## Summary

Timo Zhang, a third-year Sun Yat-sen University student, released BLA, an open-source MCP service and CLI tool that counters AI reverse engineering. BLA plants realistic fake credentials and decoy Source Maps, and it pushes files past analyzer quota limits, which the author says raises token consumption 300 to 2800 times. On 14 GitHub repository samples, the author estimates total token use rose about 639.5 times and cost about 304.4 times.

## Why it matters

The source explains how BLA poisons files and exhausts analyzer quotas to inflate AI reverse-engineering token costs, a concrete method and cost estimate.
