AI changes the speed, scale and plausibility of familiar cyberattacks; it does not make every attack autonomous or guarantee more successful breaches. The most useful response is to strengthen core controls—identity, verification, asset and data visibility, patching, monitoring, backups and incident response—while securing the AI services and integrations your organization uses.

What AI changes about cyber risk

AI can help attackers produce convincing messages, tailor lures to individuals, research targets, find weaknesses, adapt malware and coordinate steps in an intrusion. These capabilities can reduce effort and accelerate parts of an attack, but they are not proof that any particular attack is automated, widespread or more likely to succeed.

NIST’s Cybersecurity Framework Profile for Artificial Intelligence (IR 8596) was an initial preliminary draft dated December 2025. It describes potential AI-enabled patterns including realistic spear-phishing, manipulated audio and video, convincing malicious websites, malware designed to evade signature-based detection, and agents coordinating reconnaissance, credential theft, lateral movement and collection. Treat those as threat examples in draft guidance, not measured prevalence statistics.

NIST’s Generative Artificial Intelligence Profile (AI 600-1) describes two related concerns: generative AI may lower barriers to offensive capability, and AI systems add their own attack surface. That distinction matters: an organization can be attacked with AI, or an attacker can target the organization’s AI systems, data and connected tools.

Build a reliable picture of exposure

Start with an inventory that covers both conventional technology and AI. It should be useful enough to tell you what is exposed, what data it handles, who can access it and what actions it can perform.

  • Technology and identity: internet-facing services, endpoints, software, privileged accounts, service accounts and third-party dependencies.
  • Data: sensitive information, where it is stored and processed, and which people, applications and vendors can access it.
  • AI use: approved and unapproved AI services, model APIs, plugins, retrieval sources, integrations and the business processes that depend on them.
  • Permissions and dependencies: which connected systems an AI tool can read or change, and which vendors or services it relies on.

Revisit the inventory as teams adopt new AI tools. NIST’s AI risk-management guidance calls for understanding data dependencies and reevaluating data inventories as AI use expands. A tool that only summarizes public information has a different exposure from one that can retrieve confidential records or initiate transactions.

Make identity and sensitive requests harder to spoof

Raise the bar for account access

Require multifactor authentication (MFA), prioritize phishing-resistant MFA for privileged and other high-risk accounts, and apply least privilege. CISA’s surfaced guidance for its election-focused generative-AI risk document recommends strong protocols including phishing-resistant MFA; that document is not a general organizational deployment standard. NIST’s draft profile also points to integrated defenses for email and authentication.

A FIDO2 hardware security key is one possible way to implement phishing-resistant authentication. Before choosing one, verify compatibility with your identity provider, account types, devices, enrollment process and recovery procedures; not every key works with every provider or deployment. No particular brand or model is established here.

Verify high-impact requests out of band

Do not let a convincing email, chat, phone call or video meeting serve as its own proof of identity. Establish a separate verification path—such as calling a known number from an internal directory or using an approved workflow—for payment-detail changes, credential requests, sensitive data transfers and privileged actions. Require a second approver where the consequence warrants it.

Update staff exercises to include realistic text, voice and video impersonation. The goal is not to ask employees to spot every synthetic artifact; it is to make independent verification the normal process for consequential requests.

Keep email, endpoints and vulnerabilities under control

Maintain layered email protections, endpoint detection, centralized logging and a regular patch process. Keep asset visibility current so internet-exposed systems and high-risk vulnerabilities can be prioritized. AI-assisted reconnaissance and obfuscated malware are reasons to avoid relying solely on static signatures or manual discovery—not evidence that existing security products fail universally.

Secure AI services, data and integrations

AI security requires controls around the full system, not just the model. NIST’s AI 600-1 discusses prompt injection—including indirect prompt injection embedded in material a system retrieves—and data poisoning. NIST AI 100-2 E2025 provides a taxonomy for adversarial machine-learning threats, including evasion, poisoning, privacy and misuse. Its four categories are a way to organize attack types, not a measure of incident frequency.

Set boundaries before deployment

  • Maintain an approval and inventory process for AI services, APIs, plugins and integrations.
  • Define what information staff may send to external AI services; limit sensitive data exposure and use approved services for protected work.
  • Constrain permissions to the minimum needed. Separate read access from write or execution privileges where possible.
  • Require human approval for high-impact, external or irreversible actions, rather than allowing an AI component to take them unaided.
  • Track model, data, retrieval-source and dependency changes, and maintain a practical way to disable an integration.

Test the ways an AI workflow can fail

Evaluate the workflow as deployed, including connected tools and data sources. Test direct and indirect prompt injection, manipulated retrieval content, data leakage, model or dependency integrity, and service availability. Check whether a hostile instruction can cause the system to expose data or exceed its intended permissions. Protect confidentiality, integrity and availability across inputs, processing, training, deployment environments, model components and connected tools.

These controls reduce risk; they do not guarantee that an AI system is immune to attack. NIST’s adversarial-machine-learning report describes mitigation approaches but also notes that available defenses lack robust assurances of fully mitigating the risks.

Prepare to detect, contain and recover

Incident response should be part of normal risk management, not a plan kept apart from operations. NIST finalized SP 800-61 Revision 3 on April 3, 2025; it supersedes Revision 2 and aligns incident-response recommendations with the six functions of the Cybersecurity Framework 2.0.

  1. Assign decision owners. Identify who can revoke credentials, isolate systems, disable AI integrations, approve recovery and coordinate internal or external communications.
  2. Practice containment. Rehearse account lockout and credential revocation, endpoint or service isolation, and suspension of an affected integration. Know how to preserve evidence while limiting damage.
  3. Protect evidence and visibility. Retain logs needed to reconstruct activity across identity, email, endpoints, cloud services and AI-connected systems.
  4. Test restoration. Use protected backups and verify that critical data and services can be restored. A backup that has not been restored in a test is not a proven recovery path.
  5. Exercise relevant scenarios. Include AI-generated phishing, manipulated executive audio or video, compromised AI integrations and suspicious agent activity in tabletop or operational exercises.

Use defensive AI with evaluation and oversight

AI-assisted tools may help analysts with detection, response and recovery, but their presence is not proof of complete coverage. NIST’s preliminary IR 8596 profile calls for continuous evaluation of defensive capabilities and whether they are mature enough for an organization’s needs.

Before relying on a tool, evaluate it against representative data and measure both false positives and missed detections. Review what data it can access, how that data is retained, how it fits existing controls and whether permissions can be constrained. Keep an accountable human in the loop for consequential actions, and establish how to override or disable the tool.

A practical order of work

  1. First: inventory exposed assets, identities, sensitive data and AI tools; identify high-impact accounts and systems.
  2. Next: strengthen MFA and independent verification for high-risk access and business requests.
  3. Then: close visibility and maintenance gaps in email, endpoints, logging and vulnerability remediation.
  4. Before expanding AI use: define data and permission boundaries, test injection and leakage scenarios, and establish a disable path.
  5. Finally: rehearse containment and recovery, test backups, and evaluate any AI-based defensive tooling on actual organizational needs.
