Now this is a tricky one. You may have read it in countless comparisons and on numerous blogs that Macintosh operating systems are the least secure ones out there, especially when pitted against the vastly more popular Windows operating systems. But here, the very popularity of Windows works against it. Don't get it? Well here is the thing, Very few hackers target Macintosh systems because of the fact that a large majority of people do not use it. Take advantage of this and switch to Macintosh operating systems. And do not forget the fact that there is no operating system in the world which is completely hack-proof.

Python Network Hacking Essentials by Earnest Wish 2015 pdf

Password Cracking repeatedly enters the username and password to find the authentication information. This has the disadvantage in that it takes a lot of time to seize the password. Also, if no password matches the data dictionary, it is possible to fail the attack. On the other hand, data that is transmitted over a TCP/IP network can be seized in transit. Let's assume that you have been able to convert a PC in an enterprise's internal network into a zombie through successful penetration testing. The TCP/IP 2-layer protocol primarily uses the broadcast protocol, and therefore, once the intranet has been accessed, it is possible to see all packets that have been sent from the internal network.

Python Web Hacking Essentials by Earnest Wish   2015 pdf

Python Web Hacking Essentials by Earnest Wish 2015 pdf

Most of the services you are using operate over the Internet. In particular, web pages transmitted over the HTTP protocol may be at the heart of an Internet service. A home page that is used for a PC and a smartphone is a kind of Web service. Most companies basically block all service ports due to security, but port 80 remains open for Web services. Google, which is a typical portal site that people connect to everyday, also uses port 80. Web services recognize that you are using the port 80, if you do not specify a different port behind the URL. Through port 80, a web server transmits a variety of data to your PC, including text, images, files, videos. Through the port 80, a user can also transmit a variety of data from text to a large file to a web server.

163 The Basics Of Hacking And Penetration Testing [ PUNISHER ] pdf

when not spending time with my family, there are two things i enjoy doing: reading and hacking. most of the time, i combine these hobbies by reading about hacking. As a professor and a penetration tester, you can imagine that my bookshelf is lined with many books on hacking, security, and penetration test- ing. As with most things in life, the quality and value of every book is different. some books are excellent resources that have been used so many times that the bindings are literally falling apart. others are less helpful and remain in nearly new condition. A book that does a good job of explaining the details without losing the reader is worth its weight in gold. Unfortunately, most of my per- sonal favorites, those that are worn and tattered, are either very lengthy (500 pages) or very focused (an in-depth guide to a single topic). neither of these is a bad thing; in fact, quite the opposite, it is the level of detail and the clarity of the authors’ explanation that make them so great. But at the same time, a very large tome focused on a detailed subject of security can seem overwhelming to newcomers.

Professional Penetration Testing  Creating and Operating a Formal Hacking Lab pdf

Professional Penetration Testing Creating and Operating a Formal Hacking Lab pdf

Penetration testers with a network architecture background can identify deficiencies in a large variety of network designs, as well as the placement of elements within those designs. Deficiencies can involve different communication protocols used within the network as well as devices used to deliver and protect the communication traffic. Recently, there has been a greater need for penetration testers familiar with networks. Now that companies have finally recognized the value of information security (okay, maybe I’m exhibiting Pollyannaism by saying that), processes are in place to analyze applications and systems regularly, including corporate scanning and third-party audits. However, the networks have been neglected, often because of the misplaced belief that has been around for years that firewalls and intrusion detection systems (IDSes) are effective tools, simply because of their presence in the network. The reality is that these network appliances are simply “speed bumps,” and network devices and communication protocols are just as easy, if not easier, to exploit as applications and operating systems, depending on the skill of the network administrators. Like anything in information security, an appliance’s security is directly related to the knowledge possessed and effort put forth by those who configure and maintain the appliances.

The Ethical Hack   A Framework for Business Value Penetration Testing pdf

The Ethical Hack A Framework for Business Value Penetration Testing pdf

Finally, information having nothing to do with the engagement may be saved by the consultant on her system. Data may be from previous engagements, e-mail communications, employment data, or anything else that someone would want to keep on a computer. An attacking system should be devoid of personalized data that could be used to identify the tester, or used against the consultant (or her company) or previous customers in any way. It is all too often that a system is compromised by a hacker, Trojan, or virus possibly resulting in exposure of sensitive information. One example is a consultant that modified her laptop to perform penetration tests. Ironically, this is necessary for many because a dedicated “hacking system” is not provided by many firms. When she traveled from engagement to engagement (as many consultants do), she gained access to the corporate network through a VPN. Her computer was loaded with hacker tools of all types, some installed, others lying dormant waiting to be used. One of the tools installed included a basic keyboard-capturing program that after a few days would quietly send the recorded keystrokes to the hacker. Because the VPN was accessed daily, the hacker had all the information needed to gain access to the corporate network and her laptop. It wasn’t until several days later the activity was discovered and her passwords changed. But there is still no clear way to identify what the hacker could have accomplished with her stolen privileges and access to previous customer information. There are several options to a tester to limit exposure. Following is a list of common practices:

