System hacking

It is defined as the compromise of computer systems and software to access the target computer and steal or misuse their sensitive information. Here the malicious hacker exploits the weaknesses in a computer system or network to gain illegal access to its data or take illegal advantage.

Phases of System Hacking

• Reconnaissance – Majorly used to gather data
• Scanning – Used to gather more intelligence on the data
• Gaining access – Takes control of one or more network devices to extract data.
• Maintaining access – Gains more data from the targeted environment
• Clearing tracks – Eliminate traces of detecting the attack.

How Hackers Perform System Hacking ?

A hacker can hack the computer system because the hacker knows the actual work of computer systems and software inside the system. For this, a hacker has information about the systems, networking, and knowledge of other areas related to computer science. Anyone who is using a computer and is connected to the internet is vulnerable to malicious hackers threats. These online villains generally use viruses, malware, Trojans, worms, phishing techniques, email spamming, social engineering, exploit operating system vulnerabilities, or port vulnerabilities to access any victim’s system.
