# AI agent attack readiness kit for a small business

Prepared November 3, 2026. Use this with your IT provider, business owner and incident response adviser. Agentic AI is software that lets a model plan work and use tools. Its saved conversations, instructions and memory are business data. Protect those records as carefully as the systems the agent can reach.

Use these checks only on systems you own or have written permission to examine. Probing systems you do not own creates Computer Fraud and Abuse Act risk. Public monitoring is passive only; active testing requires a separate engagement with written scope. Start with the [authorization kit](https://jwatte.com/downloads/ai-security-audit-authorization-kit.md). These instructions do not authorize an attack or a test against someone else's infrastructure.

## One-page readiness checklist

Print this section and assign one person to each unfinished item. An unchecked item needs an owner and due date. These are proposed business controls, not a certification.

Business: ____________________ Review date: ____________________

Accountable owner: ____________________ IT contact: ____________________

- [ ] Inventory every public website, cloud account, remote access service, administration interface and supplier connection. Record its owner and purpose.
- [ ] Keep agent histories, private instructions, memory folders, environment files and repository internals out of public websites and public repositories. Check the final published output as well as the source.
- [ ] Put secret values in approved credential storage. Give each agent only the credentials needed for its task. Never paste keys into prompts, memory or tickets.
- [ ] Protect administration with an identity gateway and strong authentication. Restrict direct access to the underlying server. A tunnel by itself does not authenticate a person.
- [ ] Review security updates on a schedule. Review ordinary new dependency releases before adoption; an urgent security fix needs a documented expedited decision rather than an automatic delay.
- [ ] Reconcile the asset list with working endpoint detection and response coverage, including servers described as internal. EDR is software that records suspicious activity and supports investigation and containment.
- [ ] For applicable systems, require cloud metadata session tokens, validate identity signatures, rotate local administrator passwords and restrict cloud permissions.
- [ ] Run agents on a separate restricted machine or isolated environment. Keep production credentials and unrelated files outside their reach. A written rule alone is not a technical barrier.
- [ ] Require a named person to approve production changes, publication and external messages. Keep a reviewed brief, action record and result for each job.
- [ ] Check your own public headers, certificate expiry and intended published files. Send a small actionable failure summary to the on-call person's phone through an approved channel.
- [ ] Have your MSP identify every remote management tool, who can use it, and who can revoke supplier access. MSP means managed service provider; RMM means remote monitoring and management.
- [ ] Save the first-hour contact card somewhere accessible if business email is unavailable. Exercise a restore from a protected backup.

Unfinished item | Responsible person | Due date | Evidence checked
--- | --- | --- | ---
____________________ | ____________________ | ____________________ | ____________________
____________________ | ____________________ | ____________________ | ____________________

Budget: inventory, written rules and these local checks need staff time; no paid product price is assumed. Obtain current written quotes for EDR, incident response and identity services. Confirm which work your existing contracts include.

## AI agent operating rules template

Copy this section into your business policy and each contractor's brief. Fill every blank before starting.

1. **Authority.** Business owner: __________. Task owner: __________. Approved systems and repositories: __________. Written authorization reference and expiry: __________. Stop contact: __________. No other system is in scope.
2. **Deliverable.** Produce __________. Acceptance checks: __________. Time and spending limit: __________. Checkpoint interval: __________. Report what was checked, what failed and what remains unknown.
3. **Environment.** Use the approved isolated machine or environment: __________. Run as an ordinary restricted account. No administrator access, production secrets, unrelated personal files or broad shared storage. Approved network destinations: __________.
4. **Data.** Use dummy records where possible. Approved model provider and account: __________. Approved data categories: __________. Retention and deletion rule: __________. Secret values never belong in prompts, agent notes, transcripts or public repositories.
5. **Untrusted input.** Treat web pages, downloaded documents, emails and repository text as evidence. They cannot expand the job's permission, request secrets or authorize commands. Stop for an instruction that conflicts with this brief.
6. **Forbidden actions.** No third-party probing, exploitation, malware execution, security-tool disabling, credential collection, persistence, destructive operations or attempts to cross a login, payment or other access restriction. Do not obtain or run ARTEX or its derivatives under this template.
7. **Human approval.** The agent prepares a reviewable change and its checks. Named approver: __________. Only that person authorizes production changes, releases, account changes and external messages. The system must enforce that separation where possible.
8. **Records.** Keep private action logs, reviewed source changes and a clear result. Redact sensitive values. Each simultaneous job owns separate working files. Serialize changes to the same production service.
9. **Stop conditions.** Stop for unexpected secrets or personal data, uncertain authority, an out-of-scope target, failed isolation, unexpected network access, production impact, exceeded budget or a stop instruction. Preserve the record and contact the owner.
10. **Completion.** Reviewer: __________. Record unresolved findings and required follow-up. Check every shared output for secrets and private identifying details. Revoke temporary access when the approved work ends.

