Ransom note by Storm ransomware virus

Storm ransomware is a file-encrypting virus that is created with .net compiler. After encrypting files, it demands to pay the ransom and provides contact email address However, researchers say that this crypto-malware is not a huge threat.

Storm virus uses a hard coded password to lock files on the affected computer, so it should not be hard to guess it. Therefore, you should not be scared by the ransom note that tells that you need to pay for the decryptor. Third-party recovery software should be able to help you.

However, crooks made a terrible mistake. They provided an invalid Bitcoin address. Therefore, even if you would be one of those victims who would risk paying the ransom, you wouldn’t be able to do it. It goes without saying that after the attack, you should focus on Storm removal.

What is more, authors of Storm use Gmail email. Thus, this email might be blocked soon. Moreover, the identity of the hackers might be found as well. We believe that this ransomware is created by wannabe cyber criminals who lack programming skills and knowledge.

However, the virus mostly spreads with the help of malicious email attachments and once victim opens the obfuscated file, malware executable, which is based on Stub.exe, is downloaded on the system. It aims at the most popular file types, such as MS Office documents, pictures, databases and similar files.

Nevertheless, the virus is not a huge cyber threat; it might still affect numerous Windows OS processes. Therefore, you should not let it stay for a long on the system. Remove Storm ransomware using reputable malware removal tool, for instance Reimage.

The main ways how ransomware viruses spread

  • malvertising on legitimate and high-risk websites,
  • fake or illegal downloads,
  • exploit kits.[1]

The most popular method among cyber criminals is malspam. Hackers use social engineering tactics to trick users into clicking malicious content. Hence, you have always to double-check the information about the sender, look up for grammar mistakes and other suspicious details[2] before clicking links or opening documents.

Security experts from the NoVirus[3] note that downloading illegal or fake programs often lead to ransomware attacks too. So, you should stay away from insecure download sites. What is more, you should not visit high-risk websites and keep software updated.
