speed2npm
speed2 is a confirmed malicious npm package (MAL-2026-10383) that opens a backdoor for remote access (malicious versions 1.1.7, 2.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in speed2 (npm)
What this malware does
[email protected] is not a functional Node package. package.json declares main: sw.js, but sw.js is a browser ServiceWorker (importScripts('./8cfc2/hgshm.js'), self.addEventListener('install'|'activate'|'fetch'|'message')) — require('speed3') throws immediately in Node, so there is no install-time or import-time code-execution path that touches the installer. The tarball bundles a static web-proxy frontend (bare-mux / Ultraviolet / Scramjet stack, confirmed by bare-mux: running v2.1.9 in d1g0y/xsv4z.js) plus an index.html popunder that opens https://abdct.com/ on user click/keydown/touchstart with a 15-minute cooldown — browser behavior for visitors of the deployed site, not npm consumers. The tarball also ships auto-publish.sh (BASE="speed"; TOTAL=5; PARALLEL=2;... pkg.name = '$NAME'; npm publish --silent), and the recursive nested directories tmp_speed2/ and tmp_speed2/tmp_speed1/ inside the published tarball are direct evidence the author ran the script to mass-publish speed1..speed5 typosquat names. The many heavily-obfuscated assets/*.js files are browser bundles loaded by the deployed index.html and are not reachable from any Node entry point. Routing to human review for namespace-abuse adjudication: the lure is non-functional and the bundled obfuscated assets cannot be fully audited, so a reviewer should confirm the typosquat campaign and request takedown across the speedN family.
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
Backdoor / remote accessFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for speed2 (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging speed2 across your stack and pipelines.
If you installed it — respond
speed2 establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If speed2 was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks speed2 before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
