What is HELP_YOUR_FILES?

Recently, a new version of CryptoWall ransomware has been released. This is not the first update to this ransomware - cyber criminals have released a fourth version also known as HELP_YOUR_FILES ransomware. This new file-encrypting malware not only changes the extensions of files stored on the computer, but also changes the names to prevent victims recognizing them (example of an encrypted file name: '8354no9f.7gt8'). After HELP_YOUR_FILE has encrypted victim data, it demands payment of a $700 (1.79 Bitcoins) ransom. If the user does not pay within a given time frame, the ransom doubles to $1400 or 1400 (3.58 BTC). Information about the payment (time frame, consequences of not paying the ransom, attempts to decrypt using third party software, step-by-step payment instructions, etc.) is stored in HELP_YOUR_FILES.PNG, HELP_YOUR_FILES.TXT, and HELP_YOUR_FILES.HTML files, which are generated in each directory containing encrypted data.

HELP_YOUR_FILES uses the RC4 encryption method. As with the previous versions of CryptoWall, this ransomware infiltrates Explorer.exe, and then deletes all Shadow Volume Copies, disables System Restore, and turns off Windows Startup Repair using bcdedit. Although the ransomware is easy to remove, decrypting affected files without paying the ransom is impossible - the key required for decryption is stored on HELP_YOUR_FILES command-and-control servers, which are managed by cyber criminals. The only way to solve this problem is to restore your data from a backup.

HELP_YOUR_FILES decrypt instructions

The existence of computer viruses such as HELP_YOUR_FILES, CTB Locker, CryptoLocker, TeslaCrypt, and CryptorBit presents a strong case for maintaining regular backups of your files. Paying the ransom supports the malicious business of cyber criminals. Furthermore, there is no guarantee that the files will ever be decrypted. Be aware that HELP_YOUR_FILES is distributed using malicious email messages with bogus attachments - zipped files supposedly containing resumes, shipping information, etc, The attachments are JavaScript files that (when executed) download other infectious executable files, storing them in a Windows %Temp% folder and then running them. Most ransomware viruses are distributed using fake downloads (for example, torrents, fake software updates, etc.). For this reason, be cautious when downloading files from untrusted sources. Use a legitimate anti-virus or anti-spyware suite and keep all installed applications up-to-date.

HELP_YOUR_FILES ransomware additional information regarding data encryption:

Additional information about the files encrypted by HELP_YOUR_FILES ransomware

Text presented in HELP_YOUR_FILES.PNG, HELP_YOUR_FILES.TXT and HELP_YOUR_FILES.HTML files:

Cannot you find the files you need? Is the content of the files that you have watched not readable? It is normal because the files’ names, as well as the data in your files have been encrypted. Congratulations!!! You have become a part of large community of CryptoWall. If you are reading this text that means that the software CryptoWall has removed from your computer.
What is encryption? Encryption is a reversible transformation of information in order to connect it from unauthorised persons but providing at the same time access to it for authorised users. To become an authorised user and make the process truly reversible i.e to be able to decrypt your files you need to have a special private key. In addition to the private key you need the decryption software with which you can decrypt your files and return everything in its place. I almost understood but what do I have to do? The first thing you should do is to read the instructions to the end. Your files have been encrypted with the CryptoWall software; the instructions that you find in folders with encrypted files are not viruses, they are you helpers. After reading this text 100% of people turn to a search engine with the word CryptoWall where you’ll find a lot of thoughts, advice and instructions. Think logically - we are the ones who closed the lock on your files and we are the only ones who have this mysterious key to open them. Any of your attempts to restore you files with the third-party tools can be fatal for encrypted files. The fact that changing data within the encrypted files (as 100% of software to restore files do this, except the special decryption software) you break damage to the files and it will be impossible to decrypt the files. This is the same as to collect a mosaic when some mosaics items were lost, broken or not put in its place - the picture will not emerge, the software to restore the files will not be able to lay down the picture, and ruin it completely and irreversibly. Use the software to restore files can ruin your files forever, only through your fault. Remember that any intervention of the extraneous software to restore files encrypted with the CryptoWall software may be the point on no return. In case if these simple rules are violated we will not be able to help you, and we will not try because you have been warned. For your attention the software to decrypt the files (as well as the private key that come fitted with it) is a paid product. After purchasing the software package you can: 1.Decrypt all your files. 2. Work with your documents. 3. View your photos and other media content. 4. Continue your habitual and comfortable work at the computer. If you are aware whole importance and criticality of the situation, then we suggest you go directly to your personal page where you will be given final instructions, as well as guarantees to restore your files.
What do you have to do with these addresses? If you browse the instructions in TXT format (if you have instructions in HTML (the file that has an icon of your Internet browser) then for the sake of simplicity it is better to run it). Additional information: Instructions to restore your files are only in the folders where you have encrypted files. For your convenience the instructions are made in three files formats - html, txt and png. Unfortunately, antivirus companies cannot protect and moreover restore your files but they make things worse removing the instructions to restore encrypted files. The instructions are not malware, they have informative nature only, so any claims on the absence of any instructions files you can send to your antivirus company. CryptoWall Project is not malicious and is not intended to harm a person and his/her information data. This project is conducted for the sole purpose of instruction in the field of information security, as well as certification of antivirus products for their suitability for data protection. Together we make the Internet a better and safer place. If you oversee this text in the Internet and understand that something is wrong with your files and you have no instructions to restore files, contact your antivirus support. Remember that the worst has already happened and now the further life of your files depends directly in your determination and speed of your actions.

