There are indications that U.S. healthcare giant Change Healthcare has made a $22 million extortion payment to the infamous BlackCat ransomware group (a.k.a. “ALPHV“) as the company struggles to bring services back online amid a cyberattack that has disrupted prescription drug services nationwide for weeks. However, the cybercriminal who claims to have given BlackCat access to Change’s network says the crime gang cheated them out of their share of the ransom, and that they still have the sensitive data Change reportedly paid the group to destroy. Meanwhile, the affiliate’s disclosure appears to have prompted BlackCat to cease operations entirely.

In the third week of February, a cyber intrusion at Change Healthcare began shutting down important healthcare services as company systems were taken offline. It soon emerged that BlackCat was behind the attack, which has disrupted the delivery of prescription drugs for hospitals and pharmacies nationwide for nearly two weeks.
On March 1, a cryptocurrency address that security researchers had already mapped to BlackCat received a single transaction worth approximately $22 million. On March 3, a BlackCat affiliate posted a complaint to the exclusive Russian-language ransomware forum Ramp saying that Change Healthcare had paid a $22 million ransom for a decryption key, and to prevent four terabytes of stolen data from being published online.
The affiliate claimed BlackCat/ALPHV took the $22 million payment but never paid him his percentage of the ransom. BlackCat is known as a “ransomware-as-service” collective, meaning they rely on freelancers or affiliates to infect new networks with their ransomware. And those affiliates in turn earn commissions ranging from 60 to 90 percent of any ransom amount paid.
“But after receiving the payment ALPHV team decide to suspend our account and keep lying and delaying when we contacted ALPHV admin,” the affiliate “Notchy” wrote. “Sadly for Change Healthcare, their data [is] still with us.”
Change Healthcare has neither confirmed nor denied paying, and has responded to multiple media outlets with a similar non-denial statement — that the company is focused on its investigation and on restoring services.
Assuming Change Healthcare did pay to keep their data from being published, that strategy seems to have gone awry: Notchy said the list of affected Change Healthcare partners they’d stolen sensitive data from included Medicare and a host of other major insurance and pharmacy networks.
On the bright side, Notchy’s complaint seems to have been the final nail in the coffin for the BlackCat ransomware group, which was infiltrated by the FBI and foreign law enforcement partners in late December 2023. As part of that action, the government seized the BlackCat website and released a decryption tool to help victims recover their systems.
BlackCat responded by re-forming, and increasing affiliate commissions to as much as 90 percent. The ransomware group also declared it was formally removing any restrictions or discouragement against targeting hospitals and healthcare providers.
However, instead of responding that they would compensate and placate Notchy, a representative for BlackCat said today the group was shutting down and that it had already found a buyer for its ransomware source code.
The seizure notice now displayed on the BlackCat darknet website.
“There’s no sense in making excuses,” wrote the RAMP member “Ransom.” “Yes, we knew about the problem, and we were trying to solve it. We told the affiliate to wait. We could send you our private chat logs where we are shocked by everything that’s happening and are trying to solve the issue with the transactions by using a higher fee, but there’s no sense in doing that because we decided to fully close the project. We can officially state that we got screwed by the feds.”
BlackCat’s website now features a seizure notice from the FBI, but several researchers noted that this image seems to have been merely cut and pasted from the notice the FBI left in its December raid of BlackCat’s network. The FBI has not responded to requests for comment.
Fabian Wosar, head of ransomware research at the security firm Emsisoft, said it appears BlackCat leaders are trying to pull an “exit scam” on affiliates by withholding many ransomware payment commissions at once and shutting down the service.
“ALPHV/BlackCat did not get seized,” Wosar wrote on Twitter/X today. “They are exit scamming their affiliates. It is blatantly obvious when you check the source code of their new takedown notice.”
Dmitry Smilyanets, a researcher for the security firm Recorded Future, said BlackCat’s exit scam was especially dangerous because the affiliate still has all the stolen data, and could still demand additional payment or leak the information on his own.
“The affiliates still have this data, and they’re mad they didn’t receive this money, Smilyanets told Wired.com. “It’s a good lesson for everyone. You cannot trust criminals; their word is worth nothing.”
