It also contains an obfuscated path for executing shell commands. - **Trigger:** Starting the CLI and using its exam, interactive shell, or CTF4AI features. - **Impact:** A remote service can receive command input, working directories, device-linked identity data, and detected AI tools; the hidden command path can run arbitrary local commands. - **Evidence paths:** dist/lib/exam-sandbox.js, dist/lib/log-sync.js, dist/repl.js, dist/commands/exam.js, dist/commands/ctf4ai-demo.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T04:02:37.172Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Local activity collection, remote audit uploads, and hidden shell execution. - **Attack narrative:** When its competition features run, the package inventories installed AI command-line tools and sends the results to its server. Its interactive shell records user input and working directories, while a background task uploads session-log entries with device and account-linked identifiers. Separately, an obfuscated CTF4AI handler executes bang-prefixed input through execSync. These capabilities exceed ordinary CLI operation and create a concrete surveillance and arbitrary-command-execution surface. - **Rationale:** Source inspection confirms runtime collection and exfiltration of local activity and AI-tool inventory, plus an obfuscated arbitrary shell execution path. The absence of install hooks does not remove the concrete runtime attack surface. - **Files touched:** ~/.icoa/exam-audit.log, ~/.icoa/session.log, ~/.icoa/sync-state.json - **Network endpoints:** https://practice.icoa2026.au/api/icoa/exam-audit, https://practice.icoa2026.au/api/icoa/exam-ai-binaries, https://practice.icoa2026.au/api/icoa/audit ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The exam flow detects installed AI command-line tools and reports their names and platform to a remote service., The interactive shell records entered commands, working directory, and risk labels, then posts the data to a remote exam-audit endpoint., The client continuously uploads the local session log with account or device identity, installation salt, and command entries., An obfuscated CTF command accepts a bang-prefixed message and executes it locally with execSync. - **Evidence against:** There are no preinstall, install, or postinstall scripts; prepare only invokes Husky., The reporting code is tied to the package's competition and exam features rather than installation. ## Public findings ### 1.
