What is Umbrella Security ransomware?

Umbrella Security is yet another data-kidnapping malware that infects Windows computers. As soon as it gets on a victim’s PC, it runs executable files to start the encryption process. When the encryption is finished, all your personal files such as photo/video files, documents, archives, databases, and other files that may be of value to the user will become inaccessible. Later on, malefactors ask victims to pay the ransom for decryption software that can recover all their encrypted files. However, we don’t recommend you to pay them money as there is a high risk of getting scammed by virus authors. Therefore, you may be left without money and decryption software. Instead, try using the methods provided in this article to remove Umbrella Security ransomware and decrypt .aes files for free.

Once encryption is done, all user’s files will be renamed and marked with .aes extension. For example, file “IMG2054.jpg” will turn into “IMG2054.jpg.aes“. Afterward, the ransomware will drop a text file with a ransom note – “Please Read Me !!!.txt” that contains kidnappers’ demands. While the text in the ransom note may vary, the essence remains the same – cybercriminals demand 0.011 BTC ~ $519.08 from victims to regain data access. However, we do not recommend you do this, because no one can ensure that they send you the decryption tool even if the payment is transferred.

How to prevent your system from Ransomware?

No one is safe from infection with a virus that secretly encrypts your data. But in order to minimize this risk, you need to follow the rules:

1. Always make Windows updates on time and keep them up to date. Remember that these updates close the security holes of the system through which the virus can enter your computer.

2. The most efficient way to avoid data loss is of course to make a backup of all important data from your computer. It is enough just to synchronize the necessary folders with one of the cloud services, so as not to be afraid to see the text requiring the payment of bitcoins in exchange for a decryption key. It can be a cloud or a remote hard drive on the network. If you store all your files on the Internet, the likelihood of virus infection will be lower. Do not make copies to external hard drives, as this could damage them.

3. Since spam email is the most popular form of spreading ransomware-type viruses, the user should never open email attachments without first having scanned them with antivirus. Just clicking on the link or opening the attachment can damage the operating system (Windows) in a few minutes, damage important data, and infect other machines with the virus.

3. Ransomware-type viruses often crawl into a system using the Remote Desktop Protocol (RDP). RDP is a legitimate and useful feature that allows a user to take control of a remote computer or virtual machine over a network connection. But, at the same time, this is its Achilles’ heel as it’s poorly secured and has many vulnerabilities that can give hackers easy entry into the victim’s computer. In this case, we advise you to set a different from 3389 TCP port and use a more strong password. You can additionally protect yourself from virus penetration through an RDP connection with the help of a reliable firewall such as GlassWire’s Firewall

5. All previous methods do not matter if you do not have a reliable antivirus. The presence of anti-virus protection on your computer can prevent all these unpleasant surprises. Anti-virus protection will protect you from malware, money loss, time loss, invasion of your personal life. Now the antivirus market is so huge that it is difficult to make a choice in favor of one of them. If you have not decided who to give preference to, we suggest you familiarize with our Top 5 Antivirus Software for Windows
