U.S. Agencies Consider Restrictions on TP-Link Routers Over Security Risks

 



A coordinated review by several federal agencies in the United States has intensified scrutiny of TP-Link home routers, with officials considering whether the devices should continue to be available in the country. Recent reporting indicates that more than six departments and agencies have supported a proposal recommending restrictions because the routers may expose American data to security risks.

Public attention on the matter began in December 2024, when major U.S. outlets revealed that the Departments of Commerce, Defense and Justice had opened parallel investigations into TP-Link. The inquiries focused on whether the company’s corporate structure and overseas connections could create opportunities for foreign government influence. After those initial disclosures, little additional information surfaced until the Washington Post reported that the proposal had cleared interagency review.

Officials involved believe the potential risk comes from how TP-Link products collect and manage sensitive information, combined with the company’s operational ties to China. TP-Link strongly disputes the allegation that it is subject to any foreign authority and says its U.S. entity functions independently. The company maintains that it designs and manufactures its devices without any outside control.

TP-Link was founded in Shenzhen in 1996 and reorganized in 2024 into two entities: TP-Link Technologies and TP-Link Systems. The U.S. arm, TP-Link Systems, operates from Irvine, California, with roughly 500 domestic employees and thousands more across its global workforce. Lawmakers previously expressed concern that companies with overseas operations may be required to comply with foreign legal demands. They also cited past incidents in which compromised routers, including those from TP-Link, were used by threat actors during cyber operations targeting the United States.

The company has grown rapidly in the U.S. router market since 2019. Some reports place its share at a majority of consumer sales, although TP-Link disputes those figures and points to independent data that estimates a smaller share. One industry platform found that about 12 percent of active U.S. home routers are TP-Link devices. Previous reporting also noted that more than 300 internet providers distribute TP-Link equipment to customers.

In a separate line of inquiry, the Department of Justice is examining whether TP-Link set prices at levels intended to undercut competitors. The company denies this and says its pricing remains sustainable and profitable.

Cybersecurity researchers have found security flaws in routers from many manufacturers, not only TP-Link. Independent analysts identified firmware implants linked to state-sponsored groups, as well as widespread botnet activity involving small office and home routers. A Microsoft study reported that some TP-Link devices became part of password spray attacks when users did not change default administrator credentials. Experts emphasize that router vulnerabilities are widespread across the industry and not limited to one brand.

Consumers who use TP-Link routers can reduce risk by updating administrator passwords, applying firmware updates, enabling modern encryption such as WPA3, turning on built-in firewalls, and considering reputable VPN services. Devices that no longer receive updates should be replaced.

The Department of Commerce has not issued a final ruling. Reports suggest that ongoing U.S. diplomatic discussions with China could influence the timeline. TP-Link has said it is willing to improve transparency, strengthen cybersecurity practices and relocate certain functions if required. 

CISA Warns of Renewed Exploits Targeting TP-Link Routers with Critical Flaws

 

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has raised fresh concerns about several outdated TP-Link router models that are being actively exploited by cybercriminals. Despite the flaw being identified years ago, it has re-emerged in recent attack campaigns, prompting its addition to CISA’s Known Exploited Vulnerabilities (KEV) catalog. 

The security issue is a command injection vulnerability with a high severity rating of 8.8. It impacts three specific models: TP-Link TL-WR940N, TL-WR841N, and TL-WR740N. The flaw exists within the routers’ web-based management interface, where improperly validated input allows hackers to execute unauthorized commands directly on the devices. This makes it possible for attackers to gain control of the routers remotely if remote access is enabled, or locally if they’re on the same network. 

Although this vulnerability has been publicly known for years, recent activity suggests that malicious actors are targeting these devices once again. According to cybersecurity researchers, the attack surface remains significant because these routers are still in use across many households and small offices. 

CISA has mandated that all federal agencies remove the affected router models from their networks by July 7, 2025. It also strongly recommends that other organizations and individuals replace the devices to avoid potential exploitation. 

The affected routers are particularly vulnerable because they are no longer supported by the manufacturer. The TL-WR940N last received a firmware update in 2016, the TL-WR841N in 2015, and the TL-WR740N has gone without updates for over 15 years. As these devices have reached end-of-life status, no further security patches will be provided. Users are urged to upgrade to newer routers that are regularly updated by manufacturers. 

Modern Wi-Fi routers often include enhanced performance, support for more devices, and built-in security protections. Some brands even offer network-wide security features to safeguard connected devices against malware and intrusion attempts. Additionally, using antivirus software with extra security tools, such as VPNs and threat detection, can further protect against online threats. 

Outdated routers not only put your personal information at risk but also slow down internet speed and struggle to manage today’s connected home environments. Replacing obsolete hardware is an important step in defending your digital life. 

Ensuring you’re using a router that receives timely security updates, combined with good cybersecurity habits, can significantly reduce your exposure to cyberattacks. 

CISA’s warning is a clear signal that relying on aging technology leaves both individuals and organizations vulnerable to renewed threats.

FBI Warns Consumers to Replace Outdated Routers Hijacked by TheMoon Malware

 

The FBI has issued an urgent warning to American consumers and businesses: replace outdated internet routers immediately or risk becoming an unwitting accomplice in cybercrime. According to the agency, cybercriminals are actively targeting “end-of-life” routers—older models that no longer receive security updates from manufacturers—and infecting them with a sophisticated variant of TheMoon malware. Once compromised, these routers are hijacked and repurposed as proxy servers that enable criminals to mask their identities while conducting illegal activities online. 

These include financial fraud, dark web transactions, and cyberattacks, all executed through unsuspecting users’ networks. Because these routers lack updated firmware and security patches, they are especially vulnerable to remote infiltration and control. TheMoon malware, which first emerged in 2014, has evolved into a more potent threat. It now scans for open ports and installs itself without requiring a password. Once embedded, it silently operates in the background, routing illicit activity and potentially spreading to other devices within the network. The malware’s stealthy behavior often leaves users unaware that their home or business network has become part of a criminal infrastructure. 

The FBI specifically warned that routers manufactured in 2010 or earlier are particularly at risk—especially if features like remote administration are still enabled. Older Linksys models such as E1200, E2500, E1000, E4200, E1500, E300, E3200, WRT320N, E1550, WRT610N, E100, M10, and WRT310N are listed among the most vulnerable devices. Signs of a compromised router may include overheating, unexplained changes to settings, or erratic internet connectivity. In many cases, users may not even realize their equipment is outdated, making them easy targets for attackers seeking anonymous access to the web. 

To defend against these threats, the FBI strongly advises replacing unsupported routers with modern, secure models. Users should also disable remote access functions, install the latest security patches, and use complex, unique passwords to further protect their networks. If anyone suspects their router has been hijacked or detects suspicious activity, they are encouraged to file a report with the FBI’s Internet Crime Complaint Center (IC3). 

As cybercriminals become more innovative, relying on outdated technology increases exposure to serious digital threats. This latest alert is a stark reminder that cybersecurity begins at home—and that even something as common as a router can become a gateway for criminal exploitation if not properly secured.

D-Link Urges Replacement of End-of-Life VPN Routers Amid Critical Security Vulnerability

 

D-Link has issued a strong warning to its customers, advising them to replace certain end-of-life (EoL) VPN router models immediately. This follows the discovery of a critical unauthenticated remote code execution (RCE) vulnerability that will not be addressed with security patches for the affected devices. The vulnerability was reported to D-Link by security researcher “delsploit,” although technical details have been withheld to prevent widespread exploitation. The flaw impacts all hardware and firmware versions of the DSR-150, DSR-150N, DSR-250, and DSR-250N models, particularly firmware versions 3.13 to 3.17B901C. 

These routers, which have been popular among home offices and small businesses worldwide, officially reached their end-of-service (EoS) status on May 1, 2024. D-Link’s advisory makes it clear that no further security updates will be issued for these devices. Customers are strongly encouraged to replace the affected models to avoid potential risks. For users who continue using these devices despite the warnings, D-Link suggests downloading the latest available firmware from their legacy website. 

However, it is important to note that even the most up-to-date firmware will not protect the routers from the RCE vulnerability. The company also cautions against using third-party open-firmware solutions, as these are unsupported and will void any product warranties. D-Link’s policy not to provide security fixes for EoL devices reflects a broader strategy within the networking hardware industry. The company cites factors such as evolving technologies, market demands, and product lifecycle maturity as reasons for discontinuing support for older models. The issue with D-Link routers is not an isolated case. 

Earlier this month, researcher “Netsecfish” revealed CVE-2024-10914, a command injection flaw affecting thousands of EoL D-Link NAS devices. Similarly, three critical vulnerabilities were recently disclosed in the D-Link DSL6740C modem. In both instances, the company chose not to release updates despite evidence of active exploitation attempts. The growing trend of security risks in EoL networking hardware highlights the importance of timely device replacement. 

As D-Link warns, continued use of unsupported routers not only puts connected devices at risk but may also leave sensitive data vulnerable to exploitation. By replacing outdated equipment with modern, supported alternatives, users can ensure stronger protection against emerging cybersecurity threats.

The Hidden Dangers of Compromised Wi-Fi Routers

 


Cybercriminals who attack routers are swift and precise, spending countless hours studying network vulnerabilities to compromise sensitive data and then taking advantage of those vulnerabilities to compromise the router. The term "router hacking" refers to taking control of a user's router without their consent by a cybercriminals.

The Wi-Fi hacker, like other types of hackers, relies on security measures that a user may have implemented to protect themselves against the hack - often the administrator password for their router or an unpatched vulnerability in their system. The hacker has a variety of tricks that he can use if he wants to hack into a router successfully. 

There is a risk that a hacker will be able to gain access to a router in minutes if the user has not set a strong password for their router. The hacker can take control of users' router after they have gained access, and even change the settings or install malicious software on users' router after they have gained control. These are all signature signs that users have been hit by a black-hat hacker, as opposed to their more altruistic white-hat cousins. 

Approximately one in 16 internet-connected home Wi-Fi routers can be remotely accessed by attackers using the manufacturer's default admin password. Getting continually kicked off users' home networks can be super annoying, but that's what some hackers will do. A hacker may use a de-authentication attack to target network devices. To do so, a hacker does not even need administrative access to the user router; they only need to find the router and device users' using. They can do this by using a tool such as Aircrack-ng. After doing so, they craft a command that uses the users' router's authentication protocol to deauthenticate users, thus kicking them off the network. 

A Forbes study found that 86% of users never change their default credentials. As default credentials are easily found online, all hackers must do a perfunctory Google search to find the information they need to log into users' routers. If they do, they can change things like the password and SSID. Changing the password will kick users off their network, and changing the SSID will change their network name. They could also hide users' networks entirely after kicking them off and changing the name, making it difficult to get back online. Scammers employ various methods to hack into Wi-Fi networks, exploiting vulnerabilities and poor security practices.

One common technique is brute-forcing Wi-Fi passwords, where hackers systematically attempt numerous password combinations to gain access. Once successful, they can lock users out by changing the password and taking control of the router. Another method involves using the router’s default credentials, often left unchanged by users. Cybercriminals can exploit these factory-set admin passwords to alter router settings, emphasizing the importance of creating a unique password and SSID (wireless network name) for enhanced security. 

Unpatched firmware vulnerabilities also present significant risks. Attackers can exploit outdated software to infiltrate a router's internal systems. For instance, in June 2023, Asus issued critical firmware updates to protect against remote code execution attacks. One of the most severe vulnerabilities, CVE-2018-1160, dating back to 2018, carried a high severity rating of 9.8 on the Common Vulnerability Scoring System (CVSS). 

