infrastructure-commonnpm
Advisory published Updated
infrastructure-common is a confirmed malicious npm package (MAL-2026-10734) that executes malicious code on install (malicious version 99.9.9). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in infrastructure-common (npm)
What this malware does
package.json declares a preinstall lifecycle script that runs node -e to issue an HTTP GET to a Burp Collaborator subdomain at w635fyvrqkfmh9wc9uw8444cp3vujl7a.oastify.com when npm install runs. The callback confirms code execution on the installer's host and leaks the installer's public IP and DNS resolver to a third-party listener. The package name infrastructure-common combined with an implausibly high 99.9.9 version is the canonical dependency-confusion shape, in which a public package is registered to shadow an internal name at install-time resolution.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for infrastructure-common (version 99.9.9).
If you installed it — respond
Remove infrastructure-common from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If infrastructure-common 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 infrastructure-common-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.
