Locky Imposter ransomware removal instructions
What is Locky Imposter?
First discovered by malware security researcher, dao ming si, Locky Imposter (also known as "PyLocky") is a ransom-type virus that imitates another high-risk ransomware infection called Locky. After stealthily infiltrating the system, Locky Imposter encrypts data using the RSA and AES encryption algorithms, creates a copy of each file, and then appends filenames with the ".locky" extension (e.g., "sample.jpg" is renamed to "sample.jpg.locky"). Updated variants of this ransomware use ".lockedfile" and ".lockymap" extensions for encrypted files. Ultimately, there are two copies of each existing file (one with the original name and extension, and another with the ".locky" extension), both are encrypted and unusable. Once data is encrypted, Locky Imposter generates a text file (named "LOCKY-README.TXT") and places a copy in every existing folder.
As usual, the new text file contains a message informing users of the encryption and encouraging them to visit Locky Imposter's website and purchase the decryption tool. Note, however, is that the message is in English, French, Italian, and Korean. Therefore, it is safe to assume that developers target mainly users from the associated countries. As mentioned above, Locky Imposter uses RSA and AES cryptographies. Therefore, each victim receives two unique keys that are necessary to restore data. All keys are stored on a remote server controlled by cyber criminals and users are encouraged to purchase decryption tools with keys embedded within. It is also stated that payment must be submitted within 96 hours, otherwise decryption keys are deleted. The cost is not specified, yet it typically fluctuates between $500 and $1500. In any case, no matter what the cost, do not pay. Cyber criminals are very likely to ignore victims, once payments are submitted. Therefore, paying typically gives no positive result and users are scammed. Therefore, you are strongly advised to ignore all requests to purchase decryption tools. There are currently no tools capable of cracking RSA and AES cryptographies and restoring data free of charge. Therefore, the only solution is to restore everything from a backup.

There are dozens of ransomware-type viruses such as Locky Imposter. The list of examples includes (but it is not limited to) CryptoConsole, TQV, Cryptes, Jigsaw, and Deep. Note that although these viruses are developed by different cyber criminals, their behavior barely differs - all encrypt data and make ransom demands. There are typically just two major differences: 1) cost of decryption, and; 2) type of encryption algorithm used. It is unfortunate that most ransomware uses algorithms that generate unique decryption keys. Therefore, unless the virus is not fully developed or has certain bugs/flaws (e.g., the key is hard-coded, stored locally or similar), restoring data without involvement of developers (contacting these people is not recommended) is impossible. Ransomware presents a strong case for maintaining regular data backups, however, it is important to store them on a remote server (e.g., Cloud) or unplugged storage device. If not, backups are encrypted with regular data.
How did ransomware infect my computer?

|Threat Type||Ransomware, Crypto Virus, Files locker|
|Symptoms||Can't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.|
|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate Locky Imposter virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Lack of knowledge and careless behavior are the main reasons for computer infections. Caution is the key to computer safety. Therefore, pay close attention when browsing the Internet and downloading/installing/updating software. Think twice before opening email attachments. Files that seem irrelevant or have been received from suspicious email addresses should never be opened. Furthermore, download your programs from official sources only (via direct download links) rather than using third party downloaders/installers. These tools often include rogue apps, and thus using them is not recommended. In addition, keep installed applications up-to-date. To achieve this, however, use implemented functions or tools provided by the official developer only. Having a reputable anti-virus/anti-spyware suite installed and running is also paramount. If your computer is already infected with Locky Imposter, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Update January 11, 2019 - Cisco Talos cyber-security company has recently released a tool that is capable of decrypting data compromised by Locky Imposter ransomware. However, this tool requires a PCAP of the outbound connection attempt to the C&C servers. This connection occurs immediately after encryption and contains a variety of system data, including Initializing Vector (IV) and password (key, generated at runtime) which is used to encrypt data. Without this PCAP and said values decryption is impossible. You can download the tool and find more information/instructions in this GitHub page.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Locky Imposter ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Locky Imposter ransomware files.
To restore individual files encrypted by this ransomware, try using the Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Locky Imposter are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Locky Imposter ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
