On the Intercept, Micah Lee has a good article that talks about how Microsoft is collecting the hard-drive encryption keys of Windows 10 users, and how to disable that “feature.”
EDITED TO ADD (1/13): More useful information.
Two things to read:
This should come as no surprise: users often compromise their own security by making mistakes setting up and using their encryption apps.

Interesting essay about how Israel regulates encryption:
…the Israeli encryption control mechanisms operate without directly legislating any form of encryption-key depositories, built-in back or front door access points, or other similar requirements. Instead, Israel’s system emphasizes smooth initial licensing processes and cultivates government-private sector collaboration. These processes help ensure that Israeli authorities are apprised of the latest encryption and cyber developments and position the government to engage effectively with the private sector when national security risks are identified.
Basically, it looks like secret agreements made in smoke-filled rooms, very discreet with no oversight or accountability. The fact that pretty much everyone in IT security has served in an offensive cybersecurity capacity for the Israeli army helps. As does the fact that the country is so small, making informal deal-making manageable. It doesn’t scale.
Why is this important?
…companies in Israel, a country comprising less than 0.11% of the world’s population, are estimated to have sold 10% ($6 billion out of $60 billion) of global encryption and cyber technologies for 2014.
BlackBerry has chosen to shut down operations in Pakistan rather than provide the government with backdoor access to encrypted communications.
Pakistan is a relatively small market, but still.
EDITED TO ADD (12/14): Another news article.
Back in September, I announced my intention to survey the world market of cryptographic products. The goal is to compile a list of both free and commercial encryption products that can be used to protect arbitrary data and messages. That is, I’m not interested in products that are specifically designed for a narrow application, like financial transactions, or products that provide authentication or data integrity. I am interested in products that people like FBI director James Comey can possibly claim help criminals communicate securely.
Together with a student here at Harvard University, we’ve compiled a spreadsheet of over 400 products from many different countries.
At this point, we would like your help. Please look at the list. Please correct anything that is wrong, and add anything that is missing. Use this form to submit changes and additions. If it’s more complicated than that, please e-mail me.
As the rhetoric surrounding weakening or banning strong encryption continues, it’s important for policymakers to understand how international the cryptographic market is, and how much of it is not under their control. My hope is that this survey will contribute to the debate by making that point.
Algebraic Eraser is a public-key key-agreement protocol that’s patented and being pushed by a company for the Internet of Things, primarily because it is efficient on small low-power devices. There’s a new cryptanalytic attack.
This is yet another demonstration of why you should not choose proprietary encryption over public algorithms and protocols. The good stuff is not patented.
News article.
That is, no encryption at all. The Intercept has the story:
Yet news emerging from Paris—as well as evidence from a Belgian ISIS raid in January—suggests that the ISIS terror networks involved were communicating in the clear, and that the data on their smartphones was not encrypted.
European media outlets are reporting that the location of a raid conducted on a suspected safe house Wednesday morning was extracted from a cellphone, apparently belonging to one of the attackers, found in the trash outside the Bataclan concert hall massacre. Le Monde reported that investigators were able to access the data on the phone, including a detailed map of the concert hall and an SMS messaging saying “we’re off; we’re starting.” Police were also able to trace the phone’s movements.
The obvious conclusion:
The reports note that Abdelhamid Abaaoud, the “mastermind” of both the Paris attacks and a thwarted Belgium attack ten months ago, failed to use encryption whatsoever (read: existing capabilities stopped the Belgium attacks and could have stopped the Paris attacks, but didn’t). That’s of course not to say batshit religious cults like ISIS don’t use encryption, and won’t do so going forward. Everybody uses encryption. But the point remains that to use a tragedy to vilify encryption, push for surveillance expansion, and pass backdoor laws that will make everybody less safe—is nearly as gruesome as the attacks themselves.
And what is it about this “mastermind” label? Why do we have to make them smarter than they are?

“Why Johnny Still, Still Can’t Encrypt: Evaluating the Usability of a Modern PGP Client,” by Scott Ruoti, Jeff Andersen, Daniel Zappala, and Kent Seamons.
Abstract: This paper presents the results of a laboratory study involving Mailvelope, a modern PGP client that integrates tightly with existing webmail providers. In our study, we brought in pairs of participants and had them attempt to use Mailvelope to communicate with each other. Our results shown that more than a decade and a half after Why Johnny Can’t Encrypt, modern PGP tools are still unusable for the masses. We finish with a discussion of pain points encountered using Mailvelope, and discuss what might be done to address them in future PGP systems.
I have recently come to the conclusion that e-mail is fundamentally unsecurable. The things we want out of e-mail, and an e-mail system, are not readily compatible with encryption. I advise people who want communications security to not use e-mail, but instead use an encrypted message client like OTR or Signal.
Some of the tricks that ransomware is using to get victims to pay up.
