How Clicking a Single Link Can Cost Millions | Ryan Pullen | TED

Summary

The speaker shares three perspectives on cybersecurity: investigating a costly ransomware attack, unethically breaching a secure building through social engineering, and nearly falling victim to a sophisticated phone scam. The underlying theme is how human behavior is exploited in cyberattacks, despite common perceptions of cybersecurity as solely technological. Small bits of personal data can be leveraged to create convincing narratives, manipulating individuals through empathy and trust. The speaker emphasizes protecting personal information and raising awareness of human vulnerabilities in the realm of cybersecurity.
