Introduction & Summary

India's rapidly expanding digital footprint and increasing reliance on cyberspace have simultaneously exposed it to a complex and evolving array of cyber threats and vulnerabilities. These threats range from common malware and sophisticated phishing scams to state-sponsored cyber warfare and insidious disinformation campaigns. Understanding the diverse types of cyber attacks, the advanced nature of cyber warfare, and the inherent vulnerabilities within India's cyber ecosystem is paramount for developing effective defensive and offensive strategies. This module provides a detailed typology of these threats, highlighting their modus operandi, and critically examines the weaknesses that adversaries exploit, from human error to legacy systems and emerging technologies.

5.2.1 Types of Cyber Attacks

Cyber threats manifest in various forms, each designed to achieve specific malicious objectives. Explore the common attack vectors:

Malware

Malicious software designed to disrupt, damage, or gain unauthorized access to computer systems.

  • Viruses: Self-replicating code attached to programs.
  • Worms: Standalone, self-spreading across networks.
  • Trojans: Disguised as legitimate, create backdoors.
  • Spyware: Secretly monitors user activities.
  • Ransomware: Encrypts files, demands ransom.
    • - WannaCry (2017): Global impact, exploited EternalBlue.
    • - NotPetya (2017): Wiper disguised as ransomware.

Phishing & Social Engineering

Tactics to trick victims into revealing sensitive information through deception.

  • Phishing: Deceptive emails/messages for credentials.

  • Lack of Awareness: Susceptibility to phishing, social engineering.
  • Weak Passwords: Easily guessable or reused credentials.

Software & Legacy Systems

Outdated and unpatched technologies are prime targets.

  • Software Vulnerabilities: Bugs and flaws exploited by attackers (e.g., Log4j), lack of timely patching.
  • Legacy Systems: Reliance on outdated hardware/software, especially in PSUs, unsupported, unpatched.

IoT & Cloud Risks

The expanding digital perimeter introduces new entry points.

  • IoT Devices: Proliferation of devices with weak default security, used for botnets.