Hack IT Security Through Penetration Testing pdf

Hack IT Security Through Penetration Testing pdf

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. [5] 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.

Analysis of Various tools of Penetration Testing Harshdeep Singh 1, Jaswinder Singh2

The study has given the conclusion about the usability of the network penetration techniques that how effectively they can help in identifying the possible number of threats to the security system of the company and the possible ways in which they can be removed or eliminated. It is a significant method that can help in stopping any kind of hacking related to the theft of important data, information of the organization, or any other theft related to funds or money. The possible ways and methods which are used in this technique take out a keen observation on all the aspects of collecting previously recorded data to threat verification and proving the solution to the vulnerabilities and increasing the efficiency of the system. In this research, we used Kali Linux Operating System as it provides many security based tools that can help in performing penetration testing. Also, it provides various other tools that can be used in protecting the system from vulnerabilities. This research used tools from Kali Linus OS and then applied on a created framework to provide a proper technique(s) to protect the

Getting back to handling our Nmap scan results. As a penetration tester, the problem with scanning large ranges is organizing that data and identifying which low hanging fruit you want to attack first. You might identify that there are 100+ web sites within a range and to manually visit them becomes both time consuming and might not result in any type of vulnerability. Many times, a majority of web application pages are pretty useless and could easily be removed from manual review. Peeping Tom is a tool that will process an input of IPs and ports, take a screenshot of all HTTP(s) services, and present it in an easy to read format.

Xbox hack pdf

Xbox hack pdf

It has recently been called to the author’s attention that the hardware initialization pro- cedure of the Xbox contains a significant weakness. [17] Recall from section 2 that the first step in the Xbox boot process is to load the “jam tables” that configure the console’s chipsets. This jam table initialization procedure involves a lengthy and com- plex sequence of writes to various memory-mapped hardware register locations. As a result, the initialization procedure is implemented using a simple bytecode interpreter that reads initialization commands and data from the FLASH ROM. These bytecode commands–stored as plaintext–can be manipulated to cause the initialization procedure to abort before the kernel decryption/verification routine is executed, and to instead run insecure code directly out of the FLASH ROM. In other words, with plaintext-only modifications in the FLASH ROM, one can entirely bypass the Xbox’s security mech- anism. One could easily fix this security hole, however, by verifying the jam table’s contents prior to bytecode execution with a one-way hash function, or by explicitly coding all initialization functions within the secure boot block. Both of these solutions, however, would require the secure boot block to grow significantly from its current 512-byte size, and neither solution allows easy changes to the initialization procedure in case a bug is found or in case the hardware evolves as a result of cost reduction efforts.

Hacking Exposed Linux Linux Security Secrets & Solutions, 3rd Ed pdf

Adrian looked back down at his computer screen and giggled again. He knew that it had been just a matter of time before they would get hacked. He never considered that any of the compliance audits were any good. He always wondered how good a regulation could be if it requires running antivirus software on the Linux servers too? As terrible as the attack was he did feel that justice had been served. He had told them to put in more process controls. He had told them they had to encrypt the information and not just the transactions. He had told them they needed to tighten the authentication schemes to ensure that nobody could deny any part of any interactivity they had with the systems. He had told them they had to make sure the security auditors used the OSSTMM to measure their protection levels to indemnify themselves properly against attacks. He had told them all this time and again. Furthermore, he had argued that compliance to a generalized and watered-down regulation could not possibly be security fit for a bank. At the time, their dismissive attitude was perplexing to him.

86 Hardware Hacking Have Fun While Voiding Your Warranty [ PUNISHER ] pdf

However, this kind of sociopathy is probably not the real drive behind the renaissance of hardware hacking. I feel that the larger impetus is the recent pertinence of reverse-engineering consumer hardware. Rather than looking to hardware hackers for new product innovation, the public is looking to hard- ware hackers for the extension and liberation of existing solutions.This trend is a result of the tension between corporate motivations and the public’s desires. Corporations are motivated by profit; thus, accessories are expensive, feature sets are artificially limited to create price discrimination, and lately, hardware vendors are locking their products to particular brands of consum- able goods via embedded security or ID chips. On the other hand, consumers desire featureful, inexpensive products that deliver exactly what the they need, with no hidden costs or accessories required.

