Understanding Data Exfiltration: How Hackers Steal Sensitive Information

Data exfiltration sounds like a sci-fi term—but it’s very real and very dangerous. In this short, cybersecurity expert Michael Hamilton explains how attackers quietly extract your sensitive data once inside your network.

They don’t just break in—they take out. Whether it’s intellectual property, internal emails, or personal records, the goal is to steal and monetize your data.

If you’re catching them at exfiltration, you’re already several steps behind.
