You don’t need to be a millionaire to be attacked.

In the current context of cybersecurity, it is crucial to understand that vulnerability to computer attacks is not exclusively reserved for individuals with large amounts of money. Cybercriminality has become democratized, and anyone who uses the Internet becomes a potential target. Hackers often resort to techniques that allow them to take advantage of the personal information of a wide variety of users, regardless of their financial situation.

A paradigmatic example of this situation can be seen in the phishing attacks, where criminals send misleading emails that seem legitimate. These emails aim to steal personal information, such as passwords and credit card data. Unfortunately, many people fall into these traps without being aware of the risks. Through a single successful attack, a hacker could take control of an email or social media account, using the information obtained to compromise other associated accounts, often without considering the balance they may have.

It is important to note that personal information — such as phone numbers, addresses and other sensitive data — can be manipulated by cybercriminals to carry out frauds or extortions. Therefore, online security is an issue that concerns everyone. Attacks not only target professionals and entrepreneurs with high assets, but also common users who feel that their personal information does not represent a significant risk. Each individual must take appropriate measures, such as installing an antivirus and keeping their operating systems up to date, to protect against these cyber threats.

Evolution of Antivirus

The development of antivirus programs has been a continuous process that has been adapted as technology and digital threats evolve.
