If these attacks are conducted against real-world systems, the company could easily lose revenue and customers. To prevent these kinds of losses, White Hats must be very selective of what they do and how they do it. Often, only the most delicate scans or attacks can be used against production machines, and the more aggressive scans are relegated to test networks, which often do not truly replicate the real world. This is assuming that the test network even exists. It is not uncommon to find production systems that are so costly that it is not economically feasible to make multiple purchases simply to have the test network. In those types of cases, it is very difficult for a White Hat to know the true extent of the systems vulnerability or exploitability. From a financial perspective, specializing in information security has been quite beneficial. Salaries have continued to rise because the federal requirements for auditing and security assessments have forced many companies to seek out individuals with the unique ability to conduct effective penetration tests. Long gone are the days when companies were content with basic Nessus scans, and nothing else. Today, security professionals are in demand, and companies realize that security isn’t simply a firewall or an antivirus software but a life cycle involving security policies, training, compliance, risk assessments, and infrastructure.
there are several ways to practice this step; the easiest way is to set up a vulner- able target in your penetration-testinglab. once again, using virtual machines is helpful because exploitation can be a very destructive process and resetting a virtual machine is often easier and faster than reimaging a physical machine. if you are new to exploitation, it is important that you have a few immedi- ate successes. this will keep you from getting discouraged as you progress and move onto more difficult targets where the exploitation process becomes more tedious and difficult. As a result it is suggested that you start learning exploi- tation by attacking old, unpatched versions of operating systems and software. successfully exploiting these systems should give you motivation to learn more. there are many examples of students becoming quickly and permanently dis- illusioned with exploitation and hacking because they attempted to attack the latest-greatest-fully-patched operating system and fell flat on their face. remember this book focuses on the basics. once you master the tools and tech- niques discussed here, you will be able to move onto the more advanced topics. if you are new to this process, let yourself win a little and enjoy the experience. if possible, you should try to obtain a legal copy of microsoft’s xP to add to your pen testinglab environment. You should be able to find a legal copy on fIGURE 4.24
The need for personal labs is high – even professionalpenetration testers set up small, personal labs at home to experiment on. There is a difference between a personal lab, and a professionallab that should be noted. A professionallab, even if maintained by an individual, can be used to identify and report on discovered vulnerabilities. For those readers who are interested in maintaining a professionallab, they should skip ahead to the section titled “Corporate Lab.” This section will focus on creating a small lab for personal use, where different hacking techniques can be learned and replicated, but a lot of security features are relaxed. The primary objective of personal labs is almost purely educational and often used to replicate or create exploits. This is different than corporate labs, which are used to exploit corporate assets.
Where do we see the usage of fuzzing today and tomorrow? IT decision makers at software companies should deploy negative testing because of the direct cost benefits and advantages associated with it. A flaw identified proactively before deployment has enormous value to them. Identifying specific protocol and permutations of inputs, software testers are able to determine difficult issues using this model-based optimized method. Additionally, they do not waste time trying to explore the infinite amount of inputs to determine the particular test that causes anomalous behavior. Negative testing solves this issue by allowing them to apply their previous experience with typical problem areas to target specific test cases, giving them more time to work on other higher-priority tasks. Negative testing also has benefits for the customer: code has fewer defects, so there is less public exposure to attacks and that makes for a better experience for the software end user. There are no false positives in fuzzing. Negative testing is just one piece of the puzzle of security testing techniques, and fuzzing is just one form of negative testing. But possibly it is the most cost effective form of security testing, depending how well you deploy it.
Unfortunately, it is common for organizations to consider network- and host-based security programs as sufﬁcient security. In reality, these types of focused programs are subsets of an information security program, dealing with the speciﬁc risks involved with the transport, processing, and storage of an organization’s information. A comprehensive security program must also consider, for example, physical security, including physical access controls and physical media handling procedures. Although much attention is traditionally lavished on logical controls such as ﬁrewalls and access lists, perceptive hackers are fully aware that information can potentially be obtained through activities such as dumpster diving. Every day conﬁdential printouts and unsanitized magnetic media are thrown out by unsuspecting organi- zations with stellar network security controls but marginal information security controls. Understanding not only the company’s digital assets and logical and phys- ical controls, the expected management of risk based on the security program provides a substantial supporting element to the employment of a penetration test. Another aspect often overlooked is the organization’s personnel. Typically, an organization will be very cognizant of education and experience requirements for personnel, and some industries may require varying degrees of background checks. This only establishes their credibility and suitability to perform their jobs, but does not address information security in any meaningful way. Unless the level or status of the employees is directly related to their roles with regard to information use, access, responsibility, and other security concerns related to digital assets, the role of the employee and the investigative employment process has little measurable support for information security.
Impact of testing scenarios. Furthermore, several participants reported that, beyond the feeling of autonomy, their experience was influenced by the testing situation in other ways. Many of them mentioned that they performed actions through the testing scenarios that they would not have performed at home because they usually are not using these kinds of systems this way. Sometimes the scenarios would lead to positive experiences; this was, for instance, the case for a participant who discovered nice shoes on Amazon though she generally would only look for books or computer material. But more often in this experiment, this led to frustration and negative experiences; for instance, when users had to modify settings on the camera (e.g., picture size, filter effects) and reported that they would only have used the Auto mode at home and would probably have been very satisfied with it:
As I began to teach, speak at conferences, and get involved in the security community, I felt that the industry could benefit from my lessons learned. This book is a collection of just that. One important thing I want to point out is that I am not a professional writer, but wrote this book as a hobby. You may have your own preferred tools, techniques and tactics that you utilize, but that is what makes this field great. There are often many different answers to the same question and I invite you to explore them all. I won’t be giving a step-by-step walkthrough of every type of attack; so it’s your job to continually do research, try differently methods, and see what works for you.