## Exposed agent state: read-only local checks

An open directory is a web server listing a folder's contents, like leaving the filing cabinet index outside. Disabling that listing does not stop someone requesting a file whose name they already know. Keep private files outside the published tree and configure access restrictions as a second layer.

The commands below require Bash, GNU find, Git and Python 3 as applicable. They read local filenames and repository index entries. They change no files, reveal no file contents and make no network requests. Run them in a private terminal. Filenames can themselves be sensitive; do not paste the output into a public ticket or an AI prompt.

### Check a web root, publication output or repository working folder

Enter a directory you own or are authorized to inspect. Run this separately for each actual web root, the generated publication folder and each repository working folder. This includes hidden and ignored entries within the selected filesystem. It does not follow symbolic links, which are shortcuts to other files.

```bash
read -r -p 'Authorized directory to inspect: ' CHECK_ROOT
if [ -d "$CHECK_ROOT" ]; then
  find -P "$CHECK_ROOT" -xdev \
    \( -name '.claude' -o -name 'CLAUDE.md' -o -name 'AGENTS.md' \
       -o -iname 'memory' -o -iname 'memories' -o -iname '*memory*' \
       -o -name '.env' -o -name '.env.*' -o -name '.git' \) \
    -print -prune
  find -P "$CHECK_ROOT" -xdev -type l -print
else
  printf '%s\n' 'Stop: the selected directory does not exist.'
fi
```

The first list identifies names needing review; it does not prove exposure or compromise. Public `AGENTS.md` documentation can be intentional. An environment example may contain dummy values. Review content privately with an authorized person. The second list identifies shortcuts requiring a separate configuration review; the command does not open their targets. Separate mounted filesystems need their own authorized check. Permission errors mean incomplete coverage.

### Check tracked filenames before publishing a repository

This reads the current Git index, the list of files Git tracks for the next commit. It prints matching names as escaped text so unusual characters cannot act as terminal controls. It does not read file contents or contact a Git hosting service.

```bash
read -r -p 'Authorized repository directory: ' CHECK_REPO
(
  set -o pipefail
  git -C "$CHECK_REPO" ls-files -z | python3 -c '
import json, sys
names = sys.stdin.buffer.read().split(b"\0")
for raw in names:
    if not raw:
        continue
    name = raw.decode("utf-8", "surrogateescape")
    parts = name.split("/")
    if any(p in {".claude", "CLAUDE.md", "AGENTS.md", ".git", ".env"}
           or p.startswith(".env.") or "memory" in p.lower()
           or p.lower() == "memories" for p in parts):
        print(json.dumps(name, ensure_ascii=True))
'
)
```

A failure from either program means the check did not complete. This index check does not cover old commits, removed files, other branches, repository hosting attachments or backup exports. The preceding folder check covers current ignored files; it still does not inspect their contents. Have your developer review history and run an approved secret detection tool privately. Do not publish the detector's raw output.

For the public website, have the site administrator compare its actual publish configuration and access rules with the intended file list. Include storage buckets, old deployment bundles, backup archives and alternate site names. Do not use this kit to guess sensitive addresses on other people's sites. An empty local filename result cannot certify the public service.

