# Exploiting Client (#3)

A threat cluster where an attacker targets and leverages flaws originating directly within the source code implementation of any software acting in a client role (requesting/processing data from a server or resource). These vulnerabilities allow manipulation of client behavior or unauthorized access using Exploit Code, often when the client interacts with malicious content. The generic vulnerability is the presence of exploitable flaws within client-side source code stemming from insecure coding practices.
