I have written a great deal about how organized cyber gangs in Eastern Europe drained tens of millions of dollars from the bank accounts of small- to mid-sized businesses last year. But new evidence indicates one of the gangs chiefly responsible for these attacks managed to hack directly into a U.S. bank last year and siphon off tens of thousands of dollars.
On July 30, 2009, at least five individuals across the United States each received an electronic transfer of funds for roughly $9,000, along with instructions to pull the cash out of their account and wire the funds in chunks of less than $3,000 via Western Union and Moneygram to three different individuals in Ukraine and Moldova.
The recipients had all been hired through work-at-home job offers via popular job search Web sites, and were told they would be acting as agents for an international finance company. The recruits were told that their job was to help their employers expedite money transfers for international customers that were — for some overly complicated reason or another — not otherwise able to move payments overseas in a timely enough manner.
The money was sent to these five U.S. recruits by an organized ring of computer thieves in Eastern Europe that specializes in hacking into business bank accounts. The attackers likely infiltrated the bank the same way they broke into the accounts of dozens of small businesses last year: By spamming out e-mails that spoofed a variety of trusted entities, from the IRS, to the Social Security Administration and UPS, urging recipients to download an attached password-stealing virus disguised as a tax form, benefits claim or a shipping label, for example. Recipients who opened the poisoned attachments infected their PCs, and the thieves struck gold whenever they managed to infect a PC belonging to someone with access to the company’s bank accounts online.
