Very similar to those microjoin exploits?

What droppers I could grab:

Droppers.rar

It nearly froze my vm and crashed it several times... Shitkit is a good name for it.

[Quads]

A lot of the files downloaded are detected /blocked as "W32.Spybot.Worm"

Quads

I submitted the dropper to Microsoft on the day that I discovered this one. They added a definition for the dropper about 2 hours later.

However, after the signature update, MSE did an exceptionally shitty job at detecting and removing the payload. It didn't even detect the primary rootkit driver, even though the file is visible on disk. I extracted the driver from the disk and scanned, still nothing. Submitted the driver a few days ago and they're still "processing" it.

Secondly, this bot actually drops three drivers:
ngoirye.sys in C:\WINDOWS\system32\drivers - 767KB (LOL), and locked for read access on disk. This is main driver. No detection...
srenum.sys in C:\WINDOWS\system32\drivers. Don't remember filesize. Very similar name to "serenum.sys", MS driver for serial port enumeration. I don't recall this driver being hidden either. MSE had detection for this driver even before dropper submittal.
ndisrd.sys in C:\WINDOWS\system32\drivers - 20KB. This driver doesn't appear malicious, and acts as some kind of packet filter.

The rest of the usermode garbage in C:\Documents and Settings\[current user]\Temp has various detection rates.

I gotta say, MSE has been taking their sweet ass time to analyze the 8 or so files I submitted from the payload to them. Kaspersky would've added every single one of them to the database in about 10 minutes.

Also, this infection disables regedit and breaks some explorer.exe stuff to prevent user from getting into Folder Options to turn "Show Hidden Files and Folders" back on. It was on, and the infection turned it off and literally deleted Folder Options from the menu in Explorer and Control Panel.

Really messy.

Attached ngoirye.sys and ndisrd.sys in RAR.

[Elite]

ngoirye.sys - http://www.virustotal.com/file-scan/rep ... 1282856138

ndisrd.sys, which isn't malicious after all - http://www.virustotal.com/file-scan/rep ... 1282856116

Hi Elite, may I ask how or what you used to extract the driver?

The .sys files can't install via Sandboxie but do install via VM.

[Elite]

I used RkU's copy-file function for the protected driver.

[Jaxryley]

I used RkU's copy-file function for the protected driver.

Great, thanks for sharing Elite.

[Elite]

MS finally detects locked driver.

About time...
