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
