On Tuesday, May 22, Google announced it would throw its weight into the awareness campaign, rolling out alerts to users via a special message that will appear at the top of the Google search results page for users with affected computers, CNET reported.
“We believe directly messaging affected users on a trusted site and in their preferred language will produce the best possible results,” wrote Google security engineer Damian Menscher in a post on the company’s security blog.
“If more devices are cleaned and steps are taken to better secure the machines against further abuse, the notification effort will be well worth it,” he wrote.
The challenge, and the reason for the awareness campaigns: Most victims don't even know their computers have been infected, although the malicious software probably has slowed their web surfing and disabled their antivirus software, making their machines more vulnerable to other problems.
On the night of the arrests, the agency brought in Paul Vixie, chairman and founder of Internet Systems Consortium, to install two Internet servers to take the place of the truckload of impounded rogue servers that infected computers were using. Federal officials planned to keep their servers online until March, giving everyone opportunity to clean their computers.
But it wasn't enough time.
A federal judge in New York extended the deadline until July.
This is what happened:
Hackers infected a network of probably more than 570,000 computers worldwide. They took advantage of vulnerabilities in the Microsoft Windows operating system to install malicious software on the victim computers. This turned off antivirus updates and changed the way the computers reconcile website addresses behind the scenes on the Internet's domain name system.
The DNS system is a network of servers that translates a web address -- such as http://www.foxnews.com -- into the numerical addresses that computers use. Victim computers were reprogrammed to use rogue DNS servers owned by the attackers. This allowed the attackers to redirect computers to fraudulent versions of any website.
The hackers earned profits from advertisements that appeared on websites that victims were tricked into visiting. The scam netted the hackers at least $14 million, according to the FBI. It also made thousands of computers reliant on the rogue servers for their Internet browsing.
