Verify File Hashes for Malware
Check MD5, SHA1, or SHA256 file hashes against threat intelligence databases to determine if a file is known malware before executing it.
Quick answer: Use the Security Scanner tool through ToolRouter to verify file hashes for malware directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolWhen a suspicious file arrives — an attachment, a downloaded installer, an executable from a vendor — you need to know whether it matches any known malware samples before anyone runs it. Uploading files to unknown scanning services is a security risk in itself. Checking the hash avoids that problem: the file stays local, and the hash alone is checked against threat databases.
Security Scanner's `check_hash` skill queries MD5, SHA1, and SHA256 hashes against threat intelligence feeds, returning match verdicts, malware family names, and detection counts across scanning engines. You know within seconds whether a file is clean, suspicious, or a confirmed threat.
IT security teams, incident responders, and system administrators use this to vet files before deployment, verify downloads from third-party vendors, and triage attachments flagged by email filters.

Use Claude with Security Scanner to check file hashes and get a plain-language verdict with context. Claude explains what a malware family name means, how many engines detected it, and whether partial matches or clean scores warrant further investigation — not just the raw numbers.
How to verify file hashes for malware
Once connected (see setup above), use the Security Scanner tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:
- Generate the SHA256, SHA1, or MD5 hash of the file you want to check (using certutil, sha256sum, or your OS hash tool).
- Provide the hash to Claude and ask it to check via `security-scanner` with `check_hash`.
- Ask Claude to explain the verdict — malware family, detection count, and confidence level.
- Ask whether the result is decisive or whether the file needs further analysis before it can be trusted.
Example prompt
Try this with the Security Scanner tool
Use security-scanner to check this SHA256 hash: 3395856ce81f2b7382dee72602f798b642f14140d912dc31f34e09bb5938b2f5. Tell me the verdict, any malware family name, how many engines detected it, and whether I should treat this file as safe or escalate for further analysis.
Tips
- Always hash the file locally — never upload the file itself to an external service for initial triage.
- Ask Claude what confidence level the detection count represents — 1 engine detecting versus 40 is materially different.
- Check hashes of software received from vendors before running in production, not just files from unknown sources.
Frequently Asked Questions
How do I verify file hashes for malware with an AI assistant?
Check MD5, SHA1, or SHA256 file hashes against threat intelligence databases to determine if a file is known malware before executing it. Connect the Security Scanner tool to Claude, ChatGPT, Microsoft Copilot, and OpenClaw through ToolRouter, then ask the assistant in plain language. For example: Generate the SHA256, SHA1, or MD5 hash of the file you want to check (using certutil, sha256sum, or your OS hash tool). Provide the hash to Claude and ask it to check via `security-scanner` with `check_hash`.
Which AI assistants can verify file hashes for malware?
Claude, ChatGPT, Microsoft Copilot, and OpenClaw can all verify file hashes for malware using the Security Scanner tool through ToolRouter, with no API keys or coding required.
