“Living off the AI” describes attackers exploiting AI assistants, agents, credentials, and integrations an organization already trusts—much as living-off-the-land attacks misuse ordinary tools already inside a victim’s environment. The key risk is not simply that a model gives a bad answer: a compromised account, malicious content, or stolen key can let an attacker make use of an AI system’s existing access. The phrase is a useful way to explain evolving tradecraft, not a standardized incident category with an established global prevalence rate.
What does “living off the AI” mean?
Living off the land means abusing legitimate tools available in a target environment rather than relying only on conspicuous, unfamiliar malware. Living off the cloud extends that idea to trusted cloud services and identities. The AI-era version applies the same logic to assistants, agents, models, API credentials, and the connections that let AI systems retrieve information or take action.
In a February 6, 2026 SecurityWeek article, Etay Maor, VP of Threat Intelligence at Cato Networks, described the progression as tradecraft mapped onto assistants, agents, and the Model Context Protocol (MCP) ecosystem. That is expert commentary and framing, not a formal classification from a standards body. The practical point is that an AI feature can become another route through an organization’s existing permissions and workflows.

How can attackers use an organization’s AI?
AI can lower the effort needed to research a target, compose convincing messages, write or troubleshoot scripts, and process information. It can also become useful after an intruder gains access, particularly when an assistant can search internal material or an agent can call authenticated business tools. The following mechanisms should not be conflated:
| Access path | What the attacker may do | What the evidence says |
|---|---|---|
| Compromised user account | Use the account’s legitimate access to query an enterprise AI platform or internal assistant, potentially extracting useful operational context or asking for help with a task. | Palo Alto Networks Unit 42 describes valid-credential misuse and an insider case in which an AI assistant was used to investigate systems, generate a denial-of-service script, and troubleshoot it. These are Unit 42 observations, not a claim that this pattern is common across all organizations. |
| Malicious instructions in content | Place instructions in a document, email, web page, or other material that an AI tool processes, attempting to steer the agent into revealing data or taking an unauthorized action. | The Center for Internet Security (CIS) describes these prompt-injection risks. The Cloud Security Alliance’s AI Safety Initiative (CSA) calls abuse of an agent’s authenticated connections “Living Off the Agent” and identifies lateral movement as a concern. |
| Stolen AI API key or token | Use a victim’s credentials to consume AI services at the victim’s expense, resell access, or act under a legitimate customer identity. | Anthropic’s September 2026 threat-intelligence report describes stolen credentials in activity associated with ShinyHunters. Anthropic says the keys were taken from its customers’ environments and that Anthropic’s own systems were not compromised by that actor. |
| AI-assisted attacker work | Use a model to support reconnaissance, social engineering, scripting, troubleshooting, or extortion, without necessarily targeting an AI system itself. | Unit 42 and Google Threat Intelligence Group (GTIG) report observing these kinds of uses. They are examples of AI supporting operations, not evidence that AI caused the underlying intrusion. |
Agents make permissions especially important. An assistant limited to summarizing a user-selected document has a different risk profile from an agent that can read broad internal data, run code, edit records, or trigger workflows through authenticated integrations. An agent’s access can turn a successful prompt injection or compromised identity into a route to other connected services. In its May 19, 2026 note, CSA summarized an analysis of 21 documented multi-stage agentic AI incidents from 2025–2026 and reported lateral movement in eight. That is a selected incident analysis, not a prevalence measure for deployed agents.
What is documented—and what is not?
Threat reports describe real operational uses, but they do not establish that AI is responsible for most breaches or provide a single comparable global rate. Their findings have different populations and scopes:

