Study on Techniques to Defend Against Social Network Sybils

Abstract

Unscrupulous users increasingly find
Online Social Networking (OSN) platforms as
lucrative targets for malicious activities, such as
sending spam and spreading malware. The
profitability of such activities and the fact that a large
portion of the OSN communication takes place over
social links (e.g., Facebook) that are symmetric in
nature, motivate attackers to connect to real users. In
particular, attackers take advantage of the open
nature of OSNs and send to legitimate users unwanted
friend requests, also known as friend spam.These
friend spams have proven to be among the most
evasive malicious activities
