Malware is one of the most widespread threats in the world of cybersecurity. For example, This software may reach systems via email or suspicious links.

These attacks include:

Viruses
worms
Trojan horses
Ransomware
spyware

When a system is infected, this malware begins stealing data or disrupting operations. Therefore, it is important to take preventative measures such as updating systems and using security software.

In addition, it is advisable to train employees to detect suspicious files to reduce the chances of hacking.

2. Phishing attacks

These attacks directly target the human element. For example, An employee may receive an email that looks official but contains a malicious link.
