Fake Flash updates are leveraged as a very popular trick amongst attackers to fool users into downloading and installing malware. This week we found a three websites distributing Win32.Sanity.N malware disguised as Flash updates:
- hxxp://kivancoldu.com/, redirects to hxxp://click-videox.com/
|http://kivancoldu.com on 05/02/2013|
- hxxp://fastcekim.com/, redirects to hxxp://click-videox.com/
- hxxp://kivanctatlitug.tk/ d(down)
The fake warning at the top of the page alternates between English and Turkish.
What is interesting is that the malicious executables are actually hosted in a DropBox account and have not been taken down since they were found about seven days ago. I have spotted two different executables so far:
- FlashPlayer.sfx.exe (detected by only 2 of 46 AV vendors)
- Videonuizle.exe (detected by 5 of 46 AV vendors)
These two files have similar behavior. They disable all Windows features: UAC, Firewall, AV, Safe Boot, etc. The malware then drops variants of the Sality virus, some of which have a good detection rate amongst AV vendors.
Interestingly, there is a link on the malicious websites that shows how many people visited it. There were 1,412 unique visitors in a single day.
