Wondering if the "unblock" has anything to do with the conspicuous lack of content on the homepages of all the catalyst sites.
Dunno if it's related to what happened to Catalyst, but one may also want to be aware of:
http://arstechnica.com/security/2016/02/mysterious-spike-in-wordpress-hacks-silently-delivers-ransomware-to-visitors/Which has gotten a few sites I know running WP tossed on the blacklist
(while I laugh at the people who use WP by choice -- I know, stop flagellating the deceased equine) all had this rather nasty bugger...
The disturbing part is it's attack vector remains something of a mystery, though iframe based video embeds (of all things) seem to be related. What makes that REALLY disturbing is IFRAME's are supposed to block cross site exploits -- but again there's a reason we were told 18 years ago to stop using them. Shame 99% of web developers stuck their fingers in their ears and just didn't want to hear that they couldn't use their precious IFRAME tags anymore.
Though again, Wordpress' "one ring" of security and leaving the keys to the kingdom danging in plain sight behind the main gate... well, exploits like that are hardly a surprise. There's esoteric attacks you can't predict, and then there's having ZERO fallback plan should someone get inside.
GOOD news is, if you keep all your plugins up to date (flash, acrobat, silverlight) or just block them, this nasty can't infect you.
It's still just outright bizarre how it's breaking out of the container into the hosting website, and spreading to sites that don't actually have those video embeds from one WP install to another if they so much as talk to each-other in other ways. (like sharing posts via RSS through certain extensions)
I'm waiting for an exploit like this to reach "neverNoSanity" proportions -- where all the people who neutered their upgrade paths on phpBB by adding mods/extensions that weren't being updated ended up 4 to 6 months behind on patches, and the end result took down two thirds the Internet... the CBT I was running at the time included NOT because we were using it, but because someone else on the same server was.
WP just has that vibe of something like that looming over the horizon... Of course with their "zero damages zero accountability" open source policy, it's not like they REALLY have to care so long as they can keep duping people into using it.
...and why I still say no legitimate business has any business using it for a website. YMMV. It's not bad enough it's accessibility trash and insecure code, but the lack of legal recourse thanks to it being open source? There's a reason it took so long for open source to gain traction in business, and we have yet to have a "major" enough failure for that detail to be contested -- but I've seen this pattern before, and it's coming.
