A lot of time can be wasted performing trivial tasks over and over again, and it's especially true when it comes to hacking and penetration testing. Trying different shells to own a target, and testing out privilege escalation commands afterward, can eat up a lot of time. Fort ...more
Post-exploitation information gathering can be a long and drawn-out process, but it is an essential step when trying to pivot or establish advanced persistence. Every hacker should know how to enumerate a target manually, but sometimes it is worth it to automate the process. M ...more
SMB (Server Message Block) is a protocol that allows resources on the same network to share files, browse the network, and print over the network. It was initially used on Windows, but Unix systems can use SMB through Samba. Today, we will be using a tool called Enum4linux to ...more
