Google is bringing voice-free emergency operator access to Android

Published

on

Google today highlighted a new feature that will bring voice-free emergency service interaction to Pixels and other Android devices. Designed for instances of injury, situations where speaking can present a danger and for users with speech impairments, the feature allows callers to communicate via touch menus.

Once an emergency call is triggered, users can specify its nature by tapping “Fire,” “Medical” or “Police.” That information is passed along to an operator without requiring the caller to speak, alongside location information that pulls from the phone’s GPS and uses plus code, a method for locating callers without a specific address.

The menu information is stored locally on the phone, and all of the information shared remains confidential, shared only with the emergency operator. Once the information is entered, users can also speak directly to the operator if able.

The feature was created in collaboration with the National Emergency Number Association. It’s arriving on Pixel phones and select Android devices in the U.S. in the coming months.

China’s and Russia’s spying spree will take years to unpack

Published

on

First it was SolarWinds, a reportedly Russian hacking campaign that stretches back almost a year and has felled at least nine US government agencies and countless private companies. Now it’s Hafnium, a Chinese group that’s been attacking a vulnerability in Microsoft Exchange Server to sneak into victims’ email inboxes and beyond. The collective toll of these espionage sprees is still being uncovered. It may never be fully known.

Countries spy on each other, everywhere, all the time. They always have. But the extent and sophistication of Russia’s and China’s latest efforts still manage to shock. And the near-term fallout of both underscores just how tricky it can be to take the full measure of a campaign even after you’ve sniffed it out.

By now you’re probably familiar with the basics of the SolarWinds attack: Likely Russian hackers broke into the IT management firm’s networks and altered versions of its Orion network monitoring tool, exposing as many as 18,000 organizations. The actual number of SolarWinds victims is assumed to be much smaller, although security analysts have pegged itin at least the low hundreds so far. And as SolarWinds CEO Sudhakar Ramakrishna has eagerly pointed out to anyone who will listen, his was not the only software supply chain company that the Russians hacked in this campaign, implying a much broader ecosystem of victims than anyone has yet accounted for.

“It’s become clear that there’s much more to learn about this incident, its causes, its scope, its scale, and where we go from here,” said Senate Intelligence Committee chair Mark Warner (D-Virginia) at a hearing related to the SolarWinds hack last week. Brandon Wales, acting director of the US Cybersecurity and Infrastructure Agency, estimated in an interview with MIT Technology Review this week that it could take up to 18 months for US government systems alone to recover from the hacking spree, to say nothing of the private sector.

That lack of clarity goes double for the Chinese hacking campaign that Microsoft disclosed Tuesday. First spotted by security firm Volexity, a nation-state group that Microsoft calls Hafnium has been using multiple zero-day exploits—which attack previously unknown vulnerabilities in software—to break into Exchange Servers, which manage email clients including Outlook. There, they could surreptitiously read through the email accounts of high-value targets.

Windows.com bitsquatting hack can wreak “unknown havoc” on PCs

Published

Bit flips are events that cause individual bits stored in an electronic device to flip, turning a 0 to a 1 or vice versa. Cosmic radiation and fluctuations in power or temperature are the most common naturally occurring causes. Research from 2010 estimated that a computer with 4GB of commodity RAM has a 96 percent chance of experiencing a bit flip within three days.

An independent researcher recently demonstrated how bitflips can come back to bite Windows users when their PCs reach out to Microsoft’s windows.com domain. Windows devices do this regularly to do things like making sure the time shown in the computer clock is accurate, connecting to Microsoft’s cloud-based services, and recovering from crashes.

Remy, as the researcher asked to be referred to, mapped the 32 valid domain names that were one bitflip away from windows.com. He provided the following to help readers understand how these flips can cause the domain to change to whndows.com:

01110111 01101001 01101110 01100100 01101111 01110111 01110011
w i n d o w s
01110111 01101000 01101110 01100100 01101111 01110111 01110011
w h n d o w s

Of the 32 bit-flipped values that were valid domain names, Remy found that 14 of them were still available for purchase. This was surprising because normally, Microsoft and other companies buy these types of one-off domains to protect customers against phishing attacks. He bought them for $126 and set out to see what would happen. The domains were:

  • windnws.com
  • windo7s.com
  • windkws.com
  • windmws.com
  • winlows.com
  • windgws.com
  • wildows.com
  • wintows.com
  • wijdows.com
  • wiodows.com
  • wifdows.com
  • whndows.com
  • wkndows.com
  • wmndows.com

No inherent verification

Over the course of two weeks, Remy’s server received 199,180 connections from 626 unique IP addresses that were trying to contact ntp.windows.com. By default, Windows machines will connect to this domain once per week to check that the time shown in the device clock is correct. What the researcher found next was even more surprising.

“The NTP client for windows OS has no inherent verification of authenticity, so there is nothing stopping a malicious person from telling all these computers that it’s after 03:14:07 on Tuesday, 19 January 2038 and wreaking unknown havoc as the memory storing the signed 32-bit integer for time overflows,” he wrote in a post summarizing his findings. “As it turns out though, for ~30% of these computers doing that would make little to no difference at all to those users because their clock is already broken.”

