We’ve often heard security folks explain their belief that one of the best ways to protect Web privacy and security on one's home turf is to lock down one's private Wi-Fi network with a strong password. But a coalition of advocacy organizations is calling such conventional wisdom into question. Members of the “Open Wireless Movement,” including the Electronic Frontier Foundation (EFF), Free Press, Mozilla, and Fight for the Future are advocating that we open up our Wi-Fi private networks (or at least a small slice of our available bandwidth) to strangers. They claim that such a random act of kindness can actually make us safer online while simultaneously facilitating a better allocation of finite broadband resources. The OpenWireless.org website explains the group’s initiative. “We are aiming to build technologies that would make it easy for Internet subscribers to portion off their wireless networks for guests and the public while maintaining security, protecting privacy, and preserving quality of access," its mission statement reads. "And we are working to debunk myths (and confront truths) about open wireless while creating technologies and legal precedent to ensure it is safe, private, and legal to open your network.”

One such technology, which EFF plans to unveil at the Hackers on Planet Earth (HOPE X) conference next month, is open-sourced router firmware called Open Wireless Router. This firmware would enable individuals to share a portion of their Wi-Fi networks with anyone nearby, password-free, as Adi Kamdar, an EFF activist, told Ars on Friday. Home network sharing tools are not new, and the EFF has been touting the benefits of open-sourcing Web connections for years, but Kamdar believes this new tool marks the second phase in the open wireless initiative. Unlike previous tools, he claims, EFF’s software will be free for all, will not require any sort of registration, and will actually make surfing the Web safer and more efficient.

Kamdar said that the new firmware utilizes smart technologies that prioritize the network owner's traffic over others', so good samaritans won't have to wait for Netflix to load because of strangers using their home networks. What's more, he said, "every connection is walled off from all other connections," so as to decrease the risk of unwanted snooping. Additionally, EFF hopes that opening one’s Wi-Fi network will, in the long run, make it more difficult to tie an IP address to an individual. “From a legal perspective, we have been trying to tackle this idea that law enforcement and certain bad plaintiffs have been pushing, that your IP address is tied to your identity. Your identity is not your IP address. You shouldn't be targeted by a copyright troll just because they know your IP address," said Kamdar.

Some time on Tuesday afternoon, about 50,000 Comcast Internet customers in Houston will become part of a massive public Wi-Fi hotspot network, a number that will swell to 150,000 by the end of June. Comcast will begin activating a feature in its Arris Touchstone Telephony Wireless Gateway Modems that sets up a public Wi-Fi hotspot alongside a residential Internet customer’s private home network. Other Comcast customers will be able to log in to the hotspots for free using a computer, smartphone or other mobile device. And once they log into one, they’ll be automatically logged in to others when their devices “see” them. Comcast says the hotspot – which appears as “xfinitywifi” to those searching for a Wi-Fi connection – is completely separate from the home network. Someone accessing the Net through the hotspot can’t get to the computers, printers, mobile devices, streaming boxes and more sitting on the host network. Comcast officials also say that people using the Internet via the hotspot won’t slow down Internet access on the home network. Additional capacity is allotted to handle the bandwidth. You can read more about Comcast’s reason for doing this in my report on HoustonChronicle.com.

What’s interesting about this move is that, by default, the feature is being turned on without its subscribers’ prior consent. It’s an opt-out system – you have to take action to not participate. Comcast spokesman Michael Bybee said on Monday that notices about the hotspot feature were mailed to customers a few weeks ago, and email notifications will go out after it’s turned on. But it’s a good bet that this will take many Comcast customers by surprise. If you have one of these routers and don’t want to host a public Wi-Fi hotspot, here’s how to turn it off.

The additional capacity for public hotspot users is provided through a separate channel on the modem called a “service flow,” according to Comcast. But the speed of the connection reflects the tier of the subscriber hosting the hotspot. For example, if you connect to a hotspot hosted by a home user with a 25-Mbps connection, it will be slower than if you connect to a host system on the 50-Mbps tier.

