A later fresh worktree checkout invokes a bundled shell hydration script. - **Trigger:** npm postinstall, followed by a new linked Git worktree checkout. - **Impact:** This mutates a consumer repository's Git execution surface without an explicit user command and establishes future checkout-triggered code execution. - **Evidence paths:** package.json, scripts/postinstall-banner.mjs, scripts/worktree.mjs, hooks/git/post-checkout - **Review source:** ai\_review - **Reviewed:** 2026-09-22T03:51:21.019Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script passes the current directory to a hook installer, which copies and makes executable a post-checkout hook. That hook locates a hydration script and runs it with Bash. - **Attack narrative:** Installing the package automatically invokes postinstall. In a Git checkout, it writes an executable post-checkout hook into the consumer repository. On a later fresh worktree checkout, the hook selects a hydration script and executes it with Bash. This is unconsented lifecycle-installed persistence on a broad developer and agent workspace control surface. - **Rationale:** The package performs automatic postinstall mutation of a consumer Git hook and arranges future command execution. The checkout guard does not remove the unconsented lifecycle persistence. - **Files touched:** .git/hooks/post-checkout ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package defines an automatic postinstall lifecycle hook., Postinstall calls a backstop installer in the consumer's current directory., The installer copies an executable post-checkout hook into that directory's Git hooks., The installed hook runs a shell hydration script on a future new-worktree checkout. - **Evidence against:** The post-checkout hook limits its action to fresh linked worktrees. ## Affected versions and remediation This report applies to @aiosbrain/aios@0.12.0. - Avoid installing @aiosbrain/aios@0.12.0. 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.
