Houston expert shares tips for navigating cybersecurity challenges amid the holiday season

guest column

It’s a grinch's cyber-playground, and this holiday season, you’re at risk — even if you think it won’t happen to you.

The good news is you can protect yourself from scams and fraud. Just remember that cybercriminals don’t discriminate, they can prey on anyone.

These statistics may surprise you:

  • Anxiety about having a mobile device hacked differs by demographic; low-income Black women rank mobile security as their number one concern, while the general population ranks mobile security as their third largest concern, according to a recent Recon Analytics survey of more than 3,297 U.S. consumers.
  • 44 percent of millennials have been victims of online crime in the last year and 31 percent admit they share their passwords with others.
  • Romance scams resulted in the most financial losses for adults aged 60 and over
  • Younger consumers took fewest actions after being notified of a data breach affecting their identity/online accounts in Q1 2022
  • Nearly 50 percent of American gamers have experienced a cyberattack on their gaming account or device
  • 47 percent of women who live in cities say their identities and/or data has been compromised in the past 6 months due to lack of home internet protections, compared with 53 percent of city men who say the same thing, according to a recent Recon Analytics survey.

People everywhere, regardless of gender, race, income level, education, or age, deserve to feel safe online. And yet, many aren’t aware how to protect themselves, don’t make it a priority, or wait to act until they are alerted to suspicious activity.

With words like malware, phishing, spoofing, and encryption, learning to protect yourself can feel like a college-level course. But it doesn’t have to be that complicated.

Top 5 ways to guard against cyberthreats

By following five simple steps, you can start to protect your network, devices and data from many digital threats.

  1. Understand cyberattacks are real. One of the first hacks was documented in 1963 and today, nearly 60 years later, hackers are attacking phones and computers every 39 seconds. Cyberattacks continue to grow in number every year.
  2. Be proactive. Don’t wait for an attack to happen. Monitor your accounts daily so you are the first to know if suspicious activity is occurring. Check with your wireless carrier to see if they have tools to help. AT&T customers can download the free ActiveArmor mobile security app to help block spam calls and secure their personal data. And ask your internet provider about extra layers of security available to you at home. AT&T Fiber customers can access AT&T ActiveArmor internet security features at no additional cost to them.
  3. Step up your mobile security. Mobile devices now account for more than 60 percent of digital fraud. Mobile banking, online shopping, streaming videos and storing documents make our phones a central location for sensitive information. Your wireless carrier may be able to help. AT&T offers advanced security like Public Wi-Fi Protection, Identity Monitoring and Safe Browsing for no extra charge with some of our plans. Check with your carrier to make sure they’re doing what they can to keep you safe.
  4. Protect your passwords. We all know it’s necessary, but not all of us take steps to do it. 68 percent of people admit to using the same password across multiple logins. Using a strong password that differs from site-to-site will help decrease your chances of being hacked. If you struggle with passwords, consider getting a password manager.
  5. Report suspicious text messages. As mobile operators have more success blocking illegal robocalls, scammers have turned to text messages. But now it’s easier than ever to report spam texts to help block and control them. The latest iOS and Android operating systems have a simple reporting feature in their Apple and Google messaging apps.

Houston expert: New location-based tech is en route to saving lives

guest column

“911, what’s your location?”

It’s a phrase we’ve heard hundreds of times on TV shows and movies. In real life though, have you ever considered the possibility that this question — one that can mean the difference between life and death — may be hard for the caller to answer? In an emergency, you may not be able to speak. If you’re in a car accident, you may not know where you are. In a disaster, your surroundings may be confusing.

That’s where a new location-based routing feature we call “Locate Before Route” comes in. This summer, AT&T, in collaboration with Intrado, rolled out a first-of-its-kind 911 upgrade across the country that will make it easier for emergency personnel to find and send help to wireless callers.

Roughly 80 percent of 911 calls today are made from cell phones. Before location-based routing, a call would ping a cell phone tower and connect to the dispatch center closest to that tower. But here’s the thing: that cell tower could be up to 10 miles away. Imagine needing help in Deer Park but the dispatcher thinking you may be in Baytown. You could even be in a different county, making it difficult for dispatchers to pinpoint exactly where the call is calling from.

