only :)15:39
DocScrutinizer05or that15:39
DocScrutinizer05though I guess a car is amazingly stable and steerable as long as one "line" of wheels stil has full contact to road15:40
DocScrutinizer05sure it will tend to the left, but you can compensate easily with steering15:41
DocScrutinizer05maybe not much worse that strong side winds15:41
DocScrutinizer05than*15:41
DocScrutinizer05fullblock of both read wheels though, and then a gentle 5% break on only one of both front wheels15:42
DocScrutinizer05s/read/rear/15:42
wpwraki'd count on the element of surprise to cause most of the damage. "controllable" doesn't mean that a driver will :)15:44
DocScrutinizer05you ever tried full stop on bike with only read wheel?15:44
DocScrutinizer05you'll inevitably see own rear wheel pss you on either left or right side15:45
DocScrutinizer05you also know how ralley drivers driver turns? hand break to block reag wheels15:46
DocScrutinizer05rear*15:46
wpwrakon the other hand, there are plenty of accidents with car and road in perfect condition, nice weather, good sight, no other traffic nearby, yet ... boom15:53
DocScrutinizer05https://www.youtube.com/watch?v=3VHXwlJtNgU  watch rear wheels!15:53
wpwrakif you want to explore the full extent of human frailty, i'd recommend avherald. that's all trained professionals, be it pilots, atc, mechanics, etc., subject to strict controls and regulations. yet a good number of incidents / accidents are just "human error"15:55
wpwrakyou may want to check the videos before you recommend watching them ;-))15:57

wpwrakyeah, i don't like it when my cars do that. you can't complain about the braking efficiency, though :)16:01
wpwrakyeah, 02:00 looks more familiar :)16:02

DocScrutinizer05http://en.wikipedia.org/wiki/Handbrake_turn16:08
DocScrutinizer05the higher the cruising speed the better it works16:09
DocScrutinizer05and when you even could break only one of both front wheels too... simply awesome16:10
wpwrakthe the more spectacular the failure when something goes wrong :)16:10
wpwrakyou could hack into your ABS ;-)16:11
DocScrutinizer05you can bet on _something_ "going wrong" when you do this via remote control16:11
DocScrutinizer05ASP >> ABS16:11
DocScrutinizer05well, maybe control over ASP is not _that_ simple even on BMW16:12
DocScrutinizer05I don't know of any data buses those ASP/ABS controlers expose to rest of system16:12
DocScrutinizer05for good reason those are autonomous and sealed16:13
DocScrutinizer05at least they were, a 10 or 20 years ago16:13
DocScrutinizer05nowadays though... who knows. Designers might want to show APS-intercet per wheel in headup display, needs a data bus from ASP controller to somewhere else. That's it then16:15
DocScrutinizer05I rejected ~ 15 job offers in automotive industry during last 8 years16:16
wpwraknowadays they're probably cloud-based, with monthly subscriptions - BaaS, braking as a service ;-))16:18
