Remote administration kernel module designed for the 2.4 series. It replaces system calls by inserting a push ret at the beginning of system_call, making the program jump to specified code. It provides a remote terminal backdoor through SYS_read hooking which means you can enter the box through any open tcp port. The connection is XOR encrypted and the module hides ports and pids. It also hides itself from vmalloc structure scanning and lsmod. Tested on Redhat 7.2 and 8.0. Currently lacks SMP support and is not considered stable so please exercise caution when utilizing this.
