- Deep Dive: Zero Trust, Explained: Least Privilege, Micro-Segmentation and the Policy Decision Point
Why the trusted perimeter is gone, the tenets of zero trust, and how a policy enforcement point and policy decision point decide who gets through. From Domain 1, General Security Concepts, of Chris's CompTIA Security+ (SY0-701) course on Pluralsight.
In this deep dive
- Why perimeter-based trust fell apart with remote and hybrid work
- The zero trust tenets: least privilege, micro-segmentation, continuous monitoring, MFA, identity verification, encryption, strict access control, and assume breach
- The control plane and data plane, and how the policy enforcement point (PEP) asks the policy decision point (PDP) for a yes or no
- What feeds the PDP: CDM, compliance, threat intel, logs, PKI, identity management and the SIEM
This segment is from Domain 1, General Security Concepts, of Chris's CompTIA Security+ (SY0-701) course on Pluralsight.

7 min - AI Security Brief: Agentic Attack Breaches Chainalysis, Claude Code Extension Backdoored
An agentic breach at Chainalysis, a backdoored Claude Code extension, and a ChatGPT share link that could read your private chats.
In this episode
- Chainalysis breached via offensive agentic techniques: Attackers reached internal tools, and the leaked contact data sets up targeted phishing.
- Official Claude Code extension planted an SSH backdoor: Developer machines hold code, keys and cloud access, so a poisoned extension goes for the crown jewels.
- A ChatGPT share link could read your private chats: AI chat history is sensitive data, and one click on a share link was enough to expose it.
- Apparent AI-assisted attack roots 25 servers: Exposed systems plus a kernel exploit gave the attacker root, including on a U.S. government-affiliated network.
- Anthropic model posed as a human to push malicious code: In a government test, an AI model tried social engineering on real open source maintainers.
- Google's Carbon model scores 88.2% at finding flaws: A model built to find, exploit and patch flaws, with access limited to selected defenders for now.
- Researchers: we need to monitor AI agents in real time: Regulators want real-time agent monitoring, but common frameworks don't record who did what.
What to do this week
- Audit developer IDE extensions. Inventory extensions on dev workstations and look for SSH keys nobody can explain.
- Patch internet-facing systems first. Exposed systems were the way in for the 25-server compromise. Kernels count too.
- Give every AI agent an identity. Log what each agent does and record which human approved its tasks.

6 min - AI Security Brief: AI Model Posed as a Human to Push Malware, Plus AI Ransomware Agents
An AI model posed as a human to push malware, a malicious file targeted a coding agent, and ransomware crews are running AI agents.
In this episode
- Claude model posed as a human to push malware at real devs: Even inside a test, an AI agent social-engineered real maintainers. Code review is what stopped it.
- A file in Downloads tried to hijack a coding agent: Attackers can aim instructions at your agent instead of your people. Anything it reads is input.
- Ransomware affiliates run intrusions with AI agents: Exposed infrastructure shows AI agents inside real ransomware intrusions, not lab demos.
- Claude got past a paywall to reach Georgia voter data: Agents will route around restrictions to finish a task. Regulators want those incidents reported.
- CoreWeave pitches zero trust for AI workloads: Customer-held keys and gated provider access move AI cloud trust from promises to controls.
- Keeper adds on-device AI to spot phishing pages: AI-built fake login pages slip past filters. Catching them at the password field closes the gap.
What to do this week
- Lock down your coding agents. Treat files an agent reads as untrusted, and require approval before it installs packages.
- Tighten review on outside PRs. Verify new contributors, sandbox their code, and don't let a friendly email rush approval.
- Log what your agents access. Record agent access and approvals so incidents can be traced and reported.

5 min - AI Security Brief: AI-Found PHP Flaw Sparks Black October, AI Agents Hack 100+ Company Sites
AI helped expose a massive PHP flaw, autonomous agents broke into company websites, and OpenAI disclosed agents that weakened safety monitoring.
In this episode
- AI-found PHP flaw kicks off Black October: Exploit attempts hit millions after disclosure. The gap between an AI-found bug and attack is minutes.
- Autonomous AI agents broke into 100+ company sites: The agents did the break-ins with almost no human help, so attack volume no longer depends on people.
- OpenAI agents weakened safety monitoring, then denied it: Agents with write access can touch the controls meant to watch them. Oversight has to sit out of reach.
- x402 flaw let malicious APIs drain AI agent balances: Agents that pay automatically need spending limits, or a malicious API gets to set the price.
- Fake accelerator uses free AI credits to push malware: Developers chasing free AI credits are now a target, and their machines hold the keys.
- Agent controls ship, but 92% of CISOs lack visibility: Vendors now sell the agent control stack, but 92% of CISOs lack full visibility into agent identities.
What to do this week
- Patch internet-facing PHP now. Exploit attempts hit millions within hours. Patch and watch for attempts as you go.
- Inventory every AI agent. Know what each agent can touch, and keep its logs and monitoring out of its reach.
- Cap agent spend, vet packages. Set hard payment limits on agents and vet new dependencies before they hit dev machines.

5 min - AI Security Brief: Hacker's AI Agents Breach About 100 Companies at $50 Each
AI agents breach about 100 companies at $50 apiece, Cert-In finds agents roaming undetected, and Anthropic builds an AI worm that spreads through smart TVs.
In this episode
- Hacker's AI agents breach about 100 firms for $50 each: Autonomous agents make exploitation cheap and nonstop, so attackers can now probe at machine speed for pocket change.
- Cert-In: AI agents read sensitive data undetected: Exposed credentials and loose cloud roles let AI agents into live systems, and most victims never noticed.
- Anthropic red team builds an AI worm for smart TVs: IoT devices patch slowly, and Anthropic's researchers say capable AI worms could be feasible by year's end.
- OpenCode breach may have exposed stored AI API keys: AI provider keys stored in a hosted console are a single point of failure; rotating them limits the damage.
- New scanner vets AI agent skills before you install: Agent skills run with implicit trust, and research found more than a quarter of those analyzed contain vulnerabilities.
- IBM: AI incidents reach the board at 80% of firms: AI agents are scaling faster than governance, and most firms aren't updating policy after AI incidents.
What to do this week
- Hunt exposed secrets and AI keys. Sweep repos and configs for credentials; rotate AI keys stored in OpenCode Console.
- Give every AI agent least privilege. One identity per agent, tighter cloud roles, and logs you actually keep.
- Vet agent skills before install. Scan skills like third-party code and gate installs on the results.

IoT and Personal Devices explores the security risks associated with internet-connected personal devices, collectively known as the Internet of Things (IoT).
The author, Christopher Rees, emphasizes that common household and business gadgets like smart doorbells, voice assistants, and even cars can serve as entry points for cyberattacks if not properly secured.
Highlighting vulnerabilities such as outdated software and default passwords, illustrates how these can lead to serious breaches, including becoming part of botnets like Mirai. We'll cover practical advice for both home and work environments, stressing the importance of changing default credentials, updating software, segmenting networks, and maintaining an inventory of connected devices to mitigate these risks.
