This blog article aims to help you by showing how you can remove Naampa.exe .crptd ransomware virus and try to get back .crptd files using other methods.

A virus, known by the names Unlckr or Naampa ransomware has been detected in the wild. Also known as the .crptd file virus, this threat is not one that you would want infecting your computer out of all that there are out there. The primary reason for that is that the virus alters the structure of your files using a cipher which makes them seem corrupt. This military-grade cipher is known as RSA-2048. The encryption of your important documents is done with the one and only purpose to follow the instructions in it’s ransom note !—-README—-!.jpg. They aim to get the victim to pay a hefty ransom fee in order to get his files decrypted.

What May Follow If .crptd File Virus Ransomware Finds a Way into Your System?

If this Trojan sneaks in, it will not reveal its presence immediately. It will first perform an encryption of all partitions of your hard disk. Depending on the amount of files you have there, the process may take between 15-20 mins and a few hours. .crptd File Virus uses a ‘strong’ encryption, which would be either RSA or AES. These ciphers are indeed difficult to break without the corresponding key. Unfortunately, this tool cannot be extracted from your system because it is simply not there. As soon as the encryption ends, .crptd File Virus automatically transfers the key towards distant hosts, which serve as Command and Control (C&C) servers. As of now, there is no data that some security researcher has managed to breach into these databases, but it may happen in the future. .crptd File Virus encourages the user to pay a ransom of 0.15 Bitcoins, which is currently equal to $108. The person has limited time to act – only 48 hours, which is a scare mechanism. The key is supposed to get destroyed when the timer reaches zero.

How Does the Infection with .crptd File Virus Begin?

The developers of this ransomware try to deploy it to the computers of the victims via a variety of clever tactics. The hackers most commonly rely on spam email campaigns to reach the unsuspecting PC users. With only a few clicks, the cyber criminals may send the payload of .crptd File Virus towards hundreds or even thousands of users at once. This process also involves very little operational costs and a high success rate, which explains why it is so preferred. While the spam emails is a single tactic, it can come in very different forms. The hackers may try to look as if the malicious message was coming from banks, financial platforms like PayPal, shipping companies like DHL or famous email providers. Usually, the content of the letters mentions some unauthorized transactions or other information that may worry the recipient.

The email itself contains very little information, and the supplementary data is supposed to appear in the attached file. If you make the mistake to download or open it, you may infect your machine with .crptd File Virus. The problem may also happen if you install programs like Adobe or Java from random suspicious platforms like the majority of porn sites.

What to and Not to Do After You Lose Your Files Due to .crptd File Virus Ransomware?

The first and most important thing to remember is not to succumb to the pressure. No matter how the hackers threaten you, you should not pay the ransom. It is true that the sum is not that high in comparison to other file-encoding Trojans, but even if the hackers receive your money, they may not release the precious key. Or if they do, you should expect them to continue creating and spreading more ransomware, which means you may get infected by a similar cyber threat anytime in the future. The right action is to delete .crptd File Virus immediately. Since this parasite compromises various areas of the system, it will be best to eliminate it via special security software. When the removal is completed, you can use some free decryptor that may manage to break the ciphers. Another possibility is to use a data restoring tool, which may revert your PC to an earlier date. If you have a recent copy of your hard drives, you can safely import all of your files back to your device.

Recover files encrypted by the .crptd File Virus Ransomware.

Method 1: Using Shadow Explorer. In case you have enabled File history on your Windows Machine one thing you can do is to use Shadow Explorer to get your files back. Unfortunately some ransomware viruses may delete those shadow volume copies with an administrative command to prevent you from doing just that.

Method 2: If you try to decrypt your files using third-party decryption tools. There are many antivirus providers who have decrypted multiple ransomware viruses the last couple of years and posted decryptors for them. Chances are if your ransomware virus uses the same encryption code used by a decryptable virus, you may get the files back. However, this is also not a guarantee, so you might want to try this method with copies of the original encrypted files, because if a third-party program tampers with their encrypted structure, they may be damaged permanently. Here are the vendors to look for:

• Kaspersky.
• Emsisoft.
• TrendMicro.

Method 3: Using Data Recovery tools. This method is suggested by multiple experts in the field. It can be used to scan your hard drive’s sectors and hence scramble the encrypted files anew as if they were deleted. Most ransomware viruses usually delete a file and create an encrypted copy to prevent such programs for restoring the files, but not all are this sophisticated. So you may have a chance of restoring some of your files with this method. Here are several data recovery programs which you can try and restore at least some of your files:
