Lol, yeah.
The Slashdot article that led me to the original was slanted to say “legacy IT” equipment was the cause and had the distinct subtext that had they been using cloud for everything, they would have been fine.
Nope, this is 100% failure to provision and secure equipment correctly. And cloud doesn’t mean anything for security, especially given how many sensitive files have been left in wide-open, publicly accessible S3 buckets.
