How Do You Test Walkie-Talkies After a Cyberattack.
Picture This: Communication in Crisis
Imagine this for a second: You’re in the midst of an emergency—maybe you’re a first responder, part of an event security team, or coordinating a project at a remote site. Everyone depends on walkie-talkies to relay vital instructions. Suddenly, the chatter goes dead, voices are garbled, or, even scarier, you hear someone on your channel who clearly shouldn’t be there. Turns out, you’ve just become the latest victim of a cyberattack on your communication system.
Now, if you’re like most people, you probably think of walkie-talkies as “offline” gadgets—immune to the digital dangers that plague computers and smartphones. But here’s the twist: modern walkie-talkies, especially digital models, aren’t as invincible as you’d hope. In fact, their growing list of features (think firmware updates, encryption, and even Wi-Fi or Bluetooth connectivity) makes them surprisingly susceptible to cyber threats.
So, what happens after the chaos of a cyberattack. How do you know your walkie-talkies are safe, working, and trustworthy again. In this series, you and I will break down exactly how to test your walkie-talkies after a cyberattack. We’ll get practical, look at real-world data, and even bust a myth or two about two-way radio security. Ready to take back control of your communications. Let’s dive in.
Understanding Walkie-Talkies in the Age of Cyber Threats
Before we get into the nitty-gritty of testing, let’s zoom out for a second and talk about what walkie-talkies actually are—and why they’re not as immune to cyberattacks as you might think.
Analog vs. Digital: The Basics
Traditionally, walkie-talkies were purely analog devices. They transmitted voice data over radio frequencies (RF) in real-time, without any encoding or digital processing. But fast-forward to today, and you’ll find digital two-way radios everywhere. These newer models convert your voice into digital signals, open the door to features like encryption, channel hopping, and integration with other networks (like Wi-Fi or cellular).
While that’s awesome for convenience and privacy, it also ups the ante on security challenges. According to a 2023 report by SecurityWeek, 62% of organizations now use digital walkie-talkies for mission-critical communications—a statistic that shows just how far the tech has come.
Why Walkie-Talkies Aren’t Immune
So, what makes walkie-talkies vulnerable. Here are a few modern realities:
- Jamming: Attackers use simple devices to flood the radio frequency and block communication.
- Eavesdropping: Unencrypted channels allow outsiders to listen in, and even digital signals can be intercepted if not properly secured.
- Unauthorized Access: Weak security means hackers can reprogram radios, access private channels, or impersonate your team.
- Firmware Manipulation: Digital radios run on firmware—software that’s hackable. Outdated firmware is a well-known security hole. In fact, a 2022 industry survey found that only 35% of users regularly update their walkie-talkie firmware.
If you think these risks are all theoretical, consider this: The number of reported walkie-talkie-related cyber incidents has doubled since 2020, especially during large-scale events and emergencies where seamless communication is crucial.
Why Testing Matters After an Attack
After a cyberattack, the integrity of your walkie-talkies is in question.
Maybe someone’s changed your channel settings, installed rogue firmware, or simply left you wide open to jamming. Failing to test and secure your radios after an incident isn’t just a technical risk—it’s a people risk. Your team could be left unable to coordinate, sensitive information could leak, or, worst-case, someone’s safety could be compromised.
Step-by-Step Guide: How to Test Walkie-Talkies After a Cyberattack
Okay, you know why it matters. Now let’s talk about what you actually do when the dust settles. Here’s a step-by-step roadmap you can follow (and trust me, it’s better to act than hope for the best).
1. Assess the Situation
First off, take a breath and gather information. What kind of cyberattack are you dealing with. Was it simple jamming, unauthorized access, or something more complex like firmware manipulation. Understanding the scope helps you prioritize your next steps.
2. Reset and Update
No matter the attack, start with the basics:
- Factory Reset: Restore your radios to their default settings to wipe out unauthorized changes.
- Firmware Update: Download the latest firmware from your manufacturer’s website. This patches known vulnerabilities—remember, only about 1 in 3 users do this regularly, so it’s a big deal.
- Change Frequencies: If your old channels were compromised, assign new ones and share them securely.
3. Physical Inspection
Now, actually inspect your walkie-talkies. Look for:
- Signs of tampering (scratches, loose components, open casing)
- Missing or swapped batteries
- Damaged antennas or peripherals
Even the best cyber defense won’t help if someone’s physically messed with your gear.
4. Connectivity Check
Test your radios in pairs and groups:
- Send and receive messages on each channel.
- Watch (or listen. ) for unexplained interference, dropouts, or static.
