.boost Files Virus – Distribution
There are several ways which may be used for the distribution of this version of Dharma ransomware. One of those methods is known to be malwspam. It provides hackers the chance to spread corrupted files of common file types in massive email campaigns. The emails are usually disguised as legitimate ones. However, their purpose is to trick you into opening corrupted files with embed malicious code on your device and this way trigger the ransomware payload. A variety of common file types such as documents, PDFs, images could be transformed into carriers of ransomware code.
These files are often presented as the following:
- Invoices coming from reputable sites, like PayPal, eBay, etc.
- Documents from what appears to be the victim’s bank.
- An online order confirmation note.
- Receipt for a purchase.
The malware authors may be also using compromised sites to spread this .boost Dharma ransomware infection. This method enables them to upload the ransomware configuration file to a compromised web page and set its automatic execution after a registered visit of this page.
.boost Files Virus – Overview
An infection with .boost files virus begins when its payload is started on the system. Upon successful execution it enables the ransomware to plague large number of system components and reach the main stage which is data encryption.
In the beginning of the infection process it could drop or create additional malicious files that will support the completion of the attack. Some of these files may be located in the following system folders:
Among the malicious activities performed by .boost files virus are modifications of registry keys. By creating certain registry values in the Run and RunOnce Windows registry sub-keys it could set up its files to run automatically on each system boot.
These changes could be noticed when you enter the following registry sub-keys locations:
These sub-keys are used when the virus wants to load its ransom note on the screen. The note is dropped during the infection process. The note could be copied several times so that it could appear on your desktop as well as in folders with corrupted files.
.boost Files Virus – Encryption Process
Alike some of the previous versions (.combo, .arrow, .bkp, etc.) Dharma .boost crypto virus needs to utilize its built-in encryption module for the completion of its main purpose. It could be configured to transform target files with the help of one or two cipher algorithms one of which is the AES. Following encryption, valuable files become inaccessible due to essential changes of their code. Unfortunately, all of your important files could be affected by the ransomware including your:
- Audio files.
- Image files.
A visible trait of all corrupted files is the distinctive extension .boost that appears at the end of their names. In addition, all .boost files will have other two extensions appended to their names. As discovered by security researchers Dharma .boost ransomware uses the following rename pattern for files it encrypts:
- Original file name – original file extension – victim ID – hackers’ contact email – boost
For example, you could see how a file that was originally named project1.docx will appear like shown in the image below:
During the encryption process, the ransomware generates unique decryption key that supposedly could recover the original code of corrupted files. In order that hackers could extort a ransom from their victims, their threat is configured to transfer the key to their server immediately after the encryption stage. However, there is no guarantee that the generated key could restore data as only a single bug in the code could break it.
