In the landscape of 21st-century conflict, the most dangerous weapon is often the one sitting in a pocket. As digital connectivity becomes inseparable from daily life, the disciplines of Information Security (INFOSEC) and Operational Security (OPSEC) have moved from the periphery of military doctrine to the center of personal and national safety. While these terms are often used interchangeably, they represent two distinct philosophies of protection.

The Shield and the Shadow

INFOSEC is primarily concerned with the "what" and the "how" of data protection. It is built around the CIA triad: confidentiality, integrity, and availability. This discipline focuses on the technical and physical barriers—encryption, firewalls, and multi-factor authentication—that prevent unauthorized access to sensitive information. If information security is the lock on a safe, it ensures that only those with the key can see what is inside.

OPSEC, by contrast, is far more abstract. It is the process of identifying critical information and analyzing "friendly" actions to see if they reveal patterns to an adversary. OPSEC is not about the data itself, but about the "shadows" that data casts. Even if a message is perfectly encrypted (strong INFOSEC), the mere act of sending it at a specific time from a specific location can reveal a user’s intentions (weak OPSEC).

Lessons from History: The Purple Dragon

The formalization of OPSEC stems from the Vietnam War’s "Operation Purple Dragon." Despite having secure communications, U.S. forces found that the North Vietnamese were consistently predicting bombing raids. Investigators discovered that the enemy wasn't hacking radios; they were watching "indicators." A spike in laundry services for flight suits or an increase in late-night pizza deliveries to command centers served as non-secret, observable actions that revealed classified timelines. This historical lesson remains relevant today: an adversary does not need to steal your secrets if they can simply observe your habits.

The Modern Honeytrap

Today, these vulnerabilities are exploited through social engineering. Intelligence operatives frequently use AI-generated profiles on dating and social media apps to target individuals in sensitive positions. By building rapport, these bad actors can elicit location data or convince targets to download third-party applications. Once installed, these "honeytrap" apps function as sophisticated malware, providing adversaries with remote access to microphones, cameras, and GPS data. This transition from a conversation to a technical breach illustrates how a failure in personal OPSEC leads directly to a catastrophic INFOSEC failure.

The Risk of Digital Exhaust

The concept of "digital exhaust" describes the trail of data humans leave behind through routine activities. In 2018, the "Strava-gate" incident revealed that fitness tracking heat maps could inadvertently map the perimeters of secret military bases simply by recording the morning jogs of personnel. Similarly, the rise of "TikTok War" footage poses immediate tactical risks. Open-source intelligence (OSINT) analysts can geolocate a soldier’s position within minutes by analyzing architectural details or vegetation in the background of a video.

Ultimately, the modern battlefield proves that security is no longer just a technical challenge for IT professionals. It is a behavioral challenge for everyone. Understanding the difference between protecting data and protecting patterns is the first step in navigating a world where every digital footprint can be tracked.

Episode #778: The Invisible Front: OPSEC and INFOSEC in Modern War

Daniel Daniel's Prompt
Daniel
Herman and Quirin, we’ve discussed open source intelligence and military affairs, but we haven’t yet touched upon the concepts of operational security (OPSEC) and information security (INFOSEC).

Could you explain the difference between INFOSEC and OPSEC? This is particularly relevant given recent instances in Israel where militant groups have used fake social media profiles to lure IDF reservists and gather intelligence. Furthermore, what are the risks of soldiers having personal smartphones in the field and uploading content to platforms like Instagram or TikTok? It seems like a significant failure of operational security that can lead to doxing and other mission risks.

