Ransomware protection & removal tool of 2021

Ransomware is a type of malicious software or “Malware” which can hold your data hostage.

    Top 3 targets of ransomware attacks are professional services firms, public sector, and healthcare business. The reason why ransomware can attack users is because the users download files from the unsecure or unreliable website, or the users receive phishing emails with the following titles, for examples;

  • Undelivered Mail Returned to Sender
  • Invitation to connect on LinkedIn

These phishing emails include an attachment in MS Word or Excel format, but if you carefully check the file name extension, you will find the “.exe” instead of “.docx” or “.xlsx”. Thus, if you open the attachment, your device can get infected with ransomware.

There are 2 main categories of ransomware attacks as follows.

  • Locker ransomware: It tries to access to your file containing important information such as name, ID card number, phone number, address and lock the file or encrypt it to prevent access from the owner.
  • Crypto ransomware: It encrypts the files to make them inaccessible and demands the owner to pay for decrypting them. Or it may send a URL “.onion” for the owner to chat and transfer money in bitcoin instead of directly transfer to a bank account. This is to keep the threatener safe from the transaction evidence.

Ransomware attack is like viruses but it has evolved more advance than viruses. For example, Maze Ransomware does not only lock the files but it can steal a user’s files and encrypt them. After that, Maze would threaten the victims with a message to publicly expose all data if the victims refuse to pay the ransom.  

There is another ransomware called “Samsam Ransomware” that has evolved to block users from accessing applications and make the backup files unable to be restored.

Another form of ransomware would attack servers enabling RDP (Remote Desktop Protocol) and access a super administrator account, then disable the anti-virus auto protect program. After that, it would steal the important data and install a backdoor in another computer, then delete the backup data.
