Summary : Timing attacks have been exploited in the wild for ages. In recent times timing attacks have largely been relegated to use only by cryptographers and cryptanalysts. In this presentation SensePost analysts will show that timing attacks are still very much alive and kicking on the Internet and fairly prevalent in web applications (if only we were looking for them). The talk will cover SensePost-aTime (our new SQL Injection tool that operates purely on timing differences to extract data from injectable sites behind draconian firewall rulesets), our new generic (timing aware) web brute-forcer and lots of new twists on old favorites. We will discuss the implications of timing on current JavaScript malware discussing XSRT (Cross Site Request Timing) (because we can never have too many acronyms!) and will demonstrate how reasonably effective this is against the "Same Origin Policy"
If you are doing testing today, and are not thinking a lot about timing, chances are you are missing attack vectors right beneath your stop-watch!
