About Targeted Attacks knowledge I know is really too little, so every time when colleagues have filed, I can only be there to hear them say, then one colleagues when speaking of the Targeted Attacks, is what I don’t even understand this one of my colleagues say, now Targeted Attacks knowledge is really useful, I should learn, then heard him saying that, I really was very embarrassed, but I think what he said is reasonable, then the fire of knowledge, but I also do not understand, are really behind the times so, I decided to learn Targeted Attacks knowledge, but I do not know from He Xueqi, so I think, or consult colleagues, I go to learn a good Targeted knowledge of Attacks.
