.CORP Files Virus – Distribution

There are several spread techniques that are probably used for the distribution of .CORP ransomware. Malsam is one of those techniques. It is used by hackers for the spread of malicious code via massive email campaigns. They usually embed their malware in files of common types and attach these files to email messages. In addition, emails are often disguised as legitimate businesses or services.

The last could be explained by the fact that their purpose is to trick you into opening the corrupted file on your device as this action triggers the execution of 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 that appear to be sent from your bank.
  • An online order confirmation note.
  • Receipt for a purchase.
  • Others.

Malware authors may be also using compromised software installers and infected websites to spread this nasty ransomware infection. These methods enable them to embed the ransomware payload to a app installer or inject it into a web page. Both cases could result in an automatic and unnoticed execution of this payload directly on a target system.

.CORP Files Virus – Overview

Once loaded on the system, .CORP files virus initiates a sequence of malicious actions that cause heavy damages over the whole system. Except the file that is designed to trigger the infection process, the ransomware is likely to establish additional malicious files on the system. These files may be located in the following folders:

  • %Roaming%
  • %Windows%
  • %AppData%
  • %Local%
  • %Temp%

With the help of some of the established malicious files, .CORP ransomware could evade detection and reach the main infection stage – data encryption.

An additional finding about the impact of this ransomware is that it adds specific executable files in the Windows startup folder. This process along with the process of infecting certain Windows registries such as Run and RunOnce sub-keys makes .CORP ransomware one of the first programs that load on each system start. In order to prevent this nasty side effect you should definitely check your registries for malicious values and erase them all if present.

According to further analyses of this .CORP ransomware sample, it is designed to detect infected device’s current language. This command is probably performed in favor of hackers’ statistic purposes. It could serve for the configuration of the ransom amount that may be different for each country.

At this point, it is clear that the ransom note associated with this Paradise version has the name $%%! NOTE ABOUT FILES -=!-.html. Here is the complete message it presents:
