The FBI has issued an urgent warning regarding cybercriminals targeting outdated routers, particularly those manufactured around 2010 or earlier. The alert, released on May 7, 2025, emphasizes the risks associated with using unpatched and unprotected devices, which have become vulnerable gateways for malware and illegal operations. As these aging devices often go unnoticed, victims remain unaware that their routers may be exploited to facilitate anonymous cybercrime activities without their knowledge.

The FBI’s Public Service Announcement on Router Vulnerabilities
The FBI’s Internet Crime Complaint Center (IC3) alerted both individuals and organizations on May 7, 2025, emphasizing the growing danger posed by outdated routers lacking critical security patches. As these older devices become more common in homes and small offices, they have become prime targets for cybercriminals. Many of these routers, particularly those made before 2010, are no longer supported by manufacturers, meaning they do not receive necessary firmware updates to fix known weaknesses.
According to the announcement, cybercriminals have been exploiting these vulnerabilities using a malware strain known as “TheMoon.” This malicious software enables attackers to gain control of the routers, installing proxy services that facilitate illicit activities while concealing the criminals’ identities. The alert notes that compromised routers can unknowingly contribute to criminal enterprises, transforming effectively harmless home devices into tools of cybercrime.
Vulnerable Router Models Listed by the FBI
In its bulletin, the FBI identified specific router models frequently targeted by attackers. These include:
- Cisco M10
- Cisco Linksys E1500
- Cisco Linksys E1550
- Cisco Linksys WRT610N
- Cisco Linksys E1000
- Cradlepoint E100
- Cradlepoint E300
- Linksys E1200
- Linksys E2500
- Linksys E3200
- Linksys WRT320N
- Linksys E4200
- Linksys WRT310N
These models are typically over a decade old, making them especially susceptible to breaches due to unpatched security flaws. With manufacturers ceasing firmware updates, these devices present an easy door for attackers, who require minimal effort to exploit them.
Mechanisms of Router Exploitation by Cybercriminals
Cybercriminals often exploit routers by targeting those with remote administration functionalities exposed to the internet. By scanning the network for such vulnerabilities, they can utilize known firmware flaws to gain entry without needing password access. A single malicious web request can manipulate an older router into executing harmful code, giving attackers a foothold.
The malware “TheMoon,” for instance, first detected in 2014, has been known to turn infected routers into proxy nodes that mask the hackers’ identities. Instead of direct attacks, this malware reroutes third-party traffic through compromised devices, effectively hiding the source of malicious actions. Platforms within the cybercrime underground have even started selling access to these routing devices as “residential proxies,” making them useful tools for anonymity and illegal activities.
Risks Posed to Users and Businesses
For ordinary consumers, having a compromised router can lead to a variety of inconveniences such as slow internet speeds, unwanted phishing attempts, and exposure to spyware. More importantly, there is potential legal liability if criminals use the hijacked router to conduct illegal activities. Businesses face even greater threats: outdated routers can enable deeper network intrusions, data theft, and ransomware attacks. In critical sectors, a breach could have severe consequences that impact operational safety and regulatory compliance.
Furthermore, when cybercriminals exploit a network device, it not only endangers individuals and businesses but also puts the integrity of the larger internet ecosystem at risk. Unchecked, these compromised routers can contribute to larger botnets that challenge law enforcement and require significant resources to combat.
Essential Steps to Secure Your Router
Given the alarming threats posed by outdated routers, it is crucial to take proactive steps to enhance your network security. Here are six effective strategies:
1) Replace Old Routers: If your router is older than five to seven years, it’s advisable to upgrade it. Check the model number and search online for its last firmware update. If it has been years since an update, consider purchasing a newer model that ensures continued support and security.
2) Keep Firmware Updated: Your router’s firmware needs regular updates like any other tech device. Log in to your router settings to check for updates. Many manufacturers provide easy access for firmware updates through dedicated applications.
3) Disable Remote Access: While convenient, remote access opens doors for hackers. Turn off this feature in the router settings to enhance security.
4) Implement Strong Passwords: Default login credentials are often the first targets for hackers. Change these to a strong, unique password, ideally using a password manager to help generate complex passwords.
5) Monitor Router Behavior: If you notice unusual internet performance or unknown devices connected to your network, take immediate action. Update firmware, change passwords, and consult with your internet provider if necessary.
6) Report Issues: If you suspect that your router has been compromised, report it to the Internet Crime Complaint Center to help authorities assess and mitigate broader threats.