Brian Krebs is a popular reporter on the cybersecurity beat. He regularly exposes cybercriminals and their tactics, and consequently is regularly a target of their ire. Last month, he wrote about an online attack-for-hire service that resulted in the arrest of the two proprietors. In the aftermath, his site was taken down by a massive DDoS attack.In many ways, this is nothing new. Distributed denial-of-service attacks are a family of attacks that cause websites and other internet-connected systems to crash by overloading them with traffic. The "distributed" part means that other insecure computers on the internet—sometimes in the millions—are recruited to a botnet to unwittingly participate in the attack. The tactics are decades old; DDoS attacks are perpetrated by lone hackers trying to be annoying, criminals trying to extort money, and governments testing their tactics. There are defenses, and there are companies that offer DDoS mitigation services for hire. Basically, it's a size vs. size game. If the attackers can cobble together a fire hose of data bigger than the defender's capability to cope with, they win. If the defenders can increase their capability in the face of attack, they win. What was new about the Krebs attack was both the massive scale and the particular devices the attackers recruited. Instead of using traditional computers for their botnet, they used CCTV cameras, digital video recorders, home routers, and other embedded computers attached to the internet as part of the Internet of Things. Much has been written about how the IoT is wildly insecure. In fact, the software used to attack Krebs was simple and amateurish. What this attack demonstrates is that the economics of the IoT mean that it will remain insecure unless government steps in to fix the problem. This is a market failure that can't get fixed on its own.

It's an uncertain waiting game as to when the next-generation high-speed wireless service known as 5G will reach mass market, but the business implications are already a major talking point at CES 2018.

The term "5G" refers to the fifth-generation wireless broadband technology based on the 802.11ac standard. The packet of technology will bring speed and coverage improvements from 4G, with low-latency wireless up to 1GB/s, and it'll spur a host of new opportunities for enterprises and workplace productivity.In a panel discussion at CES, a trio of executives from Qualcomm, Ericsson, and Nokia discussed how 5G could transform industries ranging from transportation to manufacturing.

Some 5G rollouts are already planned for 2018. Samsung announced last Wednesday that it will provide Verizon with routers and radio frequency planning services for the carrier's initial 5G commercial rollout that will begin in Sacramento, Calif., in the second half of 2018.Meanwhile, AT&T announced that it will provide 5G services in roughly 12 markets by late 2018, with plans to offer the service to consumers while it trials 5G technology with businesses across all industries.Still, the panel of executives at CES remain skeptical that 5G would roll out for most Americans before late 2019 or 2020.

As fast as it can, Google is sealing up cracks in its systems that Edward J. Snowden revealed the N.S.A. had brilliantly exploited. It is encrypting more data as it moves among its servers and helping customers encode their own emails. Facebook, Microsoft and Yahoo are taking similar steps.

After years of cooperating with the government, the immediate goal now is to thwart Washington — as well as Beijing and Moscow. The strategy is also intended to preserve business overseas in places like Brazil and Germany that have threatened to entrust data only to local providers. Google, for example, is laying its own fiber optic cable under the world’s oceans, a project that began as an effort to cut costs and extend its influence, but now has an added purpose: to assure that the company will have more control over the movement of its customer data.

A year after Mr. Snowden’s revelations, the era of quiet cooperation is over. Telecommunications companies say they are denying requests to volunteer data not covered by existing law. A.T.&T., Verizon and others say that compared with a year ago, they are far more reluctant to cooperate with the United States government in “gray areas” where there is no explicit requirement for a legal warrant.

Warning of an erosion of confidence in the products of the U.S. technology industry, John Chambers, the CEO of networking giant Cisco Systems, has asked President Obama to intervene to curtail the surveillance activities of the National Security Agency. In a letter dated May 15 (obtained by Re/code and reprinted in full below), Chambers asked Obama to create “new standards of conduct” regarding how the NSA carries out its spying operations around the world. The letter was first reported by The Financial Times. The letter follows new revelations, including photos, published in a book based on documents leaked by former NSA contractor Edward Snowden alleging that the NSA intercepted equipment from Cisco and other manufacturers and loaded them with surveillance software. The photos, which have not been independently verified, appear to show NSA technicians working with Cisco equipment. Cisco is not said to have cooperated in the NSA’s efforts.

