http://malwareup.org NOTE: As of August 6th 2014, the information about Cryptolocker in this video is obsolete. Security researchers managed to procure ALL private keys and decryption is now possible for everyone. Simply follow the link, submit an encrypted file and your private key will be emailed to you: https://www.decryptcryptolocker.com/ After two months of struggling, I finally give CryptoLocker a somewhat in depth review. More information about the ransomware can be found here: http://www.bleepingcomputer.com/virus-removal/cryptolocker-ransomware-information Note: Removal for this malware is trivial, since once your files are encrypted, no antivirus can restore them. One can use Malwarebytes' to remove the program, but the files will still be damaged.

(CryptoWall removal guide) What is CryptoWall? How to decrypt encrypted files? CryptoWall is a new variant of the ransomware CryptoLocker virus. Crypto Wall is for the most part the same as CryptoDefense, CryptorBit and Cryptolocker other than the name change and different filenames for the ransom instructions. When Crypto Wall is installed it will scan your computer for data files and encrypt them. When CryptoWall is installed it will scan your computer for data files and encrypt them. It will then create files containing ransom instructions in every folder that it had encrypted a file. These ransom notes are DECRYPT_INSTRUCTION.HTML, DECRYPT_INSTRUCTION.TXT, and the DECRYPT_INSTRUCTION URL shortcut to the decryption service. DECRYPT_INSTRUCTION: What happened to your files ? All of your files were protected by a strong encryption with RSA-2048 using CryptoWall. More information about the encryption keys using RSA-2048 can be found here: http://en.wikipedia.org/wiki/RSA_(cryptosystem) What does this mean ? This means that the structure and data within your files have been irrevocably changed, you will not be able to work with them, read them or see them, it is the same thing as losing them forever, but with our help, you can restore them. How did this happen ? Especially for you, on our server was generated the secret key pair RSA-2048 - public and private. All your files were encrypted with the public key, which has been transferred to your computer via the Internet. Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server. What do I do ? Alas, if you do not take the necessary measures for the specified time then the conditions for obtaining the private key will be changed. If you really value your data, then we suggest you do not waste valuable time searching for other solutions because they do not exist. ... Message presented in the CryptoWall ransom payment page: You did not pay in time for decryption, that's why the decryption price increases 2 times. At the moment, the cost of decrypting your files is 1000 USD/EUR. In case of failure to 04/06/14 - 11:36 your key will be deleted permanently and it will be impossible to decrypt your files. ...

If you are seeing “Your personal files are encrypted by CTB-Locker” message pop up, then you are infected with CTB-Locker virus! The message states that if you want your files decrypted, you have to pay ransom within 96 hours. In the past few weeks, a new version CTB-Locker, aka Critroni, campaign has been underway that uses emails that pretend to be fax notifications.

CBT Locker usually istall on your system with the help of a Trojan. Once infected with CTB-Locker it will scan your computer for data files and encrypt them so they are no longer accessible. In the past any file that was encrypted would have its file extension changed to .CYPCWVI,CTB,CTB2 or others.

This is a step-by-step instruction (tutorial) about how to get rid of / remove the annoying Cryptolocker malware from your computer completely without the need of a safemode boot, if you find this tutorial useful, please SUBSCRIBE :) Some details about Cryptolocker: CryptoLocker is a ransomware trojan which targets computers running Microsoft Windows[1] and first surfaced in September 2013. A CryptoLocker attack may come from various sources; one such is disguised as a legitimate email attachment. When activated, the malware encrypts certain types of files stored on local and mounted network drives using RSA public-key cryptography, with the private key stored only on the malware's control servers. The malware then displays a message which offers to decrypt the data if a payment (through either Bitcoin or a pre-paid voucher) is made by a stated deadline, and threatens to delete the private key if the deadline passes.

