✈️ $17,000 Gone Overnight – The United Airlines Scam Every Leader Must Understand

😱 A United Airlines passenger thought they were fixing a booking issue – instead, they lost $17,000 in hours.

🔎 Cybercriminals cloned support channels so well that the victim never realized they weren’t speaking with the real airline.

💡 Here’s the shocking part: the same tactic is already being used against employees, vendors, and executives. If one individual can be tricked so easily, imagine the risks inside an organization handling millions in transactions daily.

🚨 Attackers aren’t just sending clumsy phishing emails anymore. They use urgency, authority, and brand familiarity to manipulate human decisions. This isn’t a “tech” problem – it’s a human factor problem.

📊 For mid-market firms, one fraudulent transfer can create devastating financial and reputational damage. Prevention is no longer optional.

🔐 That’s where recurring simulation-driven training becomes critical. Employees need to recognize and resist these manipulations before real losses occur.

👉 AUMINT.io’s Trident platform equips businesses with ongoing, real-world attack simulations tailored to evolving threats.

💬 Are your teams ready for this type of attack? Or would they trust the fake “support line” too?

🚨 Executives and Celebrities Under Targeted Attacks

💡 Hackers are exploiting public data and social media to craft highly convincing schemes.

⚠️ Personalized social engineering attacks manipulate psychology – urgency, flattery, or fear – to bypass standard security.

📊 Even top-tier executives with robust IT defenses are vulnerable because human behavior remains the weak link.

🔍 Every interaction, post, or appearance can be mined to create targeted attacks that compromise individuals and organizations alike.

🔥 Mitigation requires proactive social engineering simulations and continuous employee training.

👥 AUMINT Trident simulates real-world attacks, tracks responses, and strengthens your human firewall before breaches happen.
