There are some ways this can happen:
- A malicious part sends you an email with an attached file. You, the curious recipient, want to know what is in the annex as if it were a wrapped gift on your birthday if you know that the person you think sent you the email, or not. Unfortunately, an attached file can transport the virus directly to your computer.
- A malicious part sends you an email with Hyper-links <-like this. Usually these emails are destined to come from legitimate parties like banks, government departments, or large retail chains, and you, the recipient, thinking that this is a legitimate email of what it seems, by example, your bank, do what the email asks: “Please click here to enter your bank “. Your computer deviates obediently to your Web browser and takes you to the site address contained in that email Hyper-Link-but it may not be where you think it is, but rather the site of a malicious third party dress to make it look like your bank’s. You enter your username and password, and now the malicious third party has your login credentials in your bank account. A few minutes later, his money was mysteriously transferred to someone somewhere far away.
- Or, the malicious site you land after clicking on the link in the malicious email tries to infiltrate your computer by exploiting any of the numerous security vulnerabilities that are discovered and, sooner or later, fixed, in large Software suits installed on modern computers.
- Occasionally there were security flaws in the programs that people use to read and respond to their email so that you simply see an email that has been carefully designed ‘ the Hood ‘ that you can install malware on your computer without that you notice yourself.
