Abstract:

In recent years, social networking worms

propagating through users’ interactions appear frequently. These worms trick users to click

worm links by exploiting social engineering techniques, and it poses a serious threat to the

Internet. A dynamic worm propagation model based on social network is proposed, and the worm

propagation process between network nodes is drawn out. Validity of the model is verified by

the simulation, and the influence of the worm propagation is analyzed by the number of

online users, the probability of users click worm links, the release time of immune patches

and the quantity of users installed patches.

Key words: social network;social engineering;dynamic worm propagation model