Isolating the infected device:

Some ransomware-type infections are designed to encrypt files within external storage devices, infect them, and even spread throughout the entire local network. For this reason, it is very important to isolate the infected device (computer) as soon as possible.

Step 1: Disconnect from the internet.

The easiest way to disconnect a computer from the internet is to unplug the Ethernet cable from the motherboard, however, some devices are connected via a wireless network and for some users (especially those who are not particularly tech-savvy), disconnecting cables may seem troublesome. Therefore, you can also disconnect the system manually via Control Panel:

Navigate to the "Control Panel", click the search bar in the upper-right corner of the screen, enter "Network and Sharing Center" and select search result: Disconnecting computer from the Internet (step 1)

Click the "Change adapter settings" option in the upper-left corner of the window: Disconnecting computer from the Internet (step 2)

Right-click on each connection point and select "Disable". Once disabled, the system will no longer be connected to the internet. To re-enable the connection points, simply right-click again and select "Enable". Disconnecting computer from the Internet (step 3)

Step 2: Unplug all storage devices.

As mentioned above, ransomware might encrypt data and infiltrate all storage devices that are connected to the computer. For this reason, all external storage devices (flash drives, portable hard drives, etc.) should be disconnected immediately, however, we strongly advise you to eject each device before disconnecting to prevent data corruption:

Navigate to "My Computer", right-click on each connected device and select "Eject": Ejecting external storage devices

Step 3: Log-out of cloud storage accounts.

Some ransomware-type might be able to hijack software that handles data stored within "the Cloud". Therefore, the data could be corrupted/encrypted. For this reason, you should log-out of all cloud storage accounts within browsers and other related software. You should also consider temporarily uninstalling the cloud-management software until the infection is completely removed.

Identify the ransomware infection:

To properly handle an infection, one must first identify it. Some ransomware infections use ransom-demand messages as an introduction (see the WALDO ransomware text file below).

Identify ransomware-type infection (step 1)

This, however, is rare. In most cases, ransomware infections deliver more direct messages simply stating that data is encrypted and that victims must pay some sort of ransom. Note that ransomware-type infections typically generate messages with different file names (for example, "_readme.txt", "READ-ME.txt", "DECRYPTION_INSTRUCTIONS.txt", "DECRYPT_FILES.html", etc.). Therefore, using the name of a ransom message may seem like a good way to identify the infection. The problem is that most of these names are generic and some infections use the same names, even though the delivered messages are different and the infections themselves are unrelated. Therefore, using the message filename alone can be ineffective and even lead to permanent data loss (for example, by attempting to decrypt data using tools designed for different ransomware infections, users are likely to end up permanently damaging files and decryption will no longer be possible even with the correct tool).

Another way to identify a ransomware infection is to check the file extension, which is appended to each encrypted file. Ransomware infections are often named by the extensions they append (see files encrypted by Qewe ransomware below).

