It is not on daily basis a humble Wi-Fi router makes an look within the halls of Congress. However that is precisely what occurred on March 5 when Rep. Raja Krishnamoorthi, a Democrat from Illinois, held up a TP-Hyperlink router and mentioned, “Don’t use this.”
Krishnamoorthi has been urging a ban of the routers for months in response to a number of China-backed cyberattacks final yr. Investigators on the Commerce, Protection and Justice departments all opened probes into TP-Hyperlink routers in 2024 because of ties to Chinese language cyberattacks.
These departments are weighing a possible ban on the sale of TP-Hyperlink routers, The Wall Road Journal reported in December. Together with Rep. John Moolenaar, a Republican from Michigan, Krishnamoorthi spurred the investigation over the summer time with a letter to the Division of Commerce calling for a right away ban.
A possible ban is extra concerning the firm’s hyperlinks to China than particular safety points which have been publicly recognized, in line with cybersecurity researchers I spoke with.
TP-Hyperlink was based in 1996 by brothers Zhao Jianjun and Zhao Jiaxing in Shenzhen, China. In October final yr, it moved its headquarters to Irvine, California, two months after the Home introduced an investigation into the corporate. The corporate informed CNET it had beforehand operated twin headquarters, in Singapore and Irvine.
Within the Home’s Choose Committee on China listening to, Rob Joyce, former director of cybersecurity on the Nationwide Safety Company, additionally informed the committee that TP-Hyperlink routers are a risk to US cybersecurity.
“We have to all take motion and change these gadgets so they do not change into the instruments which are used within the assaults on the US,” Joyce mentioned.
In a press release to CNET, TP-Hyperlink President Jeff Barney mentioned, “Witnesses on the listening to didn’t current a shred of proof that TP-Hyperlink is linked to the Chinese language authorities and we aren’t.”
TP-Hyperlink has change into more and more dominant within the US router market for the reason that pandemic. Based on the Journal report, it grew from 20% of whole router gross sales in 2019 to round 65% this yr. TP-Hyperlink disputed these numbers to CNET, and a separate evaluation from the IT platform Lansweeper discovered that 12% of dwelling routers at present used within the US are made by TP-Hyperlink.
“Folks anticipate there to be some smoking gun or one thing in these gadgets from Chinese language producers, and what you find yourself discovering is the very same issues in each machine. It is not just like the Chinese language gadgets are obviously insecure,” Thomas Tempo, CEO of cybersecurity agency NetRise and a former safety contractor for the Division of Vitality, informed CNET. “That is not the danger. The danger is within the company construction of each Chinese language firm.”

In my conversations with TP-Hyperlink representatives, they’ve repeatedly distanced themselves from ties to China.
“TP-Hyperlink has a safe, vertically built-in and US-owned worldwide provide chain,” a TP-Hyperlink consultant informed CNET. “Practically all merchandise bought in the US are manufactured in Vietnam.”
Even so, the US authorities seems to see TP-Hyperlink as a Chinese language entity. In August, the Home Choose Committee urged an investigation into the corporate.
“TP-Hyperlink’s uncommon diploma of vulnerabilities and required compliance with [Chinese] regulation are in and of themselves disconcerting,” the lawmakers wrote. “When mixed with the [Chinese] authorities’s frequent use of [home office] routers like TP-Hyperlink to perpetrate intensive cyberattacks in the US, it turns into considerably alarming.”
Requested for remark, a TP-Hyperlink consultant informed CNET, “Like many client electronics manufacturers, TP-Hyperlink Programs’ routers have been recognized as potential targets for hackers. Nevertheless, there isn’t any proof to counsel our merchandise are extra weak than these of different manufacturers.”
CNET has a number of TP-Hyperlink fashions on our lists of the greatest Wi-Fi routers and can monitor this story intently to see if we have to reevaluate these selections. Although our analysis of the {hardware} hasn’t modified, we’re pausing TP-Hyperlink routers as our high advice till we be taught extra.
