You will not be able to access your data if they have been encrypted by data encoding malicious program, which usually uses powerful encryption algorithms. Victims do not always have the option of recovering files, which is the reason why file encoding malware is so dangerous. There’s the option of paying the ransom to get a decryptor, but we don’t encourage that. Paying doesn’t necessarily result in decrypted files, so expect that you could just be wasting your money. What is stopping crooks from just taking your money, without giving you a way to decrypt files. In addition, that money would go into supporting their future ransomware or other malware projects.

Ransomware distribution ways

You can frequently run into ransomware added to emails as an attachment or on dubious download websites. Since there are a lot of users who aren’t cautious about opening email attachments or downloading from questionable sources, file encrypting malicious program spreaders don’t need to come up with more sophisticated methods. Nevertheless, some file encrypting malicious programs may be spread using more elaborate methods, which need more time and effort. Hackers don’t need to do much, just write a simple email that less careful users may fall for, attach the infected file to the email and send it to possible victims, who may think the sender is someone legitimate. You will commonly encounter topics about money in those emails, as those types of delicate topics are what people are more prone to falling for. It’s pretty often that you will see big names like Amazon used, for example, if Amazon sent an email with a receipt for a purchase that the person did not make, he/she would not hesitate with opening the attachment. In order to protect yourself from this, there are certain things you need to do when dealing with emails. Check the sender to see if it is someone you are familiar with. You’ll still have to investigate the email address, even if you know the sender. Those malicious emails also frequently contain grammar mistakes, which can be pretty obvious. Another pretty obvious sign is the lack of your name in the greeting, if someone whose email you should definitely open were to email you, they would definitely know your name and use it instead of a general greeting, such as Customer or Member. The data encoding malware could also infect by using unpatched computer software. All software have vulnerabilities but usually, vendors fix them when they become aware of them so that malware can’t take advantage of it to infect. Unfortunately, as as may be seen by the widespread of WannaCry ransomware, not all users install updates, for one reason or another. Situations where malware uses vulnerabilities to get in is why it is critical that your software are frequently updated. Updates can also be installed automatically.

How does it act

Your data will be encoded by ransomware soon after it gets into your computer. If you did not realize that something’s wrong at first, you will certainly know when your files are locked. Files which have been encrypted will have a file extension, which assists users in recognizing which ransomware exactly has infected their computer. In a lot of cases, data decryption might impossible because the encryption algorithms used in encryption might be quite hard, if not impossible to decipher. A ransom notification will be placed in the folders containing your data or it will appear in your desktop, and it ought to explain that your files have been encrypted and how you may decrypt them. The method they recommend involves you paying for their decryption software. Ransom sums are usually clearly stated in the note, but occasionally, crooks ask victims to email them to set the price, so what you pay depends on how much you value your data. For the reasons we have already mentioned, we don’t suggest paying the ransom. Try every other possible option, before you even think about complying with the requests. Maybe you have just forgotten that you have made copies of your files. Or, if luck is on your side, some malware specialist might have developed a free decryption tool. Malware researchers may be able to crack the data encoding malicious program, therefore a free decryptors could be released. Consider that before paying the ransom even crosses your mind. Using that money for backup may be more useful. If you had created backup before infection happened, you ought to be able to restore them from there after you eliminate Cosanostra ransomware virus. If you wish to avoid ransomware in the future, become familiar with means it might infect your device.
