New Trojan Balances Your Checkbook

"New malware being used by cybercrooks does more than let hackers loot a bank account; it hides evidence of a victim’s dwindling balance by rewriting online bank statements on the fly, according to a new report.

"The sophisticated hack uses a Trojan horse program installed on the victim’s machine that alters html coding before it’s displayed in the user’s browser, to either erase evidence of a money transfer transaction entirely from a bank statement, or alter the amount of money transfers and balances.

"The ruse buys the crooks time before a victim discovers the fraud, though won’t work if a victim uses an uninfected machine to check his or her bank balance.

"The novel technique was employed in August by a gang who targeted customers of leading German banks and stole Euro 300,000 in three weeks, according to Yuval Ben-Itzhak, chief technology officer of computer security firm Finjan."
