People get Penetration tests and vulnerability assessments to find if they have vulnerabilities that would allow an attacker to access their network but often attackers are getting in ways that penetration testers are unable to test for. The purpose of this talk is to try to introduce and encourage a different kind of security test on a network, malware and backdoors. We plan to showing a demo on how to perform this type of test, give advice from our experiences reversing malware and demo our malware library we have created that could be used to perform these type of tests.
