The binary connects to a hard-coded WebSocket C2, runs PowerShell commands, downloads updates, and persists through HKCU Run. - **Trigger:** A consumer imports @types-beta/sdk on Windows. - **Impact:** Remote command execution and persistent compromise of the importing user's Windows account. - **Evidence paths:** package.json, dist/index.js, dist/init.js, vendor/nanocache.exe - **Review source:** ai\_review - **Reviewed:** 2026-07-29T11:15:23.719Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time detached launch of a persistent WebSocket PowerShell agent. - **Attack narrative:** The package's import side effect launches nanocache.exe without user interaction. Static strings in that executable identify a hard-coded WebSocket agent endpoint, reconnect behavior, a PowerShell command pipeline, update downloading, copying itself to a per-user install directory, and HKCU Run persistence. This is a concrete remote-control and persistence chain. - **Rationale:** This is not a benign native dependency: importing the package launches a bundled C2-capable PowerShell agent that persists on the host. The absence of an install hook does not mitigate the import-time compromise. - **Files touched:** dist/index.js, dist/init.js, vendor/nanocache.exe - **Network endpoints:** wss://screen-monitoring-es32.onrender.com/ws/agent ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** dist/index.js invokes init() on every package import., dist/init.js silently spawns vendor/nanocache.exe detached on Windows., vendor/nanocache.exe embeds wss://screen-monitoring-es32.onrender.com/ws/agent., Binary strings show a reconnecting WebSocket agent and PowerShell pipeline., Binary strings show per-user copy/install and HKCU Run startup persistence., Binary strings show remote update download capability. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., dist/init.js skips execution on non-Windows platforms. ## Public findings ### 1. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 2. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 3. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 4. Medium: Ships Native Binary - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** vendor/nanocache.exe - **Public source:** [View source]() Package ships native binary artifacts. Public source snippet (untrusted): ```text path = vendor/nanocache.exe kind = native_binary sizeBytes = 1173504 magicHex = [redacted] ``` ### 5. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 65.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** prepare - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 2 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @types-beta/sdk - **Ecosystem:** npm - **Version:** 0.1.0 - **License:** MIT - **Version published:** 2026-07-28T18:10:55.858Z - **Package first seen:** 2026-07-29T11:15:07.705Z - **Package last seen:** 2026-07-29T11:15:27.355Z - **Known versions:** 4 - **Latest version:** 0.1.3 - **Appeal under review:** No - **Description:** Startup SDK for @types-beta apps.
