Internet censors have a new strategy in their bid to block applications and websites: pressuring the large cloud providers that host them. These providers have concerns that are much broader than the targets of censorship efforts, so they have the choice of either standing up to the censors or capitulating in order to maximize their business. Today's internet largely reflects the dominance of a handful of companies behind the cloud services, search engines and mobile platforms that underpin the technology landscape. This new centralization radically tips the balance between those who want to censor parts of the internet and those trying to evade censorship.
The security threats will keep getting worse.
On May 25, the FBI asked us all to reboot our routers. The story behind this request is one of sophisticated malware and unsophisticated home-network security, and it's a harbinger of the sorts of pervasive threats — from nation-states, criminals and hackers — that we should expect in coming years.
VPNFilter is a sophisticated piece of malware that infects mostly older home and small-office routers made by Linksys, MikroTik, Netgear, QNAP and TP-Link. (For a list of specific models, click here.) It's an impressive piece of work. It can eavesdrop on traffic passing through the router — specifically, log-in credentials and SCADA traffic, which is a networking protocol that controls power plants, chemical plants and industrial systems — attack other targets on the Internet and destructively "kill" its infected device.
When Marc Zuckerberg testified before both the House and the Senate last month, it became immediately obvious that few US lawmakers had any appetite to regulate the pervasive surveillance taking place on the internet.
Right now, the only way we can force these companies to take our privacy more seriously is through the market. But the market is broken. First, none of us do business directly with these data brokers.
Last week, researchers disclosed vulnerabilities in a large number of encrypted email clients: specifically, those that use OpenPGP and S/MIME, including Thunderbird and AppleMail. These are serious vulnerabilities: An attacker who can alter mail sent to a vulnerable client can trick that client into sending a copy of the plaintext to a web server controlled by that attacker. The story of these vulnerabilities and the tale of how they were disclosed illustrate some important lessons about security vulnerabilities in general and email security in particular.
But first, if you use PGP or S/MIME to encrypt email, you need to check the list on this page and see if you are vulnerable. If you are, check with the vendor to see if they've fixed the vulnerability.
The real issue is overall trust.
Earlier this month, the Pentagon stopped selling phones made by the Chinese companies ZTE and Huawei on military bases because they might be used to spy on their users.
It's a legitimate fear, and perhaps a prudent action. But it's just one instance of the much larger issue of securing our supply chains.
All of our computerized systems are deeply international, and we have no choice but to trust the companies and governments that touch those systems.
Elections serve two purposes. The first, and obvious, purpose is to accurately choose the winner. But the second is equally important: to convince the loser. To the extent that an election system is not transparently and auditably accurate, it fails in that second purpose.
In the wake of the Cambridge Analytica scandal, news articles and commentators have focused on what Facebook knows about us. A lot, it turns out. It collects data from our posts, our likes, our photos, things we type and delete without posting, and things we do while not on Facebook and even when we're offline. It buys data about us from others.
Artificial intelligence technologies have the potential to upend the longstanding advantage that attack has over defense on the Internet. This has to do with the relative strengths and weaknesses of people and computers, how those all interplay in Internet security, and where AI technologies might change things.
You can divide Internet security tasks into two sets: what humans do well and what computers do well. Traditionally, computers excel at speed, scale, and scope.
This essay appeared as half of a point/counterpoint with Priscilla Regan, in a CQ Researcher report on Privacy and the Internet.
Everything online is hackable. This is true for Equifax's data and the federal Office of Personal Management's data, which was hacked in 2015. If information is on a computer connected to the internet, it is vulnerable.
But just because everything is hackable doesn't mean everything will be hacked.
What the battle looks like after Section 702's reauthorization
For over a decade, civil libertarians have been fighting government mass surveillance of innocent Americans over the Internet. We've just lost an important battle. On Jan. 18, when President Trump signed the renewal of Section 702, domestic mass surveillance became effectively a permanent part of U.S. law.
