🛑 How Whaling Works (Step-by-Step Example)
1️⃣ Target Identification: Attackers research high-level individuals within an organization.
2️⃣ Personalized Attack: Cybercriminals craft a highly customized email or message, often using official branding and urgent language.
3️⃣Spoofing & Deception: The message appears to be from a legitimate source, such as a business partner, government agency, or internal colleague.

Why is This Important for Small Businesses & SOHOs?
SMBs and SOHOs are increasingly targeted in whaling attacks due to limited security resources and high financial stakes. A successful attack can lead to financial losses, reputational damage, and regulatory penalties. Implementing strong email security measures, employee training, and multi-factor authentication (MFA) can help mitigate risks.

🔹 Verify Requests: Always confirm financial transactions or sensitive data requests via a secondary channel.
🔹 Limit Public Information: Reduce the amount of executive contact details available online.
🔹 Use Multi-Factor Authentication: Adds an extra layer of security to accounts
