DNSChanger Malware

Original Post Published by the US-CERT
In November 2011, U.S. Federal prosecutors announced Operation Ghost Click, an investigation that resulted in the arrests of a ring of seven people who allegedly infected millions of computers with DNSChanger malware.

The malware may prevent users’ anti-virus software from functioning properly and hijack the domain name system (DNS) on infected systems. Systems affected by DNS hijacking may send internet requests to a rogue DNS server rather than a legitimate one.

To prevent millions of Internet users infected with the DNSChanger malware from losing Internet connectivity when the members of the ring where arrested, the FBI replaced rogue DNS servers with clean servers.

However, the court order allowing the FBI to provide the clean servers is set to expire on March 8, 2012. Computers that are infected with the DNSChanger malware may lose Internet connectivity when these FBI servers are taken offline.

US-CERT encourages users and administrators to utilize the FBI’s rogue DNS detection tool to ensure their systems are not infected with the DNSChanger malware. Computers testing positive for infection of the DNSChanger malware will need to be cleaned of the malware to ensure continued Internet connectivity.

Users and administrators are encouraged to implement the following preventative measures to protect themselves from malware campaigns:
