How does ransomware spread

Email attachments, exploit kits and malicious downloads are the most frequent ransomware distribution methods. Quite a big number of file encrypting malicious programs rely on user carelessness when opening email attachments and more sophisticated ways are not necessarily needed. That doesn’t mean that distributors do not use more elaborate methods at all, however. All hackers need to do is use a well-known company name, write a generic but somewhat convincing email, attach the malware-ridden file to the email and send it to potential victims. Frequently, the emails will discuss money or related topics, which people are more inclined to take seriously. It is somewhat frequent that you’ll see big company names like Amazon used, for example, if Amazon sent an email with a receipt for a purchase that the user didn’t make, he/she would open the attached file immediately. You have to look out for certain signs when dealing with emails if you want an infection-free device. It is critical that you make sure the sender is dependable before you open the attachment they’ve sent you. And if you do know them, check the email address to make sure it matches the person’s/company’s legitimate address. Be on the lookout for evident grammar mistakes, they’re frequently glaring. Another typical characteristic is your name not used 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 typical greeting, like Customer or Member. It is also possible for ransomware to use unpatched software on your device to infect. Software comes with weak spots that can be used to infect a device but usually, vendors fix them. As has been shown by WannaCry, however, not everyone rushes to install those updates. It is crucial that you install those updates because if a weak spot is severe enough, Severe enough weak spots may be easily used by malicious software so make sure all your programs are patched. Updates can install automatically, if you don’t want to trouble yourself with them every time.

What does it do

Soon after the ransomware infects your computer, it’ll scan your computer for specific file types and once they’ve been identified, it will lock them. If you didn’t realize the encryption process, you’ll certainly know when your files cannot be opened. You’ll notice that all affected files have unusual extensions attached to them, and that helps users recognize what type of data encoding malicious program it is. It should be mentioned that, file decryption may be impossible if the file encrypting malware used a strong encryption algorithm. A ransom note will reveal what has occurred and how you ought to proceed to recover your data. If you believe the criminals, you’ll be able to restore data with their decryptor, which will not be free. The note ought to display the price for a decryptor but if that isn’t the case, you’d have to use the provided email address to contact the cyber criminals to find out how much you would have to pay. As we have already discussed, paying for a decryptor is not the wisest idea, for reasons we have already specified. Only consider paying as a last resort. Maybe you just don’t recall creating backup. For certain data encrypting malicious programs, victims can even locate free decryptors. Malware specialists are in some cases able to release free decryptors, if the ransomware is decryptable. Take that into account before paying the demanded money even crosses your mind. Using part of that money to purchase some kind of backup may do more good. If you had backed up your most essential files, you just remove Cosanostra ransomware virus and then proceed to data restoring. If you want to secure your computer from ransomware in the future, become familiar with probable means through which it could enter your computer.
