search-reservationnpm
search-reservation is a confirmed malicious npm package (MAL-2026-15521) that executes malicious code on install (malicious version 55.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in search-reservation (npm)
What this malware does
package.json declares a dependency whose key equals the package's own name (search-reservation) and whose value is the bare URL https://repo.securityctrl.com/search-reservation instead of a registry version range. On npm install, npm resolves this URL, downloads whatever tarball it returns, and installs it — unpinned, integrity-unchecked, and running any lifecycle scripts inside the fetched artifact. Whoever controls repo.securityctrl.com controls code executed on the installer's machine. The shipped index.js is an inert stub, so the manifest URL is the entire delivery mechanism. The self-named dependency shape also matches dependency-confusion targeting of an internal package named search-reservation.

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 search-reservation (version 55.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging search-reservation across your stack and pipelines.
If you installed it — respond
Remove search-reservation 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 search-reservation 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 search-reservation 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.
