Tool for auditing telephone systems
WarVOX is a suite of tools for exploring, classifying, and auditing telephone systems. Unlike normal wardialing tools, WarVOX works with the actual audio from each call and does not use a modem directly. This model allows WarVOX to find and classify a wide range of interesting lines, including modems, faxes, voice mail boxes, PBXs, loops, dial tones, IVRs, and forwarders. WarVOX provides the unique ability to classify all telephone lines in a given range, not just those connected to modems, allowing for a comprehensive audit of a telephone system.
WarVOX requires no telephony hardware and is massively scalable by leveraging Internet-based VoIP providers. A single instance of WarVOX on a residential broadband connection, with a typical VoIP account, can scan over 1,000 numbers per hour. The speed of WarVOX is limited only by downstream bandwidth and the limitations of the VoIP service. Using two providers with over 40 concurrent lines we have been able to scan entire 10,000 number prefixes within 3 hours.
The resulting call audio can be used to extract a list of modems that can be fed into a standard modem-based wardialing application for fingerprinting and banner collection. One of the great things about the WarVOX model is that once the data has been gathered, it is archived and available for re-analysis as new signatures, plugins, and tools are developed. The current release of WarVOX (1.0.0) is able to automatically detect modems, faxes, silence, voice mail boxes, dial tones, and voices.

Information Warfare Classification according to Schwartau
"Information Warfare: Cyberterrorism: Protecting Your Personal Security in the Electronic Age" by Schwartau
According to Schwartau, information warfare can be divided into three areas:
>> Class 1: Personal Information Warfare, where the individual is the target. It is also called Identity Theft.
>> Class 2: Corporate Information Warfare, or “the rough equivalent of what we used to call industrial espionage". It involves “patents, copyrights, business deals—that is, the real value of companies”.
>> Class 3: Government Information Warfare. The Russia-Georgia conflict is an example of this. Another example is a similar situation that developed in Estonia last year, where that former Soviet satellite’s cyber infrastructure was compromised by DoS attacks over several days after Estonian officials removed a Russian war memorial from the center of the capitol.

Configuring Network in Linux
1. DHCP Environment:
Using DHCP Client Daemon
# dhcpcd
Eg: # dhcpcd eth0
where interface is eth0, default Ethernet (LAN) Card interface.
2. Static IP Assigning:
# ifconfig netmask
# route add default gw dev
# echo "nameserver" > /etc/resolv.conf
Eg: Static ip = 192.168.0.12; subnet = 255.255.255.0
gateway = 192.168.0.1; primary dns server = 192.168.0.2
# ifconfig eth0 192.168.0.12 netmask 255.255.255.0
# route add default gw 192.168.0.1 dev eth0
# echo "nameserver 192.168.0.2" > /etc/resolv.conf
The first command assigns an IP address to the interface.
The second command adds the route information, so the system can reach other machines. It adds the default gateway for the packets to get routed to a gateway system. This command can be replaced by a more specific command
# route add -net 192.168.0.0 netmask 255.255.255.0 gw 192.168.0.1 dev eth0
This adds a route to all packets to network 192.168.0.0 to go through interface eth0 to gateway 192.168.0.1 for gettting routed to their destination.
The third command adds the DNS server IP to resolv.conf. Whenever a request comes for any DNS name resolution, resolv.conf is checked for the DNS servers to query the information.
3. Verification:
# ifconfig | grep inet
# ping -c 2 www.google.com
The first command gives the IP address assigned.
The second command can be used to verify the route and dns working.
If there is positive response from the ping, then the network settings are complete.
Else try to ping to another system in the same network. If this is positive, then there might be a problem reaching DNS server and need to be checked. If this is negative, then routing information needs to be checked. "route -v" gives the routing information required.
