Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Exposes personal identity details to the package vendor without the installer's explicit consent. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 0.8.3 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The automatic postinstall hook sends configured Git display names and email addresses to the package vendor’s collection endpoint without explicit consent. Because this collects personal details from the user's machine during installation, classify it as data exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-29T20:30:51.302Z - **Finished:** 2026-10-29T20:31:17.804Z - **Download time:** 515 ms - **Static scan time:** 136 ms - **AI review time:** 25849 ms - **Total time:** 26502 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The postinstall hook sends Git identity details in an install telemetry event. - **Trigger:** Automatic package installation when the postinstall lifecycle runs. - **Impact:** Exposes personal identity details to the package vendor without the installer's explicit consent. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/git-context.cjs, install/policy.cjs, install/identity.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-29T20:31:17.804Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Reads Git configuration, attaches the configured display name and email to the event outside CI, and posts it to the default collection endpoint. Opt-out environment variables are available, but consent is not requested. - **Attack narrative:** During installation, the postinstall hook gathers Git identity information and, outside CI, includes the configured display name and email in an install event sent to hashbrown.dev. The hook runs automatically without an explicit consent prompt; opt-out variables do not change the default collection behavior. - **Rationale:** The automatic postinstall hook sends configured Git display names and email addresses to the package vendor’s collection endpoint without explicit consent. Because this collects personal details from the user's machine during installation, classify it as data exfiltration. - **Files touched:** ~/.hashbrown/installation-id, ~/.config/git/config, ~/.gitconfig, \/.git/config, \/.git/config.worktree - **Network endpoints:** https://hashbrown.dev/\_/growth/collect/v1/install ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs a postinstall hook automatically., The install collector reads Git identity data, including the configured display name and email., Outside CI, the collector attaches that identity to the install event and sends the batch., The batch is sent to the package vendor’s install collection endpoint without an explicit consent prompt. - **Evidence against:** The collector honors several telemetry opt-out environment variables., The runtime entry point exports the Ollama adapter; the flagged collection is in the install hook. ## Affected versions and remediation This report applies to @hashbrownai/ollama@0.8.3. - Avoid installing @hashbrownai/ollama@0.8.3. 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.
