CCT 365: Malicious QR Code Attacks and Digital Forensics Techniques Every CISSP Should Know [REPLAY]

Send us Fan Mail

One careless QR scan can quietly turn a “private” chat into a live wiretap. We start with a timely threat story: Russian APT-style actors abusing Signal’s linked device flow by pushing phishing links that contain malicious QR codes, so messages can be mirrored to an attacker device in real time. If you use Signal, WhatsApp, or Telegram at work, this is the kind of simple, human-triggered failure mode worth building into your security awareness habits.

Then we shift into CISSP Question Thursday with a rapid, practical run through CISSP Domain 7.1 style topics in digital forensics and incident response. We break down what comes first when handling digital evidence (forensic copy before analysis), how to examine a suspicious file without detonating it (static analysis), and what makes an incident report useful under pressure (a clear timeline of events and actions taken). We also cover insider threat artifacts, mobile device forensics tools like Cellebrite UFED, and why chain of custody is the backbone that keeps evidence credible from collection to court.

Along the way, we talk about root cause analysis, anomaly-based detection for network traffic, and why clear writing beats big jargon when you’re briefing executives, legal, or a board. If you want exam-ready thinking that also maps to real investigations, you’ll get it here.
