6. After getting hacked and caught by someone

7. Why we are not able to find bug?

8. Before After

9. Beware Traces left!

10. Random Instagram/ youtube influencer be like:
Ky hai hacking me lappu si to hacking hai

11. What is Cyber Security
It is a practice to take advantage of vulnerability or loophole in the
system.
Some times people do these activities for illegal work or for helping
others to stay safe.
To secure yourself from the evil peoples.

12. Skills required
• Problem solving
• Troubleshooting
• Computers basic knowledge
• Linux command line
• Networking
• Programming

13. Quick insights of basic terminologies
One who hack for illegal work, without
permissions.
One who hack for good reason with
permissions.
White Hat Hacker
Black Hat Hacker
Grey Hat Hacker
Hacks without permission but doesn’t harm
anyone.

14. Infected computer used to
harm, to perform DDOS
Malicious software which is
used to damage or harm
the system
Denail of Service is used to
send large number of
packets to the target
Distributed DOS is done with
multiple system and multiple
user with the help of botnet
A file infected by a malware
which can be used to take
access to the system
A fake url page sent to target
to gain credentials
Botnet Malware Exploit
DOS DDOS Phishing

15. A cryptographic term used to
convert a plain text into
unreadable text using keys
and algorithms
A cryptographic term used to
convert a unreadable text
into plain text using keys
and algorithms
Infected file through which
hacker can spy the
activities of target user
It creates a backdoor to target
system through which
attacker can get access into it
silently
It is an deadly attack which
encrypts the file
Used to change IP address
and our location
Encryption Decryption Ransomware
Spyware Trojan Horse VPN

17. Types of Penetration Testing
Black Box White Box Grey Box

18. Steps performed by an Ethical Hacker
It covers pre discussion
on all activities involved
in penetration test and
discussion what to and
where to test.
Gathering of information
and scanning for
vulnenrabilites.
Documentation of
vulnerabilities and the
evidence collected
during the test.
To find the exploit for the
found vulnerability.

21. Why Linux
Uses Less resources
and provides secured
environment
A better file system
and powerful than
windows
It is open source and
stable
Fully customizable from
each aspects and most of
cyber security tools are
created for linux

22. Kali Linux
A penetration testing
framework compatitable to run
on all devices like arm, pc,
desktop, mobile, tablets

23. Resources to practice
• Picoctf
• Tryhackme
• Hackthebox
• Overthewire
• Portswigger
• vulnhub

24. Enough theory let’s do
practicals😎

25. Frustrated windows user after shifting to Linux

26. Nmap- Network Scanner
A tool used to find the host, services, version, OS of target and other things.
