[WanaKiwi] WannaCry Ransomware Decryption Tool [Unlock Files Without Paying Ransom]
 
03:50
WannaCry Ransomware Decryption Tool Released Free; Unlock Files Without Paying Ransom If your PC has been infected by WannaCry – the ransomware that wreaked havoc across the world last Friday – you might be lucky to get your locked files back without paying the ransom of $300 to the cyber criminals. ► [PES 2018] Full CPY REPACK Download & Install [Tutorial] https://youtu.be/8x_TcjTs3gY ► PTE Patch 7.0 Download + Install [Tutorial] https://youtu.be/Ixe4wWDK2i4 ► PES 2017 Download & Install [Tutorial] https://youtu.be/XXIo-K-NvXk Adrien Guinet, a French security researcher from Quarkslab, has discovered a way to retrieve the secret encryption keys used by the WannaCry ransomware for free, which works on Windows XP, Windows 7, Windows Vista, Windows Server 2003 and 2008 operating systems. WannaCry Ransomware Decryption Keys The WannaCry's encryption scheme works by generating a pair of keys on the victim's computer that rely on prime numbers, a "public" key and a "private" key for encrypting and decrypting the system’s files respectively. To prevent the victim from accessing the private key and decrypting locked files himself, WannaCry erases the key from the system, leaving no choice for the victims to retrieve the decryption key except paying the ransom to the attacker. But here's the kicker: WannaCry "does not erase the prime numbers from memory before freeing the associated memory," says Guinet. Based on this finding, Guinet released a WannaCry ransomware decryption tool, named WannaKey, that basically tries to retrieve the two prime numbers, used in the formula to generate encryption keys from memory, and works on Windows XP only. Note: Below I have also mentioned another tool, dubbed WanaKiwi, that works for Windows XP to Windows 7. "It does so by searching for them in the wcry.exe process. This is the process that generates the RSA private key. The main issue is that the CryptDestroyKey and CryptReleaseContext does not erase the prime numbers from memory before freeing the associated memory." says Guinet So, that means, this method will work only if: The affected computer has not been rebooted after being infected. The associated memory has not been allocated and erased by some other process. "In order to work, your computer must not have been rebooted after being infected. Please also note that you need some luck for this to work, and so it might not work in every case!," Guinet says. "This is not really a mistake from the ransomware authors, as they properly use the Windows Crypto API." While WannaKey only pulls prime numbers from the memory of the affected computer, the tool can only be used by those who can use those prime numbers to generate the decryption key manually to decrypt their WannaCry-infected PC’s files. WanaKiwi: WannaCry Ransomware Decryption Tool ► download link: http://j.gs/16891485/wkd OR http://j.gs/16891485/wktool Good news is that another security researcher, Benjamin Delpy, developed an easy-to-use tool called "WanaKiwi," based on Guinet's finding, which simplifies the whole process of the WannaCry-infected file decryption. All victims have to do is download WanaKiwi tool from Github and run it on their affected Windows computer using the command line (cmd). WanaKiwi works on Windows XP, Windows 7, Windows Vista, Windows Server 2003 and 2008, confirmed Matt Suiche from security firm Comae Technologies, who has also provided some demonstrations showing how to use WanaKiwi to decrypt your files. Although the tool won't work for every user due to its dependencies, still it gives some hope to WannaCry's victims of getting their locked files back for free even from Windows XP, the aging, largely unsupported version of Microsoft's operating system.

How to Create A Web App With External API Access using Wix Code
 
26:25
In this tutorial we'll take a first look at Wix Code and go through a practical real-world sample application. We will build a web application which lets you retrieve up to date information for any crypto currency. In the background a 3rd party REST API will be used to retrieve the needed information. By using Wix Code we will be initiating the web service call and we will be making sure the the result is displayed to the user on the website. Wix is a cloud-based website builder that traditionally has targeted people who want to create their web presence without coding. Now Wix has added a big new feature to their platform: Wix Code. With Wix Code you are now able to enhance your Wix website with database collections, dynamic content and custom forms. You can use JavaScript to include your own code in the website and you can take full control of the way the website is working. In these tutorials we will have a look at what you can actually do with Wix Code. You can just follow along by creating your free Wix.com (https://wix.com) account and follow the step-by-step instructions included. This post is sponsored by Wix.com.

