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:
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:
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:
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:
- Audio Files.
- Virtual Drives.
After the encryption process, the malware threatens to delete files in 24 hours if a ransom of around $100 is not paid.