Furthermore, cybercriminals can execute Domain Name Server (DNS) hijacking by altering a router’s DNS settings and redirecting users to malicious phishing websites. These examples underscore the importance of updating router firmware regularly, using strong passwords, and proactively securing Wi-Fi networks. Understanding the signs of a hacked router is essential for safeguarding users' networks. Altered DNS settings are a major indicator of a breach, as hackers may manipulate these settings to redirect users' internet traffic without their knowledge, potentially launching devastating pharming attacks. 

Users can check their router’s DNS settings in the admin menu to ensure they have not been tampered with. Another red flag is an inability to access the router using the user's admin password. If the credentials no longer work, it could mean a hacker has changed them. In such cases, perform a factory reset immediately and create a new, strong password. Unexpectedly slow internet can also hint at a router hack, especially when accompanied by other suspicious activities. Hackers may exploit users' bandwidth, causing noticeable performance drops. Additionally, strange software or malware on users' devices can result from a router breach, as hackers often use this method to infiltrate connected devices. While malware can spread through various means, its presence alongside other signs of hacking is a cause for concern. 

Monitoring users' networks for unrecognized devices is another critical security measure. Tools like AVG AntiVirus FREE can detect when unfamiliar devices join users' Wi-Fi, issuing alerts that prompt further investigation. While unauthorized devices don’t always indicate a router hack, their presence could lead to one, emphasizing the need for continuous network monitoring. Using reliable security software is vital to protecting users' devices and networks. AVG AntiVirus FREE offers comprehensive cybersecurity features, including real-time malware detection, phishing defence, ransomware protection, and tools to secure users' Wi-Fi networks from potential router hackers. Staying vigilant and equipped with robust security measures ensures a safe online experience.

Hackers can easily carry out this kind of attack even if they do not have administrative access to the user's router; they only need to identify the router and the device that users use to do so. An aircraft-ng tool, which is available online, can be used to accomplish this task. As a result, they craft a command that uses the authentication protocol of the users' router to deauthenticate them, which means they are kicked off of the network once more. The study by Forbes found that 86% of users do not change their default credentials despite being notified about it. 

The default credentials for routers can readily be found online, so it is only a matter of a quick Google search before hackers can discover the credentials they need to access the routers of their targeted victims. In that case, they can change things such as the password and the SSID of the network. By changing a user's password, they will be kicked off their network, and by changing their SSID, their network name will be changed. It's possible that they could also hide the users' networks entirely after they have been kicked off and changed their names, which would make it difficult for them to return to the network. Using a variety of methods, scammers can hack into Wi-Fi networks by exploiting the vulnerabilities and unfavourable security practices that exist. 

There is no doubt that the most common method of hacking Wi-Fi passwords in today's world is through brute-force attacks, which involve scanning many different combinations of passwords too to discover someone's password by scanning all of the combinations simultaneously. When they are successful in taking control of the router, they can lock users out of their accounts by changing their passwords. A second method involves the use of the router's default credentials, often left unchanged by users when they set up the router. These factory-provided admin passwords can be vulnerable to abuse by cybercriminals, highlighting the importance of using a unique password and SSID (wireless network name) for enhanced security when setting up users' routers. 

As a result of firmware vulnerabilities that remain unpatched, there are significant risks involved. There are several ways in which attackers can compromise the internal operating systems of a router by exploiting outdated software. Asus's most recent firmware upgrade for its laptops was released in June 2023, preventing remote code execution attacks against the device. On the Common Vulnerability Scoring System (CVSS), which calculates the severity of vulnerabilities based on their association with security incidents and their impact, CVE-2018-1160, dated back to 2018, had a severity rating of 9.8. A further method of executing Domain Name Server (DNS) hijacking is to alter a router's DNS settings, redirecting the user to malicious phishing sites by altering the DNS settings of a router. 

