Commvault’s Azure Breach: No Customer Data Compromised, But Watch Out for Webshells!
Commvault assures customers that a nation-state cyber attack on its Azure environment didn’t compromise backup data. While the breach was serious enough to involve the FBI, Commvault’s safeguards held firm. The company, listed on NASDAQ and serving over 100,000 organizations, remains a fortress in the data protection realm.

Hot Take:
Looks like Commvault just pulled a slick magician’s trick—”Now you see me, now you don’t”—with that sneaky nation-state threat actor. Despite the attempted breach, customer backup data remained untouched, all thanks to Commvault’s cybersecurity savvy. No rabbits were pulled out of hats, but they did manage to keep their data safe from disappearing! Hats off to them for keeping the ‘vault’ in Commvault secure. It seems the only thing that went missing was the threat actor’s success rate!
Key Points:
