How To Use PGP Encryption - PGP for Beginners www.VictorDozal.com What is PGP? In 3 minutes https://www.youtube.com/watch?v=1-MPcUHhXoc Generating your PGP keys https://www.igolder.com/pgp/generate-key/ Encrypting a message https://www.igolder.com/PGP/encryption/ Decrypting a message https://www.igolder.com/PGP/decryption/ In this tutorial, I will teach you how to use PGP encryption, including how to get your own PGP keys, encrypt messages, and decrypt messages. If you don't know what PGP encryption is, go ahead and watch my other video "What is PGP encryption? In 3 minutes" https://www.youtube.com/watch?v=1-MPcUHhXoc The three steps needed to use PGP keys are: 1. Generate your PGP keys somehow. 2. Encrypt a message using a PGP public key. 3. Decrypt a message using a PGP private key. If this tutorial helped you in any way, please don’t forget to like the video and subscribe to my channel, as you will be helping me to create more useful tutorials.

Check out our second video: https://youtu.be/9PVaDpMsyQE FAQ Q: What is so special about Game of Drones methods compared to other methods? A: Other methods can detect a nearby drone. But, they all fail to detect whether a specific POI is being streamed by a drone or not, a distinction that depends on the camera angle instead of the drone's location. Q: Can I apply Game of Drones methods? A: Yes you can. All you need is a laptop (with Linux OS) and a controlled flickering LED strip. Q: How is the streamed POI revealed? A: Modern video encoders use compression (delta framing) algorithms in order to provide high quality streams. There is a strong connection between the percentage of changing pixels in a frame and the bitrate that is required to encode the stream. Forcing a change to the pixels in a streamed video requires a higher bitrate to encode stream. Q: Does detecting a streamed POI from an encrypted FPV channel require crypto-analysis/hacking skills? A: No. Anyone with a limited set of computer skills can detect what is being streamed from an encrypted FPV channel by applying our methods. Q: Can these methods be applied to other FPV channels besides Wi-Fi FPV? A: Yes. We demonstrated our methods on Wi-Fi FPV, because it is so popular. You can detect a streamed POI from an encrypted FPV channel of any drone that uses delta framing algorithms for video encoding. However, you need to find the demodulation protocol (from layer 1 to layer 2) that converts the intercepted radio signals to binary. Q: What is the impact of this research? A: This is a game changer in the battle on privacy. It empowers the victim. Q: What areas will be influenced by this research? A: Some armies use drones for their daily tasks. For example, one of the units of the Israel Defense Forces uses the DJI Mavic. In addition, supplying a watermarked radio signal that was intercepted from a drone might even be considered as a proof in a court of law that a drone was used for spying on a specific target.

Automating packer and compiler/toolchain detection can be tricky and best and downright frustrating at worst. The majority of existing solutions are old, closed source or aren’t cross platform. Originally, a method of packer identification that leveraged some text analysis algorithms was presented. The goal is to create a method to identify compilers and packers based on the structural changes they leave behind in PE files. This iteration builds upon previous work of using assembly mnemonics for packer detection and grouping. New features and analysis are covered for identification and clustering of PE files. Speaker Bio: Mike Sconzo has been around the Security Industry for quite some time, and is interested in creating and implementing new methods of detecting unknown and suspicious network activity as well as different approaches for file/malware analysis. This includes looking for protocol anomalies, patterns of network traffic, and various forms of static and dynamic file analysis. He works on reversing malware, tool creation for analysis, and threat intelligence. Currently a lot of his time is spent doing data exploration and tinkering with statistical analysis and machine learning.

DIGITEC 2016: Digital Future Session on 'Encryption: blessing or curse for IT security' Encryption plays a crucial role in securing information systems and the business data they contain. External communications are routinely encrypted and network traffic inside an organisation is increasingly encrypted to reduce the risk that attackers that can get access to an organisation's vital information. Increasingly it is standard practice that information is encrypted for storage. But encryption can also be exploited by attackers. Malware can be hidden inside incoming encrypted communications so as to avoid antivirus scanning and to cover the exfiltration of sensitive information from data loss prevention systems. IT security defenders are looking for ways to look inside such traffic to protect the organisation. What are the legally sound, organisationally proportionate and technically effective measures that can be used to protect business systems against the misuse of encryption? This session will examine: • The risks associated with the use of encryption in an organisation • Technical options for defence against misuse of encryption • The organisational policy and legal issues associated Speakers • Keith Martin, Professor of Information Security, University of London • Maresa Meissl, Head of Unit of Information Security, Security Directorate, DG Informatics (EC) • Bart Preneel, Professor at Katholieke Universiteit Leuven • Vincent Steckler, Chief Executive Offive, Avast Software Moderator: Ken Ducatel, Director, IT Security Directorate, DG Informatics (EC)

Generally, the hidden messages appear to be (or be part of) something else: images, articles, shopping lists, or some other cover text. For example, the hidden message may be in invisible ink between the visible lines of a private letter. Some implementations of steganography that lack a shared secret are forms of security through obscurity, whereas key-dependent stenographic schemes adhere it. The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny. Plainly visible encrypted messages—no matter how unbreakable—arouse interest, and may in themselves be incriminating in countries where encryption is illegal.[2] Thus, whereas cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent, as well as concealing the contents of the message. Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include stenographic coding inside of a transport layer, such as a document file, image file, program or protocol. Media files are ideal for stenographic transmission because of their large size. For example, a sender might start with an innocuous image file and adjust the color of every 100th pixel to correspond to a letter in the alphabet, a change so subtle that someone not specifically looking for it is unlikely to notice it. Moreover, it is feasible to utilize the relation between two or more different network protocols to enable secret communication. These applications fall under the term inter-protocol steganography.[21] Alternatively, multiple network protocols can be used simultaneously to transfer hidden information and so-called control protocols can be embedded into stenographic communications to extend their capabilities, e.g. to allow dynamic overlay routing or the switching of utilized hiding methods and network protocols.

In this episode of Full Disclosure we will demonstrate how to crack MD5 password hashes. MD5 (Message-Digest algorithm 5) is a hash function commonly used by websites to encrypt passwords. MD5 is a one-way hash; therefore, to crack the password you most try every possible dictionary word and if that does not work, every possible letter/number/symbol combination.
