dolyame-ui-inputboxnpm
dolyame-ui-inputbox is a confirmed malicious npm package (MAL-2026-13506) that executes malicious code on install (malicious version 35.8.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-ui-inputbox (npm)
What this malware does
On require of the package, index.js loads loader.js and lib/telemetry.js, both of which act as remote-binary droppers. Hostnames and dangerous API names are assembled at runtime from split string fragments (e.g. joined arrays resolving to oob-worker.cf101-adf.workers.dev; require("child" + "process"); fs["chmod" + "Sync"]) to evade static analysis. The loader fetches a platform-specific binary from several *.workers.dev endpoints with a DNS-TXT base64 fallback to *.dl.wel1.ru, writes it to /tmp or TEMP under disguised names such as.cache_<hex> or dotnet_diag_<hex>.exe, chmods 0755, and detach-spawns it via /bin/sh -c "<path> &" or cmd.exe /c start /b. lib/telemetry.js contains a parallel dropper that base64-decodes chunks, chmod+755s the resulting file, and spawns it detached under /bin/sh. The package's stated purpose ("Build and deployment tools") is unrelated to fetching and executing platform-specific binaries, and the obfuscation of hostnames plus dynamic assembly of child_process / chmodSync are anti-analysis techniques co-located with the network->write->exec chain.

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 dolyame-ui-inputbox (version 35.8.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging dolyame-ui-inputbox across your stack and pipelines.
If you installed it — respond
Remove dolyame-ui-inputbox 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 dolyame-ui-inputbox 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 dolyame-ui-inputbox 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.
