Half of all rootkits still not detected by security software
By Davey Winder in Editorial
Now that the media interest in rootkits seems to have all but evaporated, you might be forgiven for thinking that the problem has been solved, that the bad guys have moved on to another mode of attack, that the good guys have won. Forgiven, but wrong.
According to recently published tests by those hardy chaps over at AV.Test who, funnily enough, spend pretty much their entire working lives being a thorn in the side of the AV industry by putting security products under the microscope and testing them until they burst, rootkits are still very much on the criminal radar.
The trouble is they are unlikely to be on yours because the AV.Test grilling has revealed that around half of the rootkits they used during the testing process went undetected by security suites and online web scanners alike. The German security boffins used both Windows XP Home Edition and Windows Vista Ultimate Edition in the tests which threw multiple rootkits onto the clean computing lab-rats as well as multiple malware infections that used those rootkit technologies to remain hidden.
As far as XP was concerned the security suites performed better than the online web scanners, catching 66 percent of the installations compared to 53 percent. Actually cleaning up and removing the detected rootkits proved to be a real problem for the web based scanners in particular, in fact they could only manage an average successful removal rate of just 32 percent. XP based dedicated rootkit detection and removal tools did better, although with an average detection rate of 80 percent it is hardly confidence inspiring if you ask me: they still left 20 percent of the evil little buggers running quietly away with the user none the wiser.
The Vista testing was a little confusing, using only those AV tools which had been updated or ‘frozen’ as of October 2007, and AV.Test reports that the average detection rate of 90 percent upon inactive samples was surprising as most of the samples involved were released two or three years previously. Certainly you might imagine a newly updated AV tool to find all of those. You might even imagine they could remove them, but only 54 percent were removed OK.
When it came to the more recent active rootkit installations, Windows Live Onecare did pretty badly considering it should have the edge when talking about things that hook into the Vista OS at kernel level. According to the report it could only detect one of the six installed and active rootkits.
So which tools proved to be the ones with big smiles on their binary faces? Only three AV solutions managed to detect and remove all the active and inactive rootkits thrown at them:
- F-Secure Anti-Virus 2008 6.80.2610.0
- Norton Antivirus 2008 15.0.0.58
- Panda Security Antivirus 2008 3.00.00
