DEF CON 21 - Michael Perklin - ACL Steganography Permissions to Hide Your Porn
 
44:49
ACL Steganography - Permissions to Hide Your Porn MICHAEL PERKLIN SECURITY RESEARCHER Everyone's heard the claim: Security through obscurity is no security at all. Challenging this claim is the entire field of steganography itself - the art of hiding things in plain sight. Most people know you can hide a text file inside a photograph, or embed a photograph inside an MP3. But how does this work under the hood? What's new in the stego field? This talk will explore how various techniques employed by older steganographic tools work and will discuss a new technique developed by the speaker which embodies both data hiding and data enciphering properties by encoding data inside NTFS volumes. A new tool will be released during this talk that will allow attendees to both encode and decode data with this new scheme. Michael Perklin (@mperklin) is currently employed as a Senior Investigator within the Corporate Investigations department of an Enterprise class telecommunications firm. Throughout his career he has performed digital-forensic examinations on over a thousand devices and has processed petabytes of information for electronic discovery. Michael has spoken at security conferences internationally about a variety of topics including digital forensics, computer security, data hiding, and anti-forensics. Michael holds numerous security-related degrees, diplomas and certifications, is a member of the High Technology Crime Investigations Association, and is an avid information security nut who loves learning about new ways to break things.

FREE File Encryption and Decryption Software in JAVA
 
12:20
You can download the source code and the executable from here: https://github.com/arlenebatada/File-Encryption-and-Decryption-Application-in-JAVA Do you wish to convert your music to a form in which others cannot listen it? Do you wish to convert your movies to a form in which others cannot watch them? Do you wish to convert your documents to a form in which others cannot read them? Do you wish to convert your executable files to a form in which others cannot execute them? If your answer to any of the above questions is "YES" then this software is definitely for you. With this software you can perform ENCRYPTION and encrypt your video files, audio files, text files, executable files, pdf, or any other file of your choice. This way, without your password, files such as movies, music, pdf, documents, images, etc. won't open. Executable files will no longer be in a state to be executed. Would you like to have your encrypted files back in the form they used to be? Don't worry. It is also other way around. With the password you had used for encryption you can perform DECRYPTION and convert your files back to their original form. Moreover, the application does NOT store your passwords. Instead it uses SHA-512 hashing algorithm to verify the password.

Hiding The Text And Image Message Of Variable Size Using Encryption And Com
 
06:06
ABSTRACT Steganography is a science and art of communicating in writing such a way that the presence of message is detected. Steganography is focuses on hiding of a secret message into ordinary messages and the extraction of this message into itsdestination using provided techniques in such a way onlysender and receiver are able to disclose it. Steganography technique can be applied on text, image, video or audio files.Steganography is written in character including hash marking,but its usage within imainto ordinary image file in such a way that an attacker cannotdetect the presence of contents in the hidden messages.Today, there are many different techniques of embedding thatenable us to hiding message in a given object. The secretmessage can be hidden in an image file using Steganographybecause in this technique all requirements must be satisfied.plain text, cipher text) is based on replacing bits of sourcebased images but Jpeg images are mostly used inSteganography algorithm because it is most popular lossimage compression methods. The Steganography uses of leastused for purpose of secret for encryption and decryption. Infile for authentication of login and logout the system formaking more secure systems. The only authorized users canhide and disclose the message. The text files of different sizeare used to test the system and found that the system satisfiesall requirements of Steganography and the system is more secured.

Steganography Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. OR Steganography is data hidden within data. Steganography is an encryption technique that can be used along with cryptography as an extra-secure method in which to protect data. Steganography techniques can be applied to images, a video file or an audio file. Step 1: Get a picture Step 2: Generate the text message you want to conceal Step 3: Open MS Publisher 2010 Step 4: Type the text you want to conceal into MS Publisher text box Step 5: Copy and paste the picture on the text you want to conceal Step 6: Convert the MS Publisher file into PDF Step 7: Open the newly convered PDF file to verify the text has been concealed Step 8: Use a PDF to MS Word converter to convert the PDF to .doc file format Step 9: Open the newly converted .doc file in MS Word Step 10: Delete the picture in MS Word to reveal the concealed text To do it my way, here is what I used Picture, Text, MS Publisher 2010, MS Word 2010, PDF Reader(Foxit), PDF2Wordv2.0 Record PC Screen - Filmora Music - Simple Deciduous