The researcher observed machines trying to make connections to other windows.com subdomains, including sg2p.w.s.windows.com, client.wns.windows.com, skydrive.wns.windows.com, windows.com/stopcode, and windows.com/?fbclid.

Remy said that not all of the domain mismatches were the result of bitflips. In some cases they were caused by typos by people behind the keyboard, and in at least one case the keyboard was on an Android device, as it attempted to diagnose a blue-screen-of-death crash that had occurred on a Windows machine.

To capture the traffic devices sent to the mismatched domains, Remy rented a virtual private server and created wildcard domain lookup entries to point to them. The wildcard records allow traffic destined for different subdomains of the same domain—say, ntp.whndows.com, abs.xyz.whndows.com, or client.wns.whndows.com—to map to the same IP address.

“Due to the nature of this research dealing with bits being flipped, this allows me to capture any DNS lookup for a subdomain of windows.com where multiple bits have flipped.”

Remy said he’s willing to transfer the 14 domains to a “verifiably responsible party” and in the meantime will simply sinkhole them, meaning he will hold onto the addresses and configure the DNS records so they are unreachable.

“Hopefully this spawns more research”

I asked Microsoft representatives if they’re aware of the findings and the offer to transfer the domains. The representatives are working on getting a response. Readers should remember, though, that the threats the research identifies aren’t limited to Windows.

In a 2019 presentation at the Kaspersky Security Analysts Summit, for instance, researchers from security firm Bishop Fox obtained some eye-opening results after registering hundreds of bitflipped variations of skype.com, symantec.com, and other widely visited sites.

Remy said the findings are important because they suggest that bitflip-induced domain mismatches occur at a scale that’s higher than many people realized.

“Prior research primarily dealt with HTTP/HTTPS, but my research shows that even with a small handful of bitsquatted domains you can still siphon up ill-destined traffic from other default network protocols that are constantly running, such as NTP,” Remy said in a direct message. “Hopefully this spawns more research into this area as it relates to the threat model of default OS services.”

SpaceX Starlink factory in Texas will speed up production of Dishy McFlatface

Published

on

Enlarge / The SpaceX Starlink satellite dish partway through a teardown.

SpaceX says it is building a factory in Austin, Texas, to design systems that will help make satellite dishes, Wi-Fi routers, and other equipment for its Starlink satellite broadband network. The news comes from a job posting for an automation and controls engineer position flagged in a story Tuesday by local news channel KXAN.

“To keep up with global demand, SpaceX is breaking ground on a new, state of the art manufacturing facility in Austin, TX,” the job posting said. “The Automation & Controls Engineer will play a key role as we strive to manufacture millions of consumer facing devices that we ship directly to customers (Starlink dishes, Wi-Fi routers, mounting hardware, etc).”

The factory apparently won’t make the dishes and routers on site but will instead design systems that improve the manufacturing process. “Specifically, they will design and develop control systems and software for production line machinery—ultimately tackling the toughest mechanical, software, and electrical challenges that come with high-volume manufacturing, all while maintaining a focus on flexibility, reliability, maintainability, and ease of use,” the job posting said.

Starlink is in beta and is serving over 10,000 customers, and it has asked the Federal Communications Commission for permission to deploy up to 5 million user terminals in the US. SpaceX calls this piece of hardware “Dishy McFlatface,” and it receives transmissions from SpaceX’s low-Earth orbit satellites. See our article about a Dishy McFlatface teardown for more details on the hardware’s inner portions, and this article for more pictures of the dish in its fully intact state.

Starlink has been charging $99 per month plus a one-time fee of $499 for the user terminal, mounting tripod, and router. Starlink recently began taking preorders for service that would become available in the second half of 2021.

Shipping to 25 countries this year

The new job posting said the successful applicant will work in Austin but spend up to 25 percent of the time at SpaceX headquarters in Los Angeles “until [the] Austin facility is fully established.” The new engineer will make an impact on Starlink’s ability to ship hardware this year. The person will “set, implement, and maintain schedules and budgets to ensure project completion as we strive to ship to 25+ countries by the end of the year,” the job posting said.

The engineer will be expected to “design, develop, and manage automation and controls projects to manufacture consumer electronics that are easy for humans around the world to use, but are technically very sophisticated—this includes initial factory ideation, on-line commissioning and proof of rate capability, and eventual hand-off to operational teams.” The engineer will also “spearhead facility bring up and initial equipment conceptual development by carefully balancing product specifications, process requirements, layout complexity, cost, and lead-time limits,” the job posting said.

We asked SpaceX for more detail on plans for the Austin facility and when it will open, and on where exactly the dishes and routers will be manufactured. We’ll update this article if we get an answer.

The new SpaceX factory would be near Tesla’s planned car factory in Austin. SpaceX founder and CEO Elon Musk is also the CEO of Tesla.