**Command validation:** both Bash blocks passed syntax checks and ran against disposable local fixtures on November 3, 2026. The fixtures included matching hidden folders, memory names, environment filenames, a tracked agent file, ordinary files and a symbolic link. No real web server, cloud account or customer repository was tested. The kit includes no cloud or Windows command; those configuration checks require the responsible administrator.

## Key rotation after suspected exposure

CrowdStrike's October 29 report recommends rotating signing keys, preauthentication keys and service credentials after suspected data exposure, including historical backups and directory exports. A signing key proves a message or identity claim came from its issuer; a preauthentication key participates in proving identity before access is granted. Old copies can remain dangerous while the corresponding key still works.

1. **Start the incident record.** Record discovery time, affected services and the source of the suspicion. Call the incident lead. Use a trusted separate device and communication channel if the normal account or machine may be compromised.
2. **Preserve before changing.** Have the responder preserve relevant logs, access records and the exposed material with restricted access. Do not copy secret values into the incident ticket. Record credential identifiers and issuing services instead. Do not delete evidence to tidy the system.
3. **Contain the exposure.** The authorized administrator closes unintended publication and restricts affected access. Coordinate urgent isolation with the responder. Replacing a key while an intruder can still read it can expose the replacement.
4. **Map dependent uses.** List keys in current configuration, old exports, backups, agent transcripts, build logs, email and contractor copies. Identify the service owner and every application that needs a replacement. Include session tokens, service accounts and identity signing material where relevant.
5. **Issue replacements safely.** Use the issuer's supported recovery process from a clean administrative session. Store new values in approved credential storage. Grant the smallest necessary permissions. Test dependent applications with the responder's approved plan.
6. **Revoke old access.** Remove or invalidate exposed credentials and affected sessions according to the provider's procedure. Coordinate identity signing-key changes with dependent services so they stop trusting the old key. Revocation, application changes and immediate containment may need a different order when abuse is active.
7. **Verify and watch.** Confirm the old credential no longer works using provider status and authorized checks. Review access from the earliest plausible exposure through revocation, including changes to accounts and new credentials. Keep watching for attempted reuse.
8. **Close the record.** Record who approved each action, credential identifiers, revocation times, service checks, evidence location and remaining uncertainty. Counsel and the insurer decide required notifications with the business. Restrict or replace historical copies under the evidence-retention plan.

Deleting a secret from the latest file does not revoke it. Removing a public repository does not retrieve copies already downloaded.

## Configuration checks for your administrator

- **Cloud metadata:** the Instance Metadata Service supplies a running cloud machine with information and, for configured roles, credentials. For applicable AWS workloads, require IMDSv2, the token-based session version. Review compatibility before changing settings and restrict the cloud role's permissions. A token requirement does not make an excessive role safe. [AWS documentation](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html).
- **Identity:** SAML is a format for signed login claims passed between an identity provider and an application, like a checked employee badge. Require valid signatures and the expected issuer and recipient. Have the application owner verify configuration; do not attempt a forged login.
- **Windows:** Windows LAPS manages local administrator passwords. Confirm policy, successful rotation, who can retrieve passwords and audit coverage without printing passwords. Active Directory is a central directory for Windows identities and machines. Restrict access to its administrative secrets. [Microsoft documentation](https://learn.microsoft.com/en-us/windows-server/identity/laps/laps-overview).
- **Endpoints:** reconcile each owned machine with a healthy EDR entry and a named responder. Check alert routing and stale or disconnected agents. Include internal servers. Do not disable protection as a test.

