A US judge has granted a four-month extension for the operation of temporary DNS servers installed to combat a trojan affecting three million PCs globally.
The extension request, published by security blogger Brian Krebs, would delay the replacement of the rogue servers used in the malware distribution for another 120 days, giving businesses and governments additional time to react to the infections.
According to the IDD report, “if an enterprise's employee has DNSChanger on their computer, it means that enterprise is susceptible to having their proprietary information stolen".
IDD updated its infection figures last week, indicating a major downturn in the number of affected enterprises. The extension given on Monday could lead to an even more dramatic decrease in the contagion.
As well as disabling anti-virus and software updates for users, the DNSChanger malware redirects infected computers to malignant sites via the rogue DNS servers, located at data centers in Manhattan and Chicago.
While businesses and government agencies were a target of the trojan, home users were also affected.
Arrests in relation to the attack -- which hauled in an estimated $14 million, according to the FBI -- were made in November after a two-year investigation.
The FBI is currently seeking the extradition of six Estonian nationals linked to the attacks, who, according to them, used the malware to “manipulate the multi-billion-dollar internet advertising industry".
