Credential Stuffing
An automated attack where stolen account credentials from one data breach are used to gain unauthorized access to other unrelated services.
Overview
Because users frequently reuse passwords across multiple platforms, a credential harvested from a simple phishing site can compromise a corporate VPN or banking portal. Credential stuffing uses bots to rapidly test thousands of stolen username/password pairs across hundreds of websites. This highlights the severe secondary impact of phishing. PhiShark prevents credential stuffing at the source by utilizing Agentic AI to block the initial credential-harvesting phishing campaigns, cutting off the supply chain of stolen data that fuels these automated attacks.
