Brief Description 

    

Dialer.HRA is a dialer type malware. Dialers usually try to establish phone connections with high rate numbers, significantly increasing the phone bill of the affected user.

Dialer.HRA affects computers that use a modem to connect to the Internet, as the virus modifies the Dial-up network access settings. It changes the telephone number provided by the ISP (Internet Service Provider), which is a local-rate number, to a high-rate number.

 

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

Dialer.HRA 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.

Dialer.HRA redirects attempts to access several web pages to a specific IP address.

 

Dialer.HRA 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.
