What is Sherminator ransomware? And how does it execute its attack?
Sherminator ransomware is a data-encrypting malware discovered lately created to lock valuable files in a compromised computer. According to security experts, it is a new and improved version of Mr. Dec ransomware. It appends a custom extension, “[ID]XXXXXXXXX[ID]”, which contains the ID of its victims. It appears that it still uses the same encryption algorithm in encrypting files.
Once it invades a targeted computer, Sherminator ransomware will execute its attack by employing a data gathering engine where it is programmed to gather several types of strings in advance. The campaign metrics gathered are then used to optimize its attacks by registering the installed hardware components as well as certain operating system strings. The information gathering engine can also be used to harvest personally identifiable information about the users which could expose their identities. The personally identifiable information gathered includes name, address, telephone or mobile number, account credentials, passwords and more. The information harvested can be processed by a stealth protection module that protects the malicious executable file of this crypto-virus from any program that could interfere with its attack.
Additionally, Sherminator ransomware is also designed to modify the Windows Registry so it can achieve persistence. This means that the ransomware can automatically start in every system boot. After it achieves persistence, it will begin its encryption attack using the AES encryption algorithm. It mostly targets user-generated data like documents, database, images, videos, audio files and many more. And instead of using a generic rename template, Sherminator ransomware appends a random extension that goes like this “[ID]XXXXXXXXX[ID]” After the encryption, a file named “Decoder.hta” is generated which contains the ransom note stating:
“You are unlucky! The terrible virus has captured your files! For decoding please contact by email
[ID]JixrROGGh1PH6n1HK[ID] 1. In the subject line, write your ID.
2. Attach 1-2 infected files that do not contain important information (less than 2 mb)
are required to generate the decoder and restore the test file.
Hurry up! Time is limited!
Do not contact third parties for help, this may lead to the fact that you will be deceived and you will not receive your decoder.
