The battle to disrupt the Anonymous collective is underway. The latest campaign has been directed at Spanish-speaking activists.
Spanish cops arrested several suspects earlier this week and further arrests followed in South America.
The group now says it wasn't police technical sleuthing that got them but infiltration of one website used by them.
Interpol, which announced the arrests Tuesday, did not say how it encountered the 25 suspects, who it says were involved in cyberattacks originating from Argentina, Chile, Colombia and Spain that targeted sites including Colombia’s defense ministry and presidency and Chile’s Endesa electricity company and national library.
Activists encountered in the chat room said some of those arrested belonged to a group of hackers called Sector404 while others were unsophisticated activists who took part in denial-of-service attacks, which overwhelm websites with data requests.
“The GREAT majority of those implicated were people inhabiting the servers of anonworld.info, something that disconcerts us,” said the activist “Skao,” who identified herself as a law student.
In the communique released on its blog, Anonymous Iberoamerica said the 25 were snared not through “intelligence work or informatics strategy” but rather through “the use of spies and informants within the movement.”
The activists said many of those arrested had been careless, leaving digital tracks.
