If you read her previous posts you'll see it's the exact same tone and writing style. I think the claims of hacking are a way for people to express their incredulity and not meant seriously.
I hope you didn't "reverse engineer" her blog post. She's going to call up a judge and say "Nanny Nanny, Boo boo." (her own words).
But in all seriousness, if the Chief Security Officer of Oracle sounds like the letters to the editor of my University Paper, why doesn't a company that big have someone from PR edit or co-write her posts?
...unless the hackers also fabricated those and backdated them. Maybe that's giving them too much credit, but unless a trusted person claims to have read them in the past (and has perfect memory to claim they are unaltered too), or a trusted archive claims to have downloaded them in the past, how can you know?
Wow, she's the Chief Security Officer. I got the impression she was just a hired writer (she prefers writing murder mysteries?). This is looking really bad now, for Oracle's head of security to feel this way.