BlackCat’s apparent demise comes closely on the heels of the implosion of another major ransomware group — LockBit, a ransomware gang estimated to have extorted over $120 million in payments from more than 2,000 victims worldwide. On Feb. 20, LockBit’s website was seized by the FBI and the U.K.’s National Crime Agency (NCA) following a months-long infiltration of the group.
LockBit also tried to restore its reputation on the cybercrime forums by resurrecting itself at a new darknet website, and by threatening to release data from a number of major companies that were hacked by the group in the weeks and days prior to the FBI takedown.
But LockBit appears to have since lost any credibility the group may have once had. After a much-promoted attack on the government of Fulton County, Ga., for example, LockBit threatened to release Fulton County’s data unless paid a ransom by Feb. 29. But when Feb. 29 rolled around, LockBit simply deleted the entry for Fulton County from its site, along with those of several financial organizations that had previously been extorted by the group.
Fulton County held a press conference to say that it had not paid a ransom to LockBit, nor had anyone done so on their behalf, and that they were just as mystified as everyone else as to why LockBit never followed through on its threat to publish the county’s data. Experts told KrebsOnSecurity LockBit likely balked because it was bluffing, and that the FBI likely relieved them of that data in their raid.
Smilyanets’ comments are driven home in revelations first published last month by Recorded Future, which quoted an NCA official as saying LockBit never deleted the data after being paid a ransom, even though that is the only reason many of its victims paid.
“If we do not give you decrypters, or we do not delete your data after payment, then nobody will pay us in the future,” LockBit’s extortion notes typically read.
Hopefully, more companies are starting to get the memo that paying cybercrooks to delete stolen data is a losing proposition all around.
Malicious hackers are targeting people in the cryptocurrency space in attacks that start with a link added to the target’s calendar at Calendly, a popular application for scheduling appointments and meetings. The attackers impersonate established cryptocurrency investors and ask to schedule a video conference call. But clicking the meeting link provided by the scammers prompts the user to run a script that quietly installs malware on macOS systems.
KrebsOnSecurity recently heard from a reader who works at a startup that is seeking investment for building a new blockchain platform for the Web. The reader spoke on condition that their name not be used in this story, so for the sake of simplicity we’ll call him Doug.
Being in the cryptocurrency scene, Doug is also active on the instant messenger platform Telegram. Earlier this month, Doug was approached by someone on Telegram whose profile name, image and description said they were Ian Lee, from Signum Capital, a well-established investment firm based in Singapore. The profile also linked to Mr. Lee’s Twitter/X account, which features the same profile image.
The investor expressed interest in financially supporting Doug’s startup, and asked if Doug could find time for a video call to discuss investment prospects. Sure, Doug said, here’s my Calendly profile, book a time and we’ll do it then.
When the day and time of the scheduled meeting with Mr. Lee arrived, Doug clicked the meeting link in his calendar but nothing happened. Doug then messaged the Mr. Lee account on Telegram, who said there was some kind of technology issue with the video platform, and that their IT people suggested using a different meeting link.
Doug clicked the new link, but instead of opening up a videoconference app, a message appeared on his Mac saying the video service was experiencing technical difficulties.
“Some of our users are facing issues with our service,” the message read. “We are actively working on fixing these problems. Please refer to this script as a temporary solution.”
Doug said he ran the script, but nothing appeared to happen after that, and the videoconference application still wouldn’t start. Mr. Lee apologized for the inconvenience and said they would have to reschedule their meeting, but he never responded to any of Doug’s follow-up messages.
It didn’t dawn on Doug until days later that the missed meeting with Mr. Lee might have been a malware attack. Going back to his Telegram client to revisit the conversation, Doug discovered his potential investor had deleted the meeting link and other bits of conversation from their shared chat history.
In a post to its Twitter/X account last month, Signum Capital warned that a fake profile pretending to be their employee Mr. Lee was trying to scam people on Telegram.
The file that Doug ran is a simple Apple Script (file extension “.scpt”) that downloads and executes a malicious trojan made to run on macOS systems. Unfortunately for us, Doug freaked out after deciding he’d been tricked — backing up his important documents, changing his passwords, and then reinstalling macOS on his computer. While this a perfectly sane response, it means we don’t have the actual malware that was pushed to his Mac by the script.
