Modem hijacking - It's crazy , be careful

Hi read this I got this information via e-mail , Modem hijacking - It's crazy , be careful

What is modem hijacking and how does it happen?


Modem hijacking is not a new problem, but it still can affect people using a dial up modem. You could be surfing around the Internet and without realizing it, have malicious software downloaded to your computer. This software disconnects you from your usual dial-up Internet connection and reconnects you on another, expensive phone line. Even when your computer sits idle for long periods of time, this dialer may still be hooking you up to international numbers and sending the charges to your phone bill

  
Modem hijacking can occur when a web site asks you to do the following to access their web site information:  

  •  download a file via a pop-up window
  •  accept their Web site's Terms and Conditions 
  •  download a special viewer or dialer to access content etc…

The file or download then accesses software on your computer to use your modem to dial phone numbers in foreign countries resulting in long distance charges and/or connection fees appearing on your phone bill. The file may also hide behind pop-up ads activated from previous web browsing.

 

 
What are the typical signs of modem hijacking

  •  You hear your modem disconnect and dial-up again.
  • Your internet speed becomes much slower than normal. There may be other reasons for this but when checking, always start by looking at your dial-up settings and properties.
  • You receive an unexpectedly high phone bill, which lists unknown and high-cost international phone numbers.
  • You see an unfamiliar short-cut icon on your desktop.
  • You are online but cannot send emails etc…

How can I protect myself?

 
If you have high speed Internet (ADSL or cable modem) you would not be susceptible to this scam. However, if you have high speed Internet and a dial up connection such as a fax modem you may be susceptible. Ensure you disconnect all dial-up connections when not in use. For example: If you have a fax modem connected to your computer, disconnect it when not in use.

 
  • Do not download programs from Websites or sources you don't know or trust.
  • Carefully read disclaimers, Terms and Conditions and warnings before downloading information.
  • Supervise your children's Internet activities.
  • Keep your anti-virus software current.
  • Remove any network and dial-up connections on your computer that you are not familiar with.
  • Check your phone bill to verify your long distance charges.
