Anti-forensics is a big challenge that cyber forensic experts encounter with the modern cybercriminals. These are a collection of tools and techniques used to damage, erase, or modify data that obstructs the normal forensic examination. Anti-forensic measures performed on a device will harm the integrity of the data and could compromise the investigation. The common intent of anti-forensics tools is completely for a malicious intent. Anti-forensics or counter-forensics could be an option to defend against espionage as recovery of information by forensics tools could be minimized.
