Spearfishing and Whaling: Cybersecurity Threats

Introduction

• Spearfishing vs. Whaling: Both are targeted forms of phishing attacks.
• Analogies: Similar to fishing with a net vs. targeting specific fish with a spear or going for big fish (whales).

What is Spear Phishing?

• Definition: Targeted email attacks on specific individuals.
• Objective: Gain access to login credentials, confidential information, or deliver malware.
• Targets: Individuals within an organization, often as a conduit to larger data breaches.

Examples of Spear Phishing Attacks

• High-profile data breaches:
  • JP Morgan
  • Siemens
  • Target
• Method:
  • Gleaning login details or network credentials via phishing emails.
  • Extracting sensitive information or deploying malware.
• Smaller Companies at Risk:
  • Often targeted due to weaker security infrastructure.
  • Used as entry points to attack larger corporations.

Signs and Prevention

• Realistic Emails: Appear genuine with real-looking sender addresses and relevant subject matters.
• Common Tactics:
  • Emails asking for password resets or downloading security patches (malware disguised).
• Targeting Administrators: Can lead to extensive access to internal systems.

What is Whaling?

• Definition: Targeted attacks on high-ranking individuals (executives, board members).

Prevention Tips

• Vigilance Required:
  • Be cautious with emails requiring specific actions.