A Project on Data Security using Audio steganography in C#/VS10
 
03:29
Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. Steganography works by replacing bits of useless or unused data in regular computer files (such as graphics, sound, text, HTML, or even floppy disks ) with bits of different, invisible information. This hidden information can be plain text, cipher text, or even images. In a computer-based audio Steganography system, secret messages are embedded in digital sound. The secret message is embedded by slightly altering the binary sequence of a sound file. Existing audio Steganography software can embed messages in WAV, AU, and even MP3 sound files. Embedding secret messages in digital sound is usually a more difficult process than embedding messages in other media, such as digital images. These methods range from rather simple algorithms that insert information in the form of signal noise to more powerful methods that exploit sophisticated signal processing techniques to hide information. Thereby I have chosen C# based windows application to serve the purpose. C# is world’s most widely used window user based application platform. I have decided to make application to serve the application of Audio Steganography. To contact me, Name: Rajan Yadav Email Id: [email protected]

This video shows you how to hide a document within an image using a Stenography tool called Xiao. Use your favorite image editor (Gimp, Photoshop, Paint, etc..) and save the image with a .bmp extension. With your favorite text editor (Word, Notepad, etc..) create your document and save it with a .txt extension. Nobody will ever know it is there. You can extract the document when you need to work on it, then re-save it within the image. You can also do this within audio files or video files. I hope this video helped you. Thanks for watching, Have a great day !!

The gzip data format uses the same algorithm as the DeflateStream class, but can be extended to use other compression formats. The format can be readily implemented in a manner not covered by patents. This class cannot be used to compress files larger than 4 GB. Compressed GZipStream objects written to a file with an extension of .gz can be decompressed using many common compression tools; however, this class does not inherently provide functionality for adding files to or extracting files from .zip archives. The compression functionality in DeflateStream and GZipStream is exposed as a stream. Data is read in on a byte-by-byte basis, so it is not possible to perform multiple passes to determine the best method for compressing entire files or large blocks of data. The DeflateStream and GZipStream classes are best used on uncompressed sources of data. If the source data is already compressed, using these classes may actually increase the size of the stream.

DEF CON 23 - Eijah - Crypto for Hackers
 
55:52
Hacking is hard. It takes passion, dedication, and an unwavering attention to detail. Hacking requires a breadth of knowledge spread across many domains. We need to have experience with different platforms, operating systems, software packages, tools, programming languages, and technology trends. Being overly deficient in any one of these areas can add hours to our hack, or even worse, bring us total failure. And while all of these things are important for a well-rounded hacker, one of the key areas that is often overlooked is cryptography. In an era dominated by security breaches, an understanding of encryption and hashing algorithms provides a tremendous advantage. We can better hone our attack vectors, especially when looking for security holes. A few years ago I released the first Blu-Ray device key, AA856A1BA814AB99FFDEBA6AEFBE1C04, by exploiting a vulnerability in an implementation of the AACS protocol. As hacks go, it was a simple one. But it was the knowledge of crypto that made it all possible. This presentation is an overview of the most common crypto routines helpful to hackers. We'll review the strengths and weaknesses of each algorithm, which ones to embrace, and which ones to avoid. You'll get C++ code examples, high-level wrapper classes, and an open-source library that implements all the algorithms. We'll even talk about creative ways to merge algorithms to further increase entropy and key strength. If you've ever wanted to learn how crypto can give you an advantage as a hacker, then this talk is for you. With this information you'll be able to maximize your hacks and better protect your personal data.

