PEnetration TEsting Proxy (PETEP)

Capturing network communication based on the TCP protocol and modifying it by creating a specialized Man-in-the-Middle proxy is one of many practices used for searching for security flaws in network applications. In this article, we will focus on the use of the cross-platform open-source application PETEP for testing fat clients using TCP protocols and show a simplified attack procedure on a sample vulnerable application.
