File decryption even if you pay is not guaranteed so you could just be spending your money for nothing.

That money would also finance future activities of these crooks. Ransomware already did $5 billion worth of damage to different businesses in 2017, and that is just an estimated amount. People are attracted to easy money, and when victims pay the ransom, they make the ransomware industry appealing to those kinds of people.

Ransomware spread ways

Generally, data encoding malware spreads via spam emails, exploit kits and malicious downloads. Because people are quite negligent when they open emails and download files, it is usually not necessary for data encrypting malicious program spreaders to use more sophisticated methods. That doesn’t mean more elaborate methods aren’t used at all, however. All criminals need to do is add an infected file to an email, write a plausible text, and falsely claim to be from a trustworthy company/organization. Frequently, the emails will mention money, which people are more likely to take seriously. Criminals also prefer to pretend to be from Amazon, and alert possible victims that there has been some suspicious activity in their account, which would immediately prompt a person to open the attachment. There a couple of things you ought to take into account when opening files added to emails if you wish to keep your device protected. If you’re not familiar with the sender, look into them. Checking the sender’s email address is still essential, even if you know the sender. Grammar mistakes are also a sign that the email might not be what you think. You ought to also check how you’re addressed, if it’s a sender with whom you’ve had business before, they will always greet you by your name, instead of a typical Customer or Member. Weak spots on your computer Vulnerable programs may also be used as a pathway to you computer. All programs have weak spots but normally, software makes patch them when they are found so that malware can’t use it to get into a computer. Unfortunately, as as could be seen by the widespread of WannaCry ransomware, not everyone installs those patches, for various reasons. Situations where malicious software uses vulnerabilities to get in is why it’s so essential that you regularly update your software. If you don’t want to be disturbed with updates, you can set them up to install automatically.

What does it do

Your files will be encoded as soon as the ransomware gets into your computer. If you initially did not notice something going on, you will certainly know when your files are locked. All affected files will have an extension attached to them, which can help users figure out the file encoding malicious program’s name. It ought to be said that, it could be impossible to decrypt data if powerful encryption algorithms were used. A ransom note will be placed in the folders containing your data or it will show up in your desktop, and it should explain how you could recover files. What cyber crooks will suggest you do is use their paid decryptor, and warn that other methods could harm your files. If the ransom amount isn’t specified, you’d have to use the provided email address to contact the criminals to find out the amount, which may depend on how much you value your data. For the reasons we have mentioned above, paying isn’t the option malware specialists suggest. When any of the other option doesn’t help, only then you ought to even consider complying with the requests. Try to recall whether you’ve ever made backup, maybe some of your files are actually stored somewhere. Or maybe there’s a free decryption utility. Malware researchers are sometimes able to release free decryptors, if they are capable of cracking the data encrypting malicious software. Take that into account before paying the requested money even crosses your mind. Using part of that money to purchase some kind of backup might turn out to be better. And if backup is an option, you may recover data from there after you fix Cosanostra ransomware virus, if it is still present on your system. Try to familiarize with how a file encoding malware is spread so that you can dodge it in the future. Make sure your software is updated whenever an update becomes available, you do not open random files added to emails, and you only trust legitimate sources with your downloads.

If you aren’t knowledgeable with computers, you may unintentionally bring about additional harm when attempting to fix Cosanostra ransomware by hand. If you do not want to cause additional damage, go with the automatic method, aka an anti-malware tool. The tool is not only capable of helping you take care of the threat, but it may stop future ransomware from entering. Pick the malware removal program that would best match what you require, download it, and scan your system for the threat once you install it.
