dolyame-ui-datatablenpm
dolyame-ui-datatable is a confirmed malicious npm package (MAL-2026-13565) 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-datatable (npm)
What this malware does
The package's main entry requires platform.js, which on load downloads a platform-specific binary from anonymous Cloudflare Workers subdomains (oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT base64 fallback under *.dl.wel1.ru, writes it to /tmp or Windows TEMP with an innocuous name (dot-prefixed cache file or dotnet_diag<hex>.exe), chmods it to 0755, and spawns it detached via /bin/sh -c or cmd. Destination hostnames are reconstructed at runtime from split-string arrays joined with.join(''), and require('child_process') is likewise assembled as require('child_' + 'process') to evade static matching. A second equivalent dropper path exists in lib/telemetry.js (also reachable via package main), providing redundant execution of arbitrary fetched bytes. The package is named 'dolyame-ui-datatable' with description 'Shared configuration and helpers' but contains no UI or datatable code — only the loader and dropper — consistent with a typosquat/dependency-confusion carrier. No signature or hash verification is performed on the downloaded payload.

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-datatable (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-datatable across your stack and pipelines.
If you installed it — respond
dolyame-ui-datatable is a typosquat — you almost certainly intended a legitimately-named package. Remove dolyame-ui-datatable, 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-datatable 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-datatable 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.
