Open Source C MiTM (Man-in-The-Middle) Attack Tools

Ettercap is a multipurpose sniffer/interceptor/logger for switched LAN. It supports active and passive dissection of many protocols (even ciphered ones) and includes many feature for network and host analysis. Development has been moved to GitHub, https://github.com/Ettercap/ettercap

Cross-platform high-level cryptographic library. Themis helps to build simple and complex cryptographic features easily, quickly, and securely. It’s a perfect fit for multi-platform apps. Themis hides cryptographic details and eliminates popular mistakes. Themis provides ready-made building blocks (“cryptosystems”) for secure data storage, message exchange, socket connections, and authentication. Secure Cell is a multi-mode cryptographic container suitable for storing anything from encrypted files to database records. Use Secure Cell to encrypt data at rest. Secure Cell is built around AES-256-GCM, and AES-256-CTR. Secure Message is a simple encrypted messaging solution for the widest scope of applications. Use Secure Message to send encrypted and signed data from one user to another, from client to server, to prevent MITM attacks and avoid single secret leakage. Based on ECC + ECDSA / RSA + PSS + PKCS#7.

Hyenae is a highly flexible platform independent network packet generator. It allows you to reproduce several MITM, DoS and DDoS attack scenarios, comes with a clusterable remote daemon and an interactive attack assistant. *** Hyenae is back *** Hyenae will be continued here: https://sourceforge.net/p/hyenae-ng

ArpON (ARP handler inspection) is a Host-based solution that make the ARP standardized protocol secure in order to avoid the Man In The Middle (MITM) attack through the ARP spoofing, ARP cache poisoning or ARP poison routing attack.

CookieMonster that demonstrates HTTP session hijacking attacks. It sniff your network interface and hijack all cookie. The hijacked cookies can be edit and/or injected in your Firefox. It include a arp poisoning tool.

NetBox is a software programmed in C for testing vulnerabilities in the network. Using this software you can attack your network using a combination of differents known attacks (ARP or DNS Spoofing, MITM, ...) and detect bugs of security.

Netstorm is a highly flexible, fast and plattform independent network security and reliability tester which allows you to setup real world low level flood attack scenarios (such as MITM, DoS and DDoS) within a local area network and on the internet.

Application proxy toolkit which inherits the ideology of TIS fwtk and maintains API backwards compatibility. The design goal is to make it simple yet powerful; no performance hacks allowed in the code and library dependencies are reduced to minimum.

RTCP is a network man-in-the-middle service for protecting TCP, enabling fault-tolerant servers to recover their connections when restarting.

This penetration testing tool allows an auditor to intercept SSH connections. A patch applied to the OpenSSH v7.5p1 source code causes it to act as a proxy between the victim and their intended SSH server; all plaintext passwords and sessions are logged to disk. Of course, the victim's SSH client will complain that the server's key has changed. But because 99.99999% of the time this is caused by a legitimate action (OS re-install, configuration change, etc), many/most users will disregard the warning and continue on. NOTE: Only run the modified sshd_mitm in a VM or container! Ad-hoc edits were made to the OpenSSH sources in critical regions, with no regard to their security implications. Its not hard to imagine these edits introduce serious vulnerabilities.

Jacknsee is an educational network security tool. Its purpose is to teach students in computer science how basic hijacking techniques are used to corrupt a network. Two scenarios have been implemented: Man in the Middle and Denial of Service.

EtherMan: Ethernet Man In The Middle Attack Tool. It is capable of forcing traffic between two hosts to pass by a third party (MITM) and then redirected to its original destination again. This program is written for educational reasons, and I am not res
