Both Microsoft Certified Professional and Computerworld report on a variation of Conficker known as “Neeris.” Neeris is a 4-year-old virus that has resurfaced and is now behaving like a Conficker wannabe. It is believed that the criminal hackers who created Conficker and Neeris are either the same person or are working together, double-teaming the computer security community.

Neeris began showing up on March 31st into April 1st which, as we know, was supposed to be the launch date for the next set of Conficker updates.

Conficker and Neeris both include auto-run and remote call features that allow it to slither into external storage, including cameras, USB drives, external hard drives and other memory-based devices. Furthermore, it is feared that the “call home” feature will eventually enable either virus to update their abilities to wreak havoc and compromise data.

What’s troubling is that Microsoft created a critical security update specifically for Conficker, labeled the MS08-067 patch. Now, Microsoft Certified Professional states that Neeris is able to “poke holes in” this patch, indicating that the patch is no match for Neeris.

However, as stated in Computerworld, “Due to the similarities to Conficker, most of the mitigations that were mentioned also apply here. Make sure to install MS08-067 if you haven’t done so yet, and be careful to use only autoplay options you’re familiar with, or consider disabling the Autorun altogether.”

Regardless, update critical security patches and run the latest McAfee anti-virus definitions.
