Aircrack-ng
I guess you all heard about that nasty vulnerability in OpenSSL. If not, you can read more about it on Wikipedia. Aircrack-ng, the software itself, is not affected at all since it doesn't rely on heartbeat, so recompiling is not necessary. Some parts of the website may have been affected (only if you had an account on it): Wiki Trac SVN If you are concerned, you can contact me about it.

Shamir's Secret Sharing Shamir's Secret Sharing is an algorithm in cryptography created by Adi Shamir. It is a form of secret sharing, where a secret is divided into parts, giving each participant its own unique part, where some of the parts or all of them are needed in order to reconstruct the secret. Counting on all participants to combine together the secret might be impractical, and therefore sometimes the threshold scheme is used where any of the parts are sufficient to reconstruct the original secret. Mathematical definition[edit]

 Log Files and Linux. Log Files and Linux. by Isaac Ok. Adrian asked me to write up a quick synopsis of the "lecture" I gave at the first meeting. This is pretty basic stuff. So if you already know how Linux log files work, don't expect to learn anything new or enlightening here. Anonymouse.org AnonWWW Many mice surf the web under the illusion that their actions are private and anonymous. Unfortunately, this is not the way it is. Every time you visit a site for a piece of cheese, you leave a calling card that reveals where you are coming from, what kind of computer you use, and other details. And many cats keep logs of all your visits, so that they can catch you!

How to hide files in JPEG pictures If you’re looking to hide files on your PC hard drive, you may have read about ways to encrypt folders or change the attributes on a file so that they cannot be accessed by prying eyes. However, a lot of times hiding files or folders in that way requires that you install some sort of software on your computer, which could then be spotted by someone else. I’ve actually written quite a few articles on how you can hide files and folders in Windows XP and Vista before, but here I’m going to show you a new way to hide files that is very counter-intuitive and therefore pretty safe! Using a simple trick in Windows, you can actually hide a file inside of the JPG picture file! You can actually hide any type of file inside of an image file, including txt, exe, mp3, avi, or whatever else.

Why does the government disallow dynamic languages? This Q&A is part of a weekly series of posts highlighting common questions encountered by technophiles and answered by users at Stack Exchange, a free, community-powered network of 100+ Q&A sites. Patrick asks: I know some people who are currently working on a project for the US military (low security level, non-combat, human resources type data). An initial state of the project code was submitted to the military for review, and they ran the program through some sort of security analyzer tool. It returned a report of known security issues in the code and required changes that needed to be implemented before delivery of the final product.

Cain & Abel Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, recovering wireless network keys, revealing password boxes, uncovering cached passwords and analyzing routing protocols. The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort. It covers some security aspects/weakness present in protocol's standards, authentication methods and caching mechanisms; its main purpose is the simplified recovery of passwords and credentials from various sources, however it also ships some "non standard" utilities for Microsoft Windows users. The latest version is faster and contains a lot of new features like APR (Arp Poison Routing) which enables sniffing on switched LANs and Man-in-the-Middle attacks.

By default, grep prints the matching lines. In addition, two variant programs egrep and fgrep are available.

The hacks work against Philips Smart televisions that have a feature known as Miracast enabled, Luigi Auriemma, a researcher with Malta-based ReVuln (Twitter handle @revuln), told Ars. Miracast allows TVs to act as Wi-Fi access points that nearby computers and smartphones can connect to so their screen output can be displayed on the larger set. The hacking vulnerability is the result of a recent firmware update that allows anyone within range to connect to the TV, as long as they know the hard-coded authentication password "Miracast." Once someone has connected to the Miracast-enabled Wi-Fi network, they can use publicly available software to download any personal files that may be contained on USB drives plugged in to the Philips Smart TV.

Transport Layer Security protocol Updated: June 12, 2014 This topic for the IT professional describes how the Transport Layer Security (TLS) protocol works and provides links to the IETF RFCs for TLS 1.0, TLS 1.1, and TLS 1.2. The TLS (and SSL) protocols are located between the application protocol layer and the TCP/IP layer, where they can secure and send application data to the transport layer. Because the protocols work between the application layer and the transport layer, TLS and SSL can support multiple application layer protocols. TLS and SSL assume that a connection-oriented transport, typically TCP, is in use. The protocol allows client and server applications to detect the following security risks:
