Stampado ransomware removal instructions
What is Stampado?
A ransomware service called Stampado is new malware available on the dark market. This virus is advertised and sold on the 'dark web' - anyone can purchase a lifetime license and proliferate the virus without little effort. After infiltrating computers, Stampado encrypts various files and appends the name of each encrypted file with the .locked extension. Stampado then opens a ransom-demand window.
This opened window contains a message informing users of the encryption. It is stated that to decrypt files, victims must purchase a secret key. Stampado uses an asymmetric (AES-256) encryption algorithm, generating public (encryption) and private (decryption) keys during the locking process. Be aware that the decryption without the private key is impossible, and since it is stored on remote servers, cyber criminals attempt to sell this key to victims. The window contains two timers that signify time remaining until the next deletion of files, and the payment deadline. Stampado deletes random files every six hours - developers call this process "Russian Roulette". Furthermore, victims have only 96 hours to pay the ransom. After this period, the private key is supposedly deleted and decryption becomes impossible. The size of ransom is currently unknown. To receive payment instructions, victims must contact cyber criminals via an email address provided (this address often differs, and users who purchase a license must provide their email address). Victims are also allowed to attach one selected file, which will then be decrypted and returned - this supposedly guarantees that decryption is possible. Be aware, however, that many cyber criminals ignore victims, despite paymentments made. Therefore, never attempt to pay or contact these people - paying will not deliver any positive results and you will lose your money. Unfortunately, there currently are no tools capable of decrypting files compromised by Stampado. The only solution to this problem is to restore your system and/or files from a backup.

A variant of Stampado ransomware called Zelta, uses HiddenMan0135@protonmail.com email address for communication with victims and .locked extension for encrypted files:
This malware shares many similarities with CryptoWall, CryptoLocker, Locky, and many other ransomware-type viruses. Most use asymmetric algorithms to encrypt files. The only noticeable difference between them is the size of ransom. Furthermore, most ransomware is distributed using fake software update tools, malicious files attached to spam emails, peer-to-peer networks, and trojans. The key to computer safety is caution. Keep your installed applications up-to-date and have a legitimate anti-virus/anti-spyware suite installed on your computer. Furthermore, never open any files sent from unrecognized/suspicious email addresses and download your desired files/programs from trusted sources (such as official download websites).
Update 23 July, 2016 - Fabian Wosar from Emsisoft have released a decrypter for this ransomware. Using this tool victim’s of this ransomware can regain control of their compromised data for free. Download it HERE.
Update 1 February 2017 - Security researchers from Avast have released a decrypter for Stampado ransomware. You can download it HERE.

Log in to the account infected with the Stampado virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.
If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.
Video showing how to remove ransomware virus using "Safe Mode with Command Prompt" and "System Restore":
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 Stampado 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 Stampado ransomware files.
To restore individual files encrypted by this ransomware, try using 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 Stampado 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 encrypting ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and Malwarebytes Anti-Ransomware, which artificially implant group policy objects into the registry to block rogue programs such as Stampado ransomware.)
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.
