A cyber attack is any unauthorized access to an IT network or digital devices for malicious purposes such as data theft, malware injection, or the initiation of additional attacks.
Cyber attacks have been a threat since the dawn of the digital era. The first cyber attack occurred in 1989 by Joseph Popp. This was a ransomware attack that was spread with infected floppy disks and deployed through a malware called the AIDS trojan.
Since then, many cyberattack methods have been developed and continue to be developed as the attack surface expands.
