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

MaxiCrypt ransomware is a file-encrypting threat discovered by Michael Gillespie, a security researcher. This ransomware was first noticed on November 28, 2017 and is reported to arrive on the targeted computer as a corrupted Microsoft Word document. MaxiCrypt ransmoware is considered to be a mid-tier crypto-malware which is found to delete the shadow volume copies of the encrypted files and overwrites the original files to make it hard for its victims to recover the encrypted files.
MaxiCrypt ransomware uses AES cryptography in encrypting files and adds the [[email protected]].maxicrypt extension on each of the files it targets. It targets user-generated files like images, videos, documents, audio, and other popular file formats. It then delivers a ransom note contained in a text file named as How to restore your data.txt that reads as follows:
Your personal ID
Your documents, photos, databases, save games and other important data was encrypted.
Data recovery the necessary decryption tool. To get the decryption tool, should send an email to:
[email protected] or
[email protected]
In a letter to include Your personal ID (see the beginning of this document).
In the proof we have decryption tool, you can send us 1 file for test decryption.
Next, you need to pay for the decryption tool.
In response letter You will receive the address of Bitcoin wallet which you need to perform the transfer of funds.
If You have no bitcoins
* Create a Bitcoin wallet: https://blockchain.info/ru/wallet/new
* Purchase Bitcoin: https://localbitcoins.com/ru/buy_bitcoins or http://www.coindesk.com/information/how-can-i-buy-bitcoins (Visa/MasterCard, etc.)
When money transfer is confirmed, You will receive the decrypter file for Your computer.
After starting the program-interpreter, all Your files will be restored.
* Do not attempt to remove a program or run the anti-virus tools
* Attempts to decrypt the files will lead to loss of Your data
* Decoders other users is incompatible with Your data, as each user unique encryption key
As you can see, the ransom note starts with a demanding message that alerts victims about the encrypted files. It also provides victims with a personal ID number which is instructed to be sent to [email protected] or [email protected] in order to get the decryption tool. If you are one of the unlucky victims of this ransomware, contacting the crooks behind it and paying the ransom is definitely not recommended as you’ll probably end up losing more money but nothing will be done to your encrypted files. So the best option for now is to use whatever back copies you have of the affected files and wait until a free decryptor is released by security experts.