- Try at different ranges and locations.
If you spot unusual problems, it might indicate a lingering vulnerability or ongoing jamming attempt.
5. Security Feature Audit
Time to get a little technical:
- Encryption: Is it enabled and working. Test with encrypted and open channels.
- Passwords & Access Controls:
Are your walkie-talkies protected by up-to-date passwords or PINs. If your radios or their programming software support access controls, make sure you’ve updated all credentials since the attack. Weak, default, or shared passwords are an open invitation for future trouble.
Check that all users have unique, strong credentials and that old or unauthorized users have been removed from the system.
6. Test With Different Channels and Groups
Don’t just test one frequency or group—you need to be thorough. Cycle through all available channels and run communication tests with different teams or departments. Because attackers sometimes target specific channels, leaving others seemingly unaffected. If you only check your main channel, you might miss compromised secondary or backup frequencies. Document which channels work, which don’t, and note any suspicious activity (like unfamiliar voices or distorted transmissions) during your tests.
7. Document and Report Findings
It’s tempting to focus only on fixing the problem, but proper documentation is critical. Keep a detailed log of:
- What you tested and when
- Any anomalies or failures you encountered
- Security settings before and after changes
- Actions taken (resets, updates, reprogramming)
This record will save you major headaches if you ever need to investigate further incidents, involve a security expert, or show compliance with legal or industry requirements.
8. Know When to Get Help
If you find evidence of deep compromise, persistent jamming, or firmware that won’t update, don’t go it alone. This is the moment to call in a communications security expert. As Mark Phillips—a respected two-way radio security consultant—puts it, “Testing your walkie-talkies after a cyberattack isn’t just about pressing the talk button—it’s about ensuring your entire team can trust the channel. ” Sometimes, a professional audit or penetration test is the only way to guarantee your radios are truly clean and secure.
Advanced Testing Techniques for Enhanced Security
Basic checks are essential, but in a high-risk environment, going above and beyond is smart. Let’s look at some advanced methods organizations are using to bulletproof their walkie-talkie systems post-attack.
Use Spectrum Analyzers
A spectrum analyzer is like a superpower for your radio team. It lets you visualize all the signals in your frequency range, making it much easier to spot unauthorized transmissions or sources of interference. If you see strange spikes or signals that shouldn’t be there, you may be dealing with a lingering jammer or even a malicious device trying to mimic your network.
Run Penetration Tests (for Digital Radios)
Just like with computers and Wi-Fi networks, you can—and should—run penetration tests on digital walkie-talkies. This means bringing in professionals to try and “break in” to your system. They’ll attempt to intercept communications, bypass encryption, or exploit any firmware weaknesses. Seeing your network from a hacker’s perspective is invaluable for uncovering hidden vulnerabilities.
Simulate Attacks
Don’t wait for the real thing to hit twice. Regularly simulate common attacks, such as jamming or spoofing, to see how your radios and team respond. This isn’t just about the tech—it’s about building muscle memory for your users. Can they recognize a jammed channel. Do they know the backup plan. Practice makes perfect, especially when it comes to crisis communications.
Build Testing Into Your Routine
Post-breach testing should not be a one-time event.
Set up a regular schedule for both basic and advanced tests. Integrate walkie-talkie checks into your broader incident response plans so everyone knows what to do and when. Remember, the goal isn’t just to recover from one attack—it’s to prevent the next one.
By the Numbers: Walkie-Talkie Security in 2024
Let’s step back and see how all this plays out on a larger scale. The numbers might surprise you:
- 47% of communications outages in critical industries (like utilities and public safety) were traced to cyberattacks or malicious interference in the last two years, according to a 2023 Communications Security Survey.
- The rate of walkie-talkie-related cyber incidents has increased by 115% since 2020, driven by events like large festivals, protests, and emergencies.
- On average, organizations hit by a comms-related cyberattack experience 4. 2 hours of downtime—a costly hit in urgent environments.
- Adoption of encrypted digital walkie-talkies is on the rise, now at 69% in emergency services and 57% in logistics, up from less than half just three years ago.
- Yet, a 2023 survey found only 28% of walkie-talkie users test their devices for security vulnerabilities on a regular basis.
Let those stats sink in. The bottom line. Cyber threats to walkie-talkies are not only real—they’re increasing. But with proper testing and security practices, you can beat the odds.

Let’s shift gears and explore some lesser-known facts about walkie-talkie security and meet an expert at the forefront of communications defense. Ready for some radio revelations.