A ban is extra about TP-Hyperlink’s ties to China than a identified technical difficulty
The cybersecurity specialists I spoke with all agreed that TP-Hyperlink had safety flaws, however so do all router firms. It’s unclear whether or not the federal government has discovered a brand new difficulty that might result in a possible ban on TP-Hyperlink gross sales.
The Wall Road Journal article cited federal contracting paperwork that present TP-Hyperlink routers bought by businesses from the Nationwide Aeronautics and Area Administration to the Protection Division and Drug Enforcement Administration.
The potential ban comes at a time in Washington when there may be rising bipartisan assist for extracting Chinese language merchandise from US telecommunications. In an assault revealed in October dubbed Salt Hurricane, Chinese language hackers reportedly broke into the networks of US web suppliers like AT&T, Verizon and Lumen, which owns CenturyLink and Quantum Fiber.
“Vulnerabilities in embedded gadgets aren’t distinctive to anyone producer or nation of origin,” mentioned Sonu Shankar, chief product officer at Phosphorus Cybersecurity. “Nation-state actors regularly exploit weaknesses in gadgets from distributors worldwide, together with these bought by American producers.”
Brendan Carr, Trump’s choose for Federal Communications Fee chairman, mentioned in an interview with CNBC {that a} current intelligence briefing on the Salt Hurricane assault “made me need to principally smash my cellphone on the finish of it.”
“In some ways, the horse is out of the barn at this level,” Carr mentioned. “And we want all arms on deck to attempt to tackle this and rein this in.”
TP-Hyperlink hasn’t been linked to the Salt Hurricane assaults, however it does present the present temperature for perceived threats from China.
The federal government could have recognized a TP-Hyperlink vulnerability, however we don’t know for positive
A number of of the cybersecurity specialists I spoke with consider it’s probably that intelligence businesses have discovered one thing with TP-Hyperlink that warrants a ban.
“I feel this comes from a deeper intelligence throughout the US authorities. Often this occurs earlier than the knowledge turns into public,” Guido Patanella, senior vice chairman of engineering at Lansweeper, informed CNET.
“I feel it is past political,” Patanella added. “It could possibly be both an deliberately set {hardware} flaw or it could possibly be from a firmware perspective. That is often a black field evaluation and it often would not get shared, as occurred with Huawei.”
In 2019, Trump issued an government order that successfully banned US firms from utilizing community tools from Huawei, one other Chinese language firm that got here beneath hearth over nationwide safety issues.
Tempo, the NetRise CEO, informed me he thinks it’s probably that there’s a “zero-day” vulnerability in TP-Hyperlink gadgets — a time period that refers to a hidden flaw during which there have been zero days to repair it — however he was fast to level out that there’s no proof to again that up.
“However no less than that declare relies in some type of actuality that we’re conscious of that exists, which is that the PRC (Folks’s Republic of China) is concerned in each Chinese language company. And that is plain,” Tempo mentioned.
TP-Hyperlink has identified safety flaws, however so do all router firms
A TP-Hyperlink consultant pointed us to the Cybersecurity and Infrastructure Safety Company’s listing of Identified Exploited Vulnerabilities. TP-Hyperlink has two of those occasions catalogued, in comparison with eight for Netgear and 20 for D-Hyperlink; different fashionable router manufacturers like Asus, Linksys and Eero have none.
By this measure, TP-Hyperlink isn’t distinctive in both path, however which may not be all that helpful of a measure.
“We have analyzed an astonishing quantity of TP-Hyperlink firmware. We discover stuff, however we discover stuff in the whole lot,” mentioned Thomas Tempo, CEO of cybersecurity agency NetRise and former safety contractor for the Division of Vitality.
“The issue with the CISA KEV [list] is, if the whole lot’s on the listing, how good is that listing?” Tempo added. “Mainly, each telecommunications machine on the planet has no less than one vulnerability on the CISA KEV. It is a large drawback that there aren’t nice solutions to.”