But Doug does still have a copy of the malicious script that was downloaded from clicking the meeting link (the online host serving that link is now offline). A search in Google for a string of text from that script turns up a December 2023 blog post from cryptocurrency security firm SlowMist about phishing attacks on Telegram from North Korean state-sponsored hackers.
“When the project team clicks the link, they encounter a region access restriction,” SlowMist wrote. “At this point, the North Korean hackers coax the team into downloading and running a ‘location-modifying’ malicious script. Once the project team complies, their computer comes under the control of the hackers, leading to the theft of funds.”

SlowMist says the North Korean phishing scams used the “Add Custom Link” feature of the Calendly meeting scheduling system on event pages to insert malicious links and initiate phishing attacks.
“Since Calendly integrates well with the daily work routines of most project teams, these malicious links do not easily raise suspicion,” the blog post explains. “Consequently, the project teams may inadvertently click on these malicious links, download, and execute malicious code.”
SlowMist said the malware downloaded by the malicious link in their case comes from a North Korean hacking group dubbed “BlueNoroff, which Kaspersky Labs says is a subgroup of the Lazarus hacking group.
“A financially motivated threat actor closely connected with Lazarus that targets banks, casinos, fin-tech companies, POST software and cryptocurrency businesses, and ATMs,” Kaspersky wrote of BlueNoroff in Dec. 2023.
The North Korean regime is known to use stolen cryptocurrencies to fund its military and other state projects. A recent report from Recorded Future finds the Lazarus Group has stolen approximately $3 billion in cryptocurrency over the past six years.
While there is still far more malware out there today targeting Microsoft Windows PCs, the prevalence of information-stealing trojans aimed at macOS users is growing at a steady clip. MacOS computers include X-Protect, Apple’s built-in antivirus technology. But experts say attackers are constantly changing the appearance and behavior of their malware to evade X-Protect.
“Recent updates to macOS’s XProtect signature database indicate that Apple are aware of the problem, but early 2024 has already seen a number of stealer families evade known signatures,” security firm SentinelOne wrote in January.
According to Chris Ueland from the threat hunting platform Hunt.io, the Internet address of the fake meeting website Doug was tricked into visiting (104.168.163,149) hosts or very recently hosted about 75 different domain names, many of which invoke words associated with videoconferencing or cryptocurrency. Those domains indicate this North Korean hacking group is hiding behind a number of phony crypto firms, like the six-month-old website for Cryptowave Capital (cryptowave[.]capital).
In a statement shared with KrebsOnSecurity, Calendly said it was aware of these types of social engineering attacks by cryptocurrency hackers.
“To help prevent these kinds of attacks, our security team and partners have implemented a service to automatically detect fraud and impersonations that could lead to social engineering,” the company said. “We are also actively scanning content for all our customers to catch these types of malicious links and to prevent hackers earlier on. Additionally, we intend to add an interstitial page warning users before they’re redirected away from Calendly to other websites. Along with the steps we’ve taken, we recommend users stay vigilant by keeping their software secure with running the latest updates and verifying suspicious links through tools like VirusTotal to alert them of possible malware. We are continuously strengthening the cybersecurity of our platform to protect our customers.”
The increasing frequency of new Mac malware is a good reminder that Mac users should not depend on security software and tools to flag malicious files, which are frequently bundled with or disguised as legitimate software.
As KrebsOnSecurity has advised Windows users for years, a good rule of safety to live by is this: If you didn’t go looking for it, don’t install it. Following this mantra heads off a great deal of malware attacks, regardless of the platform used. When you do decide to install a piece of software, make sure you are downloading it from the original source, and then keep it updated with any new security fixes.
On that last front, I’ve found it’s a good idea not to wait until the last minute to configure my system before joining a scheduled videoconference call. Even if the call uses software that is already on my computer, it is often the case that software updates are required before the program can be used, and I’m one of those weird people who likes to review any changes to the software maker’s privacy policies or user agreements before choosing to install updates.
Most of all, verify new contacts from strangers before accepting anything from them. In this case, had Doug simply messaged Mr. Lee’s real account on Twitter/X or contacted Signum Capital directly, he would discovered that the real Mr. Lee never asked for a meeting.
If you’re approached in a similar scheme, the response from the would-be victim documented in the SlowMist blog post is probably the best.

