BillGates


BillGates is a modularized malware, of supposedly Chinese origin. Its main functionality is to perform DDoS attacks, with support for DNS amplification. Often, BillGates is delivered with one or many backdoor modules.

BillGates is available for *nix-based systems as well as for Windows.

On Windows, the (Bill)Gates installer typically contains the various modules as linked resources.
