Data recovery is the process of salvaging and handling the data through the data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media such as internal or external hard disk drives, solid-state drives (SSD), USB flash drive, storage tapes, CDs, DVDs, RAID, and other electronics. Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system (OS).

This is the simplest hacking guide that works on any HTTP enabled authentication website. It even worked on Facebook (when HTTP was the authentication method). Who can do it? Anyone from any operating system, be that a Linux, Windows or Mac with Wireshark. The implications are massive, but do we even realize it in our everyday usage?

SlowHTTPTest is a highly configurable tool that simulates some Application Layer Denial of Service attacks. It works on majority of Linux platforms, OSX and Cygwin – a Unix-like environment and command-line interface for Microsoft Windows.

Oxford Dictionary got 171,476 words. I'm #cracking my #Wifi #WPA2 password at 159159186.00 PMK's per second. Need I say more? There are just too many guides on Cracking Wifi WPA/WPA2 passwords using different methods. Everyone has their own take on it. Personally, I think there’s no right or wrong way of cracking a Wireless Access Point. Following way is my way and I found it extremely efficient and fast during my tests for Cracking Wifi WPA/WPA2 passwords using pyrit cowpatty in Kali Linux where I attacked with Dictionary using either cuda or calpp (cal++) and at the same time I used WiFite to fast track a few things. This whole process was used in Kali Linux and it took me less than 10 minutes to crack a Wifi WPA/WPA2 password using pyrit cowpatty WiFite combination using my laptop running a AMD ATI 7500HD Graphics card.

To protect your website, you need to be able to block or absorb malicious traffic. Webmasters can talk to their hosting provider about DDoS attack protection. They can also route incoming traffic through a reputable third-party service that provides distributed caching to help filter out malicious traffic — reducing the strain on existing web servers. Most such services require a paid subscription, but often cost less than scaling up your own server capacity to deal with a DDoS attack.

Two-step verification (also known as Two-factor authentication, abbreviated to TFA) is a process involving two stages to verify the identity of an entity trying to access services in a computer or in a network. This is a special case of a multi-factor authentication which might involve only one of the three authentication factors (a knowledge factor, a possession factor, and an inheritance factor) for both steps. If each step involves a different authentication factor then the two-step verification is additionally two-factor authentication.
