Pagers and walkie-talkies over cellphones – a security expert explains why Hezbollah went low-tech for communications
The synchronized explosion of pagers and walkie-talkies in Lebanon in 2024 targeted Hezbollah, demonstrating the vulnerabilities and tracking capabilities of communication devices.
Richard Forno, University of Maryland, Baltimore County
Electronic pagers across Lebanon exploded simultaneously on Sept. 17, 2024, killing 12 and wounding more than 2,700. The following day, another wave of explosions in the country came from detonating walkie-talkies. The attacks appeared to target members of the militant group Hezbollah.
The pagers attack involved explosives planted in the communications devices by Israeli operatives, according to U.S. officials cited by The New York Times. Hezbollah had recently ordered a shipment of pagers, according to the report.
Secretly attacking the supply chain is not a new technique in intelligence and military operations. For example, the U.S. National Security Agency intercepted computer hardware bound for overseas customers, inserted malware or other surveillance tools and then repackaged them for delivery to certain foreign buyers, a 2010 NSA internal document showed. This differs from accessing a specific person’s device, such as when Israel’s Shin Bet secretly inserted explosives into a cellphone to remotely kill a Hamas bombmaker in 1996.
Hezbollah, a longtime adversary of Israel, had increased its use of pagers in the wake of the Hamas attack on Israel on Oct. 7, 2023. By shifting to relatively low-tech communication devices, including pagers and walkie-talkies, Hezbollah apparently sought an advantage against Israel’s well-known sophistication in tracking targets through their phones.
Cellphones: The ultimate tracker
As a former cybersecurity professional and current security researcher, I view cellular devices as the ultimate tracking tool for both government and commercial entities – in addition to users, criminals and the mobile phone provider itself. As a result, mobile phone tracking has contributed to the fight against terrorism, located missing people and helped solve crimes.
Conversely, mobile phone tracking makes it easy for anyone to record a person’s most intimate movements. This can be done for legitimate purposes such as parents tracking children’s movements, helping you find your car in a parking lot, and commercial advertising, or nefarious ends such as remotely spying on a lover suspected of cheating or tracking political activists and journalists. Even the U.S. military remains concerned with how its soldiers might be tracked by their phones.
Mobile device tracking is conducted in several ways. First, there is the network location data generated by the phone as it moves past local cell towers or Stingray devices, which law enforcement agencies use to mimic cell towers. Then there are the features built into the phone’s operating system or enabled by downloaded apps that may lead to highly detailed user tracking, which users unwittingly agree to by ignoring the software’s privacy policy or terms of service.
This collected data is sometimes sold to governments or other companies for additional data mining and user profiling. And modern smartphones also have built-in Bluetooth, Wi-Fi and GPS capabilities that can help with locating and tracking user movements around the world, both from the ground and via satellites. https://www.youtube.com/embed/CxC1KCoGbIM?wmode=transparent&start=0 Your phone contains many sensors that make it useful – and easy to track.
Mobile devices can be tracked in real time or close to it. Common technical methods include traditional radio direction-finding techniques, using intelligence satellites or drones, deploying “man in the middle” tools like Stingrays to impersonate cellular towers to intercept and isolate device traffic, or installing malware such as Pegasus, made by Israeli cyberarms company NSO to report a device’s location.
Nontechnical and slower techniques of user tracking include potentially identifying general user locations from their internet activity. This can be done from website logs or the metadata contained in content posted to social media, or contracting with data brokers to receive any collected location data from the apps that a user might install on their device.
Indeed, because of these vulnerabilities, the leader of Hezbollah earlier this year advised his members to avoid using cellular phones in their activities, noting that Israel’s “surveillance devices are in your pockets. If you are looking for the Israeli agent, look at the phone in your hands and those of your wives and children.”
Researchers have shown how these features, often intended for the user’s convenience, can be used by governments, companies and criminals to track people in their daily lives and even predict movements. Many people still aren’t aware of how much their mobile devices disclose about them.