As a result of these examples, router firmware must be updated regularly, strong passwords are used, and wi-fi networks are carefully secured proactively. Recognizing the signs of a hacked router is crucial for protecting users' networks. Altered DNS settings often indicate a breach, as hackers can manipulate these to redirect users' internet traffic and launch phishing or pharming attacks. Regularly reviewing users' routers' DNS settings in the admin menu can help prevent such risks. Similarly, being unable to access the router with their admin password may mean hackers have taken control. In such cases, a factory reset followed by setting a strong new password is essential. 

A sudden drop in internet speed, especially when combined with other suspicious activity, could point to unauthorized bandwidth usage by hackers. Additionally, unexpected malware or unfamiliar software on users' devices might result from a router breach. Monitoring for unrecognized devices on users' networks is equally important, as these can indicate unauthorized access and potential hacking attempts. 

Investing in robust security tools is a key step in safeguarding users' digital environments. Comprehensive solutions like AVG AntiVirus FREE provide 24/7 protection against malware, phishing, ransomware, and other threats while keeping users' network secure from unauthorized access. Staying proactive with these measures is the best defense for ensuing their online safety.

Chinese Government-Linked Hackers Infiltrate U.S. Internet Providers in 'Salt Typhoon' Attack

 

Hackers linked to the Chinese government have reportedly breached several U.S. internet service providers, according to The Wall Street Journal. Investigators are calling the cyberattack "Salt Typhoon," which occurred just a week after the FBI dismantled another China-backed operation called "Flax Typhoon." That attack targeted 200,000 internet-connected devices such as cameras and routers.

In the Salt Typhoon incident, hackers infiltrated broadband networks to access sensitive information held by internet service providers. Sources close to the matter told WSJ that unlike past attacks focused on disrupting infrastructure, this one seems to be aimed at gathering intelligence. FBI Director Christopher Wray had warned at the Aspen Cyber Summit that China would persist in targeting U.S. organizations and critical infrastructure, either directly or through proxies.

Chinese cyberattacks have been ongoing, but their complexity and precision have escalated, intelligence officials told the WSJ. Earlier this year, Wray described China's hacking program as the largest in the world, surpassing all other major nations combined.

China has denied involvement in these attacks. Liu Pengyu, spokesperson for the Chinese embassy in Washington, accused U.S. intelligence agencies of fabricating evidence linking China to the Salt Typhoon breach.

The WSJ report revealed that investigators are focusing on Cisco Systems routers, though a Cisco spokesperson said there is no evidence of their involvement. Microsoft is also looking into the attack. Lumen Technologies, the parent company of CenturyLink and Quantum Fiber, recently detected malware in routers that could expose customers' passwords but did not specify which ISPs were affected.

Although there's no indication that individual customers’ data was the target, you can take basic precautions:

  • Change your passwords regularly—especially your Wi-Fi router's password.
  • Consider identity theft protection services, which monitor your credit and banking activity.
  • Review your credit reports regularly to catch any suspicious activity.

New Cuttlefish Malware Hijacks Router Connections, Cloud Data Stolen

 

In the ever-evolving landscape of cybersecurity threats, a new menace has emerged: Cuttlefish. This sophisticated malware targets enterprise-grade and small office/home office (SOHO) routers, posing a significant risk to both businesses and individual users alike. 

Discovered by Lumen Technologies' Black Lotus Labs, Cuttlefish operates by infecting routers and creating a proxy or VPN tunnel to stealthily exfiltrate data. By doing so, it bypasses security measures designed to detect unusual sign-ins, making it particularly insidious. One of the most concerning aspects of Cuttlefish is its ability to perform DNS and HTTP hijacking within private IP spaces. 

This interference with internal communications can disrupt organizational workflows and potentially introduce additional payloads, compounding the damage caused by the initial infection. While Cuttlefish shares some code similarities with HiatusRat, a malware previously associated with Chinese state interests, there is no definitive link between the two. Attribution remains challenging, further complicating efforts to combat this threat effectively. 

