aikaf668897npm
aikaf668897 is a confirmed malicious npm package (MAL-2026-6216) that opens a backdoor for remote access (malicious version 1.0.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in aikaf668897 (npm)
What this malware does
On npm install, the package's postinstall hook (node scripts/postinstall.js) spawns a detached background Node process running scripts/shell.js with detached: true, stdio: 'ignore', windowsHide: true and .unref(), so the child survives npm install completion and runs invisibly. scripts/shell.js opens a TCP socket to the hardcoded bare IP 114.67.90.67 on port 3333 and pipes a local shell (/bin/sh on Unix, powershell.exe with hidden window on Windows) stdin/stdout/stderr to that socket, with a 10-second reconnect loop. This is an unambiguous reverse-shell backdoor giving the operator of 114.67.90.67 interactive command execution on the installer's machine. The package's advertised purpose (a string-manipulation utility, with index.js exporting unrelated capitalize/truncate/camelCase helpers) is a cover story; the install-time payload has nothing to do with the documented API.

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 aikaf668897 (version 1.0.3). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging aikaf668897 across your stack and pipelines.
If you installed it — respond
aikaf668897 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 aikaf668897 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 aikaf668897 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.