There have additionally been a number of cybersecurity studies which have singled out TP-Hyperlink particularly. Probably the most high-profile one got here in October when Microsoft launched particulars on a password spraying assault it had been monitoring for over a yr. In this kind of assault, hackers use a single frequent password to entry a number of accounts.
Microsoft referred to the assault as “nation-state risk actor exercise” and mentioned TP-Hyperlink made up many of the routers used.
In Might 2023, Verify Level Analysis additionally recognized a firmware implant in TP-Hyperlink routers linked to a Chinese language state-sponsored hacking group. On this case, the marketing campaign focused European international affairs entities. Nonetheless, the researchers emphasised that the assault was written in a “firmware-agnostic method” and wasn’t designed to use TP-Hyperlink particularly.
“Whereas our evaluation targeted on its presence in modified TP-Hyperlink firmware, earlier incidents present that comparable implants and backdoors have been used on gadgets from numerous producers, together with US primarily based,” Itay Cohen, one of many authors of the Verify Level Analysis report, informed CNET.
“The broader implication is that this implant isn’t about focusing on a selected model — it’s half of a bigger technique to use systemic vulnerabilities in web infrastructure.”
Cohen mentioned he doesn’t consider a TP-Hyperlink ban would enhance safety a lot. As I heard from different researchers, the safety points which have been recognized aren’t distinctive to at least one firm.
“The vulnerabilities and dangers related to routers are largely systemic and apply to a variety of manufacturers, together with these manufactured within the US,” Cohen mentioned. “We don’t consider that the implant we discovered was identified to TP-Hyperlink or was knowingly inserted as a backdoor to their merchandise.”
Is it protected to make use of a TP-Hyperlink router?
There are actual dangers related to utilizing a TP-Hyperlink router, however some stage of threat is current it doesn’t matter what model of router you employ. On the whole, cyberattacks tied to Chinese language actors have focused suppose tanks, authorities organizations, nongovernment organizations and Protection Division suppliers, in line with the Journal’s reporting.
“I do not suppose that the common individual goes to have this huge goal on their again,” Tempo informed CNET. “They have a tendency to go after the issues they need to go after.”
That mentioned, these sorts of assaults are sometimes indiscriminate, with the aim of making a sequence of nodes between contaminated routers and hackers.
“This implies common customers are liable to being focused as a part of a broader assault marketing campaign, even when they aren’t individually focused,” mentioned Cohen, the Verify Level Safety researcher.
How you can shield your self in case you have a TP-Hyperlink router
To maintain your community protected and safe, it is best to observe the identical steps whether or not you’ve got a TP-Hyperlink router or every other model. Right here’s what specialists advocate:
- Hold your firmware up to date: One of the crucial frequent methods hackers entry your community is thru outdated firmware. TP-Hyperlink informed us that clients with TP-Hyperlink Cloud accounts can merely click on the “Verify for Updates” button of their product’s firmware menu when logged into the TP-Hyperlink app or web site. It’s also possible to discover the newest updates in TP-Hyperlink’s obtain middle.
- Strengthen your credentials: If you happen to’ve by no means modified the default login credentials in your router, now’s the time to do it. Weak passwords are the reason for many frequent assaults. “Gadgets utilizing default or weak passwords are simple targets,” Cohen informed CNET. “Default or easy passwords may be simply brute-forced or guessed.” Most routers have an app that allows you to replace your login credentials from there, however it’s also possible to sort your router’s IP tackle right into a URL. These credentials are completely different out of your Wi-Fi identify and password, which also needs to be modified each six months or so. The longer and extra random the password, the higher.
- Think about using a VPN service: For an added layer of safety, a digital personal community will encrypt your entire web site visitors and stop your web supplier (or anybody else) from monitoring the web sites or apps you’re utilizing. Yow will discover CNET’s picks for the greatest VPN providers right here.
- You could have router selections: In CNET’s testing, TP-Hyperlink routers have constantly ranked as among the top-performing routers to select from. If you’re available in the market for a brand new router however feeling further cautious, CNET names a few different nice choices to select from right here.
