Friday Squid Blogging: Nano-Sized SQUIDS
SQUID news:
Physicists have developed a small, compact superconducting quantum interference device (SQUID) that can detect magnetic fields. The team l focused on the instrument’s core, which contains two parallel layers of graphene.
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

I think its no suprise to most of you but I think it’s worth point out this article of Dr. Neal Krawetz on the achiles heel of TOR:

Traffic analysis is quite an obvious attack on low latency networks such as TOR. The TOR developers actually acknowledge this, stating something like “if your threat actor is NSA you better run”, my words not theirs.
What I find interesting in the article is the claim that there are “private companies/group of individuals” with a god eyes view of the Internet. With the snowden revelations we know NSA/GCHQ [1] as such capabilities by tapping on major fiber optic backbones/choke points but I thought this wasn’t available for the average joe.
