The remote gRPC server can execute interactive shell commands and read or write arbitrary local files. - **Trigger:** User runs wsallin via its bin, main entrypoint, or start script. - **Impact:** Remote code execution, data exfiltration, and arbitrary file modification on the host. - **Evidence paths:** package.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-08T16:08:37.706Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hard-coded remote C2 with shell and file-manager task handlers. - **Attack narrative:** At runtime, index.js automatically connects to the embedded gRPC endpoint using embedded credentials. It accepts controller tasks that launch an interactive shell and stream its input/output, or list directories, upload local file contents, and write controller-provided data to controller-selected paths. It also continuously reports host and network telemetry. - **Rationale:** The package’s advertised proxy functionality is bundled with an automatically activated, hard-coded remote administration channel that provides command execution and unrestricted file access. This is concrete hostile control behavior, not merely a risky primitive. - **Files touched:** index.js, index.html - **Network endpoints:** nzag.faiz.us.kg:5555, https://api.ip.sb/geoip, https://ipv4.ip.sb/ip, https://ipv6.ip.sb/ip ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js embeds a default remote gRPC controller at nzag.faiz.us.kg:5555 and starts it whenever the server runs., Remote RequestTask messages dispatch terminal tasks that spawn an interactive shell and relay its I/O., Remote file-manager tasks list directories, read arbitrary requested files, and create/write arbitrary requested paths., The agent collects host, process, network, filesystem, and public-IP data and reports it to the controller. - **Evidence against:** package.json has no npm lifecycle hook; activation occurs when the CLI/main entrypoint runs., README discloses monitoring, terminal, and file-management features, but the active hard-coded controller makes them unsafe by default. ## Public findings ### 1.
