• The Tech University Health Sciences Center in Texas and El Paso confirmed suffering a cyberattack
• Data on 1.4 million people were exfiltrated in the attack
• A threat actor named Interlock claimed responsibility for the attack

Another major US hospital has suffered a cyberattack recently, and as a result, lost sensitive data on more than a million patients.

In an announcement published on its website, the Texas Tech University Health Sciences Center, and Texas Tech University Health Sciences Center El Paso (HSCs), confirmed suffering a “temporary disruption to some computer systems and applications.”

Subsequent investigation confirmed that the disruption was the result of a ransomware attack, in which “certain files and folders” were removed from the HSCs’ network. The attack allegedly happened on September 17, and was discovered more than a week later, on September 29.

Another hospital attacked

In the notice, it did not say how many people were affected, or who the attackers were, but in a separate filing with the U.S. Department of Health and Human Services Office for Civil Rights, it said the number was 1,465,000.

HSCs concluded that crooks stole sensitive data such as people’s names, date of birth, address, Social Security number, driver’s license number, government-issued identification number, financial account information, health insurance information and medical information, including medical records numbers, billing/claims data and diagnosis and treatment information.

The threat actor behind this attack is called Interlock, and appears to be a relatively new ransomware operation, which targets high-profile organizations and demands hundreds of thousands of dollars in ransom. The group recently added HSCs’ data to its leak website, where it showcased 2.1 million files, totaling 2.6 terabytes.

To combat the attack, HSCs are currently reviewing existing security policies and procedures, and are implementing additional safeguards to enhance system protection and monitoring, it was said in the announcement. Out of an abundance of caution, HSCs added, affected individuals are offered complimentary credit monitoring services, free of charge.

If you’ve been following the news from 12 Days of OpenAI, you’ll know that OpenAI has released ChatGPT search to the world as part of its Christmas-themed launch extravaganza.

This means that everybody with a ChatGPT account (you need to be logged in to use it) now gets access to ChatGPT search. OpenAI has also added ChatGPT search to Advanced Voice mode, and made it faster and better on mobile.

Previously, ChatGPT search was only available to ChatGPT Plus subscribers and people who had signed up to the waiting list. Now it’s available to everyone. All you need to do to use it is go to ChatGPT.com or open the ChatGPT app on your phone, tap or click on the little world icon in the ChatGPT prompt window and a blue 'Search' label appears, to indicate that whatever you type in next will become a web search, not a typical chatbot interaction.

Just what is an AI search engine anyway?

An AI search engine differs from a conventional search engine, like Google, in a few key ways. First, you can use natural, conversational language instead of search terms. We’re all so conditioned to using Google these days that we default to a search term-based language when we use it, and not doing that can take a bit of getting used to.

So, for example, you could start off by asking “what are the best laptops around right now?”, in the same way you would in a conversation, and then when you get the results you can follow up with “I want one for gaming” and ChatGPT will know what you’re talking about, and give you some more results.

Second, there are no adverts. Some people enjoy sponsored content links in searches, since it quite often gives you a link to exactly what you’re looking for, but you won’t find any in ChatGPT search. It very much reminds me of the early, simpler days of Google.

Perplexity vs ChatGPT

The concept of an AI search engine isn’t that new, in fact there’s another contender in the field that has been doing it for longer than ChatGPT has, and that’s Perplexity. Perplexity is perhaps the original AI search engine. From the start it was designed to search the web and find results, then give you an accessible, and conversational answer.

Now we have two AI search engines going head to head, so it’s natural to want to compare them. I picked a range of subjects to ask both about, and I was quite shocked by the results.

I started with: “I love pizza, are there any good pizza restaurants near me?”

I was a bit surprised when both search engines initially recommended restaurants that were in my nearest city, rather than local to me; however, after I told them exactly where I lived I got better results – and very similar results – from both. In fact they recommended exactly the same restaurants. What really surprised me was the amount of detail I got from Perplexity – a lot more than I got with ChatGPT search.

