  1. New Site Provides Free Decryption Keys to Those Still Impacted by the Ransomware Following Its Takedown MILPITAS, CA -- (Marketwired) -- 08/06/14 -- FireEye, Inc. (NASDAQ: FEYE), the leader in stopping today's advanced cyber attacks, and Fox-IT, Europe's leading cyber threat solution provider, today announced DecryptCryptoLocker, a new service assisting victims of the CryptoLocker ransomware. Available immediately for no cost at www.decryptcryptolocker.com, the service can offer help to the users of machines whose files remain encrypted by CryptoLocker. CryptoLocker is a type of ransomware that typically targeted small enterprises, encrypting the files of computers it infected and giving victims 72 hours to pay the ransom to receive a private key that decrypts their files. Although the Department of Justice has reported that CryptoLocker has been neutralized, many CryptoLocker victims have not been able to decrypt their files. DecryptCryptoLocker is designed to provide users with private keys to allow for the decryption of files that were encrypted by CryptoLocker. To use the DecryptCryptoLocker tool, users need to: 1. Identify a single, CryptoLocker-encrypted file that they believe does not contain sensitive information. 2. Upload the non-sensitive encrypted file to the DecryptCryptoLocker portal. 3. Receive a private key from the portal and a link to download and install a decryption tool that can be run locally on their computer. 4. Run the decryption tool locally on their computer, using the provided private key, to decrypt the encrypted files on their hard drive. DecryptCryptoLocker is available globally and does not require users to register or provide contact information. "We are excited to work with Fox-IT to offer a free resource that can help thousands of businesses affected by the spread of CryptoLocker over the last few months," said Darien Kindlund, director of threat intelligence, FireEye. "No matter the type of cyber breach that a business is impacted by, it is our goal to resolve them and get organizations back to normal operations as quickly as possible." "The criminals continue to push the boundaries; Fox-IT's InTELL team and FireEye have shared expertise and investment to deliver a free service that demonstrates there are plenty of good guys who are there to help those who are the victims of the criminals," said Andy Chandler, senior vice president, Fox-IT.

  2. How To Use 7-Zip To Encrypt Files If you need strong command line encryption on Linux, look no further than 7zip You have information on your machines that needs to be secure. This could be client data, company secrets, or your own personal information that you don't want viewed by the wrong person. To that end, you'll go to some rather challenging means to protect that information. But what if that task could be made considerably easier? Although some might not think of the command line as the easier option, there are some CLI tools that do make short shrift of a task. Such is the case with 7zip. Although this tool is typically used for zipping and unzipping files, it also includes the ability to encrypt and decrypt those files. I want to walk you through the installation and usage of 7zip for file encryption. I'll be demonstrating on Ubuntu Server, but the tool can be used on most Linux distributions. What you'll need A running Linux distribution A user with sudo privileges Some data to encrypt How to install the 7zip package on Linux distributions Chances are slim your Linux distribution includes the 7zip package. In order to install the package that includes the encryption features, log in to your Linux machine, open a terminal window, and issue the following command: sudo apt-get install p7zip-full -y To install on a different type of distribution, use a similar command as shown above, substituting apt-get for the likes of dnf or zypper. That's all there is to the installation. How to encrypt files with 7zip Let's say you have the file webservers, which contains important information about the web servers in your data center. To encrypt that file with 7zip, issue the command: 7z a -p -mx=9 -mhe -t7z webservers.7z webservers The options used above are: a: Add files to archive -p: Prompt for a password -mx=9: Level of compression (9 being ultra) -mhe: Encrypt file names -t7z: Generate a 7z archive You will be prompted to create a passphrase for the encryption. Once you've done that, the new encrypted file webservers.7z is created. You can also encrypt multiple files. Say you have the files webservers and kubernetes to be encrypted into the file data.7z. The command for this would be: 7z a -p -mx=9 -mhe -t7z data.7z webservers kubernetes the above command would create the encrypted data.7z file, encrypted by the password of your choice. Once you've encrypted the files, you should then delete the originals. Why? Because those original files (in our examples webservers and kubernetes) aren't encrypted. Only the newly created .7z files are encrypted. So delete those files with the command: rm webservers kubernetes How to decrypt files with 7zip Those files wouldn't be of any use to you if you couldn't decrypt them. So how do you do that? We have the files data.7z and webservers.7z. With 7z, file decryption is done like so: 7za e data.7z or 7za e webservers.7z In either instance, you'll be asked for the passphrase you created during the encryption process. If you failed to delete the original files (which you shouldn't neglect to do), 7z will ask if you want to overwrite the existing files--in our examples that would be webservers and kubernetes (Figure A). Figure A Once you've decrypted the file(s), you can then view their contents. And that's the gist of using 7zip to encrypt and decrypt files. For anyone who needs strong command line encryption on Linux, this might well be the ideal choice for you. Source
