Silencer holds three different functionalities. It will deploy a backdoor in a listening service that an attacker must connect to, feed the magic word, and then portscan the machine to find the bindshell spawned, it has an Apache backdoor that allows a connection over HTTP to drop to a shell, and it also has a read sniffer built in that goes through the kernel read() process and then logs it to /tmp/.es.rox. The authors ask to be contacted if anyone finds any systems or kernels that this does not work on.
