Email SPAM Is the #1 Tool For Hackers

Don't Fall for Sophisticated Phishing Attacks

Even careful users get fooled. Here's how to protect yourself.

Real Attack: The Punchbowl Invitation Scam

Leanne Soucek's Experience, June 2024

"I received a Punchbowl invitation from one of my very best friends yesterday and tried to open it with my gmail password and then my MSN password. Wrong!! Long story short: a hack. Someone/thing was using her email to look like it was from her, but she knew nothing about it. I had even checked to see if the Punchbowl email was correct."

What Made This Attack Sophisticated:

  • Appeared to come from a trusted friend
  • Used a legitimate service (Punchbowl)
  • Email address looked correct at first glance
  • Fooled even a careful, security-aware user

"Wow, am I grateful for you and your team, Craig. Just unbelievable what it takes to try to stay safe-r in these electronic times." — Leanne Soucek

And it gets worse—here's what it really costs ↓
