Re: Encrypt All - See Nothing
This has been on the minds of InfoSec hackers for a few years now. Using packet lengths and times in behavioral analysis and fingerprinting the application with TLS metadata are two methods that can be successful as long as the software doing the traffic monitoring is sophisticated.

In "Identifying Encrypted Malware traffic with Contextual Flow Data" (Blake Anderson, David McGrew) for instance, the authors wrote a custom libcap-based tool to capture data features from live traffic. Some characteristics they identified as being attached to malware within the encrypted traffic included larger numbers of characters in the domain, much larger numbers of IPs per DNS request, and of course each we not found on Alexa top-N lists.

Not all features were as easily defined between traffic containing malware and not, but this paper and others since are a good sign all is not lost through the shift to HTTPs.

Dog vs. Dodge
Should "Dodge" be used instead of "Dog" in the title of this article?

Encrypt All - See Nothing
Encryption is both a blessing and a curse for security, and the increase use of encrypted channels by malware highlights the downsides. As more and more of the internal and external IP traffic shifts to encrypted 443, the ability of traditional IDS/IPS and other related tools to see the traffic and spot malicious payloads is erased. With the drive by Google and others to drive all websites to HTTPS by marking HTTP websites as unsafe, before long encrypted traffic will be the expected norm. 

With this evolution, the ability to look at where traffic is going, rather than what it contains will increasiningly be used as a means to spot malicous traffic. Whether it is connections to known C&C systems or outbound connections to foreign countries at 2am when the company has no business connections there, security tools that leverage DNS as part of behavioural traffic analysis are the next wave in the fight against those who want to infiltrate and compromize corporate systems.
