aws-blognpm
Advisory published Updated
aws-blog is a confirmed malicious npm package (MAL-2026-15498) that executes malicious code on install (malicious versions 45.0.0, 45.0.1, 45.0.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in aws-blog (npm)
What this malware does
package.json declares a dependency whose key equals the package's own name (aws-blog) with a value of https://repo.securityctrl.com/aws-blog instead of a registry version range. On npm install, npm fetches whatever tarball bytes that URL currently returns and installs it, running any lifecycle scripts inside it. There is no version pin and no integrity hash, so the executed code is whatever the operator of repo.securityctrl.com serves at install time and can change silently between installs. The shipped source is an inert stub, so the manifest line is the entire published surface of the package. The dependency-confusion shape (self-named key, implausibly high 45.0.0 version to win resolution against an internal aws-blog, host unrelated to any AWS or npm infrastructure) further indicates targeting of installers who expect an internal package by this name.
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.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for aws-blog (3 malicious versions).
If you installed it — respond
Remove aws-blog 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 aws-blog 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 aws-blog-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.
