This quarter, several Anonymous members or affiliates were the target of
law enforcement operations.

After the LulzSec member “Sabu” pleaded guilty in August 2011 and
cooperated with FBI, law enforcement agents caught other top members of
the computer hacking group. The suspects—who included two men from the
United Kingdom, two from Ireland, and two from the United States—were
indicted in the Southern District of New York.

Earlier in the quarter, Interpol announced the arrest of
25 suspected members of Anonymous in Argentina, Chile, Colombia, and Spain.

W0rmer and Kahuna, two members of CabinCr3w, a hacker group close to
Anonymous, were arrested on March 20 in the United States.

This quarter we saw that not only the police can disrupt cybercriminal
operations. In a January post, the famous researcher Dancho Danchev
exposed the identity and data he discovered about a Russian individual
linked to the gang behind Koobface.

Some days later, The New York Times disclosed four other names that a
group of security researchers had planned to announce.

We close with Microsoft’s Operation B71, which focused on botnets using
Zeus, SpyEye, and Ice-IX variants. On March 23, Microsoft unveiled a
joint lawsuit with the Financial Services Information Sharing and
Analysis Center (FS-ISAC) and the National Automated Clearing House
Association (NACHA).

Microsoft and its agents captured four hours of network traffic and
seized servers from two hosting locations in Pennsylvania and Illinois.
In addition, more than 1,700 domain names were analyzed to understand
their role in this business.
