This flow shows how a cyber threat appears, is identified by type, acts on the system, causes damage, and then is detected and responded to.

Execution Sample

Cybersecurity

Threats = ["Malware", "Phishing", "Ransomware", "DoS", "MitM", "SQL Injection"]
for threat in Threats:
    print(f"Detected threat type: {threat}")

This code lists common cyber threat types and prints each one as detected.

Analysis Table

Step	Threat Type	Action	Result
1	Malware	Infects system files	System compromised or slowed
2	Phishing	Tricks user to reveal info	User credentials stolen
3	Ransomware	Encrypts files for ransom	Files inaccessible until paid
4	DoS	Overloads network	Service unavailable
5	MitM	Intercepts communication	Data intercepted or altered
6	SQL Injection	Injects malicious code	Database data stolen or corrupted
7	End	No more threats	System needs recovery or protection

💡 All common cyber threats have been identified and their actions described.

State Tracker

Threat Type	Before Action	After Action
Malware	System normal	System infected
Phishing	User unaware	User credentials stolen
Ransomware	Files accessible	Files encrypted
DoS	Service available	Service down
MitM	Communication secure	Communication intercepted
SQL Injection	Database safe	Database compromised

Key Insights - 3 Insights

Why does ransomware make files inaccessible?

Ransomware encrypts files, meaning it locks them with a secret code. Until the code is removed (usually by paying ransom), files cannot be opened. This is shown in execution_table step 3.

How does phishing steal user credentials?

Phishing tricks users into giving their information by pretending to be a trustworthy source. This is a social trick, not a technical hack, as shown in execution_table step 2.

What happens during a Denial of Service (DoS) attack?

DoS floods the network or service with too many requests, making it unable to respond to real users. This causes service downtime, as shown in execution_table step 4.

Visual Quiz - 3 Questions

Look at the execution_table at step 5. What does a Man-in-the-Middle attack do?

A Encrypts files for ransom

B Overloads the network with traffic

C Intercepts communication between parties

D Tricks users into giving passwords

💡 Hint

Refer to execution_table row with Step 5 describing MitM action.

At which step does the system become unavailable due to network overload?

A Step 2

B Step 4

C Step 6

D Step 3

💡 Hint

Check execution_table for DoS attack causing service unavailability.

If phishing was removed from the list, how would variable_tracker change?

A User credentials would remain safe

B Files would be encrypted

C Network would be overloaded

D Database would be corrupted

💡 Hint

Look at variable_tracker row for Phishing showing user credentials stolen.

Concept Snapshot

Types of Cyber Threats:
- Malware: Infects and damages system
- Phishing: Tricks users to steal info
- Ransomware: Encrypts files for ransom
- DoS: Overloads network to block access
- MitM: Intercepts communication
- SQL Injection: Attacks databases
Each threat acts differently but harms security.

Full Transcript

This visual execution shows common types of cyber threats. The flow starts with a threat appearing, identifying its type such as malware or phishing, then acting on the system causing damage like data loss or service downtime. The execution table lists each threat type, its action, and result step-by-step. The variable tracker shows system state before and after each threat acts. Key moments clarify common confusions like how ransomware encrypts files or how phishing steals credentials. The quiz tests understanding by asking about specific steps and effects. This helps learners see how different cyber threats work and affect systems.