10 Fun Facts About Walkie-Talkie Security You Probably Didn’t Know
1. The First “Cyberattack” Was Just Eavesdropping
Long before the word “cyberattack” existed, people used simple receivers to listen in on police and emergency walkie-talkies. Encryption wasn’t standard until the late 20th century.
2. Digital Radios Can Be Hacked Like Smartphones
Modern digital walkie-talkies often run embedded software (firmware) that can be manipulated or infected—just like computers or phones. In one famous 2019 demonstration, researchers hacked into digital radios to inject audio messages.
3. Jamming Isn’t Always High-Tech
Believe it or not, DIY jamming devices can be built using parts from an old microwave. That’s why physical security and regular spectrum monitoring are as important as software updates.
4.
Some Radios “Phone Home”
Certain digital walkie-talkies can connect to Wi-Fi or cellular networks for advanced features. If not properly secured, they can transmit usage data—or even be remotely wiped—without the user knowing.
5. Encryption Standards Vary Widely
While some radios use AES-256 (the gold standard of encryption), others rely on proprietary or outdated ciphers that can be cracked in minutes using free online tools.
6. Over-the-Air Programming Can Be a Double-Edged Sword
Many organizations love the convenience of updating radio settings wirelessly. But if OTA (over-the-air) programming isn’t locked down, attackers can reprogram entire fleets remotely.
7. Fake Radios Are a Real Threat
Counterfeit radios, which look nearly identical to brand-name devices, sometimes come with pre-installed malware or backdoors, putting your entire comms network at risk.
8. Walkie-Talkies Have Been Used in Cybercrimes
In 2022, law enforcement in Europe uncovered a criminal gang using hacked walkie-talkies to coordinate heists—proving that radio security isn’t just a “what-if” scenario.
9. Cyber Hygiene Applies Here, Too
Just like with computers: changing default passwords, updating firmware, and training users reduce the risk of attack. Many real-world breaches happen because someone left the “admin” password unchanged.
10. There’s a Growing “Radio Hacker” Community
From DEF CON radio hacking villages to online forums, amateur and professional hackers regularly probe two-way radios for vulnerabilities—sometimes responsibly, sometimes not. Learning from these communities (or hiring them for penetration testing) can be your secret weapon.

FAQ: Your Top 10 Questions About Testing Walkie-Talkies After a Cyberattack
1. How do I know if my walkie-talkies have been compromised in a cyberattack.
Look for unusual behavior: unexpected voices on channels, garbled or missing transmissions, settings that have changed without explanation, or radios that won’t power on/off correctly. If you notice any of these after a suspected attack, it’s time to test comprehensively.
2. What’s the very first step after I suspect a cyberattack on my radios.
Immediately halt operational use if possible and start with a factory reset. This wipes unauthorized changes and settings. Next, update the firmware with an official version from your manufacturer. Remember: don’t use compromised radios until you’ve done these checks.
3. Can attackers still listen in after a cyberattack if I use encryption.
Possibly. If the attacker gained access to your encryption keys during the breach, they could still eavesdrop. That’s why rotating keys and changing all passwords after an incident is crucial—don’t just assume encryption alone will save the day.
4. How do I safely assign new channels and frequencies.
Work with your radio administrator or manufacturer to select fresh, unused channels. Share the new assignments securely with your team—never over the compromised radios. Document all changes for future reference.
5. Is physical inspection of the devices really necessary.
Absolutely. Cyberattacks sometimes go hand-in-hand with physical tampering: swapped batteries, altered antennas, or even hidden hardware. Make it a habit to check the physical integrity of all equipment after any security incident.
6.
How often should I test my radios for security vulnerabilities.
At minimum, every quarter—or more often if you operate in a high-risk environment. Regular tests (including simulated attacks and spectrum analysis) help you catch issues before they become disasters.
7. What’s the best way to train my team for post-attack response.
Drills, drills, drills. Practice not just technical resets but also communication protocols and social engineering awareness. As Mark Phillips says, “The biggest vulnerability is always people, not radios. ”
“Train up a child in the way he should go, and when he is old he will not depart from it. ” (Proverbs 22:6, NKJV) — the same wisdom applies to growing a security-minded team.
8. Are backup communication plans necessary if I have secure walkie-talkies.
Yes. Even the best radios can be jammed or hacked. Always establish alternative communication channels—cell phones, messengers, or even hard-copy instructions for critical events.
9. Who should I call if I can’t fix the problem myself.
If resets and updates don’t solve the situation, reach out to your radio manufacturer or a qualified communications security expert. Don’t hesitate—delays can lead to further breaches or operational setbacks.
