Introduction
As artificial intelligence systems grow more sophisticated, a critical question emerges: could they enable catastrophic cyberattacks against national critical infrastructure? GovAI’s recent report, “Assessing the Risk of AI-Enabled Cyberattacks on the Power Grid,” develops a quantitative threat model examining whether AI systems could enable a cyberattack on the US power grid causing $100 billion in economic damages—a threshold aligned with catastrophic risk definitions in several AI safety frameworks. The analysis reveals a surprising conclusion: the $100 billion scenario may be poorly suited for grounding AI safety policies, as the capability threshold is so extraordinarily high that systems meeting it would likely have transformative societal impacts far beyond this threat model.

You Should Know
- The Attack Surface: How AI Lowers the Barrier to Critical Infrastructure Attacks
The report identifies two primary attack pathways for catastrophic grid cyberattacks: physically damaging critical grid equipment and both triggering and sustaining cascading blackouts. What makes this analysis particularly sobering is that no single narrow technical bottleneck exists—rather, the binding constraint appears to be the operational capacity to coordinate diverse capabilities across dozens to hundreds of targets simultaneously.
AI dramatically lowers the barrier for adversaries by automating reconnaissance, vulnerability discovery, and attack execution. Researchers have demonstrated that using AI-generated queries on Shodan can locate live industrial systems—one query returned a Siemens SIMATIC device operating in run mode, unlocked, with accessible management pages. This represents a fundamental shift: previously complex attacks that required deep domain expertise can now be executed by less skilled actors with AI assistance.
Step-by-Step Guide: Securing OT/IT Network Perimeters
- Conduct Asset Discovery: Identify all OT devices on your network using Nmap:
nmap -sS -p 502,102,44818,2222 -T4 192.168.1.0/24 Modbus, IEC 61850, CIP, SSH
-
Implement Network Segmentation: Create VLANs isolating OT from IT networks:
Cisco IOS - Create VLAN for OT devices vlan 100 name OT_Network interface vlan 100 ip address 10.10.100.1 255.255.255.0
3. Deploy Industrial Firewall Rules:
Linux iptables - restrict access to SCADA ports iptables -A INPUT -p tcp --dport 502 -s 10.10.0.0/16 -j ACCEPT Modbus iptables -A INPUT -p tcp --dport 502 -j DROP iptables -A INPUT -p tcp --dport 102 -s 10.10.0.0/16 -j ACCEPT IEC 61850 iptables -A INPUT -p tcp --dport 102 -j DROP
4. Enable Port Security on Switches:
interface GigabitEthernet0/1 switchport port-security switchport port-security maximum 1 switchport port-security violation shutdown
- The $100 Billion Threshold: Why It Matters (and Why It Doesn’t)
The report uses the $100 billion threshold for two reasons: it aligns with quantitative definitions of catastrophic risk in AI safety frameworks, and prior scenario modeling has found such damages plausible for worst-case grid cyberattacks. However, the analysis reveals that for AI to meaningfully increase the risk of such attacks, it would need to automate most of the work of a large team of cyber-operatives with diverse skills—an extraordinarily high capability threshold.
This finding has profound policy implications. The $100 billion scenario may not be well-suited for triggering costly, scenario-specific mitigations because the capability threshold is so high. More critically, AI systems capable of enabling lower-skilled actors to launch such attacks would likely pose even more serious risks in other domains.

