Откриха уязвимост засягаща голяма част от процесорите на Intel

Интересно е да отбележим, че някои организации като Electronic Frontier Foundation (EFF) предупреждаваха за рисковете

Едва ли много потребители са запознати с подсистемата Intel Management Engine (IME), но тя играе важна роля в Intel базираните системи. От 2008 насам, почти всеки процесор на компанията идва с IME, а целта на тази функционалност е да контролира централния процесор и други хардуерни компоненти, както и да изпълнява отдалечени администраторски задачи. Интересно е да отбележим, че някои организации като Electronic Frontier Foundation (EFF) предупреждаваха за рисковете, които носи подобна подсистема. Тя може да контролира компютърната система дори когато машината е изключена. Сега тези предупреждения изглежда се оправдават, съобщава TechSpot. 

Positive Technologies, компания занимаваща се с изследвания в сферата на сигурността, е открила пропуск в защитата на тази система. Специалисти на компанията могат да изпълнят неподписан код на почти всеки компютър работещ с IME през USB. Атаката работи чрез експлоатиране на JTAG дебъг портове, които са вградени в компютъра. Учените са открили начин да заобиколят съществуващите бариери и да изпълнят код от USB памет. Това не е първата уязвимост открита в IME, но е най-лесно изпълнимата. Очаква се Intel да реагира бързо и да закърпи уязвимостта. 

 

Game over! We (I and @_markel___ ) have obtained fully functional JTAG for Intel CSME via USB DCI. #intelme #jtag #inteldci pic.twitter.com/cRPuO8J0oG
