[QUOTE="hjlbx, post: 519104"] Anti-Executables are not generally susceptible to RATs. That isn't what she demonstrated in her video. She demonstrated in this particular video that AppGuard is susceptible to a specific type of bypass - a Trusted Publisher "certificate" bypass - when run using AppGuard's default Protected mode. That type of vulnerability has been a "known issue" for a long time now - but she is the only one who has demonstrated it via a video. To overcome this Protected mode vulnerability, BRN included Lock Down mode. She could have used the same certificate, added the publisher to the Trusted Publisher list of NVT ERP, NVT SOB, [S]VooDooShield[/S], SecureAPlus and I believe Faronics - and demonstrated the same thing with each of them. [COLOR=#ff0000][B]EDIT: Voodooshield does not allow files solely by digital signature alone; there is no Trusted Publisher list in Voodooshield.[/B][/COLOR] Remove that Trusted Publisher from the list, and the security soft behavior changes completely; either the file will be blocked or allowed - but allowed only with limited rights. Which behavior - blocking or allowing - depends upon the anti-executable and settings. The greater point that she makes is that reliance upon digital certificates as a basis for judging a file as safe or unsafe can get you infected... [/QUOTE]