Finally, I’d love to hear how these military doctrines of INFOSEC and OPSEC have resonated outwards and influenced best practices in cybersecurity and other fields.
Corn
Hey everyone, welcome back to My Weird Prompts. I am Corn, and I am here with my brother as always, coming to you from a very rainy Jerusalem on this twenty-second of February, twenty-twenty-six.
Herman
Herman Poppleberry here. It is good to be back in the studio, Corn. And you are right, the weather outside is a bit gloomy, but the topic today is incredibly sharp. It hits very close to home for us here in Israel, especially given the events of the last few years.
Corn
It really does. We are diving into a prompt from Daniel today that touches on the invisible architecture of modern conflict. He wants us to break down the world of operational security and information security, or OPSEC and INFOSEC.
Herman
This is a fantastic prompt because these terms are thrown around constantly in news reports and tech blogs, often as if they mean the same thing. But in a military or high-stakes intelligence context, they are distinct disciplines with very different philosophies. As Daniel pointed out, the stakes for getting them wrong have never been higher. We are living in an era where the line between the front lines and civilian life has been completely erased by the smartphone in your pocket.
Corn
Exactly. We have seen some wild and frankly terrifying stories lately about how these vulnerabilities are being exploited right here in our backyard. So, Herman, let us start with the foundation. You have been digging into the doctrine. How do we actually separate INFOSEC from OPSEC?
Herman
The easiest way to visualize it is that information security, or INFOSEC, is about the data itself. It is the technical, administrative, and physical side of protecting information from unauthorized access, use, disclosure, disruption, or destruction. If you think of your life as a castle, INFOSEC represents the height of the walls, the strength of the gate, and the guards checking IDs at the entrance. It is built around what we call the CIA triad: confidentiality, integrity, and availability.
Corn
I have heard that term before. Can you break down the CIA triad for us?
Herman
Of course. Confidentiality means ensuring that only authorized individuals have access to the information. Integrity means the data has not been tampered with or altered by an unauthorized party. And availability means that the systems and the data are actually there when the authorized users need them. If a hacker encrypts your files with ransomware, they have attacked the availability. If they leak your emails, they have attacked the confidentiality. If they change the numbers on a bank transfer, they have attacked the integrity. It is very technical. It involves encryption, firewalls, multi-factor authentication, and secure servers.
Corn
Okay, so INFOSEC is the shield around the information. It is the "what" and the "how" of protection.
Herman
Exactly. Now, operational security, or OPSEC, is much more abstract and, in many ways, much harder to master. It is not just about the data; it is about the actions, the patterns, and the process. OPSEC is the process of identifying critical information and then analyzing friendly actions to see if they can be observed by adversary intelligence systems. The goal of OPSEC is to deny an opponent the specific pieces of information they need to figure out your intentions, your capabilities, or your timeline.
Corn
So if INFOSEC is the lock on the safe, OPSEC is making sure no one sees you walking toward the safe or notices that you are carrying a big heavy bag into the building at three in the morning.
Herman
That is a perfect way to put it. In fact, the formal doctrine of OPSEC actually has a five-step process that military planners use. Step one is identifying your critical information. What does the enemy want to know? Step two is analyzing the threat. Who is looking for it? Step three is analyzing your vulnerabilities. How are we leaking this? Step four is assessing the risk. If they find out, how bad is it? And step five is applying the countermeasures.
Corn
You mentioned earlier that the term OPSEC comes from the Vietnam War. I would love to hear that story because it really illustrates the difference.
Herman
It is a classic piece of military history. In nineteen-sixty-six, the United States was running a massive bombing campaign called Operation Rolling Thunder. The problem was that the North Vietnamese seemed to know exactly when and where the bombers were coming. They were moving their anti-aircraft batteries and clearing out targets before the planes even took off. The U.S. was baffled. They had great INFOSEC. Their flight plans were classified and encrypted. Their communications were secure. They checked for spies. Nothing.
Corn
So how were they getting the info?
Herman
A team called Operation Purple Dragon was formed to investigate. They realized the North Vietnamese weren't hacking the radios; they were watching the "indicators." They noticed that every time a big mission was planned, there was a surge in laundry services at the air bases in Guam and Thailand. The pilots wanted clean flight suits. They noticed a spike in pizza deliveries to the command centers late at night. They even watched the local markets to see when the military was buying extra supplies. By piecing together these non-secret, observable actions, the North Vietnamese could predict a strike with incredible accuracy. That was the birth of OPSEC as a formal discipline. It is the "meta-data" of human behavior.
