How malware is distributed can vary greatly. There are many attacks that we can suffer. Many threats are present on the network. Hackers continually hone their techniques to achieve their goals. However, it should be mentioned that email is a widely used means of sending malware. In this article, we are going to talk about it. We will explain how to detect and control malicious Email Attachments that can reach us through a simple email.
Email Attachments are widely used to attack
Today all users have at least one email address. It is no longer just a means to stay in contact with other users. Still, it is also necessary to register on platforms; we use it to remember passwords that we have forgotten or use different services on the Internet.
Hackers use this medium to carry out their attacks. They can send an email containing malware in an email attachment. They can also carry out Phishing attacks to steal our credentials and passwords. It is, in short, an Internet service as used as it is dangerous if we do not take adequate measures and make mistakes.
With a simple email attachment, they could infect our computer. Therefore, it is important to avoid it, use common sense, and know how to identify when it can be a threat. Therefore, we will give a series of tips to explain how to detect malicious email attachments and what to do if we come across one.
How to detect malicious email attachments
This problem is widespread and can affect all users at some point. We can receive a normal email, without showing any danger, but it saves an attached file that can attack our system.
Observe the file extension
Something very important is to look at the file extension. There are certain extensions that we should avoid at all costs, such as .jar, .cpl, .bat, .js or .wsf. But other more common ones can be used by cybercriminals to carry out their attacks, such as a simple PDF or Word file. Also, the .exe files, although it is rare that a file of this type reaches us nowadays since the email provider will normally block it.
It is important, therefore, that we take a good look at the file extension. However, even in files that we consider safe, we should take precautions and avoid opening them if we also see any of the following suspicious points.
Who is the sender
This is also essential. Do we know the user who sends us that email? It may be a family member or friend who sends us something we are waiting for. It may be an unknown account, and we should be suspicious.
However, care must also be taken in this regard, since a known user has unconsciously been able to send this malicious email attachment. Your account may have been stolen, or your computer may be infected and forward emails of this type.
General content of the email
It is certainly another key point in determining if an email attachment we receive, can be a danger. We must observe details in the way of writing, if there are possible poor translations, etc.
Therefore we must look at the general content of that email to determine whether or not there is something that makes us suspicious. Any clue that indicates that we are facing a dangerous email.
They ask for some data
Sometimes we may receive an email asking for personal information. We may be invited to open that email attachment for more information. That should make us suspicious and show us that we are possibly facing a scam attempt.
Of course, you also have to look at the subject of the message. Are you urgently asking us to open that file? Maybe they indicate that we have won an award and that the information is in that PDF or Word that we have received? That also gives us clues that we may be facing a dangerous email attachment.
What to do if we receive a malicious email attachment
It is very important that if we receive a malicious email attachment, we take precautions. Something basic is never to arrive when you open it. We need to take care of our system, and something very negative would be to open a malicious file that could compromise our security.
It is also interesting not to interact in any way with that email. Not just downloading that file, but also responding or clicking on a link sent to us. In this way, we will avoid problems that may compromise our security.
The best thing if the case is to directly delete that email that we have received. Besides, if we want to guarantee that we will not receive more emails from that account, we can always block it. That way, we will have no problems if, at some point, we get caught off guard and open that file we receive.
