Sippts is a set of tools to audit VoIP servers and devices using SIP protocol. It is programmed in Python script and it allows us to check the security of a VoIP server using SIP protocol, over UDP, TCP and TLS protocols.
3ede5028958a1effbe95fce1926ba0492f4dc037dcfa74011730bc24129aa41bGNUnet is a peer-to-peer framework with focus on providing security. All peer-to-peer messages in the network are confidential and authenticated. The framework provides a transport abstraction layer and can currently encapsulate the network traffic in UDP (IPv4 and IPv6), TCP (IPv4 and IPv6), HTTP, or SMTP messages. GNUnet supports accounting to provide contributing nodes with better service. The primary service build on top of the framework is anonymous file sharing.

8a744ff7a95d1e83215cce118050640f6c12261abe4c60a56bcf88e500f0023dNmap is a utility for port scanning large networks, although it works fine for single hosts. Sometimes you need speed, other times you may need stealth. In some cases, bypassing firewalls may be required. Not to mention the fact that you may want to scan different protocols (UDP, TCP, ICMP, etc.). Nmap supports Vanilla TCP connect() scanning, TCP SYN (half open) scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy (bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses some packet filters), TCP ACK and Window scanning, UDP raw ICMP port unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Direct (non portmapper) RPC scanning, Remote OS Identification by TCP/IP Fingerprinting, and Reverse-ident scanning. Nmap also supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings.

A remote attacker could use this to facilitate attacks on UDP based services that depend on source port randomization. It was discovered that the Bluetooth subsystem in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

35d0283a24cb4d861e2191d597f6e9cd041aa7cda3233d7f76da6fbd4f2158e1nullscan is a modular framework designed to chain and automate security tests. It parses target definitions from the command line and runs corresponding modules and their nullscan-tools afterwards. It can also take hosts and start nmap first in order to perform a basic portscan and run the modules afterwards. Also, nullscan can parse a given nmap logfile for open tcp and udp ports and again run the modules afterwards. All results will be logged in specified directories with a clean structure and an HTML report can subsequently be generated.