Update: Added comment from Calendly.
Here’s one way you can help reduce your chances of identity theft: remove your personal information from the internet.
And chances are, you have more personal information posted online than you think.
According to the U.S. Federal Trade Commission (FTC), consumers registered 1.4 million identity theft complaints in 2021, all part of a year where consumers reported losing $5.8 billion to fraud overall—a 70% increase over the year prior.
What fuels all this theft and fraud? Access to personal information.
Scammers and thieves can get a hold of personal information in several ways, such as through phishing attacks that lure you into handing it over, malware that steals it from your devices, by purchasing your information on dark web marketplaces, or as a result of information leaked in data breaches, just to name a few.
However, scammers and thieves have other resources to help them commit theft and fraud—data broker sites, places where personal information is posted online for practically anyone to see. Which makes removing your info from them so important, from both an identity and privacy standpoint.
Think of data broker sites as huge repositories of personal information. Search your name and address online and you’ll see. You’ll likely find dozens of sites that turn up information about you, some of which offer a few pieces for free and others that offer far more information for a price.
Data brokers collect and then aggregate personal information from several sources, including:
Data brokers also buy personal information from other data brokers. As a result, some data brokers have thousands of pieces of data for billions of individuals worldwide.
What could that look like? A broker may know how much you paid for your home, your education level, where you’ve lived over the years and who your lived with, your driving record, and possibly your political leanings. A broker may also know your favorite flavor of ice cream and your preferred over-the-counter allergy medicine thanks to information from loyalty cards. Further, they may also have health-related information from fitness apps. The amount of personal information can run that broadly, and that deeply.
With information at this potential level of detail, it’s no wonder that data brokers rake in an estimated at $200 billion U.S. dollars worldwide every year.
On the legitimate side, it’s used by advertisers to create targeted ad campaigns. With information sold by data brokers, they can generate lists based on highly specific criteria, such as shopping histories, personal interests, and even political leanings as mentioned above. Likely without you being aware of it—and likely with no way to contest that information if it’s incorrect.
Other legitimate uses include using these sites for background checks. Law enforcement, reporters, and employers will use data brokers as a starting point for research because the leg work has largely been done for them. Namely, data brokers have aggregated a person’s information already, which is an otherwise time-consuming process.
If this seems a little shady, it’s still legal. As of now, the U.S. has no federal laws that regulate data brokers or require data them to remove personal information if requested. A few states, such as Nevada, Vermont, and California, have legislation in place aimed at protecting consumers. Meanwhile, the General Data Protection Regulation (GDPR) in the European Union has stricter rules about what information can be collected and what can be done with it. Still, the data broker economy thrives.
On the darker side, scammers and thieves use personal information for identity theft and fraud. With enough personal information gathered from enough sources, they can create a high-fidelity profile of their victims. One that gives them enough information to open new accounts in their name.
So, from the standpoint of both privacy and identity, cleaning up your personal information online makes a great deal of sense.
Let’s review some ways you can remove your personal information from data brokers and other sources on the internet.
The process starts with finding the sites that have your information. From there, you can request to have it removed. Yet as mentioned above, there are dozens and dozens of these sites. Knowing where to start is a challenge in of itself, as is manually making the requests once you have identified the sites that post and sell information about you.
Our Personal Data Cleanup can do the work for you. Personal Data Cleanup scans some of the riskiest data broker sites and shows you which ones are selling your personal info. It also provides guidance on how you can remove your data from those sites and can even manage the removal for you depending on your plan. It also monitors those sites, so if your info gets posted again, you can request its removal again.
As of September 2022, Google accounts for just over 92% of search engine market share worldwide. Aside from being a search engine, Google offers a myriad of other services and applications, such as Gmail and Google Maps. While Google offers plenty of tools for productivity, travel, work, and play for free, they still come at a cost—the gathering and analysis of your personal information.
You can limit the data Google associates with you by removing your name from Google search results with a removal request. This will disable anyone online from getting any results if they search your name. (Note that this will not remove your information from the original sites and sources where it’s posted.) Moreover, Google collects all your browsing data continuously. You have the option to turn on “Auto Delete” in your privacy settings to ensure that the data is deleted regularly and help limit the amount of time your sensitive data stays vulnerable.
