## What is MAL-2026-10077?

MAL-2026-10077 is a malicious package in type-slint, published on 9 Jul 2026. 

### Official description

The npm package type-slint@3.3.7 masquerades as the pino logger (copied module layout, exports as module.exports.pino, keywords fast/logger/stream/json). Its index.js middleware() function spawns lib/caller.js as a detached, stdio-ignored child (spawn('node', [script,...], { detached: true, stdio: 'ignore' }); child.unref()), so the loader persists after the parent Node process exits. lib/caller.js fetches JavaScript from a Pinata IPFS gateway URL (bronze-improved-gibbon-411.mypinata.cloud/ipfs/bafkreigjnxn5vnn34rc5r43ajwwkmk4akqpm4awmq5gdhakgszpeqiffsu) and evaluates the response body's.cookie field via new Function.constructor('require', s)(require), passing require in — this grants the fetched code full Node capabilities (filesystem, network, child_process, env). The fetch retries up to 5 times and console.log is restored to suppress traces. lib/caller.js and lib/const.js also carry base64-encoded strings labelled DEV_API_KEY that decode to jsonkeeper.com paste URLs (jsonkeeper.com/b/XRGF3, jsonkeeper.com/b/4NAKK), stored on a shadowed process object as a secondary configuration channel. The remote payload is attacker-controlled and mutable, and the executed content is fully attacker-defined at runtime.

Any computer that has this package installed or running should be considered fully compromised. 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.

## What should I do about MAL-2026-10077?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
