Bank Hackers Stole Hundreds of Millions via Malware
In late 2013, an A.T.M. in Kiev started dispensing cash at seemingly random times of day. No one had put in a card or touched a button. Cameras showed that the piles of money had been swept up by customers who appeared lucky to be there at the right moment.
But when a Russian cybersecurity firm, Kaspersky Lab, was called to Ukraine to investigate, it discovered that the errant machine was the least of the bank’s problems.
The bank’s internal computers, used by employees who process daily transfers and conduct bookkeeping, had been penetrated by malware that allowed cybercriminals to record their every move. The malicious software lurked for months, sending back video feeds and images that told a criminal group — including Russians, Chinese and Europeans — how the bank conducted its daily routines, according to the investigators . . .
Kaspersky Lab says it has seen evidence of $300 million in theft through clients, and believes the total could be triple that. But that projection is impossible to verify because the thefts were limited to $10 million a transaction, though some banks were hit several times. In many cases the hauls were more modest, presumably to avoid setting off alarms . . .
But the largest sums were stolen by hacking into a bank’s accounting systems and briefly manipulating account balances. Using the access gained by impersonating the banking officers, the criminals first would inflate a balance — for example, an account with $1,000 would be altered to show $10,000. Then $9,000 would be transferred outside the bank. The actual account holder would not suspect a problem, and it would take the bank some time to figure out what had happened.
