Share Market Crash: Four companies backed by ace investor Vijay Kedia plunged up to 20% after AI startup Anthropic launched Claude Code Security, a tool that detects and fixes vulnerabilities in open-source software. TAC Infosec, TechD Cybersecurity, Sattrix Information Security, and Exato Technologies saw sharp declines. The move highlights concerns that AI-driven automation could disrupt traditional cybersecurity and legacy system modernization, including COBOL-based financial and government systems, affecting investors and the tech industry globally.
