10-shardsight-webnpm
Advisory published Updated
10-shardsight-web is a confirmed malicious npm package (MAL-2026-14362) that executes malicious code on install (malicious versions 1.0.0, 1.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in 10-shardsight-web (npm)
What this malware does
index.js is a top-level async IIFE that fetches HTML from the hardcoded, unpinned URL https://bitbucket.org/p2p-alt-public/p2p-emis/raw/main/GameWebSight, replaces document.head and document.body with the fetched markup, and re-creates every <script> tag so the remote JavaScript executes in the consumer's page. The source is a mutable main branch on a personal-looking Bitbucket workspace unrelated to any declared publisher, with no integrity check, so whoever controls that repository can push arbitrary JavaScript that runs in the page context of any application that loads this package.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for 10-shardsight-web (2 malicious versions).
If you installed it — respond
Remove 10-shardsight-web 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 10-shardsight-web 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 10-shardsight-web-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.
