WannaCry after one year

In the news, Boeing (an aircraft maker) has been "targeted by a WannaCry virus attack". Phrased this way, it's implausible. There are no new attacks targeting people with WannaCry. There is either no WannaCry, or it's simply a continuation of the attack from a year ago.

Some notes on memcached DDoS

AskRob: Does Tor let government peek at vuln info?

On Twitter, somebody asked this question:

The question is about a blog post that claims Tor privately tips off the government about vulnerabilities, using as proof a "vulnerability" from October 2007 that wasn't made public until 2011.

The tl;dr is that it's bunk. There was no vulnerability, it was a feature request. The details were already public. There was no spy agency involved, but the agency that does Voice of America, and which tries to protect activists under foreign repressive regimes.
