ESET researchers have already unearthed a new Trojan that targets Litecoins - a peer-to-peer crypto currency inspired by and technically nearly identical to Bitcoin.
According to their analysis, the Trojan is pretty basic, as the only thing it attempts to do is to send the user’s wallet.dat file to an FTP server under the control of the attacker. Another good news is that it's not very widespread.
According to the researchers, the web provider hosting the attacker's FTP domain has been made aware of the attacker's malicious efforts and has set up a warning to pop up when someone visits the domain:
I wonder how the provider has managed to discover the attacker's username on the exchange and if his investigation lead him to the right user. Also, this does not help infected users at all.
As a side note, the Skynet Trojan is still going strong. Not only does it use the infected computers for mining Bitcoins, but the Tor-powered botnet they have been roped into is also used to carry out DDoS attacks against Bitcoin exchanges.