Here’s how it works:

Instead of pinging the closest cell tower, the GPS in your phone connects with the closest 911 dispatch center, meaning emergency operators can locate you within about 55 yards of your position. That’s about half a football field.

This kind of accuracy means public safety can respond faster, especially in situations when a 911 wireless caller doesn’t know or can’t disclose their location.

AT&T is the first wireless carrier to launch location-based routing for all 911 call centers nationwide, whether they’re operating on older technology or NextGen 911. The best part: AT&T customers across the country automatically have access to this service – no action is necessary.

AT&T’s commitment to public safety is longstanding. Following the events of September 11th, we worked to create FirstNet, – the only nationwide communications platform dedicated to public safety and first responders. With nationwide location-based 911 call routing, we are providing our customers with the quickest, most accurate way to call emergency personnel for help when it’s most needed.

Houston expert: Prime times for cyber-attacks and how to stay protected

guest columns

October is cybersecurity awareness month. The topic might sound overwhelming, and it certainly can be, but there are a few easy ways we can educate and protect ourselves and our loved ones.

Be mindful of timing

Cyber actors target certain times to strike. Experts warn that holiday weekends like Thanksgiving are some of the most prolific times for scammers, who never take a vacation. They can defraud and monetize their actions with little effort.

Why?

During holiday weekends, many people make plans and shop -- online or on a mobile device -- and document their activities on social media. Holidays also come with an elevated amount of email and financial activity, all conveniently while people are "checked out" or traveling. Inboxes become overloaded with holiday messaging and deals.

Attacking someone's account can go unnoticed longer if that person is away from their computer. Or a hacker might execute a well-timed phishing attack for a Friday afternoon, right before someone goes on vacation.

Imagine planning a getaway to Galveston and an email arrives about your hotel confirmation or coupons to attractions at Pleasure Pier. Something like that might be ignored most of the time, but when you're amped up and packing your bags for vacation, it could be enticing.

Protect yourself 

Now that you have some context of when these attempts could happen, here are a few steps you can take now to protect yourself:


Don't click on suspicious links

If you don't know the sender of a text or email, don't open links they contain. Viruses and malware can start pulling information from your personal accounts. Some may look like they are coming from a friend or coworker. Or if the sender looks like a company you do business with and tells you to click a link or call a number, don't call, or click. Instead, call the customer service number on your regular bill and ask if the message is legitimate. In the case above, it may be an attempt to get personal information or scam you.

Remember, government agencies, banks, and other legitimate companies will never ask for personal or financial information, like usernames, passwords, PINs, or credit or debit card numbers by unsolicited text message. If someone calls asking for payment or personal information, tell them you'll call them back and go to the official website and call the real number to see if there is an actual issue.

Block spam calls

AT&T blocks or labels about 1 billion robocalls each month, and our patented, automated scanning helps block spam texts. So, while it may seem like your phone is ringing non-stop with spam calls and even spam texts, imagine how many are blocked. To reduce the number of annoying calls you get each day, find a good calling blocking app. The free AT&T Call ProtectSM app includes spam and automatic fraud call blocking, warns you of incoming nuisance calls, lets you customize your robocall protection and even create your own personal block list.

Become Cyber Aware

As hackers and their scams become more sophisticated, it can seem daunting to protect your accounts, devices and information. Don't despair. Learn how to outsmart the bad guys on att.com/cyberaware. You'll find timely news and information, a quiz to assess your personal risk, and valuable advice for real-life situations, such as what to do if you clicked, answered, or opened a potential scam.

With holiday season around the corner, keep in mind that you aren't the only one preparing for time off or a long weekend. Hackers are getting ready, so you need to be ready, too.

Expert: How to ensure your tech is ready for a hurricane in Houston

Guest column

Houstonians are no strangers to hurricanes. We've already seen some activity this summer, and we still have a few months to go. Although we can't prevent every negative situation when it comes to weather, AT&T has picked up a few tried and true tips that can help you stay safe prepared during this hurricane season.

