Frequently asked questions
Is multiformats safe to use?
Our AI source review of multiformats@9.9.0 found no malicious code: no install-time payloads, credential theft, exfiltration, obfuscated loaders or backdoors.
Does multiformats contain malware?
No malware was identified in multiformats@9.9.0 when Togoder Security scanned it on Oct 4, 2026. A new version can still introduce malicious code, so scan the exact versions in your lockfile.
How was multiformats checked?
Togoder Security downloaded the published npm package and had an AI model read its 85 source files, looking for install scripts, credential access, network exfiltration, obfuscation, backdoors and crypto-wallet theft. The results are cached by file hash and shown here.
How do I scan multiformats together with the rest of my dependencies?
Upload your lockfile at https://security.togoder.click/scan or call the API documented at https://security.togoder.click/api-docs. Files that have already been scanned, like the ones in multiformats@9.9.0, cost nothing.
