AI-Speed Ransomware Turns The First Hour Of Incident Response Into A Years-Long Risk Decision

The views and opinions expressed are those of Chris Patteson and do not represent the official policy or position of any organization.

Ransomware response used to be measured in days. Regulatory notification used to require 72 hours. The containment decision could wait for a call with leadership. None of that holds anymore. NIS2 in the EU compresses notification to 24 hours, with penalties matching GDPR: 2% of global revenue and potential personal liability for executives. AI-enabled tools are discovering exploitable zero-days in code that has been deployed for decades. And the decisions security leaders make in the first hour of an incident create consequences that stretch for years.

Chris Patteson is Director of Cybersecurity, GRC at a large pharmaceutical manufacturing organization and Co-Founder of the Enterprise Risk Quantification Institute. He also serves as a Chief Warrant Officer in the Louisiana Cyber Reserve, supporting cyber recovery and remediation for state agencies. His prior roles include Director of InfoSec at FedEx, where he was present during the NotPetya attack, and GRC leadership at Archer and LogicGate. He holds a patent in cybersecurity for device posture detection and isolation.

“A threat's ability to spread has changed. I have to make rapid decisions to preserve the resiliency of the entire operation,” Patteson says. “If you’re a distributed organization with lots of locations and you have to stop the spread once something is in your environment, that makes time of the essence.”

AI accelerates both sides

The exploit discovery window is collapsing, and two public cases show what that looks like: Claude Mythos Preview surfaced a 27-year-old vulnerability in OpenBSD’s TCP SACK implementation, while a separate Mythos review of WolfSSL generated multiple CVEs, including a certificate-forgery flaw affecting embedded environments. "It found an exploit that had been there for 27 years," Patteson says. "Nobody, no human, had found it. It was stringing together multiple techniques and tactics to create the exploit." The open-source software embedded in firewalls, IoT devices, and industrial equipment creates a risk surface that AI can map faster than security teams can patch.

The long tail nobody plans for

The first hour gets the attention. The years that follow do not. Patteson describes organizations that reinfected themselves by restoring corrupted backups without using a clean-room environment. Forensics teams that spent months determining whether attackers left backdoors beyond the initial encryption. And litigation that runs for years across partner obligations, privacy notifications, and regulatory enforcement.

"The initial cost of NotPetya to large corporations ran into the $400 to $700 million range," Patteson says. "But the long-term impact from litigation, re-architecting infrastructure, and regulatory follow-up could be up to double that." He warns that cyber insurance policies contain panel requirements buried deep in the terms, and failing to follow them can void coverage entirely. "Have your attorney in the room. Start looking through that and call law enforcement."

Legal privilege matters immediately. Patteson has seen organizations fire emails about an active incident without marking them privileged and without copying legal counsel, making everything discoverable in court. "One of my first calls, even before it's a true incident, is to get legal involved and start marking communications privilege and confidential," he says. For security leaders personally, D&O insurance is not optional. "In some of the stricter jurisdictions, they'll skip dealing with the company and come straight after you."

Pre-authorize the decisions before the incident

Patteson frames agentic SOC tools as an acceleration of what already exists, not a new category. "We've been doing SOAR for probably more than a decade," he says. "All you've done with agentic AI is boosted the capability of what we would have called orchestration." The question is whether organizations will let an autonomous responder make a containment decision: kill a firewall, isolate a location, shut down a network segment that costs a million dollars in lost production.

Those decisions have to be pre-authorized. "For these assets, we're going to have to make these decisions. How long are we willing to wait before we make that decision?" Patteson says. The business, security leadership, and operations all need to sign off on the triggers, the asset boundaries, and the acceptable cost before the incident begins.

He draws parallels to nuclear power plants that pull control rods automatically and aircraft with fault-tolerant failover systems. "Humans are not going to be able to respond fast enough," Patteson says. "I think we're going to see more of that coming to autonomous networks."
