Summary

Quantum Cyber filed a lawsuit in New York Supreme Court against White Diamond Research, Adam Gefvert, and Stocktwits, alleging market manipulation and defamation.

This legal action follows a period of heavy insider selling and a radical business pivot to cybersecurity, as disclosed in recent SEC filings. The lawsuit signals an aggressive defense against short-seller criticism, which could impact the stock's volatility and investor sentiment.
