CTB Locker - 'Your personal files are encrypted' virus removal instructions

What is 'Your personal files are encrypted by CTB-Locker'?

CTB-Locker ransomware virus infiltrates operating systems via infected email messages and fake downloads (for example, rogue video players or fake Flash updates). After successful infiltration, this malicious program encrypts various files (*.doc, *.docx, *.xls, *.ppt, *.psd, *.pdf, *.eps, *.ai, *.cdr, *.jpg, etc.) stored on computers and demands a ransom payment of $300 (in Bitcoins) to decrypt them (encrypted documents receive the .ctbl files extension). Cyber criminals responsible for releasing this rogue program ensure that it executes on all Windows operating system versions (Windows XP, Windows Vista, Windows 7, and Windows 8). CTB-Locker ransomware creates AllFilesAreLocked.bmp DecryptAllFiles.txt and [seven random letters].html files within each folder containing the encrypted files.

These files contain instructions detailing how users may decrypt their files, and on use of the Tor browser (an anonymous web browser). Cyber criminals use Tor to hide their identities. 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. At time of research, there were no tools or solutions capable of decrypting files encrypted by Critroni. Note that the private key required to decrypt the files is stored on the CTB-Locker command-and-control servers, which are managed by cyber criminals. Therefore, the best solution is to remove this ransomware virus and then restore your data from a backup.

Ransomware infections such as CTB-Locker (including CryptoWall, CryptoDefense, CryptorBit, and Cryptolocker) present a strong case to maintain regular backups of your stored data. 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. To avoid computer infection with ransomware 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" or "FedEx Delivery Failure Notification"). Research shows that cyber criminals also use P2P networks and fake downloads containing bundled ransomware infections to proliferate Critroni. Currently, the 'Your personal files are encrypted' ransomware threat is delivered in the English and Russian languages. Therefore, countries speaking these languages are at the top of the target list of cyber criminals proliferating this malware.

Cyber criminals responsible for creating CTB-Locker ransomware use an affiliate scheme to spread their malware. Affiliates who register and distribute CTB-Locker receive 70% of the profits generated by this ransomware.

Note: at time of writing, there were no known tools capable of decrypting files encrypted by CTB-Locker without paying the ransom. By following this removal guide, you will be able to remove this ransomware from your computer, however, the affected files will remain encrypted. We will update this article as soon as there is more information available regarding decryption of compromised files.

Update February 13, 2016 - CTB-Locker or Cyber criminals using the name of this Windows ransomware have started encrypting websites hosted on Linux servers. The criminals demand a 0.4 BTC ransom to return data to the webmasters of the compromised websites. Previously known ransomware targeting webmasters in this manner was named Linux.Encoder.

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.

Jim Todd, could you give more specifics about the steps followed, what exactly was googled, and so on. Having this very issue today and would love to try to fix it ASAP while waiting for the computer guy to get here. Thanks!

Paradox FX

Can you call me? I want to understand better what you are saying.
Unfortunately I was unable to make a hard copy of my files before they
were encrypted. I have no originals. The files in question were on a
memory card. Are you saying there is something on the computer that the
attack happened on that can undo this???. I have my ransom note code key and
all that for all the good it has done me. Please if there is any
additional info you can provide I am eternally desperate for this
material. over 300 images for a job I never got to deliver. It is
killing
me. I do not have un encrypted versions of the files in question. They
were on a sd card that was en cryptecd before I could get it out. I
never made a hard copy

If I had un encrypted files why would I need to do this dual upload for decryption????

Thanks for the info, my website was hit by this ransomware - just restored everything from my hosting backup. No need for paying anyone.

Cihan Erdem

is there anyone who did decryption for infected CTB-Locker ?

TraineeAngel77

I have also been affected by this virus. The servers arew found in what few people know as the "Dark Web" which is run exclusively by the secret sect called the Illuminati (satan for Christians) and should be avoided at all costs. I DID have a backup and I managed to recover all my files. My heart goes out to you Scott as I know how I would feel had that happend to me.

