DNSChanger "D-day" is fast approaching!

ACMA Media Release 43- 14 June 2011

D-day is coming for people whose computers are infected with the DNSChanger malicious software (malware). Computers that remain infected after 9 July 2012 will have severely crippled internet access, so it's time to check your computer now.

It's also time to check that your computer's settings for accessing the internet are not the 'rogue' settings installed by DNSChanger. Even if you have removed DNSChanger malware, it is possible your computer is still using the rogue settings, which will also severely cripple your internet access after 9 July.

The ACMA estimates that between 7,000 to 7,500 Australian internet users are either infected with DNSChanger or are continuing to use the rogue settings.

How can you tell whether you are infected with DNSChanger or using the rogue settings?

  • Simply visit the dns-ok.gov.au website. If the website detects that you are infected by DNSChanger or using the rogue settings, you will see a red banner warning stating 'You appear to be affected by DNSChanger.' You will then be able to access remediation tools and advice on the steps you can take to return your computer to normal operation and restore correct settings for accessing the internet.

What is significant about 9 July 2012?

  • In November 2011 the United States FBI worked with the Internet Systems Consortium to set up a temporary solution for those infected with DNSChanger, enabling them to continue to access internet services. This solution will be switched off on 9 July 2012.

The DNSChanger threat is a timely reminder for Australian internet users to protect themselves from malware and adopt safe internet practices. These are key messages of National Cyber Security Awareness Week, which runs from 12 to 15 June 2012, with over 500 industry, community and consumer organisations and government agencies participating to deliver events across Australia.

Additional information about DNSChanger is available at the dns-ok.gov.au.
