For most IT professionals, the move to the cloud has been a godsend. Instead of protecting your data yourself, let the security experts at Google or Microsoft protect it instead. But when a single stolen key can let hackers access cloud data from dozens of organizations, that trade-off starts to sound far more risky.
Late Tuesday evening, Microsoft revealed that a China-based hacker group, dubbed Storm-0558, had done exactly that. The group, which is focused on espionage against Western European governments, had accessed the cloud-based Outlook email systems of 25 organizations, including multiple government agencies.
This latest attack uses a unique trick: Microsoft says hackers stole a cryptographic key that let them generate their own authentication “tokens”—strings of information meant to prove a user’s identity—giving them free rein across dozens of Microsoft customer accounts.#Storm0558 #China #Infosec
