Hwp.exe in Apr. 8 CVE-2011-0611 Flash Player Zero day - SWF in DOC/ XLS - Disentangling Industrial Policy..


According to Cédric Gilbert (SkyRecon R&D), the shellcode’s last command include a “taskkill /im hwp.exe”. This hwp.exe file could be related to a South-Korean Word Processor Software :
“Hangul Word Processor or HWP”. According to Wikipedia :
“It is used extensively in South Korea, especially by the government.“
According to Hangul’s website, this word processor handle Microsoft .DOC & .DOCX documents.
So the questions are
  1. Is the infected doc with zero-day also ‘compatible’ with it ?
  2. Was it used on targets in Korea or targets who use this processor?
  3. Was it made in Korea?

Your comments and thoughts are welcome.
thanks,
Mila

P.S. Korea came up before in this  http://bugix-security.blogspot.com/2010/09/cve-2010-2883-made-in-korea.html

Please welcome "Targeted Email Attacks http://targetedemailattacks.tumblr.com"


Targeted Email Attacks
http://targetedemailattacks.tumblr.com/  

these are targeted attacks received by the US-Taiwan Business Council. We are not related but somehow share the same set of overseas "friends" - I recognize many messages posted there and even received targeted messages designed to look like they came from that organization.
The author does not post samples but provides links to Virustotal  so it gives a good idea of what it is.

Contagio data - targeted email senders by country / source

 It is what it is.  Analysis of email headers from emails sent to one targeted domain (Nov, 2009 - April 2011). Headers were analyzed to find IP addresses of the sending mail servers. Some of them are compromised, some belong to/leased by attackers. Only Gmail does not allow tracing the senders IP. It is shame, I wish they listed the sender IP addresses.

I can post more detailed statistics, if you are interested, drop me a line.
My dataset is small and not great for industry averages but I still think it is a good representative of the of the situation.

Please note this is based on Contagio data only, which includes targeted messages with malicious attachments meant to compromise networks, steal data (so called APT stuff) and does not include regular spam, banking trojans, and mass mailed malware.