Tips to plan ahead:

  • Save your smartphone's battery life. In case of a power outage, extend your device's battery life by putting it in power-save mode, turning off Bluetooth and Wi-Fi, deleting apps, or putting your phone in Airplane Mode. This may prevent you from using certain features but will ultimately save battery power.
  • Keep your mobile devices charged. Be sure to have another way to charge your smartphone if the power goes out. One option might be using your car's USB port or a USB car charger.
  • Keep your mobile devices dry. Mobile phones can be a critical lifeline during a storm. To protect yours, store it in a water-resistant case, floating waterproof case, or plastic bag. A car charger or back-up battery pack can come in handy. If you have multiple devices to keep charged, consider a multi-port back-up battery pack.
  • Back up important information and protect vital documents. Consistently back up insurance papers, medical information and the like to the Cloud or your computer. With cloud storage, you can access your data from any connected device.
  • Have a family communications plan. Choose someone out of the area as a central contact in case your family is separated. Most importantly, practice your emergency plan in advance.
  • Store emergency contacts in your mobile phone. Numbers should include the police department, fire station, hospital, and family members.
  • Forward your home number to your mobile number in the event of an evacuation. Because call forwarding is based out of the telephone central office, you will get calls from your landline phone even if your local telephone service is down.
  • Track the storm on your mobile device. If you lose power at your home during a storm, you can use your mobile device to access local weather reports.

Likewise, we take a series of steps to ensure our Houston area network is ready to withstand the storm season each year.

Preparing our network in Houston:

When we know a storm is coming, we immediately assess what is needed to prepare our network. Some of those measures include:

  • Engaging Network Operations Center to monitor the network and partner with local personnel for recovery efforts.
  • Maintaining backup generators at cell sites and switching facilities in case of power loss.
  • Staging portable generators at strategic locations for deployment after an event.
  • Working with State and Federal Emergency Operations Centers to ensure first responders have the mobile connectivity they need before, during and after an event.

Keeping first responders connected:

Communication is critical to rescue and recovery efforts. That's why we were selected by the First Responder Network Authority (FirstNet Authority) – an independent agency within the federal government – to deliver FirstNet® to first responders and the extended public safety community. FirstNet is the only nationwide network built with and for America's first responders. In the Houston area, agencies using FirstNet include Law Enforcement, Fire, EMS, and Emergency Management, among others. FirstNet is used in day-to-day operations and during emergency response, including hurricane preparedness and response. In addition, organizations and agencies that could be called on to help support public safety also use FirstNet. These include healthcare, public works, essential government services, school security, utilities, energy, and transportation that operate in support of primary public safety entities and are critical to the response efforts. Together, these agencies utilize the FirstNet network for broadband connectivity for voice and data to prepare for and respond to hurricane events. FirstNet provides the connectivity they need with:

  • Priority & Preemption: In emergencies and disasters, commercial networks can quickly become congested. That's why FirstNet is the only nationwide network that gives first responders always-on priority and preemption. It puts them at the front of the "communications line."
  • Greater Command & Control: Public safety agencies have access to a fleet of more than 100 dedicated mobile cell sites that link to FirstNet via satellite and do not rely on commercial power availability. New this storm season, there's a giant addition to the FirstNet disaster response arsenal: FirstNet One – an approximately 55-foot aerostat, more commonly known as a blimp. And, to give first responders greater command and control of their network, the FirstNet Response Operations Program aligns with the National Incident Management System to better guide the deployment of these assets.
  • Enhanced Coverage and Capacity: We've also deployed FirstNet Band 14 spectrum. Band 14 is nationwide, high-quality spectrum set aside by the U.S. government specifically for FirstNet. We refer to it as public safety's VIP lane- during an emergency, this band can be cleared and locked just for FirstNet subscribers.

Recovery and relief:

During those unfortunate times when recovery response is needed, our Natural Disaster Recovery program and FirstNet Response Operations Group have technology and equipment to help with relief efforts such as:

  • Mobile cell sites and mobile command centers, like Cell on Wheels (COWs) and Cell on Light Trucks (COLTs)
  • Emergency Communications Vehicles (ECVs)
  • Flying Cell on Wings (Flying COWs)
  • Drones
  • A self-sufficient base camp: complete with sleeping tents, bathrooms, kitchen, laundry facilities, an on-site nurse, and meals ready to eat (MREs)
  • Hazmat equipment and supplies
  • Technology and support trailers to provide infrastructure support and mobile heating ventilation and air conditioning
  • Internal and external resources for initial assessment and recovery efforts

Together, let's have a smart and safe hurricane season.

