Forensic Investigations of Social Media Apps: Tools and Techniques 

Nowadays, Social media platforms are used at large scale to communicate each other and share content and communicate with others, making them an easy and rich source of digital evidence in forensic examination. Law enforcement agencies, private investigators, companies and computer/cyber forensic experts often depend on social media data in criminal acts and in civil cases and corporate examinations.

This article will detect the equipment, techniques and challenges involved in social media forensic investigation. 

Importance of Social Media in Forensic Investigation 

Social media apps provide a treasure of digital evidence, including: 

• Communication Records: Direct messages, post, and interaction.
