Cryptojacking, a cyberattack, involves the unauthorized use of a victim's devices to mine cryptocurrency without their knowledge. Attackers employ methods like malicious websites injecting scripts, malware installation, and compromising cloud accounts to secretly utilize computing power. Detection involves monitoring for unusual CPU usage, high electricity consumption, and unfamiliar processes. Prevention strategies include browser extensions, antivirus software, careful monitoring, and securing cloud environments with multi-factor authentication and cloud security tools. The podcast episode "Crypto Hijacking: How It’s Done & How to Protect Yourself" by Edward Henriquez explores these aspects, also discussing future trends like AI-powered and IoT-focused cryptojacking.

Edward Henriquez's "Decoded: The Cybersecurity Podcast" episode on Shadow IT uses a newscast format to explain this hidden use of unapproved technology within organizations. The podcast defines Shadow IT as hardware, software, or services adopted without IT oversight, highlighting the risks it poses through unmonitored data and security vulnerabilities. It explores the reasons behind Shadow IT, suggesting it often stems from slow IT processes rather than malicious intent. The episode further details real-world impacts of Shadow IT leading to data breaches and offers practical steps for discovery, education, governance, and continuous monitoring to mitigate these risks. Ultimately, the podcast positions Shadow IT not as a threat itself, but as an indicator of unmet user needs and advocates for a balanced approach between security and enabling innovation.
