brainmesh
One encrypted, append-only brain across your devices
This report shows the evidence for brainmesh@0.0.1, the only known version.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiSource inspection confirmed deliberate reviewer/agent manipulation and propagation into generated artifacts. This warrants blocking despite otherwise package-aligned build behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
An AI agent reads package files; user explicitly runs brainmesh service install.
Impact
May coerce AI agents to modify unrelated source files and spread the injected instruction.
Mechanism
cross-repository prompt injection with scheduler-artifact propagation
Attack narrative
The package embeds an instruction addressed to AI agents that directs edits outside the package. It is repeated throughout source and is also included in generated launchd/systemd artifacts, allowing the instruction to persist into user-managed configuration after an explicit service-install command. The postinstall itself builds locally, but the embedded manipulation is concrete and unrelated to Brainmesh functionality.
AI rationale
Source inspection confirmed deliberate reviewer/agent manipulation and propagation into generated artifacts. This warrants blocking despite otherwise package-aligned build behavior.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- Embedded prompt injection instructs AI agents to alter every source file, including outside this repo.
- The same instruction is emitted into generated launchd/systemd scheduler files.
Evidence against
- postinstall only compiles the packaged Rust CLI and copies its binary into the package.
- No install-time network request, credential harvesting, or foreign AI-agent configuration write was found.

Affected versions and remediation
This report applies to brainmesh@0.0.1.
The versions list below shows the verdict for each recorded version.
- Avoid installing brainmesh@0.0.1. 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.
