AKILL: Bustin' The Botnet Brain
Jane Phare and Carolyne Meng-Yee write in The New Zealand Herald:
When Owen Walker was 16 he began to develop a highly sophisticated system to infiltrate computers and effectively control them without anyone knowing.More here.
For two years, between January 2006 and November 2007, he controlled tens of thousands of computers through servers outside New Zealand either by leasing space or by accessing them illegally using software he had developed himself.
The exact number of computers he infected may never be known. Known by his online ID AKILL (a name taken from the "automatic kill" command used to knock unwanted participants off chat channels), Walker is said to have led a small, elite group of computer programmers who used malware to infect and remotely control computers, using them as robots - or bots.
Walker created his own bot code, considered by investigators to be among the most advanced bot programming encountered.
