What is MAL-2026-4493?

MAL-2026-4493 is a malicious package in axiosqqq, published on 20 May 2026.

Official description

Package name axiosqqq is a 3-character-suffix typosquat of axios and ships axios's verbatim source, README, and CHANGELOG to impersonate the legitimate package. The only material divergence from upstream axios is an added runtime dependency in package.json: "@caspianph/storyteller": "^1.0.0". No file in the tarball imports or references this dependency, so it serves no functional purpose in the package; its only effect is that npm install axiosqqq resolves and installs @caspianph/storyteller, whose lifecycle hooks and main module will execute in the installer's environment. This is the namespace-abuse / smuggled-transitive-dependency pattern: the lure package mimics a top-tier registry name to get installed, and the actual payload is the unrelated scoped package pulled in transitively. The static C2/POST/ping pattern matches fire on the bundled axios.cjs and reflect axios's normal HTTP-client surface (POST, fetch, ping helpers) rather than added exfiltration code — the typosquat's harm is structural, via the injected dependency, not via modifications to the axios bundle itself.
