A leak screenshot is an image shared by cyber attackers to demonstrate unauthorized access to a victim’s data or systems. Typically, these screenshots are posted on forums, dark web marketplaces, or social media as proof that the attackers have successfully breached a network or obtained sensitive information. Leak screenshots may display files, emails, databases, or other confidential materials, serving as evidence to pressure victims into paying ransoms or to attract buyers for stolen data. They are a common tactic in ransomware and data breach incidents to validate the authenticity of the attackers’ claims.
