Top 10 Hacks in 2025 Part 2

In this episode of Technology Tap: CompTIA Study Guide, we explore a groundbreaking shift in cybersecurity threats focused on operational availability instead of data theft. Using five headline patterns from 2025, including a case where hospital scheduling systems were compromised, we highlight critical lessons for IT skills development and tech exam prep. Learn how these attacks challenge traditional security thinking and why ensuring system availability is vital for technology education and anyone preparing for CompTIA exams.

From there, we dig into poisoned updates and the uneasy truth that digital signatures prove origin, not intent. By compromising a vendor’s build pipeline, adversaries delivered “trusted” software that waited, watched, and embedded itself as infrastructure. Antivirus didn’t catch it; analysts comparing subtle anomalies did. We unpack practical defenses: behavior monitoring for signed code, attestation, SBOM use, and staged rollouts that verify after trust, not just before.

Next, the social engineering target shifts to the help desk at 24/7 casinos, where urgency is the culture. With real names, roles, and believable pressure, attackers turned resets into keys. The logs showed everything as legitimate because the system allowed it. We share fixes that work under fire: just-in-time privilege, second-operator verification for high-risk requests, audited callback flows, and playbooks that slow down when stakes go up.

Then the cloud nightmare: a leaked admin token, logging disabled, and entire environments—plus backups—deleted. No exotic exploit, just excessive privilege and shared control planes. We break down guardrails that change outcomes: least privilege everywhere, break-glass elevation with time limits, immutable backups in isolated accounts, and monitoring that attackers can’t silence.

All roads lead to the same insight: humans aren’t the weakest link; they’re the most overused control. Real resilience comes from systems that assume trust will be abused and still contain damage—observed trust, independent logging, and workflows that don’t require perfection from people under pressure. If you’re building or defending, this is your blueprint for 2026: reduce blast radius, verify behavior, and never make a human your final barrier.

If this hit a nerve or sparked an idea, follow, share with a teammate, and leave a quick review. Tell us: where does your organization rely on trust without verification?
