DNSChef alternatives

DNSteal allows you to extract files from a machine through DNS requests. This can be used to circumvent security measures and test them against data leakage. The tool supports compression and allows for multiple files to be transferred.

Although there are many port scanning utilities, sometimes it is specific functionality that makes a tool really powerful. For example, QuickScan saves the results of a scan, which then can be processed later for follow-up.

SubFinder is a tool to scan domains and discover subdomains. This may be useful during the reconnaissance phase of penetration testing where information is collected. Some subdomains may reveal sensitive data or point to interesting targets such as a backup location.

When a project requires resolving or guessing host names, then this tool is a great addition to the toolkit. It focuses on 'fast' by using asynchronous operations. The list of names to try is provided with a wordlist.

ArpOn protects a system by running as a daemon and guard against a Man in the Middle (MitM) attack due to ARP spoofing, cache poisoning, or an ARP poison routing attack.

The tool works by using three types of inspection to detect a related attack.

• SARPI (Static ARP Inspection), statically configured networks (without DHCP)
• DARPI (Dynamic ARP Inspection), dynamically configured networks (with DHCP)
• HARPI (Hybrid ARP Inspection), statically and dynamically configured networks (with DHCP)

BetterCAP is often used by those who perform penetration testing and security assessments. This tool and framework is in particular useful for attempting man-in-the-middle attacks (MitM).

This tool performs multiple types of scanning and attacks, which can be useful during penetration tests and security assignments.

This tool would most likely be used to intercept traffic during security assessments. Plaintext passwords and session data can be intercepted with it.

SSLsplit is a tool for man-in-the-middle attacks against SSL/TLS encrypted network connections. Connections are transparently intercepted through a network address translation engine and redirected to SSLsplit. SSLsplit terminates SSL/TLS and initiates a new SSL/TLS connection to the original destination address, while logging all data transmitted. SSLsplit is intended to be useful for network forensics and penetration testing.

SSLsplit supports plain TCP, plain SSL, HTTP and HTTPS connections over both IPv4 and IPv6. For SSL and HTTPS connections, SSLsplit generates and signs forged X509v3 certificates on-the-fly, based on the original server certificate subject DN and subjectAltName extension. SSLsplit fully supports Server Name Indication (SNI) and is able to work with RSA, DSA and ECDSA keys and DHE and ECDHE cipher suites. Depending on the version of OpenSSL, SSLsplit supports SSL 3.0, TLS 1.0, TLS 1.1 and TLS 1.2, and optionally SSL 2.0 as well. SSLsplit can also use existing certificates of which the private key is available, instead of generating forged ones. SSLsplit supports NULL-prefix CN certificates and can deny OCSP requests in a generic way. For HTTP and HTTPS connections, SSLsplit removes response headers for HPKP in order to prevent public key pinning, for HSTS to allow the user to accept untrusted certificates, and Alternate Protocols to prevent switching to QUIC/SPDY. As an experimental feature, SSLsplit supports STARTTLS mechanisms in a generic manner.

Sslcaudit is a tool that focuses on the niche of testing SSL/TLS clients.