The NSA and Britain's GCHQ hacked the world's biggest SIM card maker to harvest the encryption keys needed to silently and effortlessly eavesdrop on potentially millions of people. That's according to documents obtained by surveillance whistleblower Edward Snowden and leaked to the web on Thursday. "Wow. This is huge – it's one of the most significant findings of the Snowden files so far," computer security guru Bruce Schneier told The Register this afternoon. "We always knew that they would occasionally steal SIM keys. But all of them? The odds that they just attacked this one firm are extraordinarily low and we know the NSA does like to steal keys where it can." The damning slides, published by Snowden's chums at The Intercept, detail the activities of the as-yet unheard-of Mobile Handset Exploitation Team (MHET), run by the US and UK. The group targeted Gemalto, which churns out about two billion SIM cards each year for use around the world, and targeted it in an operation dubbed DAPINO GAMMA.

Gemalto's hacking may also bring into question some of its other security products as well. The company supplies chips for electronic passports issued by the US, Singapore, India, and many European states, and is also involved in the NFC and mobile banking sector. It's important to note that this is useful for tracking the phone activity of a target, but the mobile user can still use encryption on the handset itself to ensure that some communications remain private. "Ironically one of your best defenses against a hijacked SIM is to use software encryption," Jon Callas, CTO of encrypted chat biz Silent Circle told The Register. "In our case there's a TCP/IP cloud between Alice and Bob and that can deal with compromised routers along the path as well as SIM issues, and the same applies to similar mobile software."

On Wednesday the UK government admitted that its intelligence agencies had in fact broken the ECHR when spying on communications between lawyers and those suing the British state, so GCHQ might want to reconsider that statement.

Micah Lee: What are some operational security practices you think everyone should adopt? Just useful stuff for average people. Edward Snowden: [Opsec] is important even if you’re not worried about the NSA. Because when you think about who the victims of surveillance are, on a day-to-day basis, you’re thinking about people who are in abusive spousal relationships, you’re thinking about people who are concerned about stalkers, you’re thinking about children who are concerned about their parents overhearing things. It’s to reclaim a level of privacy. The first step that anyone could take is to encrypt their phone calls and their text messages. You can do that through the smartphone app Signal, by Open Whisper Systems. It’s free, and you can just download it immediately. And anybody you’re talking to now, their communications, if it’s intercepted, can’t be read by adversaries. [Signal is available for iOS and Android, and, unlike a lot of security tools, is very easy to use.] You should encrypt your hard disk, so that if your computer is stolen the information isn’t obtainable to an adversary — pictures, where you live, where you work, where your kids are, where you go to school. [I’ve written a guide to encrypting your disk on Windows, Mac, and Linux.] Use a password manager. One of the main things that gets people’s private information exposed, not necessarily to the most powerful adversaries, but to the most common ones, are data dumps. Your credentials may be revealed because some service you stopped using in 2007 gets hacked, and your password that you were using for that one site also works for your Gmail account. A password manager allows you to create unique passwords for every site that are unbreakable, but you don’t have the burden of memorizing them. [The password manager KeePassX is free, open source, cross-platform, and never stores anything in the cloud.]

The other thing there is two-factor authentication. The value of this is if someone does steal your password, or it’s left or exposed somewhere … [two-factor authentication] allows the provider to send you a secondary means of authentication — a text message or something like that. [If you enable two-factor authentication, an attacker needs both your password as the first factor and a physical device, like your phone, as your second factor, to login to your account. Gmail, Facebook, Twitter, Dropbox, GitHub, Battle.net, and tons of other services all support two-factor authentication.]

We should armor ourselves using systems we can rely on every day. This doesn’t need to be an extraordinary lifestyle change. It doesn’t have to be something that is disruptive. It should be invisible, it should be atmospheric, it should be something that happens painlessly, effortlessly. This is why I like apps like Signal, because they’re low friction. It doesn’t require you to re-order your life. It doesn’t require you to change your method of communications. You can use it right now to talk to your friends.

Until just last week, the U.S. government kept up the charade that its use of a stockpile of security vulnerabilities for hacking was a closely held secret.1 In fact, in response to EFF’s FOIA suit to get access to the official U.S. policy on zero days, the government redacted every single reference to “offensive” use of vulnerabilities. To add insult to injury, the government’s claim was that even admitting to offensive use would cause damage to national security. Now, in the face of EFF’s brief marshaling overwhelming evidence to the contrary, the charade is over. In response to EFF’s motion for summary judgment, the government has disclosed a new version of the Vulnerabilities Equities Process, minus many of the worst redactions. First and foremost, it now admits that the “discovery of vulnerabilities in commercial information technology may present competing ‘equities’ for the [government’s] offensive and defensive mission.” That might seem painfully obvious—a flaw or backdoor in a Juniper router is dangerous for anyone running a network, whether that network is in the U.S. or Iran. But the government’s failure to adequately weigh these “competing equities” was so severe that in 2013 a group of experts appointed by President Obama recommended that the policy favor disclosure “in almost all instances for widely used code.” [.pdf].

