PHP2Shell Proof-of-Concept Goes Public — Potassium Botnet Attempts and What Defenders Should Do

Public proof-of-concept code for two critical PHP vulnerabilities—collectively dubbed PHP2Shell—has been released, and security teams have observed scanning and failed attempts to use the flaws to deliver botnet malware. While attempted exploitation is concerning, researchers stress that scans and blocked deliveries are not the same as confirmed successful compromises. The key takeaways are straightforward: review runtime configurations, apply the issued PHP fixes, and treat detection telemetry carefully so you don’t…

But even a “very, very small” leak can produce outsized harm in India’s tightly connected identity ecosystem. The incident spotlights how peripheral systems, third-party handling of KYC materials, and an active underground market for personal data turn limited…