Pagers, however, unlike mobile phones, can be harder to track depending on whether they support two-way communication.
Why go low-tech
A pager that only receives messages does not provide a signal that can facilitate tracking its owner. Therefore, Hezbollah’s use of pagers likely made it more challenging to track their operatives – thus motivating Israeli intelligence services’ purported attack on the supply chain of Hezbollah’s pagers.
Using low-tech tactics and personal couriers while avoiding the use of mobile phones and digital tools also made it difficult for the technologically superior Western intelligence agencies to locate Osama bin Laden for years after the 9/11 attacks.
In general, I believe the adversary in an asymmetric conflict using low-tech techniques, tactics and technology will almost always be able to operate successfully against a more powerful and well-funded opponent.
A well-documented demonstration of this asymmetry in action was the U.S. military’s Millennium Challenge war game in 2002. Among other things, the insurgent Red forces, led by Marine General Paul van Riper, used low-tech tactics including motorcycle couriers instead of cellphones to evade the Blue forces’ high-tech surveillance. In the initial run of the exercise, the Red team won the contest in 24 hours, forcing exercise planners to controversially reset and update the scenario to ensure a Blue team victory.
Lessons for everyone
The preference for terrorist organizations like Hezbollah and al-Qaida to avoid using smartphones is a reminder for everyone that you can be, and likely are being tracked in various ways and for various purposes.
Israel’s purported response to Hezbollah’s actions also holds a lesson for everyone. From a cybersecurity perspective, it shows that any device in your life can be tampered with by an adversary at points along the supply chain – long before you even receive it.

Untreated sewage and fertilizer runoff threaten the Florida manatee’s main food source, contributing to malnutrition
Aarin-Conrad Allen, Florida International University
The gentle, slow-moving Florida manatee has no natural predators.
And yet, these charismatic mammals face numerous threats.
Manatees are struck by vessels in busy waterways across the state, and a majority bear scars from these collisions.
Harmful algal blooms – characterized by the rapid growth of algae that degrades water quality – can impair their nervous systems.
With less blubber, or fat, compared with other marine mammals like whales, dolphins, seals and sea lions, manatees are vulnerable to cold-stress syndrome during winter months.
And they can ingest or get entangled in marine debris like derelict fishing gear and drown or be crushed by floodgate and water control structures.
I am a doctoral candidate in marine biology at Florida International University’s Institute of Environment. Over the past 15 years, I have gained extensive experience working with marine mammals, particularly manatees.
Recently, my colleagues at the United States Geological Survey, Florida Department of Environmental Protection and I documented a change in the dietary pattern of manatees. We found that manatees are eating less seagrass – traditionally their primary food source – and more algae than in decades past. This change occurred along Florida’s Atlantic coast during a period of extensive seagrass decline.
We believe this represents an emerging threat to the species’ survival.
Protected species
Manatees were listed as an endangered species under the Endangered Species Act of 1973. By the early 1990s, the manatee population in Florida had dwindled to less than 1,300.
Researchers believe that federal protection, along with additional state measures such as slow-speed zones and no-entry refuges, has contributed to the growth of the manatee population in Florida.
In 2017, manatees were reclassified from endangered to threatened. Surveyors counted 5,733 individual manatees during a statewide aerial survey conducted in 2019.
Florida manatees average 9-12 feet (2.7-3.7 meters) in length and typically weigh about 1,000 pounds (450 kilograms), but they can grow as large as 3,500 pounds (1,600 kilograms). As the largest fully aquatic herbivore, they consume 5% to 10% of their body weight in vegetation each day.
While manatees eat a broad diet of over 60 different plants, they most commonly feed on species of seagrass. Seagrasses are marine plants that, like land plants, have leaves, flowers, roots and seeds, and make their food through photosynthesis.
So what happens when these seagrasses are no longer available?
A changing estuary
The Indian River Lagoon is an estuary along Florida’s east coast that covers roughly 350 square miles (560 square kilometers) between the mainland and barrier islands, from Ponce Inlet to Jupiter Inlet.
