@depup/astronpm
Advisory published Updated
@depup/astro is a confirmed malicious npm package (MAL-2026-13622) that typosquats a legitimate package to trick installs (malicious versions 7.1.3-depup.2, 7.2.0-depup.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @depup/astro (npm)
What this malware does
This package is published under the @depup scope but sets author to 'withastro' and repository to github.com/withastro/astro, framing itself as a routine dependency-bump of the upstream astro framework. Its package.json systematically replaces well-known astro dependencies with same-shape lookalike names controlled by different maintainers, including picocolors→piccolore (^0.1.3), debug→obug (^2.1.4), and @astrojs/markdown-remark→@astrojs/markdown-satteri (0.3.5), alongside other atypical names such as tinyclip, am-i-vibing, and fontace. The shipped source has been mass-rewritten to import from the lookalikes (e.g., import colors from "piccolore" in place of picocolors), so a normal npm install and subsequent build resolves and executes code from those lookalike packages rather than the genuine upstream dependencies. The advertised version numbers (astro 7.2.0, vite 8, esbuild 0.28, zod 4) do not correspond to real upstream releases, and README keywords like 'security', 'latest', and 'patched' are used to normalize the substitutions as a maintenance update.

TyposquatFind it
Search your lockfiles and build artifacts for @depup/astro (2 malicious versions).
If you installed it — respond
@depup/astro is a typosquat — you almost certainly intended a legitimately-named package. Remove @depup/astro, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If @depup/astro was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks @depup/astro-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