How to create, list, or destroy virtual smart cards on Windows
 
05:45
Recommended: turn on CC (closed captioning) in this video! If your computer has a Trusted Platform Module (TPM) chip, and if it is enabled in the BIOS, then you can leverage some of the benefits of smart card security by creating a PIN-protected virtual smart card, which lives on the TPM in a protected memory space, similar to an expensive Hardware Security Module (HSM). You can use your enabled TPM to securely store a virtual smart card which can safely contain sensitive information, such as private keys from an RSA key pair. This video explains how to create, list, or destroy a virtual smart card (VSC) on Windows 10. IMPORTANT: Administrator privileges are required. Note #1: The "Admin Key" must be a 48-character hex-encoded value. Do NOT copy the admin key in this video; there's nothing magic or special about it. Just do a Google search for "convert plain text to hex". Type in any 24-character string of your choice in plain text, convert those 24-characters from plain text into hex, and then remove any spaces in the converted text. You should now have 48 characters of hexidecimal text, which you can use for the admin key. Note #2: The PIN Unlock Key (PUK) is useful whenever the virtual smart card is locked due to a user inputting an incorrect PIN too many times. If there is a lock, it is temporary, but you can input the PUK at that time to release the lock. Note #3: One practical application of this technology is to enable SSH to connect to a server. The public key would need to be already on the server in the "authorized_keys" file. The private key, in this case, would be safely protected in the TPM and unavailable for reading or copying or brute-forcing. The way you can access the private key in order to SSH to the server is to use software that leverages the Windows crypto API. Instead of using a program like PuTTY (which requires the path to a private key on the hard drive), use a patched version of PuTTY known as PuTTYWinCrypt (which can use Windows crypto APIs to access the private key on a specified virtual smart card). Below is the text that is used in the video. Replace the placeholder X's with your own values: ================================ NAME OF VIRTUAL SMART CARD: XXXXXXXXXXXXXXXX PIN: XXXXXXXXXXXXXXXX ADMIN KEY (must be a 48-character hex-encoded value): XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX PUK: XXXXXXXXXXXXXXXX COMMAND TO CREATE A VSC (using name of the virtual smart card above): tpmvscmgr.exe create /name "XXXXXXXXXXXXXXXX" /pin PROMPT /pinpolicy minlen 10 uppercase REQUIRED lowercase REQUIRED digits REQUIRED specialchars REQUIRED /AdminKey PROMPT /puk PROMPT /attestation AIK_AND_CERT /generate LIST ALL VSC's: wmic path win32_PnPEntity where "DeviceID like '%smartcardreader%'" get DeviceID,Name,Status COMMAND TO DESTROY A VSC (using a specific DeviceID): Tpmvscmgr destroy /instance "XXXXXXXXXXXXXXXXXXXXXXXXX" ================================

Microsoft Windows SDK
 
07:21
Microsoft Windows SDK, Platform SDK, and .NET Framework SDK are software development kits from Microsoft that contain header files, libraries, samples, documentation and tools required to develop applications for Microsoft Windows and .NET Framework. The difference between these three SDKs lies in their area of specialization: Platform SDK specializes in developing applications for Windows 2000, XP and Windows Server 2003. .NET Framework SDK is dedicated to developing applications for .NET Framework 1.1 and .NET Framework 2.0. Windows SDK is the successor of the two and supports developing applications for Windows XP, Windows Vista, Windows 7, Windows Server 2008, .NET Framework 3.0, .NET Framework 3.5, and .NET Framework 4.0. It contains extensive documentation and around 800 samples. This video is targeted to blind users. Attribution: Article text available under CC-BY-SA Creative Commons image source in video

Edge Conf 2: Offline
 
01:00:04
Web applications that work offline are still clearly in demand, but the standards lack support for even fairly basic use cases, and encourage developers to break fundamental navigation models of the web. There are two competing (or perhaps complementary), proposals to improve the situation, but it'll be a long slog. In the meantime, workarounds remain some of the most hackish in the web world. Are there any workable solutions to 'adding' offline to an existing site? What patterns allow offline to be used today while remaining open to replacement solutions in the future?

BLACKSHADES :Things you don't know about this deadly Ransomware
 
02:55
Is video mei maine Blackshades naam ke Ransomware ke bare mei bataya hai.As a CEH (certified ethical hacker) I know what all things a hacker can do!!! Blackshades is the name of a malicious trojan horse used by hackers to control computers remotely. The malware targets computers using Microsoft Windows -based operating systems.Over 500,000 computer systems have been infected worldwide with the software. In 2014, the United States Federal Bureau of Investigation (FBI) arrested one hundred people who had Blackshades in their computer. Blackshades infects computer systems by downloading onto a victim's computer when the victim accesses a malicious webpage (sometimes downloading onto the victim's computer without the victim's knowledge, known as a drive-by download) or through external storage devices, such as USB flash drives. Blackshades also included tools that assisted hackers in maximizing the amount of computer systems infected, such as a tool that sends infected links that masquerade as an innocuous site to other potential victims via the victim's social networking service. Blackshades can reportedly be used remotely to access an infected computer without authorization. Blackshades allows hackers to perform many actions on an infected computer remotely without authorization, including the ability to Access and modify files on the victim's computer. Log keystrokes on the victim's computer. Access to the webcam of the victim. Include the victim's computer in a botnet, which allows the attacker to perform denial-of-service attacks with the victim's computer, and usually along with other infected computers. Download and execute files on the victim's computer. Use the victim's computer as a proxy server. Blackshades reportedly can be used by computer hackers with little experience or by script kiddies, hackers that use programs developed by others to attack computer systems. Blackshades can also act as ransomware. Hackers using Blackshades can restrict access to the victim's computer and demand a ransom paid to the hacker in order for the restriction to be lifted.
