In late 2011, the FBI released documents and data focusing on “Operation Ghost Click.” This malicious operation, leveraging a variety of DNSChanger-type malware, was defined by the FBI as an “international cyber ring that infected millions of computers.”
Associated malware samples and events can be traced back several years, and multiple platforms were targeted. To this day many remain affected or infected and are still open to compromise.
The amount of helpful data around this issue is plentiful. Even the FBI has provided a tool to check whether your host/IP is affected.
So, fast-forward to the present: Within McAfee Labs we have been flooded with queries (forgive the DNS pun) on what will happen on March 8, and what other impacts might ripple through our environments as the FBI takes the next steps toward concluding Operation Ghost Click.
The Good News!
On March 5, a U.S. District Court in New York signed an order to extend the March 8 deadline to July 9.
This extension will allow all affected entities to continue to track down and remediate against hosts that are still compromised. Current data indicates that there are still several million infected or affected hosts worldwide.
Also, as a handy reminder, the offensive Netblocks are well documented:
- 22.214.171.124 through 126.96.36.199
- 188.8.131.52 through 184.108.40.206
- 220.127.116.11 through 18.104.22.168
- 22.214.171.124 through 126.96.36.199
