Brief Description 

    

Dialer.IBY 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.IBY 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.

 

It captures certain information entered or saved by the user, with the corresponding threat to privacy: .

 

It affects productivity, preventing tasks from being carried out:

  • In the affected computer: causes system slowdowns.
  • In the local network: it generates a large amount of network activity and consumes bandwidth.

 

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

  • It deletes the original file from which it was run once it is installed on the computer.

 

Dialer.IBY does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