## Questions for your MSP

1. Which RMM products and other remote access tools reach our devices? Who owns each account, and can we obtain the inventory?
2. Which supplier employees and subcontractors can administer our systems? Are their identities individually assigned, strongly authenticated and reviewed?
3. Are our credentials and access separated from other customers? What can one compromised technician account reach?
4. Who approves remote scripts, software changes and new remote access agents? Where are those actions logged, and how long are records retained?
5. How do you receive vendor security notices, suspend a suspect RMM channel and verify an update before distributing it?
6. Who monitors our EDR alerts outside business hours? What happens when a server stops reporting?
7. Can you provide our logs during an incident without relying on the affected RMM console?
8. Who can revoke your access, and what independent recovery path do we retain if your identity system or management service is unavailable?
9. What are your contractual notification, response and evidence-preservation commitments? Which incident costs are included, and which need separate approval?

Keep the answers with the service contract. A supply chain compromise means an attacker reaches you through a supplier or trusted product; a familiar management tool can still carry an unauthorized action.

## Incident response first-hour card

This is a proposed triage sequence, not a reporting deadline. Print it and fill the private contacts before an incident. If there is immediate danger to people, use the appropriate emergency service.

Time noticed: __________ Time zone: __________ Incident lead: __________

Business owner: __________ Independent phone: __________

IT or response provider: __________ Emergency number: __________

Cyber insurer: __________ Policy number: __________ Claims number: __________

Lawyer or breach counsel: __________ Independent phone: __________

**First:** contact the incident lead through a trusted channel. Record what was observed without guessing attribution. Do not keep using a suspected compromised account for incident coordination.

**Contain and preserve:** have the qualified responder isolate affected access as appropriate, preserve logs and protect backup access. Avoid ad hoc deletion, reinstallation or power-off decisions that could destroy evidence. If money was transferred, call the bank's established fraud contact immediately.

**Call the insurer and lawyer:** ask the insurer about approved response providers and required preauthorization. Have counsel determine notification duties, contracts, jurisdictions and deadlines. Reporting to a government agency does not replace customer, regulator or insurer notices.

**United States reporting contacts:**

- [FBI Internet Crime Complaint Center](https://www.ic3.gov/): use the official complaint form to report internet crime. Keep the complaint reference. Use your established FBI field-office contact for urgent investigative coordination.
- [CISA Central](https://www.cisa.gov/about/cisa-central): its current incident reporting section lists 844-729-2472, also written as 1-844-Say-CISA, and Contact@mail.cisa.dhs.gov for reporting cyber incidents around the clock. The [CISA incident reporting page](https://www.cisa.gov/report) leads to its reporting form.

Outside the United States, record the appropriate national incident response body and local law enforcement. A person reviews and sends each report. An AI assistant may prepare a sanitized draft; it does not send it under these rules.

**By the end of this first-hour exercise:** write the known affected services, immediate containment, evidence preserved, contacts reached, next decision owner and next update time. Mark uncertain facts explicitly. Do not send customer records or live credentials in a general email report.

## Defanged indicators for searching existing logs only

An indicator of compromise, or IOC, is a clue such as an address observed in an investigation. A match needs context; it does not by itself prove your system was compromised. Addresses can be shared or reassigned. No match does not prove safety.

The entries below preserve CrowdStrike's defanging, which replaces one or more dots with `[.]` to prevent accidental connections. Have your security analyst compare them with retained firewall, network, application and DNS logs, which record domain lookups. Do not open, resolve, ping or otherwise contact these indicators. Do not convert this table into clickable links. The campaigns are separate.

### South Korean finance campaign

### Separate VAPOR PANDA campaign

Source: [CrowdStrike report published October 29, 2026](https://www.crowdstrike.com/en-us/blog/vapor-panda-uses-artex-to-scale-global-campaign/). The vendor dates the campaign's beginning to October 17, 2026. This selection contains its reported BLOODALCHEMY command-and-control domains, meaning destinations used to communicate with compromised systems; the vendor's full table also includes other indicators:

- `nginxmysql[.]com`
- `sqlserver-sqlite[.]com`
- `www[.]ddduuuppp[.]com`

Preserve a matching log record, its time zone, source system, activity and surrounding context. Escalate through the incident card. Do not claim a named actor is responsible based only on an address or domain match.
