In the world of Chinese Hackers there seems to be a group especially for female hackers. I just read this post: Chinese Female Hacker Group which show a pretty high growth rate of women joining:
The website for the China Girl Security Team was registered on 12 Mar 2007 and currently has 2,217 members. The leader of the group Xiao Tian, is only 19 years old
Thats good , first time i ever heard abt female hackers. Since my university days i havent met any female who is into networks or network security.
