Windows malware infections from Autorun exploits down by 82% from 2010
According to a Microsoft Technet Blog article published on June 14, 2011, Malware infections resulting from exploits involving Autorun (like when you plug in a USB memory device and it runs a program or setup automatically) have dropped by 82% from the numbers recorded during the same period in 2010.
The percentage of decline varied with the operating system and service pack installed. Windows XP users who have Service Pack 3 installed saw a 62% drop in Autorun installed malware, after accepting the optional patch issued on Feb 8, 2011, or the forced installation of the reissued patch, pushed out on February 24, 2011.
If you are operating a Windows XP computer with any service pack older that SP 3, your version of Windows is now out of support and you are no longer receiving any critical patches. Thus, your computer is not protected against this, or any other recently patched vulnerabilities. If it is connected to the Internet, or if you plug in an infected USB device, unless you have manually edited your computer's Registry to disable Autorun, or it is running industrial strength anti-malware protection, it will eventually become infected and probably botted.
Computers running on Windows Vista with SP1 saw a 68% decline, while those with SP2 installed had a whopping 82% drop in malware installations.
Note! Microsoft will stop supporting Windows Vista Service Pack 1 on July 12, 2011. From that date onward, Microsoft will no longer provide support or free security updates for Windows Vista Service Pack 1 (SP1). You folks need to upgrade to Vista SP 2 by July 12, 2011, or you will not receive any more updates or patches.
Why have Autorun infection rates dropped so dramatically?
The drop in malware infections from Autorun exploits is attributable to patch KB971029 that Microsoft released optionally, with the Windows Updates of February 8, 2011, which turned OFF Autorun for "non-shiny" media (e.g. CDs, DVDs) and two weeks later, as a non-optional update. Before then, if you plugged a USB stick (a.k.a. thumbdrive, flash drive) into your Windows XP or Vista computer and there was a setup file on that memory device, it would run automatically. With the update installed, flash drives inserted into a PC running XP (SP3), or Vista no longer offer the option to run programs. However, the demise of AutoRun does not affect CDs or DVDs (just USB devices or shared network drives).
Some notorious infections went so far as spoofing the wording of options on the dialog box that usually opens when you plug in a USB device. The wording was crafted to induce unwary users into choosing the spoofed option, which was rewritten to appear that if clicked upon, it would open the drive as a folder, for them to look at. In fact, that option was still there, as the next option down! The first one executed a hidden file on the device, named "autorun.inf" - which triggered a hidden executable file on the drive, which was a malware/spyware setup file. Because of its being the first choice and the craftiness of the wording, many thousands of intelligent people were fooled into clicking it and installing the malware contained on those devices.
It was by means of infected thumb-drives that allowed the Conficker Worm to spread so widely and quickly in late 2009 and early 2010.
