Most threats arrive by email
The e-mail it has always been considered one of the most common malware entry points. They can send us attachments that are actually viruses. For example, a simple image or a PDF that when we open them we are executing malicious code that has been designed to steal the keys or install a back door and allow cybercriminals to enter our computer.
But now an HP study confirms this theory and further claims that it is indeed one of the most common entry routes for malicious software in recent months. Therefore, if malware enters your computer, it is very likely that it is after opening a mail that you should not.
Specifically, in the first half of the year 75% of security threats have come through e-mail. It is undoubtedly a more than considerable figure, especially if we take into account that the email it is something that we use in our day to day constantly.
One of the threats that can arrive by mail is the ransomware. It is the type of malware that encrypts all the files on the computer and can even prevent us from turning on the computer. To fix the problem, the hacker is going to ask us to pay an amount of money to give the password. It is one of the most serious cybersecurity problems.
They still rely heavily on Word files and vulnerabilities to deliver malware. They usually throw a hook for the victim to open or download those documents that are actually going to contain the payload that the threat is going to execute.
Tips to avoid email malware
It is very important that we are aware of the threats that can arrive by email. Therefore, we must be prepared and keep the equipment always safe. The first and most essential is the common sense. In most cases these threats are executed after a mistake made by the user. For example, clicking on a link that comes to us by e-mail that is actually a scam, downloading a PDF or Word file that is nothing more than bait, etc. We must always recognize when an email is fake.
We must avoid interacting with emails that we do not know and do not really know if they are going to be a threat or not. Only then can we avoid falling into the trap. After all, cybercriminals are going to need us to do something, so if we don’t download that file or don’t open that link, we’ll have a lot to win.
But it will also be important to have security programs. A good antivirus, such as Windows Defender or using a third-party tool such as Avast, Bitdefender or Kaspersky, will help avoid malware. In case we make a mistake and download what we shouldn’t, you can lock that file and delete it. Keep in mind that there are different email providers and some have their own security methods.
In addition, it is convenient keep systems up-to-date. These email attacks often exploit security flaws. If we install all the patches and have the latest versions, these errors can be corrected.
Ultimately, email is the main entry point for malware. If we have our account protected, if we avoid making mistakes, we will have a lot of cattle to prevent threats from entering through this means.
