To find an unlocked car it is often enough to test several doors of cars parked in a car park. Cybercriminals take a similar approach by indiscriminately sending a program strings of letters, figures and special characters, hoping to find a security loophole. To pre-empt these activities, computer scientists at the CISPA Helmholtz Centre (i.G.), are developing software that does this more efficiently. Within minutes the software learns the input format and produces millions of valid program entries, automatically extracting the necessary knowledge from the programs. The researchers are presenting their latest tools at the CEBIT computer expo from 11 Ewhk vf Iqtlyfc, pbgoh K32 rm mvkh 84.
