Mounties in Alberta are warning homeowners about a fake wireless network claiming to be from the RCMP.

Police say there have been two incidents in the Calgary area in which people with wireless routers noticed an unauthorized computer connection which identified itself as "RCMP Surveillance."

The owners contacted the RCMP, who told them that was not one of their computers.

One person noticed a car in an open field area near his residence, and when he logged into his computer, he discovered that a connection had been made to his Internet through his Wi-Fi identified as "RCMP Surveillance."

Mounties say they do not use wireless connections for security reasons.

They say if anyone detects any computer accessing their Wi-Fi, whether named with any form of RCMP or not, should shut their system down immediately as that computer may be attempting to access the Internet for malicious or illegal purposes.

Those could include child pornography, Internet scams and computer hijacking.

Those using a Wi-Fi router should realize that anyone within a limited area surrounding that router could access their computer unless the security settings have been completely enabled.

This includes setting passwords, limiting computer access to specific authorized computers and restricting the broadcast of the Wi-Fi name itself so only authorized users are able to sign onto the system.

If anyone feels their computer systems may have been compromised by an unauthorized computer then they should check with their Internet service provider and if illegal activity is detected, call police.