You can also occasionally delete your cookies or use your browser in incognito mode to prevent websites from being tracked back to you. Go to your Google Chrome settings to clear your browser and cookie history.
As discussed above, data brokers can collect information from public social media profiles. You can minimize your presence on social media to the bare minimum. Make a list of the ones you use or have used in the past. If there are old accounts that you no longer use or websites that have gone by the wayside like Myspace or Tumblr, you may want to deactivate them or consider deleting them entirely.
For social media platforms that you still may use regularly, like Facebook and Instagram, consider adjusting your privacy settings to ensure that your personal information on these social media platforms is the bare minimum. For example, on Facebook you can lock your profile, while on Instagram you can stay private.
If you’ve ever published articles, written blogs, or created any content online, it might be a good time to consider taking it down if it is no longer serving a purpose. Depending on what you’ve posted, you may have shared personal details about your life. Additionally, you might be mentioned by other people in various social media posts, articles, or blogs. It is worth reaching out to these people to request them to take down posts with sensitive information.
Social media and online articles that host your personal information are often used when businesses or hackers are doing “internet scrapes” to find better ways to use your targeted information. Asking your friends or third-party sites to remove that information can help protect your privacy.
Another way you can tidy up your digital footprint online involves deleting all the unnecessary phone apps that you no longer need or use. Even when apps are not open or in use, they may be able to track personal information such as your real-time location and even your payment details if you have a paid subscription to the app.
Some apps even sell this data as it can be extremely advantageous to other companies, which they use to target certain consumer segments and profiles for advertising. Try to share as little information with apps as possible if you’re looking to minimize your online footprint, and provide them access to your photos, contacts, and location only on as-needed basis and only when the app is in use. Your phone’s app and location services settings will give you the tools to do it.
In addition to the steps above, comprehensive online protection software can keep you more private and minimize your risk of cybercrime. It can include:
So while it may seem like all this rampant collecting and selling of personal information is out of your hands, there’s plenty you can do to take control. With the steps outlined above and strong online protection software at your back, you can keep your personal information more private and secure.
The post 5 Steps to Removing Your Personal Information From the Internet appeared first on McAfee Blog.
Our personal and professional lives are becoming increasingly intertwined with the online world. Regular internet usage has made us all prone to cyber-security risks. You leave a digital footprint every time you use the internet, which is a trace of all your online activities.
When you create new accounts or subscribe to different websites, you give them explicit (or implicit, through their family of apps or subsidiary websites) access to your personal and credit card information. In other cases, websites might track basic information without your knowledge, such as your location and search history.
There is an industry of data brokers specifically dedicated to keeping track of user data, packaging it, and supplying it to tech companies who use it to run targeted ads and enhance on-platform user experience. Given the widespread use of the internet and exponential improvements in technology, data has become a valuable commodity — creating a need for the sale and purchase of user data.
This article discusses how data brokers sell your personal information and how you can minimize risk.
Data brokers are companies that aggregate user information from various sources on the internet. They collect, collate, package, and sometimes even analyze this data to create a holistic and coherent version of you online. This data is then supplied to tech companies to fuel their third-party advertising-centered business models.
Companies interested in buying data include but are not limited to:
These companies and social media platforms use your data to better understand target demographics and the content with which they interact. While the practice isn’t unethical in and of itself (personalizing user experiences and creating more convenient UIs are usually cited as the primary reasons for it), it does make your data vulnerable to malicious attacks targeted toward big-tech servers.
Most of your online activities are related. Devices like your phone, laptop, tablets, and even fitness watches are linked to each other. Moreover, you might use one email ID for various accounts and subscriptions. This online interconnectedness makes it easier for data brokers to create a cohesive user profile.
Mobile phone apps are the most common way for data brokerage firms to collect your data. You might have countless apps for various purposes, such as financial transactions, health and fitness, or social media.
A number of these apps usually fall under the umbrella of the same or subsidiary family of apps, all of which work toward collecting and supplying data to big tech platforms. Programs like Google’s AdSense make it easier for developers to monetize their apps in exchange for the user information they collect.