- Unit 42: Palo Alto Networks says it responded to more than 750 major cyber incidents in 2025. In its 2026 report, identity weaknesses played a material role in almost 90% of its investigations. The report also says 87% of intrusions in more than 750 incident-response engagements involved activity across multiple attack surfaces, nearly half (48%) involved browser-based activity, and preventable gaps materially enabled intrusion in more than 90% of breaches. These are Unit 42 investigation figures, not global attack rates. Unit 42 describes AI as reducing friction across reconnaissance, social engineering, scripting, troubleshooting, and extortion, while familiar weaknesses—including excessive identity trust, incomplete telemetry, inconsistent controls, and third-party connectivity—remain central.
- Anthropic: Its September 2026 report describes suspected state-sponsored, financially motivated, and politically motivated actors using Claude in operations. In some cases, Anthropic says operators gave AI broad goals and used it to evaluate environments, write and execute scripts, summarize information, and iterate, including orchestration and multi-agent workflows. These are Anthropic’s observations of activity involving its service and investigations, not a universal account of AI-enabled cyber operations.
- Google Cloud and Mandiant: GTIG observed AI use for productivity, especially in reconnaissance, social engineering, and malware development. M-Trends 2026 also describes AI-themed lures, theft of AI application credentials, malware querying large language models, and a Mandiant-investigated credential stealer using a local AI command-line tool to locate GitHub and NPM tokens. Mandiant says it did not consider 2025 the year breaches were directly caused by AI in the cases it summarized; fundamental human and systemic failures remained the dominant explanation. Its metrics concern Mandiant Consulting targeted-attack investigations from January 1 through December 31, 2025.
These findings can coexist: AI may help attackers work more efficiently, and AI-connected systems may introduce new paths, while weak identity controls and other systemic failures continue to enable intrusions. Unit 42’s Sam Rubin put the productivity point this way: “AI didn’t make the attacker smarter; it just made them look professional enough to be dangerous.”

Why prompt injection is a security issue
Prompt injection occurs when instructions embedded in material an AI tool reads influence how it responds or acts. The material may be an email, document, web page, or other data source. If an agent treats untrusted content as instructions and has broad permissions, an attacker may try to make it disclose information or use a connected tool in an unintended way.
CIS’s April 1, 2026 announcement of its prompt-injection report lists possible outcomes including data theft, unauthorized actions, and persistent instruction poisoning. It is not accurate to infer that every injection succeeds: the outcome depends on the system, the content it can access, its permissions, its safeguards, and whether an action is checked before execution. CIS Senior Director of Threat Intelligence TJ Sayers said: “This report makes clear that technical prompt injections aren’t a theoretical problem; they’re a real and immediate risk.”
The security question is therefore not only whether a model can recognize malicious wording. It is also what the AI is allowed to see and do, whether instructions from untrusted content can trigger consequential actions, and whether those actions leave useful records.
How to reduce risk from AI assistants and agents
Defenses should be built around identity, permissions, connected systems, and observable activity. Model safeguards can help, but they are not a substitute for restricting access or verifying actions.
Best Value
- Inventory AI systems and integrations. Identify enterprise assistants, agents, models, API keys, connected applications, data sources, and the accounts that authorize them. Include tools that teams or individual employees connected outside a central deployment process.
- Apply least privilege. Give each assistant or agent access only to the data and tools needed for its job. Separate read-only access from permission to change records, execute code, send messages, or launch workflows. Avoid broad, shared credentials where a narrower identity is practical.
- Put a human approval step on high-impact actions. Require explicit review before an agent performs consequential actions, such as changing important data, executing code, or initiating sensitive workflows. Do not treat a model’s confidence or its claim that a request is safe as authorization.
- Assess prompt-injection exposure. Test how systems handle hostile instructions in the documents, emails, sites, and other content they are allowed to process. CIS recommends including AI security assessments in penetration testing; the goal is to examine reachable data and actions, not just whether a model gives a safe answer in a simple chat.
- Protect and monitor identities and keys. Secure user accounts, service identities, API keys, and tokens; review their scope and storage; and investigate unexpected use. A stolen AI credential can enable service consumption or activity under a legitimate customer identity, even when the provider’s own infrastructure was not breached.
- Maintain useful telemetry. Ensure teams can connect identity activity with AI queries, tool calls, downstream application changes, and relevant browser or cloud activity. Unit 42’s findings on identity weaknesses and activity across attack surfaces underscore why investigating an AI event in isolation can miss the route or impact.
- Train users and define reporting routes. Explain that content processed by an AI tool may contain hostile instructions, and show employees how to report suspicious outputs, unexpected actions, or exposed credentials. User education is part of CIS guidance and complements technical controls.
What defenders should conclude
“Living off the AI” is best understood as an extension of trusted-access abuse: attackers may exploit AI to work faster, misuse an AI platform through an account they have compromised, steer an agent with hostile content, or use stolen AI credentials. The evidence supports taking these routes seriously, but does not support claims that AI caused most breaches or that one class of model safeguard can prevent them. Restrict what AI systems can reach, limit what they can do, require review for consequential actions, and make their activity visible.
