This article aims to help you by showing how to remove the new NOOBCRYPT ransomware infection from your computer and how to restore .su encrypted files.
A new version of the well known NOOBCRYPT ransomware which was previously unlocked has reappeared. The ransomware virus, this time claims to use the RSA-2048 and AES-128 encryption algorithms in order to encrypt the files on the computers which have become it’s unfortunate victims. The virus also changes the wallpaper of the victimized computer to a ransom note wallpaper which threatens victims to pay in 24 hours or else their important documents, photos, audio and other files are likely to be deleted.
Threat Summary
Name
NOOBCRYPT
Type
Ransomware, Cryptovirus
Short Description
Encrypts the files on your computer and gives you 24 hours to pay $100 or else it claims to destroy your files.
Symptoms
Adds a lockscreen with a ransom note and the files may no longer be openable.
Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.
NOOBCRYPT Ransomware – How Does It Infect
The infection process of this ransomware virus is conducted in a very similar way to most ransomware viruses. The primary method which it uses is called malspam. It is essentially when the cyber-criminals mask a malicious executable or a web link as a legitimate one that poses as a document or another legitimate file. This process tricks the victim that the attachment is an invoice, a receipt or any other type of file that only seems legitimate. The messages are accompanied by big company names, to increase their legitimacy, like:
PayPal.
FedEx.
DHL.
UPS.
Most e-mail attachments may be executable files or JavaScript files, but the cases with Microsoft Word documents with malicious macros are increasing. This method of infection is particularly interesting because the legitimate document only becomes malicious when you click on the “Enable Content” button which enables macros, similar to what the graphic below displays:
Other methods of infection may also include the usage of fake setups of free programs you may search for download online. In addition to this, other types of patches, game cracks or others may be used as a pretext to infect a computer with NOOBCRYPT.
NOOBCRYPT Ransomware – More Information
The NOOBCRYPT ransomware is believed to be coded in .NET and it may have multiple different errors, just like the previous version.
Once infected your computer, NOOBCRYPT ransomware may begin to create the a completely random named sub-key in the Windows Registry Editor. The key it targets is the HKEY_CURRENT_USER key. In the random sub-key within it, there are values that are created with random names.
Another action this virus performs is to change the wallpaper of the infected computer with a threatening one that has the following message to victims:
NOOBCRYPT YOU HAVE BEEN CRYPTED! Your files has been crypted! All of your files are encrypted with RSA-2048 and AES- 128 ciphers- More information about the RSA and AES can be found here: Decrypting of your files is only possible with the private key and decrypt program which is on our secret server. Time left to pay (if you don’t pay, all your files will be PERMANENTLY deleted!) 23 Hours | 59 Minutes | 50 Seconds REFRESH TO SEE YOUR TIMER! In order to receive your files back, you have to pay a RANSOM and get a LICENSE which you will use in our DECRYPTOR to get your files back! Please Transfer 0.03615 BTC (100$) to: {cyber-criminals address} Waiting for payment, current status: Not Paid Your License will appear here once paid: (hidden)
This ransom note is reported not only to change the wallpaper, but the new wallpaper to be a direct lockscreen as well, denying any access to the computer.
The virus is not reported to tamper with any Run and RunOnce registry sub-keys or mess with the shadow volume copies of the infected computer, so it is possible that files could be recovered if you have enabled shadow volume copies and manage to bypass the lockscreen.
NOOBCRYPT Ransomware – Encryption Process
For the encryption process, this ransomware virus may use AES-128 bit encryption algorithm in order to render the files no longer openable. After the files are encrypted, the virus generates symmetric decryption key which may be further encrypted via the RSA-2048 encryption algorithm. After this process has finished, the virus may leave the files unopenable, possibly with the .su file extension.
NOOBCRYPT is very specific when it encrypts user files. It is very careful to skip important Windows files and aims to encrypt files which are often opened, such as:
Videos.
Documents.
Music.
Audio Files.
Archives.
Virtual Drives.
After the encryption process, the malware threatens to delete files in 24 hours if a ransom of around $100 is not paid.

4. Try to Restore files encrypted by NOOBCRYPT
Try to Restore Files Encrypted by NOOBCRYPT
Ransomware infections and NOOBCRYPT aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