Data brokers also collect data points like your home address, full name, Social Security number, phone number, and date of birth. They have automated scraping tools to quickly collect relevant information from public profiles.[Text Wrapping Break]
Lastly, data brokers can gather data from other third parties that track your cookies or even place trackers or cookies on your browsers. Cookies are small data files that track your online activities when visiting different websites. They track your IP address and browsing history, which third parties can exploit. Cookies are also the reason you see personalized ads and products.
Data brokers collate your private information into one package and sell it to “people search” websites like Spokeo or TruePeopleSearch. You or a tech business can use these websites to search for people and get extensive consumer data. People search sites also contain public records like voter registration information, marriage records, and birth certificates. This data is used for consumer research and large-scale data analysis.
Next, marketing and sales firms are some of data brokers’ biggest clients. These companies purchase massive data sets from data brokers to research your data profile. They have advanced algorithms to segregate users into various consumer groups and target you specifically. Their predictive algorithms can suggest personalized ads and products to generate higher lead generation and conversation percentages for their clients.
We tend to accept the terms and conditions that various apps ask us to accept without thinking twice or reading the fine print. You probably cannot proceed without letting the app track certain data or giving your personal information. To a certain extent, we trade some of our privacy for convenience. This becomes public information, and apps and data brokers collect, track, and use our data however they please while still complying with the law.
There is no comprehensive privacy law in the U.S. on a federal level. This allows data brokers to collect personal information and condense it into marketing insights. While not all methods of gathering private data are legal, it is difficult to track the activities of data brokers online (especially on the dark web). As technology advances, there are also easier ways to harvest and exploit data.
Vermont and California have already enacted laws to regulate the data brokerage industry. In 2018, Vermont passed the country’s first data broker legislation. This requires data brokers to register annually with the Secretary of State and provide information about their data collection activities, opt-out policies, purchaser credentialing practices, and data breaches.
California has passed similar laws to make data brokering a more transparent industry. For risk mitigation of data brokerage, the Federal Trade Commission (FTC) has published reports and provided recommendations to Congress to reduce the engagement of data broker firms. Giving individuals the right to opt-out of the sale of their personal data is a step toward a more rigorous law regarding data privacy.
Some data brokers let you remove your information from their websites. There are also extensive guides available online that list the method by which you can opt-out of some of the biggest data brokering firms. For example, a guide by Griffin Boyce, the systems administrator at Harvard University’s Berkman Klein Center for Internet and Society, provides detailed information on how to opt-out of a long list of data broker companies.
Acxiom, LLC is one of the largest data brokering firms and has collected data for approximately 68% of people who have an online presence. You can opt-out of their data collection either through their website or by calling them directly.
Epsilon Data Management is another big player in the data broker industry that operates as a marketing service and marketing analytics company. You can opt-out of their website through various methods such as by email, phone, and mail. Credit rating agencies like Experian and Equifax are also notorious for collecting your data. Similarly, you can opt-out through their websites or by calling them.
McAfee is a pioneer in providing online and offline data protection to its customers. We offer numerous cybersecurity services for keeping your information private and secure.
With regard to data brokers, we enable users to do a personal data clean-up. Cleaning up your personal data online may be a difficult task, as it requires you to reach out to multiple data brokers and opt out. Instead, sign up for McAfee’s Personal Data Cleanup feature to do a convenient and thorough personal data clean-up. We will search for traces of your personal data and assist in getting it removed.

So is your smart speaker really listening in on your conversations?
That’s the crux of a popular privacy topic. Namely, are we giving up some of our privacy in exchange for the convenience of a smart speaker that does our bidding with the sound of our voice? After all, you’re using it to do everything from search for music, order online, and control the lights and temperature in your home.
What is your smart speaker really hearing—and recording?
Let’s take a look at what’s going on inside of your smart speaker, how it processes your requests, and what companies do with the recordings and transcripts of your voice.
More or less, smart speakers are listening to all the time. Each smart speaker has its own “wake word” that it listens for, like Alexa, Siri, or Google. When the device hears that wake word or thinks it hears it, it begins recording and awaits your verbal commands. Unless you have the microphone or listening feature turned off, your device indeed actively listens for that wake word all the time.
Here’s where things get interesting, though. There’s a difference between “listening” and “recording.” The act of listening is passive. Your smart speaker is waiting to hear its name. That’s it. Once it does hear its name, it begins recording for a few seconds to record your command. From there, your spoken command goes into the company’s cloud for processing by way of an encrypted connection.
