Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Running the package bin disguises an Electron app as Windows Search, keeps a watchdog that relaunches it, and hides an overlay from capture and the taskbar. A bundled script decrypts browser cookies for OpenAI hosts, and a PowerShell helper copies the foreground window. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-26T05:36:45.134Z - **Finished:** 2026-09-26T05:38:18.845Z - **Download time:** 764 ms - **Static scan time:** 264 ms - **AI review time:** 92682 ms - **Total time:** 93711 ms The recorded confidence comes from the underlying analysis.

A bundled script decrypts browser cookies for OpenAI hosts, and a PowerShell helper copies the foreground window. - **Trigger:** User or npm start/test execution of bin/kalamasha-tool.js, which spawns main.js. Cookie extraction runs when bin/chrome\_cookies.ps1 is executed. - **Impact:** A concealed persistent process can evade proctoring and screen sharing, capture on-screen content, and recover browser session cookies for ChatGPT and OpenAI hosts. - **Evidence paths:** bin/kalamasha-tool.js, main.js, bin/stealth\_capture.ps1, bin/chrome\_cookies.ps1, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-26T05:38:18.845Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher copies electron.exe to SearchApp.exe and respawns it. main.js uses user32 display affinity and tool-window styles, a global input hook, and stealth\_capture.ps1. chrome\_cookies.ps1 copies browser cookie databases and decrypts them with DPAPI. - **Attack narrative:** The published bin is a disguised exam-cheat implant, not a DOM utility. On start it copies Electron to SearchApp.exe, detaches, and restarts if killed. The Electron app hides an overlay from screenshots and the taskbar, hooks input, and grabs the foreground window through PowerShell. A bundled script decrypts Chrome, Edge, and Brave cookies for OpenAI and ChatGPT and prints them as JSON. Install does not auto-run this, but the shipped runtime is built to stay hidden and take session material and screen content. - **Rationale:** The launcher, overlay, screen grabber, and browser-cookie decryptor are concrete stealth and credential-theft behavior under a false package description. Install does not auto-start them, but the shipped bin and scripts are an active implant once the documented start command runs. - **Files touched:** %LOCALAPPDATA%\\Microsoft\\Windows\\Diagnostics, %LOCALAPPDATA%\\Google\\Chrome\\User Data, %LOCALAPPDATA%\\Microsoft\\Edge\\User Data, %LOCALAPPDATA%\\BraveSoftware\\Brave-Browser\\User Data, SearchApp.exe - **Network endpoints:** https://chatgpt.com, https://claude.ai, https://gemini.google.com ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The bin entry copies Electron to SearchApp.exe, detaches from the terminal, and respawns the process if it is killed., main.js builds a hidden always-on-top overlay titled SearchApp and sets Windows display affinity so the window is excluded from screen capture., On a hotkey, main.js runs bin/stealth\_capture.ps1 with PowerShell execution-policy bypass to copy the foreground window via GDI., bin/chrome\_cookies.ps1 reads Chrome, Edge, and Brave cookie databases, decrypts the key with DPAPI, and prints session cookies as JSON., package.json start and test scripts, and the exiouss bin, launch bin/kalamasha-tool.js. The postinstall script only prints a message. - **Evidence against:** The postinstall hook does not start the watchdog or the cookie script., No JavaScript reference calls chrome\_cookies.ps1, so cookie dumping is not on the automatic start path. ## Affected versions and remediation This report applies to exiouss@5.0.1. - Avoid installing exiouss@5.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
