Cybercriminals behind the Tinba banking Trojan have been honing in on some of the larger banks in Russia and Japan, experts claim. Tinba is mostly used to pilfer banking credentials, passwords, and other information that s later used to perpetrate wire, or Automated Clearing House (ACH) fraud. The malware is called Tinba or Tiny Banker because the code behind it is so small, often as little as 20 kilobytes.
