WireBug is a tool set for Voice-over-IP penetration testing. It is designed as a wizard which makes it easy to use. The tools are build for single using too, so every tool is its own python or bash program.

Install the dependencies in requirements.txt and the python dependencies in requirements_python.txt. If you have problems with installation of netfilterqueue, you can build it from source:

pip install -U git+https://github.com/kti/python-netfilterqueue.git

Use the configure.sh script to download and build Cisco Systems' SRTP library.

• FullBridge: This is a simple bash script to set up a layer2 bridge with two defined interfaces.
• BridgeTrap: This script is useful in combination of the FullBridge tool. It will mirror the traffic of the bridge to a defined interface e.g. a raspberry pi with two interfaces for bridging and one as monitoring.
• DoubleEncapsulation: This python program will craft a double encapsulated ICMP packet and send it to the destination - possible VLAN Hopping.
• TimeShift: Tool for response to a NTP request in a man-in-the-middle position (also with FullBridge) with a timestamp in the past or future. You can easily check if the client (VoIP Phone) checks the validity of the server certificate (SIPS, H.323s, HTTPS, LDAPS etc.), or simply use it as a DOS Tool.
• VlanEnum: This bash script creates 802.1Q virtual interfaces with VLAN tagging and waiting for possible DHCP responses. If it was possible to get an IP Address the interface will be staid alive otherwise it will be deleted.
• SaCLaC: This includes two python programs. One for spoofing fake LLDP-MED packets to getting into VoIP VLAN or trigger a DoS by instruct the client to set a VLAN-Tag and one to analyze CDP Information of a PCAP File.
• DecodeSRTP: This script makes it easy to use the Cisco Systems' SRTP library for decrypting a SRTP-SDES Stream if the AES-Key was extracted from the signalling part.
• SIPCraft: This tool is delivered with some basic SIP messages (REGISTER, OPTIONS, INVITE, BYE) but it is also for crafting your own SIP message by using the option "--individual". With this option it is possible to store your SIP content in a simple text file and then spoof it with the sip craft tool. The script supports TCP and UDP.
• CrackTheSIP: A simple brute force tool for cracking SIP digest authentication by using a word list.
• ZRTPDowngrade: A Tool to drop ZRTP initiated Packets in a man-in-the-middle position.
• EvilSTUN: A simple tool for fake STUN responses.
• SIPFuzz: A tool for SIP fuzzing.
• SIPEnum: This tool enumerates SIP extensions by a given file.
• SIPBrute: A tool for online brute force attacks against SIP proxies.
• RTPFuzz: A tool for fuzzing an injecting random RTP packets (noise) into running streams.

The goal of the WireBug tool set is the wizard with tab-completion. This makes it easy to use without knowledge of detailed information about the tool or options. It is recommended to use the tools with the wizard.
