Over a quarter of US adults now own a smart speaker, typically an Amazon Echo – TechCrunch

Published

on

U.S. smart speaker owners grew 40 percent over 2018 to now reach 66.4 million — or 26.2 percent of the U.S. adult population — according to a new report from Voicebot.ai and Voicify released this week, which detailed adoption patterns and device market share. The report also reconfirmed Amazon Echo’s lead, noting the Alexa-powered smart speaker grew to a 61 percent market share by the end of last year — well above Google Home’s 24 percent share.

These findings fall roughly in line with other analysts’ reports on smart speaker market share in the U.S. However, because of varying methodology, they don’t all come back with the exact same numbers.

For example, in December 2018, eMarketer reported the Echo had accounted for nearly 67 percent of all U.S. smart speaker sales in 2018. Meanwhile, CIRP last month put Echo further ahead, with a 70 percent share of the installed base in the U.S.

Though the percentages differ, the overall trend is that Amazon Echo remains the smart speaker to beat.

While on the face of things this appears to be great news for Amazon, Voicebot’s report did note that Google Home has been closing the gap with Echo in recent months.

Amazon Echo’s share dropped nearly 11 percent over 2018, while Google Home made up for just over half that decline with a 5.5 percent gain, and “other” devices making up the rest. This latter category, which includes devices like Apple’s HomePod and Sonos One, grew last year to now account for 15 percent of the market.

That said, the Sonos One has Alexa built-in, so it may not be as bad for Amazon as the numbers alone seem to indicate. After all, Amazon is selling its Echo devices at cost or even a loss to snag more market share. The real value over time will be in controlling the ecosystem.

The growth in smart speakers is part of a larger trend toward voice computing and smart voice assistants — like Siri, Bixby and Google Assistant — which are often accessed on smartphones.

A related report from Juniper Research last month estimated there will be 8 billion digital voice assistants in use by 2023, up from the 2.5 billion in use at the end of 2018. This is due to the increased use of smartphone assistants as well as the smart speaker trend, the firm said.

Voicebot’s report also saw how being able to access voice assistance on multiple platforms was helping to boost usage numbers.

It found that smart speaker owners used their smartphone’s voice assistant more than those who didn’t have a smart speaker in their home. It seems consumers get used to being able to access their voice assistants across platforms — now that Siri has made the jump to speakers and Alexa to phones, for instance.

The Google Assistant is now a Google messaging service

Published

on

The Google Assistant’s “Broadcast” feature has long existed as a way to blast a message to every Google smart speaker in the house. Instead of hunting down every individual family member at dinner time, put those smart speakers to work by saying, “Hey Google, broadcast, ‘It’s dinner time!'”

In a new blog post, Google called Broadcast “one of our most popular Assistant features” and announced that the feature is expanding to show messages on phones, too, even when they’re outside the home Wi-Fi network. That means Broadcast is basically turning into a new Google messaging service.

Broadcast will now be able to send and receive messages on the Google Home and Nest smart speakers, the Google Home Hub and Nest Hub smart displays, any Android phone, and iPhones running the Google Assistant app. Phones will get a notification when new messages arrive, and group chat members include both individual people (presumably with personal devices like a phone) and more public home devices. Just like any other messaging service, opening the notification will show a scrolling list of broadcast messages. The one big limitation is that the messaging only happens within a Google Family Group. If you want to include an outsider, you’ll have to awkwardly switch group messaging services.

Broadcast messaging uses audio by default, so speakers and smart displays will play the voice recording of your message. Phones and smart displays will show a transcription of your message and a play button, so you can listen or read if you want, and it looks like phones have the option of typing a response, too. Presumably, this would play back on speakers using text-to-speech.

One of many bespoke Google messaging services

Google has never been able to throw its full weight behind a single messaging service, and the constant launching and shutting down of competing messaging services has left the company without a competitive messaging platform to back. Several Google apps like the Google Assistant have aimed to include some smaller messaging functionality over the years, but without a clear Google service to plug into, they end up spinning up their own bespoke messaging services.

Besides this Google Assistant messaging service, YouTube Messaging existed from 2017-2019, Google Maps Messages (to message businesses) launched in 2018, Google Photos Messaging launched in 2019, Stadia Messaging was added in 2020, and Google Pay Messaging came out of beta with the app revamp in March 2021. And who could forget Google Docs Chat, which has existed seemingly forever, though awkwardly only on desktop clients. We can also give half-credit to Google News, which lets you send a message with a shared news article and will pop up a notification through the Google News app, although the feature doesn’t support replies. It would be nice if any of these services talked to each other through a single Google Messaging service, but instead, you’ll be managing individual contact lists and message histories.

