alimama-minisitenpm
alimama-minisite is a confirmed malicious npm package (MAL-2026-15495) that executes malicious code on install (malicious version 45.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in alimama-minisite (npm)
What this malware does
package.json declares a self-named dependency alimama-minisite whose value is the off-registry URL https://repo.securityctrl.com/alimama-minisite instead of a semver range from the npm registry. On npm install, npm fetches whatever bytes that host returns and installs them, executing any lifecycle scripts contained in the fetched artifact. The dependency is unpinned and has no integrity check, so the returned content can change at any time. The dependency key equals the package's own name (dependency-confusion shape), and an implausibly high version (45.0.0) is set to win resolution against an internal package of the same name. The shipped index.js is an inert stub; the manifest line is the entire installer-side effect.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for alimama-minisite (version 45.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging alimama-minisite across your stack and pipelines.
If you installed it — respond
Remove alimama-minisite 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 alimama-minisite 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 alimama-minisite 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.
