How are passwords stored in Linux (Understanding hashing with shadow utils) A user account with a corresponding password for that account, is the primary mechanism that can be used for getting access to a Linux machine. Its very much logical to think that the passwords of all the user's in a system must first be saved in some kind of a file or a database, so that it can be verified during a user login attempt. And you do not require the skill set and expertise of a computer security scientist to think rationally that if you get hold of that database or file, which stores all the passwords, you can easily get access to the machine. John the Ripper password cracker John the Ripper is free and Open Source software, distributed primarily in source code form. If you would rather use a commercial product, please consider John the Ripper Pro, which is distributed primarily in the form of "native" packages for the target operating systems and in general is meant to be easier to install and use while delivering optimal performance. To verify authenticity and integrity of your John the Ripper downloads, please use our GnuPG public key.
XSS Filter Evasion Cheat Sheet Last revision (mm/dd/yy): 07/4/2018 This cheat sheet lists a series of XSS attacks that can be used to bypass certain XSS defensive filters. Please note that input filtering is an incomplete defense for XSS which these tests can be used to illustrate. Basic XSS Test Without Filter Evasion Google Dorks To Find Vulnerable Wordpress Sites - HackingVision Using Google Dorks To Find Vulnerable WordPress Sites WordPress is one of the most popular blogging applications in the world and its easy to install. This can make WordPress a prime target for those wanting to collect compromised hosting accounts for serving malicious content, spamming, phishing sites, proxies, rouge VPN’s, C&C servers and web shells.
Download the Free Nmap Security Scanner for Linux/Mac/Windows Nmap and Zenmap (the graphical front end) are available in several versions and formats. Recent source releases and binary packages are described below. Older version (and sometimes newer test releases) are available from the dist directory (and really old ones are in dist-old). For the more security-paranoid (smart) users, GPG detached signatures and SHA-1 hashes for each release are available in the sigs directory (verification instructions).
Archives Approximately 1 year ago today, Tim Tomes and I did a presentation on Volume Shadow Copies (VSC) at Hack3rCon II. Hack3rCon^3 just wrapped up, and I’ve officially been shamed into finally publishing the details of the research. Many of the faithful PDC readers will know most of these details, as some of them were included as pieces to posts on other topics, but I will try to provide a little something new. Volume Shadow Copies The Volume Shadow Copy Service (VSS) maintains copies of every 16k block that is changed on an NTFS disk. Then at certain times it packages up all those 16k blocks and puts them up into a Volume Shadow Copy (VSC). The times aren’t strictly predictable, but by default it will create a VSC automatically with the installation of new software and patches.
Near Field Communication (NFC) Technology, Vulnerabilities and Principal Attack Schema - Infosec Resources The Near Field Communication (NFC) is a set of standards for mobile devices designed to establish radio communication with each other by being touched together or brought within a short distance. The NFC standard regulates a radio technology that allows two devices to communicate when they are in close proximity, usually no more than a few centimeters, allowing the secure exchange of information. NFC standards are based on different communications protocols and data exchange formats, and include also existing radio-frequency identification (RFID) standards such as the ISO/IEC 14443 specific for identification cards, proximity cards and contactless integrated circuit cards. The coverage of various ISO standards ensures for NFC technology the global interoperability that makes the technology usable in different areas.
Maltego Part I - Intro and Personal Recon By Chris Gates, CISSP, GCIH, C|EH, CPTS According to their web site, “Paterva invents and sells unique data manipulation software. Paterva is headed by Roelof Temmingh who is leading a light and lethal team of talented software developers.” WebGoat - Learn the hack - Stop the attack Learn the hack - Stop the attack WebGoat is a deliberately insecure application that allows interested developers just like you to test vulnerabilities commonly found in Java-based applications that use common and popular open source components. Description Web application security is difficult to learn and practice. Not many people have full blown web applications like online book stores or online banks that can be used to scan for vulnerabilities.
