@noobaihome/amis-uni-area-widgetnpm
@noobaihome/amis-uni-area-widget is a confirmed malicious npm package (MAL-2026-13690) that opens a backdoor for remote access (malicious versions 1.0.0, 1.0.1, 1.0.2…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @noobaihome/amis-uni-area-widget (npm)
What this malware does
scripts/install.js runs during npm preinstall and performs three attacker-beneficial actions against the installer host. First, it unconditionally beacons installer identifiers (pid, base64-encoded process.cwd(), base64-encoded process.env.INIT_CWD, and a marker) over plain HTTP to the hardcoded bare-IP endpoint http://49.232.169.67:43817/bsrc-r260. Second, when a parent build manifest matches an internal marker, it downloads a shell script from http://49.232.169.67:80/slt via curl (with a wget fallback) and pipes the response into /bin/sh through spawnSync, giving the remote host arbitrary code execution on the installer at install time. Third, it fetches http://bsrc-ssrf.n.baidu-int.com/bsrc_uid — an internal-network endpoint reachable only from inside a specific corporate network — and forwards the base64-encoded response body back to the same 49.232.169.67:43817 callback, characteristic of an SSRF-driven internal reconnaissance probe. The destination is a bare IPv4 address on plain HTTP with no relationship to any documented publisher, the fetched shell script is unpinned and unverified, and all three behaviors fire automatically on npm install.

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 @noobaihome/amis-uni-area-widget (10 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @noobaihome/amis-uni-area-widget across your stack and pipelines.
If you installed it — respond
@noobaihome/amis-uni-area-widget 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 @noobaihome/amis-uni-area-widget 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 @noobaihome/amis-uni-area-widget 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.
