The overlay captures foreground content, uses AI services to solve it, and actively evades proctoring or capture controls. - **Trigger:** Running the bmcat command activates the detached launcher and Electron application; screen edges and global hotkeys activate capture and submission. - **Impact:** Enables concealed exam or assessment cheating, persistent user-space execution, and exposure or misuse of AI session credentials. - **Evidence paths:** package.json, bin/kalamasha-tool.js, main.js, bin/stealth\_capture.ps1, bin/uia\_extract.py, bin/chrome\_cookies.ps1, profile-picker.html, config.json - **Review source:** ai\_review - **Reviewed:** 2026-08-28T21:42:18.134Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Stealth proctoring evasion, foreground capture, and AI-session automation. - **Attack narrative:** A user who runs the package starts a detached launcher that copies Electron under a plausible Windows process name and respawns it. The application makes a hidden overlay resistant to screenshots and proctor interference, captures the active window through UI automation or GDI, and sends captured questions to logged-in AI services. It also ships code to decrypt browser cookies and code to inject AI session tokens. This is a concealed cheating and credential-misuse tool, not the DOM diagnostic utility claimed in its metadata. - **Rationale:** Source inspection confirms a concrete stealth, persistence, capture, and AI-assisted cheating workflow. Its credential-handling code and bundled credential material compound the risk, so publication should be blocked. - **Files touched:** bin/kalamasha-tool.js, main.js, bin/stealth\_capture.ps1, bin/uia\_extract.py, bin/uia\_extract.exe, bin/chrome\_cookies.ps1, config.json, %LOCALAPPDATA%\\Microsoft\\Windows\\Diagnostics\\boot.log, %LOCALAPPDATA%\\Microsoft\\Windows\\Diagnostics\\.kill\_watchdog - **Network endpoints:** https://chatgpt.com/?model=auto, https://chat.openai.com, https://claude.ai, https://gemini.google.com/app, https://ipc.shadxino.internal/login\_post ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The command launcher creates a detached watchdog, disguises an Electron copy as SearchApp.exe, and respawns it after termination., The main process hides its overlay from capture and repeatedly counters Testpad/proctor windows., Runtime hotkeys and screen-edge actions capture foreground text or images, then submit them to AI services., The package includes a browser-cookie decryption utility for OpenAI-related domains and code that injects session tokens into AI-service cookies., The bundled configuration contains credential material; it should not have been published. - **Evidence against:** The postinstall hook only attempts to require Electron and does not launch the application., The inspected source does not show the cookie extractor being invoked by the application., No separate attacker-controlled exfiltration host was identified; the observed external destinations are AI services selected by the package. ## Public findings ### 1.
