The FBI and its counterparts in Europe, Brazil, and elsewhere have arrested more than 60 people suspected of carrying out hacking crimes associated with a secretive online forum known as Darkode, according to media reports.
Darkode, according to a post published in April 2013 by KrebsOnSecurity, has long acted as an online bazaar for criminals looking to buy and sell drive-by exploits, spam services, ransomware programs, botnet tools, and other illicit products and services. According to news organizations located in Brazil, the site has been under investigation since March by agents with the FBI Europol, Brazil's Federal Police, and law enforcement agencies in other countries. The operation has resulted in 62 arrests in 18 countries, including Germany, the UK, Romania, Bosnia, Serbia, India, Sweden, Denmark, and Colombia, according to the reports.
A Public information agent with the FBI didn't respond to an e-mail seeking details of the reported enforcement operation. Some of the articles detailing the arrests are here, here, and here.
