How does data encoding malware spread

Even though you can find special cases, a lot of ransomware tend to use the most basic distribution methods, like spam email, malicious adverts and fake downloads. More sophisticated methods are generally less common.

If you remember downloading a weird attachment from a seemingly real email in the spam folder, that might be why your files are now encoded. Once you open the infected file, the file encoding malware will be able to begin the encryption process. It is quite normally for those emails to contain money-related topics, which encourages many people to open it. When dealing with emails from senders you are not familiar with, be on the look out for certain signs that it might be dangerous, such as mistakes in grammar, strong encouragement to open the attachment. If the email was from a company whose services you use, they would have automatically put in your name into the email, instead of a regular greeting. Big company names like Amazon are often used as people know them, therefore are more likely to open the emails. It might have also been the case that you engaged with the wrong advert when browsing dubious websites, or downloaded something from a source that you ought to have avoided. Compromised sites may be hosting malicious advertisements so stop engaging with them. And when it comes to downloading something, only do it through valid websites. Sources such as adverts and pop-ups are notorious for being not trustworthy sources, so never download anything from them. If an application needed to update itself, it would not alert you through browser, it would either update automatically, or alert you through the software itself.

What happened to your files?

If you infect your system, you could be facing permanently encrypted files, and that makes a data encrypting malicious program so malicious. And it’ll take minutes, if not seconds, for all files you believe are important to be locked. If not for other signs, you can notice the data encoding malicious software when weird file extension appear attached to your files. Your files will be locked using strong encryption algorithms, which may be impossible to break. If you don’t understand what is going on, everything will become clear when a ransom note appears.