Identify ransomware-type infection (step 2)

This method is only effective, however, when the appended extension is unique - many ransomware infections append a generic extension (for example, ".encrypted", ".enc", ".crypted", ".locked", etc.). In these cases, identifying ransomware by its appended extension becomes impossible.

One of the easiest and quickest ways to identify a ransomware infection is to use the ID Ransomware website. This service supports most existing ransomware infections. Victims simply upload a ransom message and/or one encrypted file (we advise you to upload both if possible).

Identify ransomware-type infection (step 3)

The ransomware will be identified within seconds and you will be provided with various details, such as the name of the malware family to which the infection belongs, whether it is decryptable, and so on.

Example 1 (Qewe [Stop/Djvu] ransomware):

Identify ransomware-type infection (step 4)

Example 2 (.iso [Phobos] ransomware):

Identify ransomware-type infection (step 5)

If your data happens to be encrypted by a ransomware that is not supported by ID Ransomware, you can always try searching the internet by using certain keywords (for example, ransom message title, file extension, provided contact emails, cryptowallet addresses, etc.).

Search for ransomware decryption tools:

Encryption algorithms used by most ransomware-type infections are extremely sophisticated and, if the encryption is performed properly, only the developer is capable of restoring data. This is because decryption requires a specific key, which is generated during the encryption. Restoring data without the key is impossible. In most cases, cyber criminals store keys on a remote server, rather than using the infected machine as a host. Dharma (CrySis), Phobos, and other families of high-end ransomware infections are virtually flawless, and thus restoring data encrypted without the developers' involvement is simply impossible. Despite this, there are dozens of ransomware-type infections that are poorly developed and contain a number of flaws (for example, the use of identical encryption/decryption keys for each victim, keys stored locally, etc.). Therefore, always check for available decryption tools for any ransomware that infiltrates your computer.

Finding the correct decryption tool on the internet can be very frustrating. For this reason, we recommend that you use the No More Ransom Project and this is where identifying the ransomware infection is useful. The No More Ransom Project website contains a "Decryption Tools" section with a search bar. Enter the name of the identified ransomware, and all available decryptors (if there are any) will be listed.

Restore files with data recovery tools:

Depending on the situation (quality of ransomware infection, type of encryption algorithm used, etc.), restoring data with certain third-party tools might be possible. Therefore, we advise you to use EaseUS Data Recovery Wizard Pro. This tool supports over a thousand data types (graphics, video, audio, documents, etc.) and it is very intuitive (little knowledge is necessary to recover data).

▼ Download
EaseUS Data Recovery Wizard Pro

By downloading any software listed on this website you agree to our Privacy Policy and Terms of Use. Trial version of EaseUS Data Recovery Wizard Pro is capable of scanning drives and listing recoverable files - to restore them, you must purchase a license.

Step 1: Perform a scan.

Hover your mouse over the partition you wish to scan and select "Scan". You can also select a specific folder, or click shortcut icons to scan the Desktop or Recycle Bin: Scanning the storage drive with EaseUS Data Recovery Wizard PRO (step 1)

Wait for EaseUS Data Recovery Wizard Pro to complete the scan. The scanning duration depends on the volume of files (both in quantity and size) that you are scanning (for example, several hundreds gigabytes could take over an hour to scan). Therefore, be patient during the scanning process. We also advise against modifying or deleting existing files, since this might interfere with the scan. If you add additional data (for example, downloading files/content) while scanning, this will prolong the process: Scanning the storage drive with EaseUS Data Recovery Wizard PRO (step 2)

Step 2: Recover data.

Once the process is complete, select the folders/files you wish to restore and simply click "Recover". Note that some free space on your storage drive is necessary to restore data. Note also that the trial version of EaseUS Data Recovery Wizard Pro is only capable of scanning drives and listing recoverable files - to restore them, you must purchase a license: Recovering data with EaseUS Data Recovery Wizard Pro

Step 3: Save the scan session (optional).

