networks, and data
from malicious
attacks. 2

3. WHAT IS A
CYBER
THREAT
A cyber security threat
refers to any possible
malicious attack that
seeks to unauthorized
access to data and
modify or damage
information.

4. TYPES OF CYBER THREATS &
ATTACKS
Malware
Emotet
Denial of Service
Man in the Middle
Attack
Phishing
SQL Injection
Password Attacks 4

5. MALWARE
Malware is malicious software such as spyware,
ransomware, viruses and worms. Malware is
activated when a user clicks on a malicious link
or attachment, which leads to installing
dangerous software.
•Block access to personal Files (ransomware)
•Install additional harmful software
•Obtain Personal information (spyware)
•Makes system non-openable

6. EMOTET
An advanced modular banking Trojan that primarily
functions as a downloader or dropper of Trojans.

7. DENIAL OF SERVICE (DOS)
A denial of service is a type of cyber attack that floods a
computer or network so it can’t respond to requests.

8. MAN IN THE MIDDLE ATTACK
Occur when attackers insert themselves into a two-party
transaction, Once the attackers interrupt the traffic, they can
filter and steal data.
Common MITM Entry points are:
1. Unsecure public Wi-Fi
2. Malware has breached a device

9. PHISHING
Phishing is the practice of sending fraudulent communications,
the goal is to steal sensitive data like credit card and login
information or to install malware on the victim’s machine.

Fake
Advertisements

10. SQL INJECTION
A Structured Query Language (SQL) Injection is a type of
cyber attack that results from inserting malicious code into a
server that uses SQL.

Retrieving hidden data
Steal credentials
Access databases
Delete data

11. SOCIAL ENGINEERING
Social engineering is the term used for a broad range of malicious
activities accomplished through human interactions. It uses
psychological manipulation to trick users into making security
mistakes or giving away sensitive information.

15. OPERATIONAL SECURITY
It is a risk management process that encourages managers to
view operations from the perspective of an adversary in order to
protect sensitive information from falling into the wrong hands.
Identify your sensitive data
Identify possible threats
Analyze security loop holes and other vulnerabilities
Assume the level of risk associated with each
vulnerability
Get Counter-measures in place

16. CLOUD SECURITY
Cloud security, also known as cloud computing security, consists of a set
of policies, controls, procedures and technologies that work together to
protect cloud-based systems, data and infrastructure.
Data Security
Availability
Compliance
Governance
Access Management 16

17. INFORMATION SECURITY
It is a set of practices intended to keep data secure from
unauthorized access.
Confidentiali
ty
Integrity

19. ONCE INSIDE, THE HACKER CAN
DO
Modify logs
• To cover their tracks
• To mess with you
Steal files
• Sometimes destroy after stealing
• A pro would steal and cover their tracks so to be
undetected
Modify files
• To let you know they were there
• To cause mischief
Install back doors
• So they can get in again
Attack other systems

Malicious Links and
References
Have Destructive
intensions 22

27. THE NEED FOR CYBERSECURITY
Cybersecurity is important because it protects all categories of
data from theft and damage. This includes sensitive data,
personal Information, governmental and industry information
systems.
27

28. FUTURE OF CYBERSECURITY
28
Some cybersecurity experts agree with a report
by Cybersecurity Ventures and expect financial damages
from cybercrime to reach $6 trillion by the end of this
year. Industry studies show that cyberattacks are among
the fastest-growing crimes in the United States

29. RECENT CYBERSECURITY ATTACKS
29
Experian
 In August 2020, credit reporting agency Experian suffered a breach that
affected 24 million consumers in South Africa and more than 793,000
businesses.
o The stolen data was eventually secured and deleted
 A Hacker Leaded Data of 18 Companies
 One of the most significant cyberattacks that occurred in 2020 was
through a hacker known as Shiny Hunters.
o The hacker stole around 386 million user records
from 18 different companies

30. HOW TO KEEP YOURSELF SECURED
FROM DIGITAL ATTACKS
Use a full-service internet security suite
Use strong passwords
Keep your software updated
Manage your social media settings
Strengthen your home network
Enlighten Family members
Take measures to help protect yourself against identity
theft
Know that identity theft can happen anywhere
Know what to do if you become a victim

31. CONCLUSION
Though not all people are victims to cyber crimes, they
are still at risk. Crimes by computer vary, and they don’t
always occur behind the computer, but they executed by
computer.
