Hacking refers to compromising digital devices like computers and networks, usually for malicious purposes like financial gain. There are several types of hackers, including social engineers who use social skills to obtain passwords, biohackers who modify biology, crackers who break software codes to enable unauthorized use, phreakers who hack phones, and growth hackers who seek to expand businesses through questionable online tactics. Viruses are programs that can copy themselves and infect computers without permission. They spread through email attachments, downloads, removable drives, and networks. Common viruses include email viruses, worms, Trojans, and network viruses. People should use antivirus software, strong passwords, and safe downloading and email practices to prevent virus infections. The top sources of computer

2. What is hacking?
● Hacking refers to activities that seek to compromise digital devices, such as
computers, smartphones, tablets, and even entire networks. And while hacking
might not always be for malicious purposes, nowadays most references to
hacking, and hackers, characterize it/them as unlawful activity by
cybercriminals—motivated by financial gain, protest, information gathering
(spying), and even just for the “fun” of the challenge..

3. Types of HACKER…!
a) .Social Engineers
b) Biohacker
c) Crackers
d) Phreakers
e) Growth Hacker

4. 1.Social Engineers – These hackers don’t rely on gizmos or years of programming knowledge to
break into computer systems, yet they do it all the time. These whiz kids use social skills, good
theatrics, and a little bit of detective work to obtain passwords, credit card information, and other
devastating intel. Often targeting businesses, they can be a serious threat to be reckoned with, and
can even blackmail people with their findings.
2.Biohackers – Biohackers are very rare to come across, but they do exist. These are individuals
who work to bend the rules of normal biology and create new gizmos that work to improve the
body. A group of biohackers recently made the news when they created a night vision injection for
humans to use.
3.Crackers – Not to be misconstrued for the derogative term, crackers actually work to break the
keycodes that keep parts of programs unusable or uninstallable. By cracking the software code, the
users who download the software no longer have to pay in order to use the software. Cracked
software, also known as warez, is released under the idea that software should be free or open
sourced. Unfortunately, this is a nightmare for businesses that release software.

5. 1.Phreakers– While this term may sound like something you’d hear in a rap or EDM song,
phreakers are actually hackers who specialize in phones. In the 80’s, phreakers were the
ones who could do a DIY wiretap or get free calls on payphones. In modern ages,
phreakers are the people who create spyware for smartphones, intercept cellphone
signals on baby monitors, or do other similar acts. This form of hacking has intersected
with regular computer hacking now.
2.Growth Hackers – This is beginning to become a common name for people who may
use (or abuse) certain aspects of the internet in order to grow businesses or get a higher
SEO rank. If you choose to enlist the help of a growth hacker, make sure they’re white hat.
