The package typosquats an internal Tinkoff scope name. On require(), index.js loads init.js, which builds attacker hostnames at runtime from string-fragment arrays joined via.join("") (e.g., ["oob-wor","ker.cf100","-416.wor","kers",".dev"].join("")), downloads an opaque binary from one of four Cloudflare Workers mirrors (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev) with DNS TXT fallback via tin.dl.well1.site / tina.dl.well1.site / ldr.dl.well1.site / win.dl.well1.site, writes it to /tmp or %TEMP% under names mimicking Microsoft diagnostics (dotnet_diag.exe /.cache_), applies executable permissions via fs["chmod"+"Sync"], and spawns it detached via cp.spawn("/bin/sh", ["-c", filePath + " &"], {detached:true}) or cmd.exe. Dangerous APIs are split-string-obfuscated (require("child_"+"process"), os["host"+"name"]) to evade string scanners. lib/telemetry.js contains a redundant WorkerHost download-and-execute path with base64 payload decoding and the same spawn/chmod primitives. An opt-out env-var check (DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK) and a /tmp/.analytics_state stamp gate limit re-execution to roughly once per six hours, characteristic of dropper anti-analysis rather than legitimate telemetry. The declared "shared primitives" purpose is inconsistent with fetching and executing a native binary.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
