How to avoid a ransomware contamination

This section will discuss how your machine may have become contaminated in the first place. It isn’t unexpected for ransomware to use more sophisticated methods to spread, although it uses simple ones more often. Spam email and malicious downloads are the popular methods among low-level ransomware authors/spreaders as not much skill is needed to employ them. By opening a spam email attachment is probably how you got the ransomware. An infected file is added to a kind of authentic email, and sent to all possible victims, whose email addresses they store in their database. If it’s your first time running into such a spam campaign, you may fall for it, although if you’re familiar with the signs, it ought to be rather evident. You can see particular signs that an email may be harboring malware, such as grammar mistakes in the text, or the sender’s email address being weirdly random. Usually, names of known companies are used in the emails because people are more likely to drop their guard when they come across a sender they’re familiar with. So, as an example, if Amazon emails you, you still have to check if the email address actually belongs to the company. If the email does not have your name, that itself is rather suspicious. If you receive an email from a company/organization you’ve dealt with before, instead of greetings like Member or User, your name will always be used. As an example, if eBay emails you, the name you have given them will be automatically included if you are a customer of theirs.

If you did not read the whole section, what you need to take from this is that you have to confirm the sender’s identity before you open email attachments. Also, don’t engage with ads when you’re visiting dubious pages. If you do, you may be taken to a page hosting ransomware. Whatever the ad may be offering you, try not to press on it. By downloading from unreliable sources, you may be accidentally putting your system at risk. If you’re commonly using torrents, at least make sure to read people’s comments before downloading one. There are also situations where vulnerabilities in programs may be used for the infection to be able to get in.
