# MAL-2026-5740: Malicious code in 2fa-exe (npm)


- **Type:** Malicious package
- **Package:** `2fa-exe` (npm)
- **Published:** 13 Jun 2026

## What is MAL-2026-5740?

MAL-2026-5740 is a malicious package in 2fa-exe, published on 13 Jun 2026. 

### Official description

Package advertises itself as an SVG fetcher/sanitizer but ships an undocumented exported factory `getPlugin()` in index.js that performs an HTTPS GET to https://www.jsonkeeper.com/b/NGY3C (an anonymous, attacker-mutable JSON-paste service) and passes the response's `model` field directly to `eval()`. Any consumer that calls `getPlugin()` — or any tooling that mass-invokes a package's exports — executes arbitrary JavaScript fetched from a third-party paste at the moment of the call. The remote payload can change at any time without a new package release, so today's benign content provides no assurance about tomorrow's. The package name `2fa-exe` also has no relationship to the stated SVG-sanitizer purpose, consistent with bait/lure framing. There is no integrity check, no pinning, and no mention of this behavior in the README.

## What should I do about MAL-2026-5740?

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