Compromise the enterprise starting the security test with a regular end-user pc that is part of the Windows Domain. This includes Priv. scalation, HashDump and use of techniques like “pcexec” to gain acces to other network stations. Intermediate: Cryptography: I’ve take the Stanford Cryptography I course in which i’ve learned the difference between stream ciphers and block ciphers, PKI, Web Certificates, what constitute a secure PRG, among other cryptography basics, ciphers history and how to break them.
