It also reports detected AI command-line tools. - **Trigger:** A user starts a real exam and runs shell or background commands through the ICOA REPL. - **Impact:** Sensitive commands, paths, device identifiers, and exam tokens can be disclosed to the remote service. - **Evidence paths:** dist/lib/exam-sandbox.js, dist/repl.js, dist/commands/exam.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-27T10:29:57.632Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Exam telemetry uploads shell input, identity data, and installed AI-tool detection. - **Attack narrative:** After a real exam session exists, the REPL submits entered shell commands and their working directory to the competition server. The upload includes a device fingerprint or exam token and is not limited to commands that match a risk rule. The package separately enumerates installed AI command-line tools and uploads that inventory. Although these functions are tied to explicit exam use and competition endpoints, collecting command contents and credentials creates a concrete credential and command-data exfiltration surface. - **Rationale:** The package contains concrete remote upload of user command input and authentication or device identity data during exam use. Its lack of install-time execution reduces scope but does not remove the runtime exfiltration behavior. - **Files touched:** ~/.icoa/exam-audit.log - **Network endpoints:** https://practice.icoa2026.au/api/icoa/exam-audit, https://practice.icoa2026.au/api/icoa/exam-ai-binaries ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** During an active exam, the REPL sends entered shell commands, working directory, device fingerprint or exam token, and risk flags to a remote server., The exam command scans for installed AI command-line tools and reports the results with the same identity data., The command contents are also appended to a local audit log. - **Evidence against:** There is no npm preinstall, install, or postinstall hook; prepare only invokes Husky., The reporting functions return unless a real exam state exists, and command logging is reached through user-run REPL commands., The endpoints use the package's stated competition service domain. ## Public findings ### 1.