My PGP/GPG key is RSA 2048-bit, but I put the private key on Gnuk Token
 
45:05
NIIBE Yutaka https://summit.debconf.org/debconf14/meeting/144/my-pgpgpg-key-is-rsa-2048-bit-but-i-put-the-private-key-on-gnuk-token/ In this casual session, I will demonstrate Gnuk Token, which is built by Free Software and free hardware design. I will demonstrate NeuG standalone device, which can generate random numbers at 70KiB/s, too. My PGP/GPG key is RSA 2048-bit now. I understand that some person doesn't want to sign my key, because it looks weaker. I develop Gnuk, the firmware for USB Token, which is compatible to OpenPGP card, under GPLv3. My original purpose/goal was not to put a person into a dilemma: computing freedom vs. better security. I think that I have achieved the goal somehow, and it's strong enough (RSA 2048-bit) and it's not that slow (1.4sec to sign), IMO. It is unfortunate for me that Debian community demands RSA 4096-bit or more. Thus, another dilemma is still there; longer key length or better control of private key by Free Software. Good news is that I have implemented Ed25519 (for signing) already, and going to implement Curve25519 (for decryption) in Gnuk. Besides, I am also GnuPG developer, and try to implement Curve25519 support now. It will be good if GnuPG 2.1 will be released and people will enjoy Gnuk Token with Ed25519/Curve25519 until Debconf15 in Germany. During the development of Gnuk, I develop NeuG, the true random number generator to generate private keys on the device. The entropy source is built-in A/D converter. I realized that this feature is very useful, and I build standalone device (just for generating random numbers). FST-01 is a reference board for Gnuk/NeuG. It has STM32F103 as MCU which runs at 72MHz. It has no crypto accelerator. Schematic design and PCB design are available as free hardware design. Material is available at gobby.debian.org: debconf14 → bof → gnuk

The Cryptolocker malware has been getting a tremendous amount of attention recently. Cryptolocker is part of a class of malware known as ransomware. The idea behind ransomware is to encrypt the victim's files and only provide decryption capabilities if the victim pays the attacker. Ransomware is an age-old concept in malware, first appearing in the AIDS malware trojan seen in 1989. This video, by Sourcefire Chief Scientist Zulfikar Ramzan, describes the mechanics of cryptolocker and explains how it uses public-key cryptography to hold a victim's data at ransom. The private decryption key is only released to the user if they pay the equivalent of $300 USD via Bitcoin or MoneyPak. Read the full article: http://sfi.re/1iSkRM9

[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.

CryptoLocker
 
08:43
CryptoLocker was a ransomware trojan which targeted computers running Microsoft Windows and was first observed by Dell SecureWorks in September 2013. CryptoLocker propagated via infected email attachments, and via an existing botnet; when activated, the malware encrypts certain types of files stored on local and mounted network drives using RSA public-key cryptography, with the private key stored only on the malware's control servers. The malware then displays a message which offers to decrypt the data if a payment (through either Bitcoin or a pre-paid cash voucher) is made by a stated deadline, and threatened to delete the private key if the deadline passes. If the deadline is not met, the malware offered to decrypt data via an online service provided by the malware's operators, for a significantly higher price in Bitcoin. Although CryptoLocker itself is readily removed, files remained encrypted in a way which researchers considered infeasible to break. Many said that the ransom should not be paid, but did not offer any way to recover files; others said that paying the ransom was the only way to recover files that had not been backed up. Some victims claimed that paying the ransom did not always always lead to the files being decrypted. This video is targeted to blind users.

Adam Young, Malicious Cryptography - Exposing Cryptovirology (February 27, 2004)
 
