Exfiltration

Exfiltration (or Data Exfiltration) is the unauthorized transfer of sensitive data from a system or network to an external location. It’s one of the most serious outcomes of security breaches: attackers — or malicious insiders — can steal intellectual property, personal data, credentials, or financial records and move them outside the organization without permission.

In this video we unpack how exfiltration happens, the common attack vectors (malware and trojans, phishing and credential theft, misconfigured cloud storage, removable media, and insider threats), and the signs that data is being siphoned — unusual outbound traffic, unexpected compressed archives, or anomalous use of administrative tools.

You’ll learn practical detection and prevention strategies: Data Loss Prevention (DLP) tools, network monitoring and anomaly detection, endpoint detection & response (EDR), strong access controls and least-privilege policies, encryption (in transit and at rest), secure backups, and employee training to reduce phishing risk. We also cover incident response steps for suspected exfiltration: isolate affected systems, preserve logs, revoke compromised credentials, and notify stakeholders.

Whether you’re an IT admin, security student, or a general audience concerned about privacy, this episode gives you clear, actionable guidance to spot, stop, and recover from data exfiltration attempts. Protecting data is protecting trust — learn how attackers steal it and how you can stop them.
