Members of the UK Computer Crime Unit have arrested a suspected member of the notorious hacker group Fluffi Bunni.
Lynn Htun, 24, was arrested by the Metropolitan Police when they recognised him on a stand at the InfoSec computer security show in Olympia.
Htun was arrested on charges of non-appearance in Guildford Crown Court on forgery charges, said police spokesman Nick Jordan.
He was due to appear in Guildford Crown Court yesterday morning, Jordan said.
Fluffi Bunni is believed to be responsible for a series of attacks against the websites of US computer security organisations. After compromising sites, the group left a picture of a stuffed pink rabbit as its calling card.
Fluffi Bunni carried out 23 attacks between June 2000 and January 2002, according to digital security company Mi2g. These included attacks on www.mcdonalds.co.uk in February 2001, www.sans.org and www.attrition.org in July 2001 and www.securityfocus.com in November 2001.
The Metropolitan Police stressed that the arrest was purely on non-appearance charges and did not say how its computer crime unit officers recognised Htun.
Htun, who used the online name "Danny-Boy", was known within hacking circles as a member of Fluffi Bunni, according to Rafael Núñez, a senior research scientist at Scientech de Venezuela in Caracas.
However, the group had a "fluid" membership and included other prominent hackers outside the UK as well, he said.
Htun may have initially come to the attention of UK authorities monitoring Internet Relay Chat channels frequented by hackers. He had a reputation as a "packet monkey", someone responsible for conducting so-called "denial-of-service" attacks against websites, Núñez said.
