Netcat: TCP/IP Swiss Army Knife
This section describes selected tools you can use to monitor your network’s components and its hosted traffic to gauges performance and detect potential problem areas. A decoded form of the data is either printed to standard output or written to a file. In addition, tshark is capable of detecting, reading, and writing the same capture files as those that are supported by Wireshark. Used without any options, tshark works similarly to the tcpdump command and also uses the same live capture file format, libpcap.

The command is designed to be a dependable back-end that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and investigation tool, since it can produce almost any kind of connection its user could need and has a number of built-in capabilities. Its list of features includes port scanning, transferring files, and port listening, and it can be used as a backdoor.
A netcat process is engaging in network activity on a Linux host. Netcat Searches indices from: now-6m (Date Math format, see also Additional look-back time).
As you will see throughout this book, a plethora of network security and hacker tools are at your disposal. In most cases, each tool is used to focus on a specific goal. For example, some tools gather information about a network and its hosts. Others are used directly to exploit a vulnerability. The most beneficial and well-used tools, however, are usually those that are multifunctional and appropriate for use in several different scenarios. Netcat and Cryptcat are such tools. Netcat writes and reads data over those connections until they are closed.
Others might not be able to see the possibilities through the command-line arguments detailed in the lengthy README file. Before you can learn to use it, though, you need to download and install it.
Netcat: The TCP/IP Swiss Army Knife
As well as these well-known tools, a program you almost certainly have come across is the relatively famous Netcat. Among its formidable feature set, the fantastically minute Netcat can be a random port-scanning hacking tool, a whitehat security tool, and a server or a client; it performs monitoring, supports tunnelling, and is a simple TCP proxy server on top of all that!
These days, it handles IPv6 as well as IPv4 beautifully. Its astounding versatility means that integrating it with scripts is a veritable piece of cake.

For more than a decade, the Nmap Project has been cataloguing the network security community’s favorite tools. In this site became much more dynamic, offering ratings, reviews, searching, sorting, and a new tool suggestion form. This site allows open source and commercial tools on any platform, except those tools that we maintain such as the Nmap Security Scanner , Ncat network connector , and Nping packet manipulator.
is a binary code analysis tool that helps identify common variants of certain prevailing vulnerabilities that can give rise to common.
JexBoss is written in the Python programming language using standard Python libraries. JexBoss is run from the command-line interface CLI and operated using a console interface. JexBoss was released as an open-source tool on GitHub in November This capability can help attackers customize their attacks against their target and exploit zero-day Java deserialization vulnerabilities. This is achieved by using one of the following mechanisms:. JBoss AS 7.
Legacy versions of JBoss AS particularly versions 6 and older have unpatched security vulnerabilities because they are no longer maintained. In March , the Cisco Talos Intelligence Group Talos investigated a widespread ransomware campaign known as SamSam, which was targeting the healthcare industry. The attackers then moved laterally to reach the intended ransomware targets. This campaign was the first widely reported use of JexBoss.

Knowing this will allow you to analyze other pieces of evidence, with the correct timestamps. Command: With netcat: Date | nc.
The information returned relating to these categories will only be as accurate as the data present in the RIR databases. The whois daemon acts like a standard whois server would, but with some added functionality. As a measure of speed, queries of approximately 10, IPs should return in less than a minute given a moderately sized Internet link.
IPs that are seen abusing the whois server with large numbers of individual queries instead of using the bulk netcat interface will be null routed. If at all possible you should consider using the DNS based query interface since it is much more efficient for individual queries. Note that this method of finding peers is FAR from perfect and not an exact science.
To use the command-line arguments on a single IP query, be sure to enclose the request in quotes and to have a space before the first argument so that your whois client will not try to interpret the flags locally. This is the same as gnetcat in FreeBSD ports. Add the word begin at the top of the file and the word end at the bottom. All DNS-based queries should be made by pre-pending the reversed octets of the IP address of interest to the appropriate zone listed above, demonstrated in the following examples:.
IPv6 queries are formed by reversing the nibbles of the address, and placing dots between each nibble, just like an IPv6 reverse DNS lookup, except against origin6. Note that you must pad out all omitted zeroes in the IPv6 address, so this can get quite long! For example, to look up b, you would issue the following query:.
You can considerably shorten your query if you assume that the long runs of zeroes are in the host portion of the address as is often the case with IPv6 addresses:.
