Researchers at anti-virus firm Kaspersky Lab have discovered a new Tor-based banking trojan. ChewBacca is based on Tor network and aimed at 64-bit systems. Malware is compiled with Free Pascal 2.7.1.1 and also drops a copy of Tor 0.2.3.25, which runs with a default listing on “localhost:9050” The Trojan then logs all keystrokes and sends the data back to the botnet controllers via Tor anonymity network.
