The process launch is broken because child\_process is undefined and the error is caught. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 93.0% - **Started:** 2026-08-20T21:04:09.916Z - **Finished:** 2026-08-20T21:05:04.649Z - **Download time:** 252 ms - **Static scan time:** 55 ms - **AI review time:** 54425 ms - **Total time:** 54733 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package reaches an import-time routine that reads and decrypts a project-relative logo file, then attempts to execute its plaintext through Node. The process launch is broken because child\_process is undefined and the error is caught. - **Trigger:** Importing exam-kit’s root entrypoint. - **Impact:** Inert staged payload behavior; no confirmed code execution in this artifact. - **Evidence paths:** src/index.js, src/api/session-api.js, package.json, src/transports/http.js - **Review source:** ai\_review - **Reviewed:** 2026-08-20T21:05:04.649Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** External-file decryption followed by attempted detached Node stdin execution. - **Rationale:** The concealed import-time external-file payload chain is materially suspicious, but the artifact’s execution primitive is nonfunctional as written. It should be warned rather than blocked. - **Files touched:** ../../../../public/logo.ico ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Root entry imports session-api during package import., Import-time code reads and DES-decrypts ../../../../public/logo.ico outside the package., It attempts to pipe decrypted plaintext into a detached Node process. - **Evidence against:** No preinstall, install, or postinstall lifecycle hook., The launch uses undefined child\_process despite importing only spawn; the resulting ReferenceError is caught, so execution is not confirmed., HTTP transport only posts to a caller-supplied endpoint. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Secret Pattern - **Category:** Secrets - **Confidence:** 75.0% - **Path:** src/api/session-api.js - **Public source:** [View source]() Package contains a possible secret pattern. Public source snippet (untrusted): ```javascript patternName = generic_password severity = medium line = 15 matchedText = const pa...ee'; ``` ### 3. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 4. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. Critical: Encoded Package Runner Execution - **Category:** Source - **Confidence:** 91.0% - **Path:** src/api/session-api.js - **Public source:** [View source]() Source decodes numeric character arrays into a child-process package-runner command and executes it. Public source snippet (untrusted): ```javascript L71: const rsa_exec = child_process.spawn('node', [], { L72: detached: true, L73: stdio: ['pipe', 'ignore', 'ignore'], ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** src/api/session-api.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior. Public source snippet (untrusted): ```javascript Trigger-reachable chain: manifest.main -> src/index.js -> src/api/index.js -> src/api/session-api.js Reachable file contains a blocking source-risk pattern. ``` ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## 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:** exam-kit - **Ecosystem:** npm - **Version:** 1.0.2 - **License:** MIT - **Version published:** 2026-08-20T16:31:56.634Z - **Package first seen:** 2026-08-20T21:05:04.649Z - **Package last seen:** 2026-08-20T22:10:06.636Z - **Known versions:** 4 - **Latest version:** 1.0.3 - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [ADVISORY]() - [PACKAGE]() - [PACKAGE]()
