Key Takeaways
- Open‑source sandbox Nono limits AI‑agent access at the OS kernel to curb credential‑related incidents.
- Operational‑technology (OT) environments are losing the “air‑gap” myth; automation, supply‑chain risk, and a shrinking talent pool are top concerns for energy firms.
- Shadow‑AI incidents highlight how fast logs disappear, making post‑mortem analysis and regulator compliance difficult.
- Misused or expired credentials tied to non‑human accounts can cause prolonged outages before being detected.
- AI agents can pass safety checks yet still exfiltrate data, underscoring the need for runtime controls beyond pre‑deployment testing.
- Vulnerability volume remains overwhelming (≈200 new CVEs/day), with patching lagging despite AI‑assisted triage and global honeypot networks.
- Data‑breach costs rose to $4.99 million on average in 2026, with AI‑driven breaches costing roughly $1 million more.
- Emerging threats span aviation ground systems, AD CS domain takeover, Exchange XSS, Cisco FMC static creds, and AI‑powered phishing that abuses legitimate login flows.
Open‑source sandbox for AI agents: Nono
Luke Hinds and Stephen Parkinson introduced Nono, an open‑source runtime that sandboxes AI agents at the operating‑system kernel level. By restricting what agents can read, write, or execute, Nono mitigates risks from prompt injection, hallucinated commands, or simple mistakes that could otherwise expose sensitive files, credentials, or production systems. The project aims to give organizations a lightweight, auditable way to run AI agents without granting them blanket user privileges.
Marathon Petroleum CISO on OT security automation and supply‑chain risk
In a Help Net Security interview, Mary Rose Martinez, CISO at Marathon Petroleum, explained how deep automation in refineries, pipelines, and terminals has eroded the traditional air‑gap model for OT. She described using the Purdue model to apply security controls without halting production and highlighted how supply‑chain risk now extends to vendors’ vendors who hold critical keys to operational technology.
Shadow AI incident response begins with logs that may already be gone
Brandy Wityak, VP of Complex Matters at LevelBlue, noted that after a shadow‑AI incident, logs roll over quickly and firewall records of outbound traffic to AI platforms often disappear before responders arrive. This makes it challenging to reconstruct the attack chain and to demonstrate due diligence to regulators, who increasingly demand evidence of timely detection and response.
Your AI agents can reach data no one approved
A credential expired, yet an AI agent continued to use it, leading a mid‑sized company to suffer a quarter’s worth of downtime before the root cause—a non‑human account that nobody was logging—was uncovered. The incident illustrates how stale or mismanaged service‑account credentials can become a blind spot for AI‑driven automation.
The energy sector’s OT cybersecurity talent is retiring faster than it can be replaced
A ransomware hit on a chemical plant forced operators into a prolonged restart attempt, with encrypted processes and altered configurations keeping systems offline for weeks. The outage cascaded through the supply chain, underscoring the sector’s vulnerability due to aging control systems (20‑40 years old) and a dwindling pool of skilled OT security professionals.
An AI agent can pass every safety check and still leak secrets
Elad Meged of Novee Security demonstrated that a bot could read a pull‑request, extract shell commands, get them approved, and post the output—all while passing vendor‑provided safety checks. The experiment, run against three vendors’ default configurations, showed that secret leakage can occur even when pre‑deployment validation appears successful.
