🛡 Module 1: Cyber Threats & Internet Safety

1.1 Introduction to Cybersecurity

Definition & Scope
Cybersecurity is the practice of protecting devices, networks, applications, and data from unauthorized access, theft, and damage. It applies at all levels:

• Individuals: Safeguarding personal accounts, digital identity, and private files.
• Businesses: Securing sensitive client data, trade secrets, and operational systems.
• Government: Protecting national security assets, law enforcement data, and citizen records.

Importance

• For Individuals: Prevent financial fraud, identity theft, and reputation damage.
• For Businesses: Avoid legal penalties, customer trust loss, and operational disruption.
• For Nations: Prevent cyber warfare, espionage, and infrastructure sabotage.

Evolution of Cyber Threats

• 10 years ago: Mostly viruses, worms, and spam emails.
• Today: AI-driven phishing, ransomware, supply chain attacks, deepfake scams, and state-sponsored hacking.

Real Example:
In 2020, a major Indian e-commerce company suffered a data breach where 20 million user records (names, emails, and phone numbers) were leaked on the dark web, leading to massive trust issues and financial losses.

1.2 Common Types of Cyber Crimes

• Phishing & Spear Phishing: Fake emails or websites tricking you into giving passwords.
• Malware & Ransomware: Malicious software that steals or locks data until payment.
• Social Engineering: Manipulating human psychology to extract confidential data.
• Identity Theft: Using stolen IDs to commit fraud or crimes.
• Cyberstalking & Harassment: Continuous online threats or bullying.

Key Safety Tips:
✅ Always verify sender details before clicking links.
✅ Keep operating systems and apps updated.
✅ Install trusted antivirus software.

1.3 Safe Internet Practices

• Strong Passwords: Minimum 12 characters; mix of letters, numbers, and symbols.
• Two-Factor Authentication (2FA): Additional security step after password entry.
• Recognize HTTPS: Check for the lock icon before entering sensitive details.
• Avoid Unknown Links: Don’t download random files or click pop-ups.
• Public Wi-Fi Safety: Avoid online banking on public networks; use a VPN.

Example Case:
A Pune businessman lost ₹2.5 lakh after using public Wi-Fi for online banking without VPN protection.

1.4 Understanding the Web Layers

• Surface Web: Publicly available websites indexed by search engines.
• Deep Web: Private or restricted-access sites like academic databases, banking portals, and intranets.
• Dark Web: Hidden network accessed via special tools like Tor, often used for illegal activities.

Key Point:
Not all Deep Web content is illegal — it includes private, secure data like your email account.

1.5 Website Legitimacy Check

• WHOIS Lookup: Find out who owns a domain.
• SSL/TLS Verification: Secure sites use HTTPS encryption.
• Check Domain Age & Reviews: New domains may indicate scams.

1.6 Accessing Old or Deleted Websites

Module 2: Website & Network Understanding

Understanding how websites and networks work is crucial for cyber crime investigation. Attackers often exploit gaps in these areas, and knowing the structure, functionality, and weaknesses helps in tracing and preventing crimes.

2.1 Domains & Subdomains

• Definition:
  A domain is the main name of a website (e.g., example.com).
  A subdomain is a section or subset of the domain (e.g., blog.example.com).
  The full structure is often represented as:
  https://subdomain.domain.com/path
• Importance in Cybersecurity:
  Criminals register lookalike domains that closely resemble legitimate websites to trick users (e.g., paytm-secure.com instead of paytm.com).
• Real Example:
  During a phishing campaign, attackers used bankofindia-support.com to mimic the legitimate Bank of India site and steal login credentials.
• Key Tip:
  Always check the exact spelling of domains—subtle changes like replacing “l” with “1” can be a red flag.

2.2 Cloud-Based Websites

• Definition:
  Websites hosted on cloud platforms like AWS, Google Cloud, or Azure.
• Advantages:
  • Scalability – Handle more traffic without extra physical servers.
  • Accessibility – Access from anywhere with internet.
  • Data Backup – Automatic backups in case of system failure.
• Risks:
  • Data Breaches: Misconfigured cloud storage can expose sensitive data.
  • Downtime: Service outages can make a site inaccessible.
  • Unauthorized Access: Weak credentials can be exploited.
• Best Practices:
  • Use strong, unique passwords.
  • Enable two-factor authentication.
  • Encrypt sensitive data stored in the cloud.
  • Regularly audit security settings.
• Case Study:
  In 2021, a misconfigured Amazon S3 bucket led to the exposure of personal data of millions of users from an Indian e-commerce platform.