Google began its life as a college project called BackRub, written by founders Larry Page and Sergey Brin at Stanford University. While at Stanford, the young Googlers perfected their ideas and developed the basic tenets their multi-billion dollar company would later be built upon. One of these ideas was to use many low-end computers rather than high-end servers to run their search engine. Initially Larry Page and Sergey Brin had thought to license their technology out to other existing companies. Luckily for them, they didn’t find any takers. Yahoo! Founder David Filo suggested they start their own search engine company, so in early September 1998, they did just that. Google.com was launched to great success on September 7 th , quickly handling 10,000 queries a

Wardriving & Wireless Penetration Testing pdf

Wardriving & Wireless Penetration Testing pdf

Many of the concepts for penetration testing wireless networks are the same as those for wired networks. One major difference is that with a wired network, you gener- ally have a defined target IP range, or, if the test is internal, plug into an Ethernet port on your target’s network. With wireless penetration tests, organizations often want you to locate or identify their network prior to beginning the test, in order to simulate what a real attacker that was targeting their network could do. On some engagements, you will be provided with the Extended Service Set Identifier (ESSID) of the wireless network and/or MAC addresses of the access points your target has deployed. In these cases, identification is relatively simple. On the other hand, if you are expected to identify the network, this can be much more difficult.

Firewalls And Networks How To Hack Into Remote Computers pdf

Firewalls And Networks How To Hack Into Remote Computers pdf

The appropriate way for a system administrator to protect a system from this attack is to closely follow security advisories from vendors, CIAC, and CERT, and install patches as they become available. Careful configuration and setup can help to minimize potential vulnerabili- ties. If a hole exists that permits the user to act as root, the intruder can possibly still be caught by tracks left in utmp/wtmp. (All currently logged in users are listed in the utmp file. A history of all logins and logouts are transferred from the utmp file to the wtmp file. The “last” command will format the wtmp file and provide a complete listing of all logins, including information on the source of the login and the duration of the login.) However, not all programs leave entries in the utmp/wtmp files: remsh/rsh execute commands on the remote system without making any entry into the utmp/wtmp file. The syslog files are also extremely useful in monitoring system activity. Security monitoring programs exist that offer additional tracking capabilities.

Ethical Hacking Techniques with Penetration Testing

Ethical Hacking Techniques with Penetration Testing

would attempt to break into their systems and would identify, if there are any intrusion threats. These professionals, termed as “Red teams” or “ethical hackers”, follow same steps and tools as that of malicious hackers, but the difference is of there intensions. Ethical hackers have clear intensions to break computer security to save the organization from intrusion attacks. They never reveal the facts and information about the organization. But at any moment of time, if there intensions get sidetracked; they would be the one who would harm the most. This method of recognizing any intrusions into the network and systems was also used by United States Air Force. They conducted a “security evaluation” of the Multics operating systems for a two-level (secret/top secret) system. Their evaluation found that while Multics was significantly better than other conventional systems, it also had loopholes in hardware, software and procedural security. .The hackers performed various penetration tests[4] such as information-gathering, to identify any threat that might damage its integrity.

Don’t get me wrong — the UNIX-based tools are excellent at what they do. Programs such as Kismet (www.kismetwireless.net) and Wellenreiter (http://sourceforge.net/projects/wellenreiter/) offer many fea- tures that most Windows-based applications don’t have. These programs run really well if you have all the Linux dependencies installed. They also offer many features that you don’t need when assessing the security of your WLAN. If you want the power of the security tools that run on Linux, but you’re not interested in installing and learning much about Linux or don’t have the time to download and set up many of its popular security tools, I highly recom- mend you check out BackTrack (www.remote-exploit.org/backtrack. html). The bootable Slackware Linux-based CD “automagically” detects your hardware settings and comes with a slew of security tools that are relatively easy to use. Alternative bootable (or “live”) CDs include the Fedora Linux- based Network Security Toolkit (www.networksecuritytoolkit.org) and the Knoppix Linux-based Security Tools Distribution (http://s-t-d.org). A complete listing of live bootable Linux toolkits is at www.livecdlist.com. Having said this about UNIX-based tools, the good thing is that in the past couple of years, Windows-based tools have greatly improved — especially the commercial tools.