How 5G and smart cities technology are transforming the city of Houston

guest column

A firefighter stands in front of a burning building in Sunnyside. A drone buzzes overhead to capture video of the parts of the structure they can't get eyes on. Infrared technology helps them see "through" the building to where people may be trapped. Robotic cameras are sent in to provide live video from inside, while a tablet shows blinking dots in real time of where the other firefighters are as they move through the different floors of the building.

An injured civilian is pulled out of the flames. A drone delivers potentially life-saving medication while the paramedics assess the damage. The victim's medical records are shared instantaneously with the hospital, and paramedics are connected live to the emergency room while in-transit. As they make their way to the hospital, traffic signals are a step ahead – lights are green at just the right time on Reed and Almeda, clearing the way for an expedited ride and keeping traffic safe for all until the ambulance arrives at the hospital where medical personnel already know what's needed and are ready to jump into action.

It may sound like something out of a science fiction novel, but much of this is already happening. And the parts that aren't commonplace yet may be a reality very soon. We've heard about smart cities technology for some time, and different cities will adopt technology at different paces, but the pieces are finally coming into place.

What has changed to bring this futuristic world into the present? 5G.

There's a lot of noise out there about 5G, and from a consumer standpoint most of the chatter is about speed. Yes, 5G is faster, but here at AT&T we're quick to point out that speed is only the beginning: The capacity and responsiveness of 5G technology is what makes it revolutionary for use cases like these.

According to analyst research reported by CIO Magazine, 4G technology allows around 2,000 devices all connecting at the same time in a 1-kilometer area (0.386 miles). It's the reason that you might have trouble getting a call or a text to go through when you're at a crowded stadium. The network is ready and willing, but too much demand on one location slows things down.

Think about all the connections necessary in the above scenario. The drones, each firefighter, the robotic camera, the tablets, the ambulance and its equipment, sensors in the building, the hospital and all the people waiting there, the traffic signals… the list goes on. Well, 5G technology enables something called Massive IoT and can mean as many as 1 million devices can be connected in that same kilometer range, according to analyst research reported by CIO Magazine. That's game changing. AT&T has already installed its fastest 5G+ technology at the Toyota Center. Hopefully the next time you're there you'll feel the difference for yourself.

But having all those things talk to each other only makes a real difference if the connection is uninterrupted and in as real time as possible. 5G gives us that, as well. Ultra-low latency reduces response times to milliseconds. And when you add near-zero lag time to all those connections, the future becomes the present.

At AT&T we're passionate about public safety. That's why we created FirstNet, the first dedicated network exclusively for first responders, which ensures that the lines of communication stay open when they're needed the most. Harris Health System and Harris County Juvenile Probation are among the agencies already using the network. Going forward, FirstNet could be a crucial part of smart cities technology as capabilities increase.

There are plenty of use cases that 5G will continue to enhance: Think live feeds of police body cameras and locations when in a pursuit, helping increase efficiency and accountability. Think about the first responders themselves. Did you know that heart attack is the leading cause of death among firefighters? Vital signs could be monitored allowing alerts to a fire company of an elevated heart rate in their crew, potentially saving the life of a lifesaver.

5G could be the catalyst that leads to the true adoption of autonomous cars, as millions of sensors allow not only vehicle to vehicle communication, but could also integrate pedestrian traffic, making it safer for everyone as we move towards assisted and eventually self-driving vehicles.

Utility grid sensors could allow power companies to plan more effectively for use, pinpoint outages quickly, and use AI to divert energy and heal itself.

And we all know about Houston traffic. What if there's a world coming soon where we could alleviate just 20 percent of the congestion through smart city technology? In an hour commute, you just got 12 minutes back to spend with your family.

The technology is already getting smarter. The cities won't be far behind.

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