Corn
That is fascinating. It is about the shadows cast by the information, not the information itself. And that brings us directly to the current situation here in Israel that Daniel mentioned. We have seen these reports about militant groups, specifically Hamas and Hezbollah, using fake social media profiles to target soldiers. That feels like a massive OPSEC failure that leads to an INFOSEC breach.
Herman
It is the ultimate modern "honeytrap." This is a classic social engineering attack. What happens is an intelligence operative—often sitting in a room in Gaza or even abroad—creates a profile of an attractive woman on Instagram, Telegram, or dating apps like Tinder and Bumble. They use AI-generated photos or stolen images from real influencers to make the profile look legitimate. Then, they start reaching out to soldiers or reservists.
Corn
And because so many people are on high alert or feeling lonely during a deployment, they might be more susceptible to a friendly message.
Herman
Exactly. They strike up a conversation, build some rapport, and use what we call "elicitation techniques." They will say things like, "Oh, you look so brave in your uniform. Are you stationed somewhere dangerous? Is it cold in the north right now?" That is a direct attempt to get the soldier to commit an OPSEC violation by revealing their location or unit. But it goes deeper. Once they have built trust, they will say, "This app is glitchy, let us move to a more private chat app," and they send a link to a custom-made application.
Corn
I remember seeing the names of some of these apps in the news. They had names like "GlanceLove" or "Golden Cup."
Herman
Right. And the soldier thinks they are just downloading a niche dating app or a World Cup scores app. But the moment they install it, the trap snaps shut. This is where it transitions from an OPSEC failure—talking to a stranger—to a catastrophic INFOSEC breach. These apps are actually sophisticated malware. Once installed, the adversary has full remote access to the phone. They can turn on the microphone to listen to briefings, they can use the camera to see inside a command center, they can scrape the entire contact list, and most importantly, they can track the GPS location in real time.
Corn
So you have a bugged device sitting right in the middle of a staging area or a tactical operations center.
Herman
Precisely. And in the Israeli context, this is amplified by what Daniel called the "people's army." In Israel, the military isn't some distant, professional caste. It is everyone. You have high-tech engineers, lawyers, and students who are civilians on Friday and wearing a uniform on Saturday. They are carrying the same smartphone they use for their business, their family group chats, and their social media presence. That transition is a security nightmare.
Corn
It seems like the digital habits of a civilian are fundamentally at odds with the requirements of a soldier. If I am used to posting my lunch, my workouts, and my location every day, I am not going to magically stop just because I am in uniform.
Herman
That is the "digital exhaust" problem. A career soldier might be trained in "digital silence," but a reservist is a civilian who happens to be a soldier. Their digital footprint is already massive. An adversary doesn't need to hack a secure IDF server to find out where a specific unit is moving. They just need to find the one guy in the unit who forgot to turn off his location services on a fitness app like Strava or Garmin.
Corn
You mentioned Strava, and we have to talk about "Strava-gate" from a few years ago. That was a huge wake-up call for the global military community.
Herman
It was a perfect example of an OPSEC fail through a third-party app. In twenty-eighteen, Strava released a "heat map" showing the activity of all its users worldwide. It looked like a beautiful glowing map of the world. But security researchers quickly realized that in places like Syria, Afghanistan, and Djibouti, the only people using Strava were Western soldiers. You could see the exact perimeters of secret "black sites" and forward operating bases because the soldiers were running laps around the fence line every morning. You could even see the supply routes because they would go for bike rides between bases.
Corn
And again, that wasn't a hack. The data was shared voluntarily.
Herman
Exactly. It was a failure to understand how individual data points, when aggregated, reveal a secret pattern. That is the essence of OPSEC. Now, fast forward to today, and we have the "TikTok War" phenomenon. We see soldiers in Gaza or on the northern border filming themselves. Sometimes it is just a dance, sometimes it is a video of them eating dinner in a captured house. Daniel asked about the mission risks here. Herman, what are the tactical implications of a ten-second TikTok video?
Herman
