Recently, all ISPs in North America were advised by government authorities that a small subset of our customer base has been infected by malicious software (malware) called DNSChanger. This specific malware is a phenomenon that has affected many Internet providers across the globe and in Canada, including Interface Technologies.
DNSChanger is also known as TDSS, Alureon, TidServ or TDL4.
What does DNSChanger do?
DNS Changer malware causes a computer to use rogue DNS servers, controlled by cyber criminals, instead of a legitimate one that is generally provided by your Internet service provider.
This malware resides in your computer, but can also affect your home network. It may leave you vulnerable to criminal organizations that could misuse and redirect your Internet traffic.
How to detect the DNSChanger malware
- Visit www.dns-ok.ca. This website checks your computer settings to see if it’s infected with DNSChanger. If the screen is green, you’re not affected. If the screen is red, your computer is infected with the DNS Changer malware. Perform this check on all the computers/laptops within your household.
Please note: if your computer is infected, you must have the malware removed by July 9th, 2012, in order to avoid disruption to your Internet service.
- The Government of Canada, via the Canadian Cyber Incident Response Centre and Public Safety Canada, has various means of identifying if your computer is affected. Learn more.
