The FBI’s carder forum sting, Operation Card Shop, led to 24 arrests announced on June 26, 2012: 11 in the United States and 13 abroad in seven countries. The FBI had operated an undercover carding forum called Carder Profit from June 2010 until May 2012. The 24 arrests were the announcement-day count—not the eventual total reported later.

What was Operation Card Shop?

Operation Card Shop was a two-year international FBI investigation into online carding. On June 26, 2012, the U.S. Attorney’s Office for the Southern District of New York and the FBI announced 24 arrests across 13 participating countries: 11 in the United States and 13 abroad. The announcement also reported more than 30 interviews and more than 30 search warrants. FBI announcement, June 26, 2012.

The 13 foreign arrests were in seven countries: six in the United Kingdom, two in Bosnia, and one each in Bulgaria, Norway, Germany, Italy, and Japan. Australia, Canada, Denmark, and Macedonia also took coordinated action, but the announcement did not count those countries among the seven where the 13 foreign arrests occurred.

Preet Bharara, then U.S. Attorney for the Southern District of New York, said, “As the cyber threat grows more international, the response must be increasingly global and forceful.” Janice K. Fedarcyk, then Assistant Director-in-Charge of the FBI’s New York Field Office, said the arrests caused “significant disruption to the underground economy.” These were officials’ assessments of their operation, not independent evaluations.

How did the FBI use Carder Profit?

The FBI said it established the undercover forum in June 2010 to identify and investigate people involved in carding and to prevent harm to victims. Carder Profit allowed discussion and offers to buy, sell, or exchange goods and services associated with carding. The FBI took it offline in May 2012.

According to the FBI, the forum recorded registered users’ discussion threads and private messages and logged their IP addresses. That access gave investigators a view of communications on the undercover forum; it does not, by itself, establish that every person who used it committed a crime. FBI account of the operation.

What did “carding” mean in the case?

In the official accounts, carding involved stolen credit-card, bank-account, or other personal information. The DOJ described uses including fraudulent purchases, producing counterfeit cards or identification documents, and selling stolen information. Carding forums could also be used to discuss hacking methods or vulnerabilities and to trade account data, counterfeit-card hardware, and goods bought with compromised accounts. These are descriptions of the activity under investigation, not findings against every forum member. DOJ follow-up, July 11, 2012.

Such forums were not necessarily open public message boards: official descriptions say they commonly restricted membership, used aliases and passwords, and included both public threads and private messages. In this operation, Carder Profit was an FBI-controlled forum configured to let investigators observe and record communications. FBI account; DOJ follow-up.

Why did reports say 24 arrests and later 30?

The figures refer to different stages of the investigation, so they should not be treated as conflicting counts for the same date.

Report Count and scope
June 26, 2012 announcement 24 arrests: 11 in the United States and 13 abroad in seven countries, as announced by the U.S. Attorney’s Office for the Southern District of New York and the FBI. Source.
July 11, 2012 DOJ follow-up 27 reported arrests, after three more people had been arrested since the June 26 announcement. Source.
Later DOJ sentencing release 30 defendants described as ultimately arrested in 13 countries. Source.

The June 26 announcement and the forum timeline place the 24-arrest action in 2012. The July follow-up contains a reference to “June 26, 2010,” but that date conflicts with those contemporaneous accounts and appears to be a typographical error.

What impact did the FBI report?

In its 2012 announcement, the FBI said the operation helped prevent estimated potential losses of more than $205 million, prompted notification about over 411,000 compromised credit and debit cards, and led to notifications to 47 companies, government entities, and educational institutions about network breaches. These are figures reported by the FBI at the time; the estimated potential loss figure is not a court finding or an independently established final loss total. FBI announcement.

What is known about later case outcomes?

A later DOJ release says Justin Mills was sentenced to six years in prison for trafficking in stolen identification information and describes 30 defendants as ultimately arrested. That is a documented outcome for Mills, not a complete account of every defendant’s case. The available official accounts do not establish a current case-by-case disposition for everyone involved. An arrest or complaint is not a conviction, and allegations attributed to defendants should not be read as proven conduct unless established in court. DOJ sentencing release.