They are immediate and potentially lethal. First, there is geolocation. Even if the soldier doesn't say where they are, the background of the video provides everything an intelligence officer needs. They use a technique called "OSINT" or Open Source Intelligence. They look at the skyline, the specific architecture of a minaret, the shape of a water tower, or even the type of vegetation. There are people on the internet who can find a specific street corner in Gaza within minutes of a video being posted just by looking at the cracks in the pavement and cross-referencing them with satellite imagery.
Corn
And once they have the location, they have a target.
Herman
Exactly. If a soldier posts a video in real time, that building can be targeted by a mortar, an anti-tank missile, or a suicide drone before the video even finishes uploading. But it is also about the "order of battle." If I see a specific unit insignia on a shoulder patch, or a specific modification on a tank in the background, I now know which brigade is operating in that sector. I can estimate their strength, their equipment, and their morale. You are giving the enemy a free, high-definition look at your front lines.
Corn
Then there is the "doxing" risk Daniel mentioned. This feels like a newer, more personal threat for soldiers in twenty-twenty-six.
Herman
It is a form of "lawfare" and personal harassment. Groups like the Hind Rajab Foundation and various activist collectives are actively scraping social media for any footage posted by Israeli soldiers. They use facial recognition software—which has become incredibly cheap and accurate—to identify the soldiers. Once they have a face, they find the LinkedIn profile, the Facebook page, and the home address.
Corn
And then what?
Herman
Then they build a dossier. They might send that information to international legal bodies, claiming the soldier was involved in a specific incident. Or, more commonly, they target the soldier's civilian life. They contact their employer and demand they be fired. They harass their family members. They post their phone numbers on Telegram channels that advocate for violence. It creates a situation where the war follows the soldier home. The "front line" is now their front door. It is a psychological weight that previous generations of soldiers never had to carry.
Corn
It feels like the military hierarchy is struggling to keep up. Why hasn't there been a total ban on smartphones in the field? Surely that would solve the problem.
Herman
They have tried. In high-security units or during specific operations, phones are confiscated and put in "Faraday bags" that block all signals. But a total, military-wide ban is almost impossible to enforce in twenty-twenty-six. First, there is the morale aspect. In a long, grinding conflict, being able to video call your kids or your spouse is the only thing keeping some soldiers sane. If you take that away for months, you risk a total collapse in morale.
Corn
And phones are actually useful tools on the battlefield now, right?
Herman
They are indispensable. Soldiers use them for offline maps, for translating captured documents, for calculating mortar trajectories with specialized apps, and for quick communication when the official radio networks are jammed or down. The smartphone is a multi-tool. The problem is that it is a "leaky" tool. It is constantly trying to talk to cell towers, Wi-Fi networks, and satellites. Even if you aren't posting to TikTok, your phone might be "pining" a local cell tower that is controlled by the enemy.
Corn
So the challenge isn't total abstinence; it is "digital discipline." But how do you teach that to a twenty-year-old who has lived their entire life on camera?
Herman
It is a massive training hurdle. The IDF's C4I Directorate—which handles telecommunications and cyber defense—now runs mandatory workshops. They will actually show soldiers their own digital footprints. They will say, "Here is a photo you took three years ago at a party, and here is how we used it to find your current position." They even run their own "honeytrap" exercises. They will create a fake profile, lure a soldier into a conversation, and then when the soldier agrees to meet or download an app, they get a message saying, "You just been caught by your own security team. Here is why you are a liability."
Corn
That is a tough lesson to learn. But I want to pivot to the last part of Daniel's prompt, which I think is really relevant for our listeners who aren't in the military. How have these doctrines—INFOSEC and OPSEC—moved into the corporate world and our daily lives?
Herman
This is where the "weird prompts" get practical. Almost every major trend in modern cybersecurity is just military INFOSEC and OPSEC rebranded for the private sector. Take the concept of "Zero Trust Architecture," or ZTA. In the old days of corporate security, you had a "perimeter." Once you were inside the office and logged into the network, you were trusted.
Corn
Like the castle walls you mentioned earlier.
Herman
Exactly. But in a world of remote work and cloud computing, there is no perimeter. Zero Trust says, "I don't care if you are the CEO sitting in the main office; I am going to verify your identity, your device, and your location every single time you try to access a file." It is the military principle of "Need to Know" applied to every single digital interaction. You are never trusted by default.
Corn
And what about OPSEC in the corporate world?
Herman
