[01] EXECUTIVE SUMMARY

The agentic era has rewritten the threat model

In 2026, autonomous AI agents are initiating, reasoning about, and executing multi-step workflows — at machine speed, with the credentials of the users they represent. Your SIEM was built to detect anomalies in human behavior. An agent that executes 10,000 API calls in sequence looks entirely normal— even if every one is serving an attacker's objective.

The incidents we have documented share a common characteristic: the agent behaved exactly as designed, but its design had been subverted. An instruction buried in a web page. A MCP server serving malicious tool definitions. A payment routing rule planted three weeks before the fraud executed.

The full executive summary — including key findings, methodology, and strategic recommendations — is available in the complete report.

AI's integration into core business processes will present new threats from adversaries and from organizations themselves. Adversaries may seek to compromise trusted AI agents, effectively creating malicious insiders.

[02] THREAT LANDSCAPE

2026 agentic AI threat matrix

Twelve attack categories, classified by severity and prevalence across observed incidents and red team engagements.

critical
Prompt Injection & Indirect Injection
Malicious instructions embedded in data the agent processes — hijacking behavior chains at CVSS 9.6.
critical
MCP Server Exploitation
43% of public MCP servers vulnerable. Poisoned tool definitions, context capture, and RCE.
critical
Memory & RAG Poisoning
Persistent false beliefs implanted weeks before activation. Undetectable by traditional SIEM.
high
Agentic Supply Chain
Compromised npm packages, malicious agent skills, hijacked CI/CD — AI-accelerated at unprecedented scale.
high
Payment Agent Fraud
Agents with AP/treasury access manipulated to route payments to attacker-controlled accounts.
high
Blockchain Agent Key Theft
On-chain agents targeted for key extraction and unauthorized signing. Compromise is irreversible.
high
LLM-Enabled Malware
State-nexus adversaries embed LLM prompting in malware. Claude/Gemini CLI tools weaponized.
high
Multi-Agent Cascade Failures
Single compromised agent poisons 87% of downstream decisions within 4 hours.
medium
Secrets & Credential Exfiltration
API keys, OAuth tokens in agent context captured via injection or MCP server compromise.
medium
Non-Human Identity Abuse
Agent service accounts left over-permissioned, orphaned, and unmonitored.
medium
Shadow AI & Unsanctioned Agents
Employees deploy agents outside IT governance with corporate credential access.
medium
Denial of Wallet
Adversarial prompts induce 142× token amplification — catastrophic API cost exposure.

The full report includes 8+ additional incidents with technical IOCs, MITRE ATT&CK mappings, and detection guidance.

[04] DEFENSIVE ARCHITECTURE

Strategic recommendations

The report includes 7 strategic controls with implementation guidance. Here's a preview.

Secure AI Infrastructure
Monitor AI tool usage, enforce access controls, assess vendor security for all AI products and MCP servers.
Identity-First Architecture
Short-lived, task-scoped credentials per agent. Separate agent identity from human identity. Quarterly NHI reviews.
MCP Governance Layer
Centralized MCP gateway with authentication, payload logging, and context boundary policies.
Agentic Observability
Log every prompt, tool call, and output. Extend SIEM for agent behavioral drift detection.
Human-in-the-Loop
Mandatory approval for irreversible actions: send, publish, execute, transfer, delete.
Supply Chain Scanning
Pin AI GitHub Actions to SHA. Validate model provenance. Scan agent plugins and MCP servers.
