Wired - Inside the Hunt for Russia’s Most Notorious Hacker 23min

America’s War with Russia’s greatest cybercriminal began in the spring of 2009, when special agent James Craig, a rookie in the FBI’s Omaha, Nebraska, field office, began looking into a strange pair of electronic thefts. ... The leading victim in the case was a subsidiary of the payments-processing giant First Data, which lost $450,000 that May. That was quickly followed by a $100,000 theft from a client of the First National Bank of Omaha. What was odd, Craig noticed, was that the thefts seemed to have been executed from the victims’ own IP addresses, using their own logins and passwords. Examining their computers, he saw that they were infected with the same malware: something called the Zeus Trojan horse. ... The ruse is known as a “man in the browser” attack. While you sit at your computer logging into seemingly secure websites, the malware modifies pages before they load, siphoning away your credentials and your account balance. Only when you log in from a different computer do you even realize the money is gone.
