Every day any Internet user follows the links. It would be simply impossible to use the Internet without links. But links can be good and bad. Let's look at the signs of a good link and a bad link.
Let's start with potentially dangerous links:
1. If the link is received from a stranger.
Through any channel: mail, messenger, SMS, social network. Consider that such a link is already potentially dangerous and should not be followed. Yes, in order to infect your device with a virus, you will need to run or install something, but the danger here is this:
- The link can be saved in history and then someone from the users of your device will follow it, download the program and someone unknowingly clicks on the installation or launch;
- You yourself will switch to it later, do not notice and run the resulting virus.
Output: just don't follow links from unfamiliar places. Links from SMS messages are especially dangerous: as a rule, they are sent en masse in the hope that someone will go over and install a malicious application.
2. A strange link from a familiar subscriber.
For example, suppose you have a relative. Who you chat with every six months on WhatsApp. And then a link comes to you from him:
You believe that your relative sent you a message, download programm.exe, install it. And there is a virus.
Output: a link has come from a familiar subscriber with a big request to do something, then it is better to call the subscriber back and clarify whether he sent the link. In 99% of cases, your interlocutor has been hacked.
3. Link protocol is different from http or https
A classic web link starts with http or https (secure connection).
http://site.ru/document.html - example of a classic link
In addition to these two protocols, there are a couple of hundred more common and exotic protocols that can open any programs (for example, Telegram). If you are not familiar with the URL protocol, then it is best not to follow this link.
It's also worth taking a closer look at the end of the link. For instance:
https://site.ru/file.exe - executable file. If you accidentally launch it by clicking on such a link, you can pick up a virus. (you should also be wary of .bat, .exe, .bin).
https://site.ru/file.apk - executable file for Android: run it, you initialize the installation of the application.
4. Short links (vk.cc, tinyurl.com)
Their essence is that, for example, here is a link to a publication on my site: http://aitishkin.ru/kak-ochistit-kesh-na-kompjutere-s-windows-10/
Long? But it is clear what will be in it if you translate the transliteration: "How to clear the cache on a Windows 10 computer." If this link is shortened, then it will be like this: https://clck.ru/VR8vr. It will open the same thing, but you cannot understand what from the URL.
They are also potentially dangerous in that we do not know what content will open after visiting. What if he scares you or shocks you? Site owners use such services in 2 cases: count the number of clicks and shorten a long URL.
Output: any content can be hidden behind a short link - this is the danger.
5. Clickbait links
Typically, such links can be found on media sites.
The link text will be as attractive as possible for the transition. However, after clicking on such a link in 90% of cases, you will simply waste time, you can order yourself a “tool for treatment of all joints for 3 kopecks ", stumble upon shocking and obscene content or even become a victim scammers. Don't waste your time! Link text is also important.
To get infected with the virus, it is not enough to follow the link. You still need to do some action: confirm the installation of the application / browser extension / run the executable file. However, this can happen by accident. You will click mechanically. And that's all. Caught a virus. Of course, a modern operating system is reliably protected, but there are always loopholes! By the way! If you are using Windows 7 (or previous versions) and Android below version 9, then the risk of contracting viruses is great: the systems are outdated and no longer supported.
