The most common way is usually through junk mail (or spam) that contains a malicious program that infects your computer, often without you realizing it, leaving your information and personal data at the mercy of hackers.
Below is a list of the possible files with which you can receive a virus on your corporate or professional mail:
- Office files: Especially Word, Excel and PowerPoint documents. These documents may contain embedded macros, a description of sequential steps to be followed that can activate viruses.
- PDF: Criminals often use these documents to target users with text asking them to visit unsafe pages.
- ZIP and RAR: These types of files allow the spread of a wide variety of viruses. The WinRAR function that these files have designs a series of commands for the malicious program to unzip in one of the folders on your computer without you often noticing.
- Images: IMG and ISO files are less commonly used to spread a virus, but in recent months there has been an increase in this technique.
Some tips to protect yourself:
- Multiple email accounts: It will help you, among other things, to verify your identity if one of your accounts is compromised.
- Do not publish your email address: If you have to, try to mask it.
- never answer: to a spam or junk mail.
- Beware of unsubscribe emails: Do not click on those links if they come from unknown sources or recipients.
- Update your browser and operating system: These are renewed to combat increasingly sophisticated malware.
