RipGof malicious code does not exist as a distribution in the underground, leading investigators
|
to look into the original RipGof.A malicious code. Over a year prior to the 2006 targeted attacks
|
RipGof.A emerges in the wild. RipGof.A attempted to exploit the Jet Engine Database exploit in
|
March 2005. This proves attempted exploitation and installation of code through RipGof for a
|
year prior to more sophisticated codes and attacks.
|
In summary, RipGof and GinWui attacks both use the same private exploit code against
|
Microsoft Word and both install rootkit based codes to steal and send information back to
|
Chinese sources. This circumstantial evidence reveals that Wicked Rose and the NCPH group
|
likely began their exploitation efforts at least a year and a half to two years prior to sophisticated
|
attacks that commenced in 2006. Once the group found a vulnerability within Microsoft Word
|
they were able to improve upon it and their targeted attack techniques to distribute multiple
|
targeted attacks and malicious codes for criminal gain as hackers for hire.
|
Timeline of Events
|
Wicked Rose and the NCPH hacking group are implicated in multiple Office based attacks over
|
a two year period. An attack in 2006 used RipGof.B in the attack. RipGof.A first emerged a
|
year earlier using an exploit that is relatively unsophisticated. Over the next year the Evil
|
Security Team, also out of China, creates the Dasher worm and uses the PcShares Trojan in an
|
attack. Wicked Rose gives a recommendation on the Trojan the day it is updated in the spring of
|
2006, showing a close affiliation between Wicked Rose and the Evil Security Team actors.
|
Multiple attacks that take place in May and June and later 2006 are related to privately held
|
exploit code for both Microsoft Word and Excel, proven to be developed by Wicked Rose. A
|

|
A Pictorial Introduction to Wicked Rose and NCPH
|
Just who are Wicked Rose and the NCPH hacker group? As it turns out, a collection of college
|
students in China who likely room with one another and regularly support their hacking interests.
|
In-depth research implicates Wicked Rose as the ring-leader of the group, responsible for
|
managing hacker for hire relationships and paying group members for their work as hackers.
|
During the time of targeted attacks in 2006 their income increased significantly, to full-time
|
wages for part time hacking. Wicked Rose, leader of the group, is pictured below:

|
Rose is an approximate 20-year-old (2006) student at the Sichuan University of Science &
|
Engineering. In the spring of 2006 Wicked Rose claims to have dropped out of school for full
|
time hacking opportunities. Specifically, on April 30, 2006 his blog entry claims he did not
|
register for his university exam. He performed significant updates to his rootkit code from
|
March through June 2006. He later returned to school by September 2006.
|
Wicked Rose claims responsibility on his blog for targeted e-mail based attacks containing
|
Microsoft Word and CHM exploits from the spring of 2006.
