Project 25 systems are targeted by interception, jamming, unauthorised transmission, and radio impersonation. Attackers may exploit weak key management, poor configuration, or exposed control channels to disrupt public-safety communications or eavesdrop on traffic. Security teams should protect radios and infrastructure, manage cryptographic material carefully, and watch for abnormal signal or equipment behaviour.
How Project 25 attacks work in practice
project 25 is attacked through the radio layer, not just through software. Interception, jamming, unauthorised transmission, and radio impersonation all target the trust that public-safety communications place in the channel itself. The practical question is whether an attacker can listen, inject, block, or masquerade as a legitimate radio source well enough to influence operations.
Those techniques matter because they can affect both confidentiality and availability at the same time. An interception attack can expose sensitive traffic, while jamming or replayed or spoofed transmissions can degrade command-and-control, delay response, or create false confidence in a unit’s status. Weak key handling and exposed control paths increase the chance that the radio layer becomes a usable entry point rather than a protected transport.
For defenders, the important distinction is between routine interference and deliberate abuse. Noise, misconfiguration, and overloaded systems can look similar to hostile activity, so teams need to understand what normal signal variation looks like before they can tell whether traffic is being blocked, copied, or impersonated.
Where the exposure usually sits
The highest-risk weaknesses are usually not exotic protocol flaws, but poor operational control. Weak key management can leave encrypted traffic or management functions exposed long after equipment is deployed. Poor configuration can create open or overly permissive channels, and exposed control interfaces can let an attacker alter settings, disable safeguards, or monitor traffic paths that should remain constrained.
Public-safety networks are also vulnerable to trust abuse across mixed environments. When radios, repeaters, gateways, and dispatch infrastructure are connected, a compromise in one component can affect the wider communication path. A limited compromise becomes more serious when the attacker can pivot into signalling, management, or identity-bearing configuration material that controls how the radio system behaves.
Teams should treat radio infrastructure as an operational security surface, not only a communications asset. The same State of NHI & AI Agent Breach Report 2026 is useful here because it shows how stolen credentials, service accounts, and exposed control paths often become the mechanism that turns a technical weakness into real-world abuse.
What defenders should verify before they trust the link
Protection starts with confirming that radios, base stations, repeaters, and management consoles are configured as tightly as the mission requires. If keying material is reused, shared too broadly, or left in long-lived form, the whole system becomes easier to intercept or impersonate. If configuration channels are reachable from untrusted networks, an attacker may not need to break encryption at all.
That is why OWASP Non-Human Identity Top 10 is a useful lens for the control plane around radios, especially where long-lived secrets, overprivilege, and secret leakage affect infrastructure that supports communications. It helps teams think about how machine-held credentials and management secrets can expand the blast radius of a compromise.
It is also worth validating whether monitoring can distinguish jamming from routine outage, and spoofing from legitimate traffic. A control is only useful if operators can see abnormal behaviour early enough to intervene, isolate affected channels, and preserve evidence from the device and management plane.
Risk and Threat Considerations
Project 25 attacks can create both immediate operational disruption and deeper compromise. Jamming may deny service outright, while impersonation or unauthorised transmission can mislead responders, create false dispatch signals, or hide an attacker’s presence long enough to manipulate operations.
Failure mechanism: The attacker exploits weak radio configuration, exposed control access, or poor key handling to inject, block, or decrypt traffic, then uses that position to influence communications or conceal activity.
Impact: Communications integrity drops, sensitive traffic may be exposed, and emergency response can be delayed or misdirected. In a public-safety context, even short-lived disruption can have outsized operational consequences.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 addresses the attack and risk surface, while NIST SP 800-53 Rev 5 and CIS Controls v8 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-02 — Secret Leakage | Project 25 control planes can be exposed through leaked management secrets. |
| NHI-05 — Overprivileged NHI | Radio infrastructure credentials can grant excessive control over communications systems. | |
| Recommendation — Protect and rotate radio-management secrets to reduce unauthorized access paths. Scope machine-held credentials to the minimum radio-management privileges. | ||
| NIST SP 800-53 Rev 5 | IA-5 — Authenticator Management | Project 25 protection depends on careful handling of cryptographic material and authenticators. |
| AC-4 — Information Flow Enforcement | Radio traffic and control channels need enforced boundaries against unauthorized transmission and exposure. | |
| Recommendation — Manage and rotate authenticators and related secrets on a defined lifecycle. Enforce flow restrictions between radio control paths and untrusted interfaces. | ||
| CIS Controls v8 | CIS-13 — Network Monitoring and Defense | Jamming, spoofing, and abnormal signal activity require continuous detection and response. |
| Recommendation — Monitor radio and infrastructure telemetry for interference and impersonation indicators. | ||
Practitioner Guidance
What to prioritise: Start with the controls that reduce blast radius, key exposure, and management-plane reach. If the radio can be configured or controlled remotely, that path deserves the same scrutiny as any privileged administration channel.
What to verify: Confirm that cryptographic material is rotated, scoped, and protected against reuse across devices or environments. Verify that dispatch, repeater, and infrastructure logs can show when a signal was unusual, unauthorised, or outside expected operating patterns.
What practitioners underestimate: Radio abuse is often operationally subtle. The first sign may be degraded clarity, unexpected silence, or a believable but false transmission rather than an obvious outage. If teams only look for complete failure, they can miss the compromise window.
Practitioner takeaway: Treat Project 25 security as a combined radio, configuration, and key-management problem, because attackers usually win by abusing trust in the communication path rather than by breaking the air interface alone.
