Comment Same trojan attacked Dutch bank (Score 3, Interesting) 196
The Dutch bank was attacked by the 'man in the browser' type of trojan, which cached the output from the challenge-response between user- and bank. This bank by default performs two challenge-response sequences;
1) when loggin in
2) when confirming a transaction
A third, is performed when transferring large amaounts of money.
Appearently, the trojan told the customer the first attempt had failed, (while in the background preparing a transaction, which could be verified by the bank, because the client was so kind to re-autenticate (this time to the transaction challenge, while they were still thinking it was the login challenge)
Here's the story (in Dutch, hurrah)
