In simple words, hacking is a process of gaining illegal access to a device which may include mobile phones, computers, networks, social media accounts, or other authorized accounts. For example, hacking a computer's password and gaining access to it. Although this is an illegal process, it is not always done for bad deeds. The person doing hacking is called a hacker. These people have complete or in-depth knowledge about the equipment. Therefore, if a device is not strongly protected, it becomes easier for hackers to break the security and enter and hack the device. A hacker is responsible for detecting computer vulnerabilities and gaining access to the system. There are different types of hackers where some are known as official hackers because they perform the illegal processes to accomplish a legal task. On the other hand, there are unofficial hackers, who illegally hack a device without any official target. Thus, illegally hacking a computer or other device is a crime for which the hacker can be arrested in an illegal activity approach.

Hackers use various hacking techniques to hack the device:

virus
Trojans
insects
botnets
DDoS attacks (Denial of Service Attacks)
ransomware
Social Engineering and Phishing
malware-injection tool
cracking password
security patch missing
Browser Hijack, and more.
Thus, there should always be strong security measures and authorizations on the device to keep the device safe from any hacking crime. No weak points should exist in security especially for businesses, government sectors, and other private sectors.
