Hacker Hunters Hacker hunters are the new breed of crime fighter. They employ the same methodology used to fight organized crime in the 1980s-informants and the cyberworld equivalent of wiretaps. Daniel Larking, a 20-year veteran who runs the FBI's Internet Crime Complaint Center, taps online service providers to help track down criminal hackers. Leads supplied by the FBI and eBay helped Romanian police round up 11 members of a gang that set up fake eBay accounts and auctioned off cell phones, laptops, and cameras they never intended to deliver. The FBI unleashed Operation Firewall, targeting the ShadowCrew, a gang whose members were schooled in identity theft, bank account pillage, and selling illegal goods on the Internet.

ShadowCrew's 4,000 gang members lived in a dozen countries and across the United States. For months, agents had been watching their every move through a clandestine gateway into their website, shadowcrew. com. One member turned informant and called a group meeting, ensuring the members would be at home on their computers during a certain time, when the Secret Service issued orders to move in on the gang. The move was synchronized around the globe to prevent gang members from warning each other via instant messages. Twenty-eight gang members in eight states and six countries were arrested, most still at their computers. Authorities seized dozens of computers and found 1.7 million credit card numbers and more than 18 million email accounts.

ShadowCrew's Operations The alleged ringleaders of ShadowCrew included Andres Mantovani, 23, a part-time community college student in Arizona, and David Appleyard, 45, a former New Jersey mortgage broker. Mantovani and Appleyard allegedly were administrators in charge of running the website and recruiting members. The site created a marketplace for more than 4,000 gang members who bought and sold hot information and merchandise. The website was open for business 24 hours a day, but since most of the members held jobs, the busiest time was from 10 p.m. to 2 a.m. on Sundays. Hundreds of gang members would meet online to trade credit card information, passports, and even equipment to make fake identity documents. Platinum credit cards cost more than gold ones, and discounts were offered for package deals.

One member known as "Scarface" sold 115,695 stolen credit card numbers in a single trade. Overall, the gang made more than $4 million in credit card purchases over two years. ShadowCrew was equivalent to an eBay for the underworld. The site even posted crime tips on how to use stolen credit cards and fake IDs at big retailers. The gang stole credit card numbers and other valuable information through clever tricks. One of the favorites was sending millions of phishing emails-messages that appeared to be from legitimate companies such as Yahoo!-designed to steal passwords and credit card numbers. The gang also hacked into corporate databases to steal account data.

According to sources familiar with the investigation, the gang cracked the networks of 12 unidentified companies that were not even aware their systems had been breached. Police Operations Brian Nagel, an assistant director at the Secret Service, coordinated the effort to track the ShadowCrew. Allies included Britain's national high-tech crimes unit, the Royal Canadian Mounted Police, and the Bulgarian Interior Ministry. Authorities turned one of the high-ranking members of the gang into a snitch and had the man help the Secret Service set up a new electronic doorway for ShadowCrew members to enter their website. The snitch spread the word that the new gateway was a more secure way to the website. It was the first-ever tap of a private computer network. "We became shadowcrew. com ," Nagel said. Mantovani and Appleyard were slated for trial. Authorities anticipated making additional arrests.
