dolyame-ui-clickoutsidehocnpm
dolyame-ui-clickoutsidehoc is a confirmed malicious npm package (MAL-2026-13558) that typosquats a legitimate package to trick installs (malicious version 35.8.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-ui-clickoutsidehoc (npm)
What this malware does
On require() of this package, index.js loads shim.js which assembles hostnames from split string fragments to hide them (e.g. ["oob-work","er.cf100-416.workers",".dev"].join("") and ['sd','k.dl.wel1.r','u'].join("")), fetches a platform-specific executable from Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS TXT covert-channel fallback under sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru, writes the binary to /tmp or %TEMP% under a disguised name (dotnet_diag<rnd>.exe or.cache_<rnd>), chmods it 0755, and spawns it detached via /bin/sh -c or cmd. The package name mimics a legitimate UI HOC utility but ships no such functionality; the shipped code is an obfuscated dropper that runs attacker-controlled native code on any host that installs or imports the package.

Detection & response playbook
TyposquatFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for dolyame-ui-clickoutsidehoc (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-clickoutsidehoc across your stack and pipelines.
If you installed it — respond
dolyame-ui-clickoutsidehoc is a typosquat — you almost certainly intended a legitimately-named package. Remove dolyame-ui-clickoutsidehoc, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If dolyame-ui-clickoutsidehoc 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-clickoutsidehoc 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.