We see it in "threat hunting" and "Digital Risk Protection." Companies now hire firms to do exactly what Operation Purple Dragon did. They monitor the dark web to see if hackers are talking about their employees. They look for "typo-squatting" domains—like "myweirdprompts-dot-co" instead of "dot-com"—that might be used for phishing. They even monitor the social media of their executives to make sure they aren't accidentally revealing sensitive information.
Corn
I imagine a CEO posting a selfie in a private jet could be a huge OPSEC fail if the tail number of the plane is visible, or if the reflection in their sunglasses shows a sensitive document.
Herman
Exactly! There are actually "corporate OPSEC" consultants who specialize in scrubbing the digital footprints of high-net-worth individuals. They look for things like "property tax records" or "voter registration data" that could be used by a kidnapper or a corporate spy. It is the same process: identify critical info, analyze the threat, and apply countermeasures.
Corn
It also shows up in how we handle "Business Email Compromise" or BEC. That is basically the corporate version of the honeytrap, right?
Herman
It is exactly the same psychological exploit. Instead of an attractive woman on Tinder, it is an email that looks like it is from the CFO, sent on a Friday afternoon, saying, "I am in a meeting and I need you to wire fifty thousand dollars to this new vendor immediately or the deal falls through." It creates a sense of urgency and authority to bypass the technical INFOSEC layers. The countermeasure isn't a better firewall; it is a human-level OPSEC rule: "Always verify a wire transfer request with a phone call on a known number."
Corn
It is interesting how it all comes back to human psychology. You can have the best encryption in the world, but if you can convince the person with the key to just hand it over, the encryption doesn't matter.
Herman
That is the "Layer Seven" problem—the human layer. And as we move deeper into twenty-twenty-six, AI is making this even more complex. We are seeing "Deepfake" audio and video being used in these attacks. Imagine a soldier getting a video call from their commander, and it looks and sounds exactly like them, telling them to move to a new location. Or a CEO getting a call from their board chairman.
Corn
That is terrifying. So, how do we defend against that? Is there such a thing as "AI-driven OPSEC"?
Herman
There is. We are starting to see the rise of "personal security guardians." These are AI agents that sit on your devices—with your permission—and act as a sort of digital conscience. If you are about to post a photo, the AI scans the background for sensitive items, blurs out faces of people who haven't given consent, and checks the metadata for GPS coordinates. It might even warn you, "Hey, you have been talking to this new contact for three days and they have asked four questions about your workplace. This matches a known social engineering pattern."
Corn
It is like having a little Herman Poppleberry sitting on your shoulder, whispering, "Don't click that link, Corn!"
Herman
Exactly! But it brings up a massive privacy tension. Do you want an AI—especially one potentially controlled by your employer or the government—scanning every photo and message you send? In a democratic society like Israel, that is a very hard sell. We are seeing a constant negotiation between the need for security and the right to a private life.
Corn
It really feels like the "front line" has become a lifestyle. If you are a reservist, or even just a person with access to sensitive data, you are never truly "off duty." The internet has a perfect and permanent memory. If you leak your location today, it could be used against you five years from now.
Herman
That is the most profound change. In the twentieth century, OPSEC was something you did during a mission. In the twenty-first century, OPSEC is how you live your life. It is about understanding your "digital exhaust." Every time you interact with a smart device, you are leaving a trail. If you don't manage that trail, someone else—whether it is a militant group, a corporate spy, or a common criminal—will use it to find you.
Corn
So, for our listeners who are just trying to navigate this world, what are the three big takeaways?
Herman
Number one: Understand the difference. INFOSEC is your password and your firewall; OPSEC is your behavior and your patterns. You need both. Number two: Audit your digital exhaust. Check your privacy settings on every app, especially fitness trackers and social media. Turn off location services unless you absolutely need them. And number three: Practice "healthy paranoia." If a stranger reaches out to you online and the conversation feels too good to be true, or if they start asking "innocent" questions about your job or your location, back away. Verify, then maybe trust a little bit.
Corn
"Verify, then maybe trust a little bit." I like that. It is a bit more cynical than "Trust but verify," but it fits the world of twenty-twenty-six.
Herman
It is the only way to stay safe. The Israel example is a stark warning for the rest of the world. When a "people's army" meets the "social media age," the friction is intense. We are the test case for how a modern society maintains security when every citizen is a potential leak.
Corn
Well, I think we have thoroughly covered Daniel's prompt. It is a lot to process, and it definitely makes me want to go home and check my own settings again.
Herman
Me too, Corn. Me too.
