Encryption and hashing you must understand.

Why this topic matters
- Protects data in transit and storage
- Weak crypto breaks entire systems
- Many breaches start with poor implementation

Encryption vs hashing
- Encryption: Two way
- Hashing: One way

Encryption basics
- Symmetric encryption:
- Same key for lock and unlock
- Fast
- Used for bulk data
- Example: AES
- Asymmetric encryption:
- Public and private key pair
- Slower
- Used for key exchange
- Examples: RSA, ECC

Where encryption is used
- HTTPS traffic
- VPN tunnels
- Disk encryption
- Database encryption

Hashing basics
- Converts data into fixed length value
- One way process
- Same input gives same output
- Common hash algorithms:
- MD5: Broken
- SHA-1: Broken
- SHA-256: Secure

Passwords and hashing
- Never store plain text passwords
- Use salted hashes
- Salt blocks rainbow tables

Real breach example
- LinkedIn lost 117 million hashes
- Used unsalted SHA-1
- Cracked within days

Digital signatures
- Prove authenticity
- Verify integrity
- Used in software updates

SSL TLS explained simply
- Browser verifies certificate
- Public key exchanged
- Symmetric key created
- Encrypted session starts

Common crypto mistakes
- Using MD5 for passwords
- Hardcoding keys
- Reusing encryption keys
- Rolling custom crypto

What you should do next
- Encrypt a file using OpenSSL
- Hash passwords using SHA-256
- Break weak hashes in lab
- Read TLS handshake flow

Web Application Vulnerabilities You Must Know

Why Web Apps Get Hacked
• Publicly exposed
• User input everywhere
• Weak validation

OWASP Top 10: Core Risks
1. SQL Injection
– Attacker injects SQL code
– Bypasses login
– Example: Input: ' OR 1=1 --, Result: Full database access
2. Cross Site Scripting (XSS)
– Injects malicious noscripts
– Runs in victim browser
– Types: Stored, reflected, DOM
3. Cross Site Request Forgery (CSRF)
– Forces user actions
– Exploits active sessions
– Example: Forced password change
4. Broken Authentication
– Weak login logic
– Session reuse
– Poor password policies
5. Security Misconfiguration
– Default credentials
– Open admin panels
– Debug mode enabled
6. Sensitive Data Exposure
– Data sent without encryption
– Logs store secrets
7. File Upload Flaws
– Uploading web shells
– No type validation
8. Command Injection
– Executes OS commands
– Example: ; ls /
9. Insecure Deserialization
– Executes malicious objects
– Leads to RCE

Real-World Breach Example
• Equifax breach
• Unpatched web framework
• Data of 147 million users leaked

How Attackers Think
• Control input
• Break trust
• Chain small bugs

What You Should Do Next
• Practice OWASP labs
• Break one vulnerability fully
• Read source code
• Fix the bug after exploit

SQL Injection, XSS CSRF

SQL Injection
• Application trusts user input
• Input merges with SQL query
• Example: SELECT * FROM users WHERE username='admin' AND password='123'
• Injection: ' OR '1'='1
• Result: Login bypass
• Impact: Data theft, deletion, full access
• How to detect: Error messages, unexpected login success, time delays
• How to prevent: Prepared statements, parameterized queries, input validation

Cross Site Scripting
• Malicious noscript runs in browser
• Example: Input <noscript>alert(1)</noscript>
• Stored in database, executes for all users
• Impact: Session hijacking, credential theft, page defacement
• How to prevent: Output encoding, Content Security Policy, input sanitization

Cross Site Request Forgery
• User performs unwanted action, session already active
• Example: Hidden request changes email, user clicks malicious link
• Impact: Account takeover, unauthorized transactions
• How to prevent: CSRF tokens, SameSite cookies, reauthentication

Hands-on practice plan
• Set up DVWA
• Exploit each bug
• Fix the code
• Retest

Beginner mistakes
• Learning attack only
• Ignoring defense
• Skipping logs

What you should do next
• Write secure login code
• Review past breaches
• Practice daily labs

Ethical Hacking Workflow and Core Tools

Ethical hacking means authorized security testing to find weaknesses before attackers, following a legal scope.

