Has the ESA website been hijacked?! (no joke) (UPDATE: yes, but they've fixed it)

I just tried to visit the Ecological Society of America website, and Google gave me this:

What the hell?! The diagnostic page says that over the past 90 days, a bunch of pages from esa.org resulted in malicious software being downloaded without user consent, including a bunch of exploits and trojans. I'm guessing this means the ESA website was hijacked sometime within the last few months?

UPDATE: Via the ESA Twitter feed, I see that the site was indeed hijacked within the last 24 hours. It's been fixed, but it'll take about 24 h for Google to recognize the fix.