These goals of the penetration test were met. It was determined that a remote attacker would be able to penetrate Archmake’s defenses. To make this situation even worse, the initial attack vector can be discovered via automated scanning, creating a situation where a remote attack could be initiated on a non-‐targeted basis. The impact of this penetration led to the complete control of Archmake's information systems by the attacker.
Cette puissance de recherche peut tout aussi bien être utilisée par les pirates informatiques pour leur permettre d’obtenir des informations sensibles. On parle alors de « Google Hacking ». Ce terme désigne communément l’utilisation des nombreux opérateurs de recherches disponibles avec des mots clés ou des phrases judicieusement choisies pour obtenir des informations sensibles de toute nature (fichiers de configuration, version des logiciels utilisés, données personnelles, numéro de cartes bleues, …). La récupération de telles informations peut alors constituer une première étape dans le cas de tests d’intrusion … où d’attaques réelles !
In summary, Kali linux feels a lot smoother to work with than BackTrack, whilst most of the tools remain fairly similar or unchanged; the main overhaul to be commended on is the over- all improvement in the quality of the distribution from the move to Debian. It now feels like a com- plete distribution with far less flakiness and a lot more stability. For a duck dive into the pen-test tools which ship with Kali, I would recommend doing Offensive Security’s PenetrationTesting with BackTrack(PWB) course which will familiar- ise you with all the tools necessary to conducting a complete penetration test with reporting. The main advantage you will notice is that the tools are now all in path with Kali. The only advice I have in pursuing this course is to get permission from your other half, as it will take a good couple of months out of your life, but is extremely fun, ad- dictive, and rewarding with all the breakthroughs you will have. Well done to the Offensive Security Team for creating such an improved distribution, and good luck with your Kali experience.
There are various reasons for hacking. When most of us hear hacker we think about com- puter and network security, but lawyers, salesmen, and policemen are also hackers at heart. It’s really a state of mind and a way of thinking rather than a physical attribute. Why do people hack? There are a couple of motivators, but one specific reason is to be able to know things that the ordinary man on the street doesn’t. From this flow many of the other motiva- tors. Knowledge is power—there’s a rush to seeing what others are doing without them knowing it. Understanding that the thirst for knowledge is central to hacking, consider Google, a massively distributed super computer, with access to all known information and with a deceivingly simple user interface, just waiting to answer any query within seconds. It is almost as if Google was made for hackers.
n poco como dedicación a los tiempos pasa- dos, hoy vamos a hacer un breve recordatorio desde las primeras épocas de los sistemas te- lefónicos e informáticos hasta la fecha de hoy sobre los actos más importantes que han sucedido acerca del mundo de la informática y el underground, y daremos unas escuetas descripciones a ciertos grupos de personas que han quedado enmarcados en nuestra memoria por sus diferentes actividades en el mundo del hacking.

Microsoft posee una extensa lista de sistemas operativos. Está aún en producción la familia 2000 en todas sus variedades, la 2003 y la más reciente 2008. A éstos, se les suman XP y Vista como terminales en general; y no olvidemos los obsoletos 98/ME que perduran en funcionamiento en muchas organizaciones e instituciones del continente y del mundo. No malgastaremos las páginas de este capítulo desen- trañando la arquitectura de cada uno de estos sistemas operativos, sino que hare- mos foco en los aspectos más interesantes, técnicas y herramientas relacionadas que hoy en día son utilizados en el hacking ético. Microsoft Windows es, en la ac- tualidad, el sistema operativo más utilizado por las organizaciones y, de su masivi- dad, surge el interés o la casualidad de que sea víctima del embate de los atacantes. Recordemos que lo desarrollado a continuación pertenece a una de las últimas etapas en un chequeo ético: la del ataque o penetración. Un intruso, luego de haber investigado en internet, enumerado, analizado resultados y escaneado de modo agresivo (etapas anterio- res al embate final o penetración) logró, dentro de nuestro servidor Windows, conseguir un prompt MS-DOS para ejecutar comandos y dumpear el contenido del SAM.
2000, news sources reported an attack against Microsoft's internal systems, targeting its source code. In May 1999, the FBI investigated several hacking groups based in the United States. After the FBI seized a suspected teenage hacker's computer, several hacker groups retaliated by defacing government Web sites. At one point, a DoS attack caused the FBI Web site to be taken offline for seven days.  In January 2000, an Internet hacker threatened CD Universe, stating that if the company did not pay a ransom of $100,000 he would publish 300,000 credit card numbers he stole from its Web site. The company refused to pay the ransom and the hacker published over 25,000 credit card numbers. This attack destroyed consumer confidence in CD Universe and added to the mistrust consumers already have in online buying. Between the middle of 1999 and the beginning of 2000, computer viruses such as Melissa, I LOVE YOU, and Explorer.zip devastated corporate networks, forcing companies to shut down for days to combat the viruses. These viruses demonstrated the frailty of present-day virus scanners and how easy it is to get users to execute malicious code. The incidents also illustrated the problems and losses a company can suffer from an attack.
