Microsoft cloud cybersecurity attacks up 300% in last year, report says

Microsoft cloud user accounts saw a 300% increase in cyberattacks over the past year, according to volume 22 of the Microsoft Security Intelligence Report, released Thursday. The report, announced in a blog post, focused primarily on cloud and endpoint data.

Why such a big increase?

“A large majority of these compromises are the result of weak, guessable passwords and poor password management, followed by targeted phishing attacks and breaches of third-party services,” the report said.
