thalamus@1.5.21
Mobile and Web client for Claude Code
AI Security Review
scanned 1mo ago · by lpm-firewall-aiInspected lifecycle and runtime behavior is consistent with the package's remote-session functionality, with no concrete malicious chain identified. Native archive inspection establishes its structure and executable header, not a complete binary audit.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Installation extracts bundled tools; explicit CLI use activates remote sessions and daemon commands.
Impact
Observed writes support package state and session operations; no malicious credential export or foreign agent configuration mutation was established.
Mechanism
Runtime commands use authenticated sockets and encrypted RPC parameters. Claude OAuth usage requests send the token to Anthropic's fixed endpoint.
AI rationale
Inspected lifecycle and runtime behavior is consistent with the package's remote-session functionality, with no concrete malicious chain identified. Native archive inspection establishes its structure and executable header, not a complete binary audit.

Decision evidence
public snapshotAI called this Clean at 87.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook extracts bundled platform tools into tools/unpacked; it has no network or agent configuration operation.
- Both flagged API bundles resolve Claude project-history paths and read session files rather than modifying agent configuration.
- The MCP launcher starts the package's bridge with forwarded command arguments.
- Daemon installation is selected by an explicit CLI subcommand.
- Both library entrypoints expose API clients and configuration from the inspected bundles.
- The difftastic archive contains a single difft executable with an ARM64 ELF header; extraction does not execute it.
