In retaliation for the arrests, several members of the hacking collective appear to have launched distributed denial of service (DDoS) attacks against the Interpol Website, according to a Twitter account associated with the group, AnonOps. The site was intermittently available after Interpol's announcement.
"interpol.int seems to be #TangoDown. We can't say that this surprises us much," Anonymous IRC posted on Twitter shortly afterward.
There have been a number of arrests of individuals accused of participating in Anonymous-led DDoS attacks and other Web attacks over the past 12 months. The attacks are almost always followed by some form of a revenge attack by the collective's members, and there have been no noticeable impact on the group's recruitment efforts or reduction in their activities.
Anonymous has targeted police and other law enforcement organizations in recent weeks by launching DDoS attacks and breaching Websites. The Los Angeles Police Canine Association's Website was attacked Feb. 23. Previous victims include Websites of the Central Intelligence Agency and the FBI, as well as police departments in Boston, Arizona and Alabama.
