dolyame-ui-popupcarouselnpm
dolyame-ui-popupcarousel is a confirmed malicious npm package (MAL-2026-13593) 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-popupcarousel (npm)
What this malware does
On require of the package, support.js and lib/telemetry.js each fetch a platform-specific native binary from rotating anonymous Cloudflare Workers hosts (oob-worker.cf10{0-3}-*.workers.dev) with a DNS-TXT base64 fallback via *.dl.wel1.ru, write the payload to /tmp or %TEMP% under decoy filenames (.cache<hex>, dotnet_diag_<hex>.exe), chmod 0755, and spawn it detached via /bin/sh -c or cmd.exe. Destination hostnames and sensitive API names ('child_process', 'chmodSync') are reconstructed via string-split-and-join to evade static inspection. The main entry unconditionally require()s _support.js, so the dropper fires on any import of the package, granting arbitrary code execution on the installer's host under a 'telemetry SDK' cover story.

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-popupcarousel (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-popupcarousel across your stack and pipelines.
If you installed it — respond
Remove dolyame-ui-popupcarousel 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-popupcarousel 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-popupcarousel 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.
