Want to guess what poses the largest threat to military operations today?
It’s cyber attacks against defence infrastructure and supply chains.
State-sponsored cyber attackers are targeting military networks, defence logistics systems, and the supplier networks that feed them. Their objectives? Gain strategic advantage by stealing valuable data and disrupting operations.
Here’s why this is such a big problem…
Most military supply chains were never designed to defend against cyberattacks. They connect hundreds (sometimes thousands) of contractors, vendors and third-party IT systems together. Every one of those connections is a potential weakness.
Attackers are already taking advantage of vulnerabilities within military supply chains.

Military Infrastructure Makes A Prime Target
Military systems make one of the most attractive targets for cyber criminals out there. Think about it…
Military infrastructure includes government networks, logistics software, weapons systems and more. Basically any high-value target you can think of that’s involved with national defence.
Attacking these targets allows hostile actors to hurt their adversaries without firing a single shot.
The numbers don’t lie:
Over 78% of military and defence organisations worldwide reported cyber attacks in 2023. That’s according to recent industry research.
Compare that to less than 65% the previous year. That’s a big jump.
But it’s not just the number of attacks. Attacks specifically targeting military infrastructure are growing fast too.
Chinese military cyber espionage activity increased by 150% in 2024. Russian cyber attacks against Ukrainian military and defence infrastructure was up 69% in the first half of 2024 compared to the same time last year.
The list goes on…
You get the point.
Nation-state attackers are infiltrating government and military systems at an alarming rate.
And they’re getting better at it.
Attackers primarily use phishing, malware, ransomware and zero-day vulnerabilities to gain initial access. From there, they often have weeks or months to roam undetected before they’re discovered.
If foreign governments can infiltrate military systems at will, that’s a serious problem for everyone.
Weakness In The Defence Supply Chain
Here’s the kicker…
When it comes to cyber security in military operations, most organisations focus on defending their military networks and weapon systems.
But the weakest link is often not these systems themselves…
It’s the supply chain.
Military logistics depends on hundreds, if not thousands of vendors. From third-party logistics service providers to government contractors… All of these connections represent potential vulnerabilities.
Effective defence project management demands secure coordination between every vendor, system and interface across the supply chain.
30% of all breaches now involve third-party compromise according to the 2025 Verizon DBIR. That’s up from 15% just one year prior.
When it comes to defence, with so many more suppliers involved, the risk is even higher.
Third-party vendors are often the entry point attackers are looking for. And you can bet they know every vendor connected to the military likely doesn’t have exactly the same level of security measures in place.
So they attack the weakest point. The supply chain.
Examples Of Cyber Attacks Against Military Systems
Wait… this is actually happening?
Yeah.
In 2024, the UK Ministry of Defence lost the personal information of around 270,000 military staff after hackers didn’t target the military network itself. They instead attacked a contractor who managed MoD payroll.
Among the data leaked? Names, bank account details, home addresses of current and former service personnel.
A contractor was responsible for one of the largest ever military breaches in the UK.
This isn’t unique to the UK either.
Nation-state actors have been attacking defence infrastructure supply chains since way before 2024.
In May of 2025, Russian cyber mercenaries launched a series of attacks against western logistics companies aiding in the transport of humanitarian aid to Ukraine.
Cyber espionage groups used phishing attacks, malware and stolen credentials to target transport and technology companies all across NATO nations.
In fact, supply chain attacks overall have doubled year-over-year since early 2024. Ransomware groups regularly claim attacks against businesses serving military and government contractors then publish leaked contracts, blueprints, schematics and other sensitive defence material on leak sites.
The pattern is clear:
Attackers are infiltrating military infrastructure via supply chain weaknesses at every opportunity they can.
How To Protect Defence Logistics From Cyber Threats
But what can be done about it? How can defence organisations defend against something that seems to be infiltrating networks from every angle?
There’s no silver bullet here.
Blocking cyber attacks against military supply chains requires a layered approach to security.
Below are some of the key steps organisations need to take:
- Implement a zero-trust security model. Verify every user, device and IP, every time they request access to anything.
- Vet every third-party vendor. Everyone from contractors to suppliers should be held to the same cyber security standards your organisation meets. Perform regular audits and third-party risk assessments.
- Monitor networks in real time. Use advanced threat detection tools that can alert suspicious behaviour across the entire supply chain. The sooner a breach is detected, the better the chance of stopping it.
- Have an incident response plan in place. Make sure every stakeholder in the supply chain knows exactly what to do in the event of a cyber attack. Include them in the planning.
- Have full visibility into the supply chain. Know every vendor, system and information flow that logistics operations touch. Any unknown connections are a vulnerability.
Some of the more forward-thinking defence organisations are treating cyber security as an integral part of their supply chain strategy. Not an afterthought.
And with good reason.
The threat landscape isn’t going to get any easier.
State-sponsored adversaries are allocating more resources to attacking military supply chains. Criminal ransomware gangs are becoming more aggressive. Tools and techniques will continue to improve.
Military organisations that take cyber security lightly are doing so at their own peril.
The Bottom Line
Cyber attacks against military systems are here to stay. In fact they will likely continue to grow.
Cyber attacks targeting military infrastructure and supply chains from nation-states and criminal groups increase every year.
- Military supply chains are attractive targets to cyber attackers
- Third-party vendors provide the easiest pathway to infiltrate military networks
- Protecting military logistics systems from cyber attacks requires multiple layers of security
If cyber security is going to be a strength for defence operations… Start treating it like one.
