Troj/Bancos-DA is a password stealing Trojan aimed at customers of Brazilian banks.
Troj/Bancos-DA will monitor a user's internet access. When certain internet banking sites are visited, the Trojan will display a fake login screen in order to trick the user into inputting their details.
Troj/Bancos-DA will then send the stolen details to an email address.
When first run, Troj/Bancos-DA will copy itself to <Windows>\kernels32.exe.
Troj/Bancos-DA will set the following registry entry to run on user startup:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Run
Service System
\<Windows>\kernels32.exe\
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Service System
\<Windows>\kernels32.exe\
Troj/Bancos-DA may also display a fake error message box with the title "FIND ERROR" and the message "Requerido Windows NT Server".
