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.Įspecially for you, on our server was generated the secret key pair RSA-2048 - public and private. More information about the encryption keys using RSA-2048 can be found here: (cryptosystem) Message presented in HELP_RECOVER_INSTRUCTIONS.PNG, HELP_RECOVER_INSTRUCTIONS.HTML and HELP_RECOVER_INSTRUCTIONS.TXT files: What happened to your files ?Īll of your files were protected by a strong encryption with RSA-2048 using CryptoWall 3.0. Research shows that cyber criminals also use P2P networks and fake downloads, which contain bundled ransomware infections to proliferate CryptoWall.

To avoid computer infection with ransomware infections such as this, express caution when opening email messages since cyber criminals use various catchy titles to trick PC users into opening infected email attachments (for example, "UPS Exception Notification"). Note that paying the ransom as demanded by this ransomware is equivalent to sending your money to cyber criminals - you will support their malicious business model and there is no guarantee that your files will ever be decrypted. Ransomware infections such as CryptoWall (including CryptoDefense, CryptorBit, and Cryptolocker) present a strong argument to maintain regular backups of your stored data.

At time of research, there were no tools or solutions capable of decrypting files encrypted by CryptoWall.
PC users should beware that while the infection itself is not complicated to remove, decryption of files (encrypted using RSA 2048 encryption) affected by this malicious program is impossible without paying the ransom. Cyber criminals use Tor to hide their identities. These files contain instructions detailing how users may decrypt their files, and on use of the Tor browser (an anonymous web browser). CryptoWall ransomware creates HELP_RECOVER_INSTRUCTIONS.PNG, HELP_RECOVER_INSTRUCTIONS.HTML and HELP_RECOVER_INSTRUCTIONS.TXT files within each folder containing the encrypted files.

After successful infiltration, this malicious program encrypts files stored on users' computers (*.doc, *.docx, *.xls, *.ppt, *.psd, *.pdf, *.eps, *.ai, *.cdr, *.jpg, etc.) and demands payment of a $500 ransom (in Bitcoins) to decrypt them.Ĭyber criminals responsible for releasing this rogue program, ensure that it executes on all Windows versions (Windows XP, Windows Vista, Windows 7, and Windows 8). The CryptoWall ransomware virus infiltrates users' operating systems via infected email messages and fake downloads (for example, rogue video players or fake Flash updates).
