stackfhex is a simple program to automate the task of converting strings/data into 4-byte push statements. This simplifies what is normally a tedious task in x86 shellcode development, reversing the string for little-endian'ness, and then padding the data as necessary, outputting in ready-to-go assembly push expressions.

silentdoor is a proof-of-concept connectionless, PCAP-based backdoor for linux that uses packet sniffing to bypass netfilter. It sniffs for UDP packets on port 53, runs each packet against a decryption scheme, if the packet validates than it runs a command.

macspoof is a tool for spoofing a network interface's MAC address in Linux. It lists 7500+ available MAC prefixes, the ability to search and sort by company name or MAC prefix, and an option to pick from the results at random. It then sets the interface's MAC address accordingly.
