My book reviews Updated: July 8, Recently, I've been doing a handful of book reviews, which I find to be a great honor and quite a bit of fun. Now, as one of the publishers wisely noted, having a dedicated book review page should allow readers to more easily find the content otherwise scattered across individual articles. Indeed, this is a very good idea. So here we are. This page is a compilation of my book reviews, with a teaser screenshot and a few paragraphs of text. New reviews will be added when written and published, so you might want to come by and take a look once in a while, I hope you will find this resource useful, and if you have any ideas, feel free to ping me. This was an interesting offer. On one hand, I'm well familiar with Linux security. On the other, I have used BackTrack 4 in the past.

Additionally, it will also point out several exploit repositories that should keep you informed about the publicly available exploits and when to use them.

You will also learn to use one of the infamous exploitation toolkits from a target evaluation perspective. Moreover, you will discover the steps for writing a simple exploit module for the Metasploit framework.

Chapter 10, Privilege Escalation, introduces you to privilege escalation as well as network sniffing and spoofing. You will learn how to escalate your gained privilege using a local exploit. You will also learn the tools required to attack a password via the offline or online technique. You will also learn about several tools that can be used to spoof the network traffic. In the last part of this chapter, you will discover several tools that can be used to do a network sniffing attack.

You will learn about several backdoors that are available and how to use them. You will also learn about several network tunneling tools that can be used to create covert communication between the attacker and the victim machine. Chapter 12, Documentation and Reporting, covers the penetration testing directives for documentation, report preparation, and presentation.

These directives draw a systematic, structured, and consistent way to develop the test report. Furthermore, you will learn about the process of results verification, types of reports, presentation guidelines, and the post-testing procedures. Appendix A, Supplementary Tools, describes several additional tools that can be used for the penetration testing job.

Appendix B, Key Resources, explains various key resources to help you become more skillful in the penetration testing field.. We will describe the definition and purpose of information gathering. We will also describe several tools in Kali Linux that can be used for information gathering.

After reading this chapter, we hope that the reader will have a better understanding of the information gathering phase and will be able to do information gathering during penetration testing.

Information gathering is the second phase in our penetration testing process Kali Linux testing process as explained in the Kali Linux testing methodology section in Chapter 2, Penetration Testing Methodology. In this phase, we try to collect as much information as we can about the target, for example, information about the Domain Name System DNS hostnames, IP addresses, technologies and configuration used, username's organization, documents, application code, password reset information, contact information, and so on.

During information gathering, every piece of information gathered is considered important.

Information gathering can be categorized in two ways based on the method used: active information gathering and passive information gathering. In the active information gathering method, we collect information by introducing network traffic to the target network. While, in the passive information gathering method, we gather information about a target network by utilizing a third-party's services, such as the Google search engine. We will cover this later on.

Remember that no method is better in comparison to the other; each has its own advantage. In passive scanning, you gather less information but your action will be stealthy; while, in active scanning, you get more information but some devices may catch your action. During a penetration testing project, this phase may be done several times for the completeness of information collected.

You may also discuss with your pen-testing customer, which method they want. We will discuss the following topics in this chapter: Public websites that can be used to collect information about the target domain Domain registration information DNS analysis Route information Search engine utilization Using public resources On the Internet, there are several public resources that can be used to collect information regarding a target domain.

The benefit of using these resources is that your network traffic is not sent to the target domain directly, so our activities are not recorded in the target domain logfiles. The following are the resources that can be used: No. Resource URL Description 10 This is a free search engine that allows you to find people by their name, phone number, and address TinEye is a reverse image search engine. We can use TinEye to find out where the image came from, how it is being used, whether modified versions of the image exist, or to find higher resolution versions shtml This can be used to search for information regarding public listed companies in the Securities and Exchange Commission.

Due to the ease of use, you only need an Internet connection and a web browser, we suggest that you utilize these public resources first before using the tools provided with Kali Linux. To protect a domain from being abused, we have changed the domain name that we used in our examples. We are going to use several domain names, such as example.

Querying the domain registration information After you know the target domain name, the first thing you would want to do is query the Whois database about that domain to look for the domain registration information.

The Whois database will give information about the DNS server and the contact information of a domain. To find out the Whois information for a domain, just type the following command: whois example. Go to net for detailed information. COM Whois Server: whois. In most cases, registrar. The Registrant: Jalan Sudirman No. COM NS2. This information will be useful at the later stages of penetration testing. Besides using the command-line whois client, the Whois information can also be collected via the following websites, which provide the whois client: Or, you can also go to the top-level domain registrar for the corresponding domain: America: Europe: Asia-Pacific: Beware, that to use the top-level domain registrar whois, the domain needs to be registered through their own system.

After getting information from the Whois database, next we want to gather information about the DNS entries of the target domain. It is used as an alias name for another canonical domain name. For example, in a penetration test engagement, the customer may ask you to find out all of the hosts and IP addresses available for their domain. The only information you have is the organization's domain name. We will look at several common tools that can help you if you encounter this situation.

To help us out on this matter, we can use the following host commandline tool to lookup the IP address of a host from a DNS server: host The following is the command's result: has address has IPv6 address Looking at the result, we know the IPv4 and IPv6 addresses of the host www. To query for any records, just give the -a option to the command. If you give the domain name as the command-line option in host, the method is called forward lookup, but if you give an IP address as the command-line option to the host command, the method is called reverse lookup.

Try to do a reverse lookup of the following IP address: host What information can you get from this command? The host tool can also be used to do a DNS zone transfer. With this mechanism, we can collect information about the available hostnames in a domain. Without this mechanism, the administrators have to update each DNS server separately. Due to the nature of information that can be gathered by a DNS zone transfer, nowadays, it is very rare to find a DNS server that allows zone transfer to an arbitrary zone transfer request.

If you find a DNS server that allows zone transfer without limiting who is able to do it, this means that the DNS server has been configured incorrectly. In this case, the misconfigured DNS server is ns4. The advantages of dig compared to host are its flexibility and clarity of output. With dig, you can ask the system to process a list of lookup requests from a file. Let's use dig to interrogate the example. To request for any other DNS record type, we can give the type option in the command line: dig example.

To do zone transfer using dig, we must set the authoritative DNS server for that domain and set axfr as the type: example. Based on this, we can be confident about the DNS records collected. The DNS information that can be gathered is as follows: The host IP addresses The DNS server of a domain The MX record of a domain In this chapter, you may see that we used several tools that generate similar results, this is because we need to validate the information collected.

If the information is found in more than one tool, we can be more confident with the information. Besides being used to get DNS information, dnsenum also has the following features: Get additional names and subdomains utilizing the Google search engine.

Find out subdomain names by brute forcing the names from the text files. The dnsenum tool included in Kali Linux comes with a dns. Carry out Whois queries on C-class domain network ranges and calculate its network ranges.

Carry out reverse lookup on network ranges. Use threads to process different queries. As an example of the dnsenum tool usage, we will use dnsenum to get DNS information from a target domain. The command to do this is as follows: dnsenum example. Using the default options of dnsenum, we can get information about the host address, name servers, and the mail server's IP address.

Fortunately, the ns1. In the case that the zone transfer is not successful, we can do brute forcing of the lookups to find the subdomains from a wordlist. For example, if we want to brute force the subdomain using the provided text file wordlist dns. Luckily for us, the target domain uses common subdomain names. See if you have enough points for this item.
