Wow. At some point our talk hit HackerNews and then SlashDot after swirling around the Twitters for a few days. The attention is quite astounding given the relative lack of technical sexiness to this; explanations for the interest are welcome!
We wanted to highlight a few points that didn't make the slides but were mentioned in the talk:
- Bit.ly and GoWalla repaired the flaws extremely quickly, prior to the talk.
- PBS didn't get back to us.
- GlobWorld is in beta and isn't publicly available yet.
The potential risk assigned to exposed memcacheds hasn't as yet been publicly demonstrated so it's unsurprising that you'll find memcacheds around. I imagine this issue will flare and be hunted into extinction, at least on the public interwebs.
Lastly, the major interest seems to be on mining data from exposed caches. An equally disturbing issue is overwriting entries in the cache and this shouldn't be underestimated.