There are exceptions to when your command may go to the company’s cloud for processing, like Siri on iPhones, which according to Apple, “You don’t sign in with your Apple ID to use Siri, and the audio of your requests is processed entirely on your iPhone.” Also, Google Assistant may process some requests without going to the cloud, like “When a user triggers a smart home Action that has a local fulfillment path, Assistant sends the EXECUTE intent or QUERY intent to the Google Home or Google Nest device rather than the cloud fulfillment.”
In the cases where information does go to the cloud, processing entails a few things. First, it makes sure that the wake word was heard. If it’s determined that the wake word was indeed spoken (or something close enough to it—more on that in a minute), the speaker follows through on the request or command. Depending on your settings, that activity may get stored in your account history, whether as a voice recording, transcript, or both. If the wake word was not detected, processing ends at that point.
Enter the issue of mistaken wake words. While language models and processing technologies used by smart speakers are constantly evolving, there are occasions where a smart speaker acts as if a wake word was heard when it simply wasn’t said. Several studies on the topic have been published in recent years. In the case of research from Northeastern University, it was found that dialogue from popular television shows could be interpreted as wake words that trigger recording. For example, their findings cite:
“We then looked at other shows with a similarly high dialogue density (such as Gilmore Girls and The Office) and found that they also have a high number of activations, which suggests that the number of activations is at least in part related to the density of dialogue. However, we have also noticed that if we consider just the amount of dialogue (in a number of words), Narcos is the one that triggers the most activations, even if it has the lowest dialogue density.”
Of interest is not just the volume of dialogue, but the pronunciation of the dialogue:
“We investigated the actual dialogue that produced Narcos‘ activations and we have seen that it was mostly Spanish dialogue and poorly pronounced English dialogue. This suggests that, in general, words that are not pronounced clearly may lead to more unwanted activations.”
Research such as this suggests that smart speakers at the time had room for improvement when it comes to properly detect wake words, thus leading to parts of conversation being recorded without the owner intending it. If you own a smart speaker, I wouldn’t be too surprised to hear that you’ve had some issues like that from time to time yourself.
As mentioned above, the makers of smart speakers make constant improvements to their devices and services, which may include the review of commands from users to make sure they are interpreted correctly. There are typically two types of review—machine and human. As the names suggest, a machine review is a digital analysis and human reviews entail someone listening to and evaluating a recorded command or reading and evaluating a transcript of a written command.
However, several manufacturers let you exercise some control over that. In fact, you’ll find that they post a fair share of articles about this collection and review process, along with your choices for opting in or out as you wish:
The quickest way to ensure a more private experience with your smart speaker is to disable listening—or turn it off entirely. Depending on the device, you may be able to do this with the push of a button, a voice command, or some combination of the two. This will keep the device from listening for its wake word. Likewise, this makes your smart speaker unresponsive to voice commands until you enable them again. This approach works well if you decide there are certain stretches of the day where your smart speaker doesn’t need to be on call.
Yet let’s face it, the whole idea of a smart speaker is to have it on and ready to take your requests. For those stretches where you leave it on, there’s another step you can take to shore up your privacy.
In addition to making sure you’re opted out of the review process mentioned above, you can also delete your recordings associated with your voice commands.
Managing your voice history like this gives you yet one more way you can take control of your privacy. In many ways, it’s like deleting your search history from your browser. And when you consider just how much activity and how many queries your smart speaker may see over the course of days, weeks, and months, you can imagine just how much information that captures about you and your family. Some of it is undoubtedly personal. Deleting that history can help protect your privacy in the event that information ever gets breached or somehow ends up in the hands of a bad actor.
Lastly, above and beyond these privacy tips for your smart speakers, comprehensive online protection will help you look out for your privacy overall. In the case of ours, we provide a full range of privacy and device protection, along with identity theft protection that includes $1M identity theft coverage, identity monitoring, and identity restoration assistance from recovery pros—and antivirus too, of course. Together, they can make your time spent online far more secure.
You’re the smart one in this relationship
With privacy becoming an increasingly hot topic (rightfully so!), several companies have been taking steps to make the process of managing yours easier and a more prevalent part of their digital experience.