55:51
From the CISR video library (http://www.cisr.us) Dr. Adam Young, Cigital Malicious Cryptography - Exposing Cryptovirology February 27, 2004 at the Naval Postgraduate School (http://www.nps.edu) ABSTRACT Cryptography is commonly regarded as an enabling technology. It allows for confidential information transmission over untrusted networks as well as the ability to prove the origin of messages. It is a technology that is critical in an on-line world. However, cryptography is also a very powerful disabling technology. In recent years there has been a significant amount of research into using well-known cryptographic paradigms and tools for the purposes of undermining the security of computer systems once internal access is acquired. This talk will give an overview of a new book that details this dark side of cryptography. The book is entitled "Malicious Cryptography: Exposing Cryptovirology," and is authored by Adam Young and Moti Yung (published by John Wiley & Sons). Some of the more noteworthy attacks that are described in the book are the following. It is shown how to use public key cryptography to mount reversible denial-of-service attacks. A virus attack is detailed in which the virus asymmetrically encrypts host data (that has not been backed-up). The effects of the attack can only be reversed if the attacker agrees to use his or her own private decryption key. It is shown how to devise a cryptovirus that steals data from a host machine without revealing that which is sought, even if the virus is under constant surveillance. It is shown how to design a password snatching cryptotrojan that makes it virtually impossible to identify the author when the encrypted passwords are retrieved. Furthermore, it is intractable to determine if the cryptotrojan is encrypting anything at all when all even when all of its actions are recorded and analyzed. Finally, cryptotrojans are described that attack industry-standard cryptosystems. By design, these Trojans give the attacker covert access to the private keys of users and are extremely robust against reverse-engineering. When implemented in tamper-resistant devices the theft cannot be detected by anyone save the attacker. The book also covers various countermeasures that can help protect against these attacks. About Dr. Adam Young Dr. Adam Young is a Research Scientist at Cigital. He is responsible for researching and developing software and techniques to help support the research goals for Cigital's research contracts. In his first year at Cigital, Adam has served as a primary investigator on a research project for the DoD. Adam Young recently worked for Lockheed Martin Global Telecommunications. Prior to this he was a Member of Technical Staff (MTS) at Lucent Technologies in the Secure Systems Research Division. Before joining Lucent he worked as a cryptography consultant for CertoCo (a spin-off of Banker's Trust). Dr. Young holds a BS in Electrical Engineering from Yale University, an MS in Computer Science from Columbia University, and a PhD in Computer Science from Columbia University that was awarded with Distinction. He gives invited talks regularly and will be giving an upcoming talk at the Palo Alto Research Center (PARC) on his forthcoming book [[i]]. He will also be giving an invited talk at the Sixth International Joint Meeting of the AMS and the Sociedad Matematica Mexicana (SMM), Special Session on Coding Theory and Cryptography, in Houston. The session is being held by Neal Koblitz. Dr. Young has also given invited talks at NYU, Bell Labs, and Sandia National Labs. He has taught computer science courses at Columbia University and is a member of the International Association for Cryptologic Research (IACR). He has published numerous papers on cryptography, computer security, and algorithmic number theory and his next paper will be presented in the Cryptographer's Track of the RSA Conference, 2004 [[ii]].

Very Secure but Affordable Ultimately, if you do a lot of simple file encryption, Secret will make your life easier and more importantly more secure and private. That said, Secret is compact, functional and, especially if the recipient of the encrypted message/files also has the app installed, it's an all-round good and affordable option. Benefits of using Secret : Add extra protection to Passwords or Crypto Private Keys Safely exchange information by email - without revealing your password or sensitive information. Once the document is saved, nobody can decrypt it without the correct Secret Key set by the user. State of the art encryption behind a simple interface. Powerful AES 256 Encryption Secret may be as easy to use as your favorite word processor, but behind the scenes it uses powerful AES 256 encryption to ensure your private information cannot be read by others. Secret isn't fancy, but it does get a basic job done, and well.

CryptoWall Decrypter What happened to your files ? All of your files were protected by a strong encryption with RSA-2048 using CryptoWall. More information about the encryption keys using RSA-2048 can be found here: http://en.wikipedia.org/wiki/RSA_(cryptosystem) What does this mean ? This means that the structure and data within your files have been irrevocably changed, you will not be able to work with them, read them or see them, it is the same thing as losing them forever, but with our help, you can restore them. How did this happen ? Especially for you, on our server was generated the secret key pair RSA-2048 - public and private. All your files were encrypted with the public key, which has been transferred to your computer via the Internet. Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server. What do I do ? Alas, if you do not take the necessary measures for the specified time then the conditions for obtaining the private key will be changed. If you really value your data, then we suggest you do not waste valuable time searching for other solutions because they do not exist. If you have important files and want them back you have to decrypt with this tool. I can provide you this program together with the secret key. All i need is the character ids that found on your infected files.. This tool if for the old version of cryptowall i can also generate keys for new version (cryptowall 3.0) with brute force.. pm me with your fb email address if interested.

CryptoLocker
 
08:46
CryptoLocker is a ransomware trojan which targets computers running Microsoft Windows and first surfaced in September 2013. A CryptoLocker attack may come from various sources; one such is disguised as a legitimate email attachment. When activated, the malware encrypts certain types of files stored on local and mounted network drives using RSA public-key cryptography, with the private key stored only on the malware's control servers. The malware then displays a message which offers to decrypt the data if a payment is made by a stated deadline, and threatens to delete the private key if the deadline passes. If the deadline is not met, the malware offers to decrypt data via an online service provided by the malware's operators, for a significantly higher price in Bitcoin.