- Standard Hacking Workflow
- Reconnaissance: collect target info (domains, IPs, tech stack); tools: whois, nslookup
- Scanning: identify open ports and services; detect versions; tools: nmap
- Enumeration: extract users, shares, endpoints; deep system insight
- Exploitation: use vulnerabilities; gain access; tools: Metasploit
- Privilege escalation: move from user to admin; abuse misconfigurations
- Post exploitation: maintain access; collect evidence; clean test artifacts

- Key Tools to Master
- Nmap: port scanning, service detection, noscript scanning
- Metasploit: exploit database, payload handling, session control
- Burp Suite: intercept HTTP requests, modify parameters, test auth logic
- Nikto: web server scanning, finds misconfigurations
- Gobuster: directory brute force, hidden endpoints
- Hydra: credential testing, detects weak passwords

- Beginner Mistakes
- Skipping scope definition
- Running exploits blindly
- Ignoring logs

- What You Should Do Next
- Perform full lab attack flow
- Write report for each step
- Practice ethical rules
- Learn defensive fixes

Password Attacks, Sniffing, Spoofing

Why These Attacks Work
• Weak passwords
• Unencrypted traffic
• Poor network controls

Password Attacks
Brute Force: Tries all combinations, targets short passwords (e.g., admin123)
Dictionary Attack: Uses common word lists, faster than brute force
Credential Stuffing: Uses leaked credentials, high success rate
Password Spraying: One password across many users, bypasses lockouts

How to Defend
• Strong password policy
• Account lockout
• Multi-factor authentication

Sniffing
• Attacker captures packets, reads unencrypted data
• Occurs on public WiFi, open networks
• Tools: Wireshark, tcpdump
• Impact: Session hijacking, credential theft
• Defense: HTTPS everywhere, VPN on public networks

Spoofing
ARP Spoofing: Fake MAC to IP mapping, intercepts traffic
DNS Spoofing: Redirects to fake sites
IP Spoofing: Hides attacker identity
• Defense: ARP inspection, DNSSEC, network monitoring

Real Incident Example
• Public WiFi attacks at airports, captured email logins

Beginner Mistakes
• Testing on real networks
• Ignoring encryption
• Weak lab setups

What You Should Do Next
• Crack weak hashes in lab
• Sniff traffic with test VMs
• Implement defenses

Threat modeling, risk management, incident response

Why this matters
• Attacks are inevitable
• Preparation decides damage
• Professionals think before tools

Threat Modeling
• Identifying what can go wrong
• Understanding attacker paths
• Protecting what matters most

Key questions:
• What are we protecting
• Who can attack
• How can they attack
• What happens if they succeed

Common methods:
• STRIDE model
– Spoofing
– Tampering
– Repudiation
– Information disclosure
– Denial of service
– Elevation of privilege
• Assets to protect:
– User data
– Credentials
– Servers
– APIs
– Source code

Risk Management
Risk formula: Risk = Threat × Vulnerability × Impact
Risk types:
• Low: Minor impact
• Medium: Business disruption
• High: Legal or financial damage

Risk treatment options:
• Mitigate: Fix vulnerability
• Accept: Low impact risk
• Transfer: Insurance
• Avoid: Remove feature

Security controls:
• Preventive: Firewalls, MFA
• Detective: Logs, alerts
• Corrective: Patches, backups

Incident Response
• Data breach
• Malware infection
• Unauthorized access
• Service outage

Lifecycle:
• Preparation
• Identification
• Containment
• Eradication
• Recovery
• Lessons learned

Real example flow:
• Alert triggers
• Logs analyzed
• Infected system isolated
• Malware removed
• Passwords reset

Why documentation matters:
• Legal compliance
• Audit readiness
• Future prevention

Frameworks
• NIST
• ISO 27001

Beginner mistakes
• No incident plan
• Ignoring alerts
• Fixing without root cause