location /api/ {
proxy_pass https://scada-backend:8443;
}
}
- The $10 Billion Reality: More Likely, More Actionable
The report’s critical insight is that $10 billion grid cyberattacks appear qualitatively easier and may provide more useful capability thresholds for triggering mitigations. This distinction is crucial for cybersecurity professionals and policymakers: while catastrophic $100 billion attacks require extraordinary AI capabilities, lower-damage attacks are far more achievable and thus more urgent to defend against.
Participants in forecasting exercises estimated a 1% probability that a cyberattack against the US electrical grid would cause at least $10 billion in damages in 2026. This represents a concrete, actionable threat that demands immediate attention rather than speculative mitigation planning for extreme scenarios.
Step-by-Step Guide: SIEM Integration and Threat Detection
1. Configure ELK Stack for OT Log Aggregation:
filebeat.yml - collect Modbus logs
- type: log
paths:
- /var/log/modbus/.log
fields:
log_type: scada
processors:
- dissect:
tokenizer: "%{timestamp} %{level} %{service} %{message}"
field: "message"
target_prefix: ""
2. Implement Suricata IDS for Industrial Protocols:
suricata.yaml - enable Modbus and DNP3 detection app-layer: protocols: modbus: enabled: yes detection-ports: dp: 502 dnp3: enabled: yes detection-ports: dp: 20000
3. Windows Event Log Monitoring for SCADA Servers:
PowerShell - Enable advanced audit logging auditpol /set /subcategory:"Detailed Tracking" /success:enable /failure:enable auditpol /set /subcategory:"DS Access" /success:enable /failure:enable Forward events to SIEM wevtutil set-log "Microsoft-Windows-Sysmon/Operational" /enabled:true /retention:false /maxsize:1073741824
4. Automated Alerting with ElastAlert:
alert_rule.yaml - detect Modbus command anomalies name: Modbus_Write_Anomaly type: frequency index: scada- num_events: 5 timeframe: minutes: 1 filter: - term: log_type: "modbus" - term: modbus.function_code: "write_multiple_coils" alert: - "email"
4. Defending Against AI-Enhanced Reconnaissance
AI dramatically accelerates the reconnaissance phase of cyberattacks. Attackers use AI to generate Shodan queries, identify vulnerable industrial control systems, and automate vulnerability scanning at scale. The report’s finding that “lowering the barriers for top-tier states” would have an unclear effect on risk is particularly relevant here—while nation-states may already possess the required capacity, their willingness to launch such attacks outside active conflict appears significantly constrained by the prospect of retaliation or escalation.
Step-by-Step Guide: Honeypot Deployment and Threat Intelligence
1. Deploy Conpot ICS Honeypot:
Install Conpot git clone https://github.com/mushorg/conpot.git cd conpot docker run -d -p 502:502 -p 102:102 -p 44818:44818 mushorg/conpot Custom template for Siemens S7 docker run -d -p 102:102 -v $(pwd)/templates:/opt/conpot/templates \ -e CONPOT_TEMPLATE=s7-300 mushorg/conpot
2. Configure Shodan Monitoring:
Python script to monitor for new OT devices
import shodan
api = shodan.Shodan('YOUR_API_KEY')
Search for exposed Modbus devices
results = api.search('port:502 modbus')
for result in results['matches']:
print(f"Device: {result['ip_str']} - {result.get('org', 'Unknown')}")
Log to SIEM for threat intelligence
3. Implement Network Threat Hunting:
Zeek (formerly Bro) for OT protocol analysis
zeek -r capture.pcap /opt/zeek/share/zeek/site/local.zeek
Detect anomalous Modbus function codes
cat modbus.log | zeek-cut ts id.orig_h id.resp_h command | \
awk '{if ($4 > 100) print "Suspicious Modbus command: " $0}'
5. Cloud and AI Infrastructure Hardening
As AI infrastructure expands, it creates new attack surfaces. Federal assessments indicate that AI demand is no longer just a capacity challenge for the grid—it is now a cybersecurity challenge. The energy sector must secure AI models themselves, as adversaries can attack AI models, and the impacts of these attacks can cascade into physical consequences.
Step-by-Step Guide: Securing AI Model Pipelines
1. Implement Model Access Controls:
Hugging Face - restrict model access from huggingface_hub import login login(token="YOUR_TOKEN") Only allow specific users/groups Configure in Hugging Face organization settings

6. Vulnerability Exploitation and Mitigation in OT Environments
The CrowdStrike 2026 Threat Hunting Report reveals that 88% of vulnerabilities for which proof-of-concept exploit code became available were exploited within 48 hours. In OT environments, the window for patching is often measured in months or years due to operational constraints. This asymmetry demands defense-in-depth strategies that go beyond patch management.
Step-by-Step Guide: OT Vulnerability Management
1. Vulnerability Scanning with OpenVAS:
Scan for common OT vulnerabilities openvas-cli --target 192.168.1.0/24 --port 502,102,44818 \ --scanner "OpenVAS" --config "Full and fast"
2. Implement Application Whitelisting:
Windows - AppLocker for SCADA servers New-AppLockerPolicy -RuleType Exe -User Everyone -Path "C:\Program Files\SCADA\" -Action Allow Set-AppLockerPolicy -Policy $policy Linux - fapolicyd for RHEL fapolicyd-cli --file add /usr/bin/scada_executable systemctl enable fapolicyd systemctl start fapolicyd
3. Network-Based Anomaly Detection:

What Undercode Say
- The $100 billion grid cyberattack scenario is a poor policy trigger—the AI capability threshold required is so high that systems meeting it would pose far greater risks in other domains, making scenario-specific mitigations inefficient
- $10 billion attacks are the real priority—they are qualitatively easier to execute and provide more useful capability thresholds for triggering practical security investments and policy responses
The report’s analysis fundamentally reframes how we should think about AI-enabled cyber threats. Rather than focusing on extreme, low-probability scenarios, cybersecurity professionals and policymakers should concentrate on the $10 billion threat level where AI can realistically lower barriers for attackers today. The operational capacity to coordinate attacks across multiple targets remains the binding constraint—not any single technical vulnerability. This suggests that defensive investments should prioritize improving coordination, information sharing, and response capabilities across the energy sector rather than chasing hypothetical catastrophic scenarios. The finding that lowering barriers for top-tier states has an unclear effect on risk, given the constraints of retaliation and escalation, further reinforces that the most urgent threats come from non-state actors and lower-tier adversaries who would benefit most from AI-enabled attack capabilities. Organizations must therefore focus on raising the baseline of security across the entire critical infrastructure ecosystem.
Prediction
- -1 The $100 billion grid attack scenario will continue to dominate headlines and policy discussions, distracting from more realistic $10 billion threats that require immediate defensive investments and operational improvements
- +1 The report’s findings will accelerate the development of AI-specific security frameworks for critical infrastructure, with the Department of Energy’s CESER and Lawrence Livermore National Laboratory leading efforts to test and validate AI model resilience
- -1 Adversaries will increasingly exploit AI to automate reconnaissance and vulnerability discovery, with the 48-hour exploit window contracting to hours as AI-powered attack tooling matures
- +1 The emphasis on operational coordination as the binding constraint will drive new investments in sector-wide threat intelligence sharing and coordinated incident response capabilities
- -1 Energy AI systems trained on grid data, operational parameters, and infrastructure patterns represent significant intelligence value and will become prime targets for adversaries seeking to model and exploit grid vulnerabilities
- +1 Zero Trust architecture and micro-segmentation will become mandatory requirements for OT environments, driven by both regulatory pressure and the demonstrated ease with which AI can discover and exploit network weaknesses
