**2.2 Privacy threats in social media applications**

Social media platforms are highly vulnerable to stalking attacks. One of the common stalking techniques involves an online mob of anonymous self-organized groups to target individuals, causing defamation, threats of violence, and technology-based attacks. Social media are used to build trust between the perpetrator and the victim. Perpetrator is a person who may carry out a harmful, illegal and immoral act. When victim transmits confidential data including pictures and videos, the perpetrator can intercept, steal confidential data and abuses them for blackmail purposes [5]. Social media firms are also responsible to identify user with such malicious intentions, block them and initiate appropriate legal actions as per the law.