It is a critical habitat for manatees, which feed on native seagrass meadows in the lagoon during their seasonal migrations.
Seagrasses are vital to the health of marine ecosystems. They are a habitat for juvenile fish and other marine organisms, provide food for aquatic herbivores, reduce carbon in the atmosphere and improve water quality. They also protect coastal habitats by stabilizing sediments and reducing wave energy that can erode shorelines and damage coastal infrastructure, especially during hurricanes.
For more than a decade, the Indian River Lagoon has experienced extensive loss of seagrass meadows, due to a series of algae blooms associated with nutrient runoff and degraded water quality from septic overflow leaching into the environment.
When untreated sewage and fertilizers flow into the estuary, they add nitrogen, phosphorus and other nutrients that drive excessive algal growth. These harmful algal blooms deplete oxygen levels and block sunlight, which seagrass needs for photosynthesis.
Between 2011 and 2019, over 50% of all seagrass in the lagoon was lost. This led to an increase in macroalgae and even led to a change in the animal communities that live in the lagoon. For example, among finfish, sheepshead populations declined, while seabream numbers increased. Invertebrate communities were also affected, with bryozoans colonizing areas previously dominated by barnacles.
Manatees along the Atlantic coast have suffered two unusual mortality events since the seagrass decline, including one that is ongoing. Researchers attribute the increase in manatee deaths to malnutrition due to a shortage of seagrasses in the Indian River Lagoon.
A shift in manatees’ diet
In our study, we examined 193 manatee stomach samples collected from carcasses recovered from the Indian River Lagoon during two time periods – one before and one after the onset of the seagrass loss in 2011.
We compared stomach sample contents from carcasses collected between 1977 and 1989 with samples collected between 2013 and 2015.
Our findings indicate that manatees consumed 45% less seagrass and 74% more algae after the seagrass decline.
Recently, in a study supported by FIU’s Center for Aquatic Chemistry and Environment, I investigated differences in the nutritional composition – like protein, fat, carbohydrate and fiber – of items identified in manatee stomach samples. My preliminary results show notable differences in the nutritional composition of seagrass and algae.
Marine mammals are particularly vulnerable to dietary shifts due to their large size and high energy demands. Such changes can worsen their physical health and increase the likelihood of starvation.
Depleted oxygen levels are having a similar impact on aquatic vegetation and seagrass meadows in other regions of Florida, like Biscayne Bay and the Caloosahatchee River and Estuary. This suggests that the ecological challenges seen in the Indian River Lagoon could become more widespread.
What is the solution?
Remediation efforts within the lagoon have incorporated the restoration of seagrass through aquaculture and replanting strategies, similar to efforts to restore coral reefs.
While the lagoon’s seagrass has recently shown signs of regrowth, the rehabilitation of the ecosystem must begin with improving and maintaining water quality.
Counties along the lagoon have enacted fertilizer bans that aim to reduce the levels of nitrogen and phosphorus in the water that drive algal blooms.
New research, however, indicates that these restrictions alone will not fix the problem, as residential septic systems are the primary source of nutrient pollution in the lagoon.
Furthermore, many of the factors contributing to harmful algal blooms are intensified by global warming and changing climate, which could accelerate the decline of seagrass in Florida and elsewhere.
Given the multiple, synergistic threats facing manatees, I believe that improving water quality, protecting their food sources, and further research – coupled with community outreach and education – are critical to ensure the long-term survival of this iconic Florida species.

Republican lawmakers will reshape tax policy in 2025 — a tax expert explains what to expect
Jim Franklin, Western Governors University School of Business
Although coverage of the 2024 election was dominated by the economy, taxes didn’t get much attention in the run-up to the vote. That’s a bit of a surprise, since 2025 will be a major year for America’s tax system – in fact, the fate of the most significant tax reform in three decades hangs in the balance.