We recommend that you save the scanning session once you have completed recovery, in case you decide to recover additional files later. Simply click the "Save Scan Session" icon in the upper-right corner of the screen and choose the location for the file to be saved. This will save a lot of time, since you will not need to re-scan the storage drive the next time you wish to restore something. Bear in mind, however, that data removed after the scanning session has finished will not be listed: Saving scan session in EaseUS Data Recovery Wizard Pro

Create data backups:

Proper file management and creating backups is essential for data security. Therefore, always be very careful and think ahead.

Partition management: We recommend that you store your data in multiple partitions and avoid storing important files within the partition that contains the entire operating system. If you fall into a situation whereby you cannot boot the system and are forced to format the disk on which the operating system is installed (in most cases, this is where malware infections hide), you will lose all data stored within that drive. This is the advantage of having multiple partitions: if you have the entire storage device assigned to a single partition, you will be forced to delete everything, however, creating multiple partitions and allocating the data properly allows you to prevent such problems. You can easily format a single partition without affecting the others - therefore, one will be cleaned and the others will remain untouched, and your data will be saved. Managing partitions is quite simple and you can find all necessary information on Microsoft's documentation web page.

Data backups: The most reliable backup method is to use an external storage device and keep it unplugged. Copy your data to an external hard drive, flash (thumb) drive, SSD, HDD, or any other storage device, unplug it and store it in a dry place away from sun and extreme temperatures. This method is, however, quite inefficient, since data backups and updates need to be made regularly. You can also use a cloud service or remote server. Here, an internet connection is required and there is always the chance of a security breach. Therefore, you should consider using an application to create data backups locally.

EaseUS Todo Backup

By downloading any software listed on this website you agree to our Privacy Policy and Terms of Use. To use full-featured product, you have to purchase a license for EaseUS Todo Backup. 30 days free trial available.

We recommend using the EaseUS Todo Backup application. The "Home" edition of EaseUS Todo Backup is usually more than adequate for regular users, however, the "Business" edition is more suitable for companies and large computer networks. The EaseUS Todo Backup application provides extensive data protection features. You can easily create backups, and encrypt and compress them for enhanced protection and storage saving purposes. It also allows you to set backup schedules, create bootable devices, and restore the system if a crash occurs. You can easily choose where to store the created backup: locally; uploaded to an external drive; FTP; cloud storage, or elsewhere. In summary, EaseUS Todo Backup is an all-in-one tool, which provides all features required to properly backup your data.

Creating a data backup:

The backup process is virtually identical regardless of the item (file, partition, entire system) you wish to backup. Taking the File Backup feature as an example:

Step 1: Choose which item to backup.

Click on the "Menu" icon in the upper-left corner of the screen to reveal the menu and select "File Backup": Creating data backups with EaseUS Todo Backup tool (step 1)

Select the files you want to backup. You can also enter a name and description of the backup that will be created: Creating data backups with EaseUS Todo Backup tool (step 2)

Step 2: Change the default settings.

The EaseUS Todo Backup application provides a variety of additional options that can be added/modified while creating the backup. For example, you can encrypt data (add a password), select the compression rate (how much the backup should be compressed), performance (how many system resources should be allocated), add an email notification (you receive an email once the process is complete) and so on.

To open the options window, click the "Backup options" button in the lower-left corner of the screen: Creating data backups with EaseUS Todo Backup tool (step 3)

Select the settings you want to change and click "Save". You can also reset your changes by clicking "Reset to initial settings": Creating data backups with EaseUS Todo Backup tool (step 4)

Step 3: Select the backup destination.

As mentioned above, EaseUS Todo Backup allows you to choose where backups are saved - locally or externally.

Click the "Browse..." button and select the location you want the backup to be saved: Creating data backups with EaseUS Todo Backup tool (step 5)

Step 4: Safety measures and process completion.

Depending on the location you have chosen, there are a number of measures you should or should not take. If you are uploading to an internet-connected location (for example, Cloud storage, FTP, etc.), be sure to maintain your internet connection, otherwise you will have to start again. The same applies to external storage devices - do not unplug them until the process is complete.

The progress bar displays estimated time remaining until completion. Large backups (hundreds of gigabytes) can take hours to create (depending on storage device speed, internet connection, etc.). Therefore, the application also allows you to optionally choose what the system should do (shut down, sleep or hibernate) once the process has finished: Creating data backups with EaseUS Todo Backup tool (step 6)

The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups.
