What is ShkolotaCrypt ransomware? And how does it execute its attack?

ShkolotaCrypt ransomware is a new file-encrypting malware found to be targeting Russian-speaking users. It applies a combination of AES and RSA encryption algorithms in encrypting the files in a computer. It demands a ransom of thousands of rubles in Dash crypto-currency which is equivalent to 0.1 Dash. It uses a “.crypted” extension in marking its encrypted files, the same with other ransomware threats like GlobeImposter and CryptoLocker.

Once it is able to infect a system, a malicious payload is dropped into the system responsible for loading ShkolotaCrypt on the infected machine. ShkolotaCrypt ransomware has the same functionalities as GlobeImposter and will exclude system folders from being encrypted. It encrypts files with specific file extensions such as:

.3gp, .7z, .accdb, .ai, .avi, .bmp, .cdr, .divx, .djvu, .doc, .docm, .docx, .eps, .fb2, .flv, .gif, .gz , .gzip, .jpeg, .jpg, .mdb, .mdv, .mkv, .mov, .mp4, .mpeg, .mpg, .ods, .odt. pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .psd, .pub, .rar, .raw, .rtf, .svg, .swf, .tar-gz, .tgz, .tiff,. txt, .webm, .wmv, .wps, .xlr, .xls, .xlsb, .xlsm, .xlsx, .zip, .zipx

The instant it finds these files, it encrypts them using the AES and RSA ciphers and afterwards, it appends the “.crypted” extension to every compromised file and then opens a text file named “READ ME!!!.txt” that contains the following message:

“What happened to my files?

All your important files were encrypted using strong RSA-4096 and AES-256 algorithms.

File decryption is possible only with the help of the encryption key stored by us.

What to do to get the encryption key?

To obtain the key, you must pay a ransom in the amount of about a thousand rubles (EXACTLY 0.10004672 in the Dash cryptocurrency at Dash address XvW7aLVhJbvqvjnt7zkngBowWRhUi1Xwin ).

After payment you must send your unique identifier to one of our mailboxes.

If we see that the payment has been made, we will send you a descrambler and encryption key.

Where to get the ID?

Your unique identifier:

Where is the guarantee that after paying the ransom I can recover my files?

You can send us an email with an identifier one encrypted file up to 5 megabytes.

We will decrypt it and will send you as proof that we can decrypt your files.

How to send Dash?

Dash can be sent using the following monitoring service for exchangers:

Or register on the Payeer website and exchange money for Dash on the stock exchange inside the website:

Or you can use itOther cryptocurrency exchanges

What will happen if I do not pay the ransom?

You can restore files only by decrypting them. No antivirus office will help you.

If payment is not made within three days, 20% of the encrypted files will be irretrievably destroyed.

If payment is not made within seven days, all encrypted files will be destroyed!

You can read about RSA and AES algorithms in Wikipedia.

This file is on your desktop, you can open it again to read this text.”

As usual, when dealing with file-encrypting malware, paying the ransom is definitely not recommended. So the best way to deal with it is by wiping it out of your computer and use whatever backup copies you have until a free decrypter is available.

For one, malicious email campaigns where crooks attach a seemingly legitimate file that actually contains malicious scripts used to initiate its attack in the system.