That would be the Tax Cuts and Jobs Act, which Congress passed during President-elect Donald Trump’s first term in office in 2017. If lawmakers don’t take action, the whole package is set to expire at the end of next year. Western Governors University School of Business tax expert Jim Franklin explains what might be in store for the act, and for taxpayers.
What do the election results mean for Republicans’ ability to advance their tax agenda?
We know there will be a Republican president, and it appears the Republican Party will have the majority in both chambers of Congress. That means Republicans will be able to pass a tax bill along party lines, similar to how Democrats passed the Inflation Reduction Act using budget reconciliation.
This would allow Republicans to pass key policies with a simple majority. The Republican majority is narrow, so it will be interesting to see how the leaders unify their constituent groups.
Republicans have traditionally supported lower tax rates for businesses and individuals, as well as tax incentives to help boost economic activity.
What’s next for the Tax Cuts and Jobs Act?
Currently, the act is set to expire at the end of 2025, but Trump and Republicans favor renewing many of its provisions.
The nonpartisan Congressional Budget Office in May 2024 estimated that extending the act would cost the government US$4.6 trillion, and there’s a split within the party, with one bloc of congressional Republicans calling for a full extension and another asking for the balancing of tax policy and annual federal deficits.
Republicans are likely to fight to keep key components in place, including the higher standard deduction, reduced corporate tax rates, individual rate cuts and an increased estate tax exemption.
There’s even talk of lowering the corporate tax rate further, possibly to 15% for domestic production, which would be a significant move.
What other tax measures are Republicans considering?
Trump mentioned a variety of tax relief ideas on the campaign trail, including exempting tips, Social Security benefits and overtime pay from income taxes, and creating an itemized deduction for auto loan interest.
However, Republicans aren’t entirely unified on tax policy. Some deficit hawks are concerned about revenue losses, so there could be internal pushback on all these points. The real question is whether there will be enough opposition within the party to alter or block certain proposals.
But I expect many parts of the act to be renewed, and we may see some additions. For example, there’s been a lot of pressure around increasing the state and local tax deduction cap, also known as SALT, which has bipartisan support in states with higher state income taxes like New York, California and Illinois. It will be interesting to see if that gains any traction. There’s a lot of pressure among representatives, both Republicans and Democrats, to gain some relief in that area.
Where will they find revenue?
Good question. Observers are indicating that Republicans are likely to look at cutting green energy subsidies from the 2022 Inflation Reduction Act. These could be eliminated to help balance out the cost of their new tax proposals.
Another area to watch is tariffs. There’s talk of raising tariffs on Chinese goods — potentially up to 60% — and even imposing a universal tariff on all U.S. imports at a 20% rate. It will be interesting to see how this plays out. Will it be more targeted? For example, will there be continued tariffs on select imports such as automotive imports from China to protect the U.S. electric vehicle market?
What will you be watching between now and Tax Day?
One factor will be Trump’s cabinet appointments. Whoever he nominates for Treasury secretary, for instance, could have a big influence. They can help shape what the tax bill looks like. Another key factor will be who ends up on the congressional tax committees. The composition of key committees will affect the direction of policy and the specific details.
What do you think will happen with tariffs?
Tariffs are unpredictable: They could be applied broadly, or more selectively. It could be similar to the way that Trump and his first administration placed some tariffs on steel, aluminum and solar panels. Interestingly, many of the tariffs were retained by the Biden administration.
Blanket tariffs could slow down the economy, so there is always a risk. Tariffs impact inflation because they affect the cost of imported goods, which would likely reduce consumers’ purchasing power. Domestic political pressure will play a role, as higher tariffs could raise prices on many goods that are imported, including essential products like medications.
Do you have advice for people struggling to keep up with the latest tax news?
Observers often take every policy suggestion on the campaign trail literally — exempting tips, Social Security benefits, overtime pay, etc. — as if all these proposals will pass exactly as stated. But the details matter, and policies are rarely implemented without adjustments. So it’s wise to read beyond the headlines.
