How to Remove Dangerous Ransomware and Decrypt Files

Dangerous ransomware is a new crypto virus that only few anti-virus software can detect. It aims to infect the system in order to encrypt particular target data and demand ransom in exchange for the decryption key that is possessed by cyber criminals. In this article, we will report on all the impacts a threat of crypto ransomware type can deal with the system in case of infection. By reading about the most common ways of distribution, you could learn how to identify the danger of ransomware infection and prevent its malevolent impact. For all of you who are trapped by Dangerous ransomware, we have included an easy to follow removal guide supported by data decryption part. Keep reading and be safe.

More About Dangerous Ransomware Infection

Dangerous ransomware is named after the executable file DANGEROUS_RANSOMW.exe. Once this file is running on the system, the infection process starts, and Damage ransomware seizes target user data as well as essential Windows system settings.

We find the name of the threat trivial because there is almost no ransomware that isn’t dangerous. Even the Hidden Tear project created with educational purposes resulted in the emergence of numerous real crypto Trojans with minor adjustments like MafiaWare and RIP ransomware.

The harmless ransomware is the one that you stay away from.

Dangerous ransomware is supposed to scan all your computer drives searching for particular file types that are set in its target data list. Whenever it detects a match during the scan Dangerous ransomware implements encipher algorithm that replaces the code of the original file with a brand new code that can be reversed back to normal only with the help of a unique decryption key generated during the encryption process.

The decryption key is sent automatically to cyber criminals who blackmail abductees to pay a ransom in order to send them the key. Recovery steps offered by the crooks are usually placed in a TXT, HTML file or both. The files may be dropped on the Desktop or in a folder with encrypted files.

Currently, there is no information about an actual ransom note associated with Dangerous ransomware infection; however, we may suggest that the message urges all victims to send the ransom amount in Bitcoins to indicated BitCoin address and next send a confirmation email to cyber criminals at shown email address.

It is expected that cyber criminals should send back the decryption key that will help victims to restore encrypted data but don’t forget that negotiations with criminals are not fair at all. There is no guarantee that even after the money transaction is made and confirmed, the received decryption key will be working. It is better to reach out secure approaches to prevent further losses.

Presumably, Dangerous ransomware is developed to encrypt valuable data like MS Office documents, text files, images, videos, projects, PDF files and other regularly used file formats. The encryption is often realized with the help of powerful encipher algorithms like AES and RSA. Upon encryption, all corrupted files may get a malicious suffix appended at the end of their original filenames becoming completely unusable.

Some of the most targeted folder locations for dropping the malicious payloads associated with Dangerous ransomware are:

  • %UserProfile%
  • %UserProfile%\AppData\Roaming\
  • %AppData%
  • %LocalAppData%
  • %Temp%

By entering these folders you may find the malicious executable file DANGEROUS_RANSOMW.exe that triggers the Dangerous ransomware infection process. It is also likely that Dangerous ransomware implements modifications in Windows registries in order to enforce its encryption module each time the system is activated. So the following registry entries may be abused by the threat:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

Distribution Techniques for Dangerous Ransomware

The malicious payload may be hidden in regular MS Office document. This is possible via embedding malicious macro code which is supported by applications like Microsoft Office, Excel, and Power point. So once an infected document is opened the macros are run automatically. Then Dangerous ransomware can get access to the system.

Such documents may be archived in a ZIP file and then attached to a spam email.

Another way of DANGEROUS_RANSOMW.exe is via malicious links that may be spread around the web – spammed comments on websites, on social media post, shares, and even personal comments. They could also be part of malvertising campaigns.

Dangerous ransomware is also possible to be bundled with third party software installers.