DEF CON 22 - Eijah - Saving Cyberspace by Reinventing File Sharing
 
48:47
Slides Here: https://defcon.org/images/defcon-22/dc-22-presentations/Elijah/DEFCON-22-Eijah-Saving-Cyberspace-by-Reinventing-File-Sharing-Updated.pdf Saving Cyberspace by Reinventing File Sharing Eijah Internet access is a basic human right, due to its unparalleled capacity to deliver content and information. Recently, our right to share files online has been under assault by governments, corporations, and others who fear openness and personal privacy rights. People have been persecuted, fined, and even imprisoned for simply sharing data electronically. As private conversations transition from the home to the web, we're losing our fundamental rights to privacy and personal beliefs. While many of us believe that information should be and can be freely shared, we are not without blame. As experts in our fields we have at our disposal an arsenal of tools, experience, and technologies to open up the Internet for limitless file sharing without fear of retribution or loss of personal privacy and freedom. Saving cyberspace means that there are times when we need to break the mold of old and stale thinking – creating something new and beautiful that has the power to change the world. This presentation is a free data manifesto, a historical analysis, and a recipe for creating a new approach to file sharing that's free from snooping, intervention, and interruption from all outside entities. If you've ever been concerned about the risks and insecurity of file sharing, make sure to attend. Understanding our right to share is the first step to changing the world. Eijah is a Senior Programmer at a world-renowned game development studio. He has over 15 years of software development and IT Security experience.

AV Evasion using MSFVENOM Hyperion and PEScrambler
 
10:41
This tutorial video will teach you on how to create a MSFVENOM payload encrypt it with x86/shikata_ga_nai 3x or 7x as you wish and do another 5x AES encryption with Hyperion and obfuscate its win32 binaries with PEScrambler. With this procedure we will try as much how to evade Anti-Viruses. In my case we have tried it with MS security essentials and windows defender that is built in with windows 8. **But please let me know if what anti virus you have that detected the payload with this technique.... This techniques are also used with Veil-Evasion but veil has far more complicated techniques that almost all AVs cannot detect. Hyperion can be downloaded: https://github.com/Veil-Framework/Veil-Evasion/tree/master/tools/hyperion --Already compiled to executable files.... PEScrambler can be downloaded: https://code.google.com/p/pescrambler/ -PEScrambler is a tool to obfuscate win32 binaries automatically. It can relocate portions of code and protect them with anti-disassembly code. It also defeats static program flow analysis by re-routing all function calls through a central dispatcher function.

Slides Here: https://www.defcon.org/images/defcon-22/dc-22-presentations/Denaro-Beardsley/DEFCON-22-Jim-Denaro-Tod-Beardsley-How-to-Disclose-and-Exploit-UPDATED.pdf How to Disclose an Exploit Without Getting in Trouble Jim Denaro CIPHERLAW Tod Beardsley ENGINEERING MANAGER, METASPLOIT PROJECT You have identified a vulnerability and may have developed an exploit. What should you do with it? You might consider going to the vendor, blogging about it, or selling it. There are risks in each of these options. This session will cover the risks to security researchers involved in publishing or selling information that details the operation of hacks, exploits, vulnerabilities and other techniques. This session will provide practical advice on how to reduce the risk of legal action and suggest several approaches to responsible disclosure. Jim Denaro (@CipherLaw) is the founder of CipherLaw, a Washington, D.C.-based consultancy and focuses his practice on the legal, technical, and ethical issues faced by innovators in information security. Jim is a frequent speaker and writer on legal issues in information security and has experience in a wide range of technologies, including intrusion detection and prevention, botnet investigation, malware discovery and remediation, and cryptography. Jim is a regular consultant on responsible disclosure policies and is involved in programs to shield researchers who disclose responsibly. Jim has completed professional coursework at MIT and Stanford in computer security and cryptography. He also holds technical certifications from the Cloud Security Alliance (CCSK) and Cisco Systems (CCENT), and has passed the CISSP examination (pending certification). Before becoming an attorney, Jim spent obscene amounts of time looking at PPC assembly in MacsBug. Tod Beardsley (@todb) is engineering manager for the open source Metasploit project, as well as one of the core developers on the framework. His background is primarily in intrusion prevention, vulnerability assessment and identification, anti-fraud/anti-phishing countermeasures, penetration testing and compliance auditing, intrusion detection and response, protocol analysis, and host hardening. He is also interested in computer crime forensics and recovery, reverse engineering and binary analysis, steganographic communication channels, and cryptography in general. Tod’s technical specialties include protocol analysis and reverse engineering, intrusion detection and prevention, phishing and online fraud, open source software engineering collaboration, and application vulnerability research and exploitation.