Encryption and Decryption || Ransomware Virus || Whatsapp End to End Encryption
 
02:35
Encryption is widely used on the internet to protect user information being sent between a browser and a server, including passwords, payment information and other personal information that should be considered private. Organizations and individuals also commonly use encryption to protect sensitive data stored on computers, servers and mobile devices like phones or tablets. How encryption works Unencrypted data, often referred to as plaintext, is encrypted using an encryption algorithm and an encryption key. This process generates ciphertext that can only be viewed in its original form if decrypted with the correct key. Decryption is simply the inverse of encryption, following the same steps but reversing the order in which the keys are applied. Today's most widely used encryption algorithms fall into two categories: symmetric and asymmetric. Encryption method How the encryption operation works Symmetric-key ciphers, also referred to as "secret key," use a single key, sometimes referred to as a shared secret because the system doing the encryption must share it with any entity it intends to be able to decrypt the encrypted data. The most widely used symmetric-key cipher is the Advanced Encryption Standard (AES), which was designed to protect government classified information. Symmetric-key encryption is usually much faster than asymmetric encryption, but the sender must exchange the key used to encrypt the data with the recipient before the recipient can perform decryption on the ciphertext. The need to securely distribute and manage large numbers of keys means most cryptographic processes use a symmetric algorithm to efficiently encrypt data, but use an asymmetric algorithm to securely exchange the secret key. Asymmetric cryptography, also known as public key cryptography, uses two different but mathematically linked keys, one public and one private. The public key can be shared with everyone, whereas the private key must be kept secret. The RSA encryption algorithm is the most widely used public key algorithm, partly because both the public and the private keys can encrypt a message; the opposite key from the one used to encrypt a message is used to decrypt it. This attribute provides a method of assuring not only confidentiality, but also the integrity, authenticity and nonreputability of electronic communications and data at rest through the use of digital signatures. Benefits of encryption The primary purpose of encryption is to protect the confidentiality of digital data stored on computer systems or transmitted via the internet or any other computer network. A number of organizations and standards bodies either recommend or require sensitive data to be encrypted in order to prevent unauthorized third parties or threat actors from accessing the data. For example, the Payment Card Industry Data Security Standard requires merchants to encrypt customers' payment card data when it is both stored at rest and transmitted across public networks. ---------------------------------------------------------- Follow Us On Facebook:https://www.facebook.com/Tech-Shaders-1594928477233615/ ---------------------------------------------------------- Follow Us On Instagram:https://tanmay_pandey786 ---------------------------------------------------------- Hey Friends You are Watching Tech Shaders Youtube Channel.

RANSOMWARE Explained | How to be Safe? IN HINDI/URDU/BHOJPURI
 
03:08
Ransomware is a subset of malware in which the data on a victim's computer is locked, typically by encryption, and payment is demanded before the ransomed data is decrypted and access returned to the victim. The motive for ransomware attacks is nearly always monetary, and unlike other types of attacks, the victim is usually notified that an exploit has occurred and is given instructions for how to recover from the attack. Payment is often demanded in a virtual currency, such as bitcoin, so that the cybercriminal's identity isn't known. Ransomware malware can be spread through malicious email attachments, infected software apps, infected external storage devices and compromised websites. A growing number of attacks have used remote desktop protocol and other approaches that don't rely on any form of user interaction. In a lockscreen variant of a ransomware attack, the malware may change the victim's login credentials for a computing device; in a data kidnapping attack, the malware may encrypt files on the infected device, as well as other connected network devices. While early instances of these attacks sometimes merely "locked" access to the web browser or to the Windows desktop -- and did so in ways that often could be fairly easily reverse-engineered and reopened -- hackers have since created versions of ransomware that use strong, public-key encryption to deny access to files on the computer. Famous ransomware: CryptoLocker and WannaCry Perhaps the first example of a widely spread attack that used public-key encryption was Cryptolocker, a Trojan horse that was active on the internet from September 2013 through May of the following year. The malware demanded payment in either bitcoin or a prepaid voucher, and experts generally believed that the RSA cryptography used -- when properly implemented -- was essentially impenetrable. In May 2014, however, a security firm gained access to a command-and-control server used by the attack and recovered the encryption keys used in the attacks. An online tool that allowed free key recovery was used to effectively defang the attack. In May 2017, an attack called WannaCry was able to infect and encrypt more than a quarter million systems globally. The malware uses asymmetric encryption so that the victim cannot reasonably be expected to recover the (private and undistributed) key needed to decrypt the ransomed files. ==================================== Free Study Materials For All GOVT.