According to Black Lotus Labs, Cuttlefish has been active since at least July 2023, primarily targeting users in Turkey. However, infections have been reported elsewhere, impacting services such as satellite phones and data centres. The exact method of initial infection remains unclear, but it likely involves exploiting known vulnerabilities or brute-forcing credentials. Once inside a router, Cuttlefish deploys a bash script to collect host-based data and download its primary payload. 

What sets Cuttlefish apart is its adaptability to various router architectures, making it a versatile threat capable of targeting a wide range of devices. Once executed, the malware monitors all connections passing through the router, searching for specific data such as usernames, passwords, and tokens associated with cloud services like AWS and Digital Ocean. Once this data is captured, Cuttlefish exfiltrates it to the attacker's command and control (C2) server using a peer-to-peer VPN or proxy tunnel.

Additionally, the malware can redirect DNS and HTTP requests to actor-controlled infrastructure, enabling further data interception and manipulation. Cuttlefish severely threatens organizations worldwide, allowing attackers to bypass traditional security measures and dwell undetected within cloud environments. Network administrators should take proactive steps to strengthen their defences to mitigate the risk posed by Cuttlefish and similar threats. 

This includes eliminating weak credentials, monitoring for unusual logins, securing traffic with TLS/SSL encryption, and inspecting devices for signs of compromise. Additionally, regular router reboots, firmware updates, and password changes are recommended for SOHO router users to prevent exploitation.  

Cuttlefish represents a significant escalation in cyber threats, underscoring the importance of robust cybersecurity practices and constant vigilance in today's digital landscape. Organizations can better protect themselves against emerging threats like Cuttlefish by staying informed and implementing proactive security measures.

Malware Targets End-of-Life Routers and IoT Devices

 




A recent investigation by Black Lotus Labs team at Lumen Technologies has revealed a concerning trend in cybercriminal activity targeting end-of-life (EoL) routers and IoT devices. The research sheds light on a sophisticated campaign utilising updated malware known as TheMoon, which has quietly grown to infect over 40,000 devices across 88 countries by early 2024.

The primary target of this campaign appears to be small home and small office routers, which are often overlooked when it comes to security updates. Unlike desktop and server computing, where automatic updates are the norm, many IoT devices lack this crucial feature. This oversight leaves them vulnerable to exploitation by cybercriminals.

One of the key findings of the investigation is the emergence of a malicious proxy service called Faceless, which offers anonymity services to cybercriminals for a minimal fee. By routing their traffic through compromised devices, malicious actors can conceal their true origins, making it difficult for law enforcement to track their activities.

According to Jason Soroko, a cybersecurity expert, routers and networking equipment with weak passwords have long been easy targets for cyber attacks. However, what sets this campaign apart is the use of proxy networks to obfuscate command-and-control (C2) traffic, indicating a new level of sophistication among cybercriminals.

The Mechanism Behind The Threat

The malware responsible for these attacks is distributed through a botnet orchestrated by TheMoon. It targets vulnerable EoL routers and IoT devices, infecting them with a loader that fetches an executable file from a C2 server. This file includes a worm module that spreads to other vulnerable devices, as well as a component used to proxy traffic to the internet on behalf of the attacker.

Global Impact: Financial Sector Under Siege

Despite a majority of infected hosts being located in the U.S., the threat extends globally, with devices in 88 countries falling victim to the campaign. The financial sector, in particular, is a prime target for password spraying and data exfiltration attacks, posing significant risks to organisations worldwide.

Recommendations for Defenders

Network defenders are urged to remain vigilant against attacks on weak credentials and suspicious login attempts. Additionally, experts recommend implementing measures to protect cloud assets from communicating with malicious bots and blocking indicators of compromise (IoCs) with web application firewalls.

The advent of this new cyber threat calls for regular security updates and proper maintenance of IoT devices, especially those nearing the end of their lifecycle. Failure to address these vulnerabilities could have far-reaching consequences, as cybercriminals continue to exploit them for financial gain.
