Klys is a worm with backdoor characteristics that opens several IRC ports, allowing remote access to the affected computer, and drops the worm Cult on the system.
Additionally, if the affected computer is connected to a network, Klys unshares most shared resources, admin$ and print$ among others, so that the applications that need these resources will stop working.
Klys spreads via the chat program IRC and across shared networks.
Klys is difficult to recognize, as it does not display any messages or warnings that indicate that it has reached the computer.