I know it is easy to say AFTER the fact but backup is an absolute requirement. I got the virus after receiving a zip file containing the word 'Love' I suspected it to be a virus but was curious. I do use Acronis Recovery so if it did turn out to be something bad I can recover my PC. After clicking on the contents of the Zip file it contained a java script. This then proceeded to encrypt the described files in this report. I have since got rid of the encypted files and everything is ok now. Be careful with the Dark Web, thankfully it is difficult to surf with a normal browser but stay away from it. Check out Youtube for a hacker who tried to hack into it and what happend to him and what he found. Lets just say that it proves that conspiracy theories are actually FACT.

Tomas Meskauskas

Hi Scot, unfortunately at this time there are no tools known to decrypt the files encrypted by this ransomware. There's no use in contacting live support services or taking your computer or SD card with encrypted files to some computer repair shops etc. If the files are not crucial to you could put away your SD card and wait until some tool is developed to decrypt the compromised data. This could happen if authorities captures the cyber criminals are will be able to get access to their servers where the keys needed to decrypt the files are stored. Some people choose to pay the ransom and they regain their files this way, but by doing so you have to remember that you support such rogue business model and you encourage cyber criminals to continue creating such malicious software.

Paradox FX

I am told by one company that they can decrypt my files for 2,600 usd. Now I need 300 images restored that are encrypted on a memory card with CTB-LOCKER. You mention COMPUTING SPEED & POWER. Is that a factor in cost?? Is it actually possible to restore these files without getting the key from the hackers??? Is it better just to pay the bad guys??? it is certainly CHEAPER!!!!

Paradox FX

I am a professional photographer. A few weeks ago my computer was attacked by CTB-LOCKER the one with the black screen and code KEY. Proven Data Recovery has been able to identify the VARIENT of the virus I have. It is - RSA-2048 CTB-Locker encryption virus.
They want 2,600 for the decryption of 300 image files that this virus has encrypted on a SD CARD. The computer still reads close to 900mb of data on the card and I have been told by multiple sources that there is a chance my images are still there, but I have had no luck and it's going to take me quite some time to come up with this money so in mean time I am exploring other options and learning more about computers and code than I would otherwise have never cared to.
It angers me to no end that people can actually even do this. That they can hurt total strangers in this away. Hurt their jobs. Effect their lives just for the sake of doing so and then dangle our data in front of us so we freak out and jump. I refuse to pay this RANSOM and it is frustrating to no end that the supposed GOOD GUYS want WAY THE HELL MORE!! It's very backwards to me and does not seem right. It is almost impossible to get a simple strait answer from people in this area and there is a lot of double talk and I have bad a couple people remote access my computer and I see them try things even I have tried.
The files that are blocked were never on my hard drive. I didn't even have time to make a hard copy. One moment they were find and the next they were encrypted. I have done 2 system restored and a factory restore and computer has updated protection but the files remain locked on my card.
Is there any effective decryption for CTB-LOCKER - RSA-2048 CTB-Locker encryption virus
What are the odds? Is it even worth saving all this money for these people? He did ID the variant. Even that came as a shock. It's all I have to go on. Maybe, if you think you have a solution for me of course I would be willing to work put pay arrangement but I would need to see at lest SOME proof. Maybe do one or two that I can see. There are 300 on the card and I am really quite desperate for this material, or to be told convincingly and enough times that all hop is lost. I am not at that point yet.
Thanks for your time
Sincerely
Scott https://uploads.disquscdn.com/...

If you don't have a RP, you'll have to brute-force the decryption and that will need hardware of many thousands of $ in value, so unless you have a few thousand terraflops of processing power at your disposal, you can't do much.

I have the CBT-Locker virus - I was not aware - while gone I left a backup running to a removable hard drive. Was gone for more than 96 hours, Malware found and quarantined the virus too late - all files on hard disk and backup disk are CBT-Locker encrypted. How do I proceed, even if I have to pay?