This is one of a few new Google Assistant features that is supposed to arrive “just in time” for Mother’s Day (this Sunday—you all remembered, right?) so it should be rolling out soon.

Fix for critical Qualcomm chip flaw is making its way to Android devices

Published

Makers of high-end Android devices are responding to the discovery of a Qualcomm chip flaw that researchers say could be exploited to partially backdoor about a third of the world’s smartphones.

The vulnerability, discovered by researchers from security firm Check Point Research, resides in Qualcomm’s Mobile Station Modem, a system of chips that provides capabilities for things like voice, SMS, and high-definition recording, mostly on higher-end devices made by Google, Samsung, LG, Xiaomi, and OnePlus. Phone-makers can customize the chips so they do additional things like handle SIM unlock requests. The chips run in 31 percent of the world’s smartphones, according to figures from Counterpoint Research.

The heap overflow the researchers found can be exploited by a malicious app installed on the phone, and from there the app can plant malicious code inside the MSM, Check Point researchers said in a blog post published Thursday. The nearly undetectable code might then be able to tap into some of a phone’s most vital functions.

“This means an attacker could have used this vulnerability to inject malicious code into the modem from Android, giving them access to the device user’s call history and SMS, as well as the ability to listen to the device user’s conversations,” the researchers wrote. “A hacker can also exploit the vulnerability to unlock the device’s SIM, thereby overcoming the limitations imposed by service providers on it.”

Fixes take time

Check Point spokesman Ekram Ahmed told me that Qualcomm has released a patch and disclosed the bug to all customers who use the chip. Because of the intricacies involved, it’s not yet clear which vulnerable Android devices are fixed and which ones aren’t.

“From our experience, the implementation of these fixes takes time, so some of the phones may still be prone to the threat,” he wrote in an email. “Accordingly, we decided not to share all the technical details, as it would give hackers a roadmap on how to orchestrate an exploitation.”

Qualcomm representatives weren’t available on Wednesday evening to answer questions.

The vulnerability is tracked as CVE-2020-11292. Check Point discovered it by using a process known as fuzzing, which exposed the chip system to unusual inputs in an attempt to find bugs in the firmware. Thursday’s research provides a deep dive into the inner workings of the chip system and the general outline they used to exploit the vulnerability.

The research is a reminder that phones and other modern-day computing devices are actually a collection of dozens if not hundreds of interconnected computing devices. While successfully infecting individual chips typically requires nation-state-level hacking resources, the feat would allow an attacker to run malware that couldn’t be detected without time and money.

“We believe this research to be a potential leap in the very popular area of mobile chip research,” Check Point researchers wrote. “Our hope is that our findings will pave the way for a much easier inspection of the modem code by security researchers, a task that is notoriously hard to do today.”

Dell patches a 12-year-old privilege escalation vulnerability

Published

on

Enlarge / At least three companies have reported the dbutil_2_3.sys security problems to Dell over the past two years.

Yesterday, infosec research firm SentinelLabs revealed twelve year old flaws in Dell’s firmware updater, DBUtil 2.3. The vulnerable firmware updater has been installed by default on hundreds of millions of Dell systems since 2009.

The five high severity flaws SentinelLabs discovered and reported to Dell lurk in the dbutil_2_3.sys module, and have been rounded up under a single CVE tracking number, CVE-2021-21551. There are two memory corruption issues and two lack of input validation issues, all of which can lead to local privilege escalation, and a code logic issue which could lead to a denial of service.

A hypothetical attacker abusing these vulnerabilities can escalate the privileges of another process, or bypass security controls to write directly to system storage. This offers multiple routes to the ultimate goal of local kernel-level access—a step even higher than Administrator or “root” access—to the entire system.

This is not a remote code execution vulnerability—an attacker sitting across the world, or even across the coffee shop, cannot use it directly to compromise your system. The major risk is that an attacker who gets an unprivileged shell via some other vulnerability can use a local privilege escalation exploit like this one to bypass security controls.

Since SentinelLabs notified Dell in December 2020, the company has provided documentation of the flaws, and mitigation instructions which for now boil down to “remove the utility.” A replacement driver is also available, and should be automatically installed at the next firmware update check on affected Dell systems.

SentinelLabs’ Kasif Dekel was at least the fourth researcher to discover and report this issue, following CrowdStrike’s Satoshi Tanda and Yarden Shafir, and IOActive’s Enrique Nissim. It’s not clear why it took Dell two years and three separate infosec companies’ reports to patch the issue—but to paraphrase CrowdStrike’s Alex Ionescu above, what matters most is that Dell’s users will finally be protected.
