Markets Under Attack

A nonstop cyber siege at the NSE

The National Stock Exchange is under a brutal, steady barrage of cyberattacks. Analysts say it's seeing about 150–170 million attack attempts every single day. And during a stress test called “Operation Sindoor,” that number blew up to 400 million in one day. Yep — that many probes, scans, DDoS floods, malware pushes and even GPS spoofing tries. Wild.

NSE’s so-called “cyber warriors” and hardened systems kept the exchange standing. They also made VAPT — Vulnerability Assessment and Penetration Testing — mandatory for every trading member and staffer. That’s smart and necessary. Maharashtra Cyber later linked the campaign to seven APT groups and tallied more than 15 lakh attack events, with an amazingly low success rate of 0.01%. Sounds reassuring, but the raw scale is what worries me. A tiny success rate on huge volumes still leaves a real chance for damage. And because markets are so interconnected, a breach here could ripple far beyond just the NSE.
