There are many attacks that hackers can launch to compromise security and something very common is that they take advantage of email. In this article, we are going to talk to you about a type of file that is being used a lot lately to infect computers. We are going to tell you what it is and what you should do to protect yourself and avoid security problems.
These are SVG files and they are using them to bypass detection by antiviruses. They send these attachments in emails, with the aim of making the victim fall into the trap. If you don’t know it, it is a file that is used to display images. Similar to JPG, for example, but in this case the images are created through lines and not pixels.
They use SVG files to infect computers
This SVG file has a series of texts that describe the image it should display. When you open it with the browser, it generates it. These vector images are automatically resized and do not lose their quality or shape. Now, they are using these types of files in malicious campaigns through email.
Specifically, they use it in Phishing campaigns. These SVG attachments can not only display images, but also HTML. This allows JavaScript to be executed, so they could launch forms where the victim will enter their data and passwords. In this way, they can obtain the credentials, access the system, infect the computer, etc.
For example, it is capable of displaying a fake Excel spreadsheet, with a login form. They can also pretend to be official documents, requests for information, etc. In these cases, they could invite the victim to click and download a file, which can introduce malware.
But why is it so dangerous? The reason is that they can bypass antivirus security. Unlike other files, it is more difficult for security software to detect and hackers have an opportunity there. That is why you must take extreme precautions at all times.
How to protect yourself
The most important thing is common sense. Be very careful with any file they send you in the mail, whether it’s an SVG file or any other. Be wary of any suspicious email that may reach you, as it could be a trap for cybercriminal hackers to steal your passwords or infect your computer.
It is also key that you have everything correctly updated. In many cases, attackers will exploit unfixed security flaws. When you install the updates, these patches will prevent them from accessing your system or executing any malicious file that you received by email.
Likewise, having a good antivirus is another security measure. Yes, it is true that it will not always help you avoid threats of all kinds, but it is one more tool that you should take into account to avoid problems.
In short, be careful with the files that arrive by mail. In this case, they are heavily using SVG files to infect devices and take control. Always make sure you have good protection. Acting quickly if your mobile or PC is hacked is essential.