2.3 Finding Website IP Addresses

• Why It Matters:
  Knowing a website’s IP address can help investigators trace its hosting server, location, or block malicious servers.
• Methods:
  1. Command Prompt Method:
     • Open Command Prompt (Windows) or Terminal (Mac/Linux).
     • Type: ping website.com
     • The response will show the IP address.
  2. Online IP Lookup Tools:
     • Use sites like whois.domaintools.com or iplocation.net for detailed info.
• Practical Tip:
  Multiple domains can point to the same IP address, and attackers may use shared hosting to mask their activities.

2.4 Types of Internet Addresses

• IPv4:
  • 32-bit numeric address, e.g., 192.168.1.1.
  • Older format, limited to ~4.3 billion unique addresses.
• IPv6:
  • 128-bit alphanumeric address, e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
  • More secure, scalable, and future-ready.
• Key Difference: IPv6 supports exponentially more devices and offers better encryption features.

2.5 Email Header Analysis

• Purpose:
  Email headers contain hidden technical details that reveal the true source of an email.
• Steps:
  1. Open the email and find the full header option (varies by email provider).
  2. Look for the “Received From” and “Return-Path” fields.
  3. Identify the sender’s IP address and originating mail server.
  4. Check for mismatched domains or suspicious relay points.
• Example:
  An email claiming to be from PayPal but the “Return-Path” shows mailer@cheapoffer.biz indicates phishing.

Hands-On Practice for Module 2

1. Extract IP Address of a Website:
   • Find the IP of cyberinfo.space using both Command Prompt and an online tool.
   • Compare results.
2. Email Header Analysis Exercise:
   • Examine a sample phishing email.
   • Identify anomalies such as forged sender info or fake domains.

Module 3: Data Security, Encryption & Mobile Safety

3.1 Encryption Basics

Definition: Encryption is the process of converting readable data (plaintext) into an unreadable format (ciphertext) so that only authorized users can access it.

Types of Encryption:

• Symmetric Encryption – The same secret key is used for both encryption and decryption.
  • Example: AES (Advanced Encryption Standard) is used for encrypting files on hard drives.
  • Pros: Fast and efficient.
  • Cons: Key must be securely shared between sender & receiver.
• Asymmetric Encryption – Uses a pair of keys: a public key (to encrypt) and a private key (to decrypt).
  • Example: RSA, used in secure email communication and HTTPS websites.
  • Pros: No need to share the private key.
  • Cons: Slower than symmetric encryption.

Real-Life Example:

• WhatsApp uses end-to-end encryption to ensure only the sender and recipient can read messages — even WhatsApp itself can’t access them.

Key Tip: Always use strong encryption algorithms like AES-256 or RSA-2048 for sensitive data.

3.2 Data Protection Strategies

Why it matters: Data breaches can cause financial loss, legal trouble, and reputation damage.

Strategies:

1. Regular Backups:
   • Local Backup: External hard drive kept in a secure location.
   • Cloud Backup: Services like Google Drive, Dropbox (with encryption enabled).
   • Case: During the 2017 WannaCry ransomware attack, companies with recent backups could restore their data without paying ransom.
2. Role-Based Access Control (RBAC):
   • Only give employees access to data they need for their work.
   • Example: An HR staff member shouldn’t have direct access to company financial data.
3. Compliance with Privacy Laws:
   • GDPR (Global) – Protects personal data of EU citizens.
   • Indian IT Act & DPDP Act – Governs digital privacy in India.
   • Non-compliance can lead to hefty penalties and loss of customer trust.

3.3 Mobile App Threats

Risks from Third-Party App Stores:

• Many unofficial stores offer free or modified apps but inject malware or spyware.
• Case: Joker malware infected hundreds of Android apps, stealing SMS data and enabling premium service subscriptions without user consent.

Spyware in Fake Apps:

• Apps posing as “flashlight” or “photo editors” often hide malicious code.

Permissions Misuse:

• A calculator app asking for camera and microphone access is suspicious.
• Over-permission apps can record conversations, steal contacts, and track location.

3.4 Secure Mobile Usage

Best Practices:

• Screen Lock: Always use PIN, password, or biometric lock to prevent unauthorized access.
• Find My Device: Helps locate or remotely wipe a lost/stolen phone.
• Updates: Keep your OS and apps updated to patch security vulnerabilities.
• App Permissions Review: Go to Settings → Apps → Permissions and revoke anything unnecessary.
• Use Mobile Antivirus: Reliable options include Bitdefender, Kaspersky, and Norton.

Case Example:
A Mumbai lawyer avoided major data loss when her stolen phone was remotely locked & wiped via Google’s Find My Device feature.
