Stacheldraht
Stacheldraht (German for "barbed wire") is malware which performs a distributed denial-of-service (DDoS) attack.
It runs on Linux and Solaris.
It detects and automatically enables source address forgery.
It was written by "random", of the Austrian hacker group TESO.

Stacheldraht uses a number of different denial-of-service (DoS) attacks, including ICMP flood, UDP flood, TCP SYN flood, and Smurf attack.

It combines features of Trinoo and of Tribe Flood Network, and adds encryption.

Stacheldraht was later superseded by Blitzkrieg.
Blitzkrieg was maintained by "random" and by a loose group of associates.