On web or mobile, ChatGPT’s search results appear as quite a boring text-based list. You get a simple description of each restaurant and a link to its website; that's it. In contrast Perplexity gives you a lot more information, and it's a lot more interesting to look, at since each result is broken down into subheadings – in this case Address, Highlights, Features and Rating. There are links to the websites, plus to the reviews online. You can choose to show all the sources in a list on the right-hand side of the page, where you also get a selection of images of the subject you're searching for.

It was the same when I tried other searches like, “Who will be the next James Bond?”, or “What laptop should I buy for Christmas?”. The ChatGPT search results were sparse and lacking in detail, while the Perplexity results had many more links to sources, and just felt more fleshed out and informed.

My overall recommendation? Perplexity is better. Both search engines produced similar results in terms of the sources found, but Perplexity presents the information in a better way, and with more detail that makes it easy to progress your search to the next thing you’re likely to be looking for, like a review.

Sorry, ChatGPT search – you’re good, but you’re still new to this game, and Perplexity has the edge right now.

• Many home devices harvest and share more data than is necessary
• US and UK watchdogs are setting out rules to protect device owners
• Researching appliances and using them offline can help keep data secure

Last month, consumer body Which? revealed that many popular smart home devices, including air fryers, may be capturing unnecessary data and sharing it with third parties - facts that you could easily miss when choosing and setting up a new appliance. Now, consumer rights watchdogs in the US and the UK have outlined plans to force companies to be more transparent about what information they keep, and how it's used.

As Gizmodo explains, the Information Commissioner’s Office (ICO) in the UK is planning to issue new guidance to companies early next year specifically related to smart home tech and user privacy. According to the ICO, this "will outline clear expectations for what they need to do to comply with data protection laws and, in turn, protect people using smart products."

Meanwhile, in the US, the Consumer Financial Protection Bureau (CFPB) has proposed a new rule that would limit brokers' ability to sell personal information that might been acquired in data breaches. Under the proposed rule, these brokers would be treated like credit bureaus and background check companies, and held to the same standards.

How to keep yourself (and your data) safe

This is promising news, but how can you determine whether a smart home device is safe to use right now? Reading the privacy policy thoroughly is the obvious first step, but some can be prohibitively lengthy.

Home tech companion apps come with their own privacy policies too, but remember that just because a device has a companion app, or can be connected to Wi-Fi or Bluetooth, it's often not necessary to use its key functions. For example, my electric toothbrush has an app that awards you badges for brushing your teeth for two minutes twice a day, but it works perfectly fine without that. Similarly some of the best air fryers have an app that lets you adjust the temperature remotely and provides recipe ideas, but isn't mandatory for cooking your fries.

If your device does need to be online, The Mozilla Foundation's Privacy Not Included report is a good starting point. The foundation's researchers have pored over the privacy policies for dozens of products, including home security cameras, smart thermostats, and robot vacuum cleaners, to find out exactly how much data they gather, what their default privacy settings are, who your data may be shared with, and what could happen if the company suffers a data leak.

For example, the Garmin Index S2 smart scale collects a lot of personal information (gathering biometrics is its job, after all), but the company's privacy policy is transparent, neither shares nor sells your data, and has acted on previous advice from Mozilla to make it clearer that all users have the right to delete their data, regardless of where they live.

Ecobee (maker of one of the Ecobee SmartThermostat) also earned praise for its SmartCamera home security device, which sends encrypted video footage directly to your phone without being recorded. If you do choose to save any photos or clips, the company says they will be deleted from its servers automatically when you uninstall the app.

Make sure that any connected devices are set to receive automatic security updates so any vulnerabilities discovered are patched as soon as possible.

What's the worst that could happen?

If your data isn't properly protected, the results can be devastating. Just last week, personal data from matchmaking site Senior Dating was discovered on data leak site Have I Been Pwned, exposing sensitive data relating to over 700,000 people, including photos, email addresses, and physical locations.

In October, a Brazilian driving school was found to have exposed the sensitive data of 400,000 people by leaving a database unsecured. Photos, full names, addresses, and government ID numbers were all left unsecured, putting people at serious risk of identity theft and harassment.