The newly disclosed version of the Vulnerabilities Equities Process (VEP) also officially confirms what everyone already knew: the use of zero days isn’t confined to the spies. Rather, the policy states that the “law enforcement community may want to use information pertaining to a vulnerability for similar offensive or defensive purposes but for the ultimate end of law enforcement.” Similarly it explains that “counterintelligence equities can be defensive, offensive, and/or law enforcement-related” and may “also have prosecutorial responsibilities.” Given that the government is currently prosecuting users for committing crimes over Tor hidden services, and that it identified these individuals using vulnerabilities called a “Network Investigative Technique”, this too doesn’t exactly come as a shocker. Just a few weeks ago, the government swore that even acknowledging the mere fact that it uses vulnerabilities offensively “could be expected to cause serious damage to the national security.” That’s a standard move in FOIA cases involving classified information, even though the government unnecessarily classifies documents at an astounding rate. In this case, the government relented only after nearly a year and a half of litigation by EFF. The government would be well advised to stop relying on such weak secrecy claims—it only risks undermining its own credibility.

The new version of the VEP also reveals significantly more information about the general process the government follows when a vulnerability is identified. In a nutshell, an agency that discovers a zero day is responsible for invoking the VEP, which then provides for centralized coordination and weighing of equities among all affected agencies. Along with a declaration from an official at the Office of the Director of National Intelligence, this new information provides more background on the reasons why the government decided to develop an overarching zero day policy in the first place: it “recognized that not all organizations see the entire picture of vulnerabilities, and each organization may have its own equities and concerns regarding the prioritization of patches and fixes, as well as its own distinct mission obligations.” We now know the VEP was finalized in February 2010, but the government apparently failed to implement it in any substantial way, prompting the presidential review group’s recommendation to prioritize disclosure over offensive hacking. We’re glad to have forced a little more transparency on this important issue, but the government is still foolishly holding on to a few last redactions, including refusing to name which agencies participate in the VEP. That’s just not supportable, and we’ll be in court next month to argue that the names of these agencies must be disclosed. 

Earlier this March, cyber-security firm Kaspersky Labs released information on a newly discovered, highly advanced piece of malware dubbed Slingshot. The malware targeted Latvian-made Internet routers popular in the Middle East, Africa, and Southeast Asia. Kaspersky’s reports reveal that the malware had been active since at least 2012, and speculates that it was government-made, owing to its sophistication and its use of novel techniques rarely seen elsewhere. Those investigating the matter further have drawn the conclusion that Slingshot was developed by the U.S. government, with some reports quoting former officials as connecting it to the Pentagon’s JSOC special forces. For those following the cyber security and malware sphere, this is a huge revelation, putting the U.S. government in the hot seat for deploying cyber attacks that harm a much greater range of innocent users beyond their intended targets. Kaspersky’s own findings note that the code was written in English, using a driver flaw to allow the implanting of various types of spyware. Among those mentioned by Moscow-based Kaspersky was an implant named “GOLLUM,” which notably was mentioned in one of the leaked Edward Snowden documents. Further findings suggest that Slingshot had common code with only two other known pieces of software, both malwares, which were attributed to the NSA and CIA, respectively, by analysts. Though various U.S. agencies are all denying comment, things are clearly pointing uncomfortably in their direction.

Amidst an escalating trade war and political tensions with the US, Beijing officials have decided to develop a custom operating system that will replace the Windows OS on computers used by the Chinese military.

Beijing officials are well aware of the US' hefty arsenal of hacking tools, available for anything from smart TVs to Linux servers, and from routers to common desktop operating systems, such as Windows and Mac.Since these leaks have revealed that the US can hack into almost anything, the Chinese government's plan is to adopt a "security by obscurity" approach and run a custom operating system that will make it harder for foreign threat actors -- mainly the US -- to spy on Chinese military operations.
