Brief Description 

    

Bancos.UU is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.

 

Bancos.UU prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).

Bancos.UU redirects attempts to access web pages of certain banks to spoofed pages, with the aim of logging information entered by the user in these pages.

Bancos.UU redirects attempts to access several web pages to a specific IP address.

 

It uses stealth techniques to avoid being detected by the user:

  • It uses techniques included in its code to hide itself while it is active.
  • It modifies system permissions in order to hide itself.

 

Bancos.UU uses the following propagation or distribution methods:

  • Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
  • Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
  • Computer networks (mapped drives): it creates copies of itself in mapped drives.
