EXPERT Q&A — There may be rising deal with the vulnerability of undersea cables — a important infrastructure which is essential to a lot of worldwide communications. They’ve been broken in numerous hotspots all over the world, with some incidents pointing to nefarious actors. One other menace past bodily injury is the potential for intrusions and tapping, particularly on the subject of U.S.-linked cables and China. Central to this difficulty is the dominance of Chinese language corporations in making, sustaining or repairing the cables linked to the U.S. In July, the chairs of three Home committees wrote to the CEOs of Google, Meta, Microsoft, and Amazon to report on how uncovered cables are to China on this approach.
The Cipher Transient spoke with Beth Sanner, former Deputy Director of Nationwide Intelligence at ODNI, to evaluate the Chinese language menace to undersea cables and why it’s so difficult for the U.S. to mitigate the danger. Our dialog has been edited for size and readability.
The Cipher Transient: What’s the fear right here? What is the sort of nightmare state of affairs? Why is the Congress asking the tech corporations to report again on this stuff?
Sanner: A lot of our communications flows by way of these cables, together with encrypted categorized info. There may be a number of stuff that’s essential. Not all of it’s categorized, after all — simply on a regular basis supplies from monetary transactions or individuals’s connections to the web. So there are clearly a number of the explanation why we must always contemplate undersea cables as a part of U.S. important infrastructure. However that important infrastructure, in contrast to most of what we discuss, is not solely in the USA. Actually, all of that is exterior the USA, and never even all of that connects on to the USA. The vulnerability is so world as a result of we’re sending monetary transactions between the USA and Singapore, for instance, and even for China.
The Cipher Transient: There is no scarcity of points the place the identical considerations apply when it comes to China having a hand in areas of our lives that contain information seize and information assortment. Right here, it’s extremely laborious to see how A, one would know precisely the place that Chinese language hand is, and B, as an instance considered one of these corporations comes again and says, nicely, we expect that possibly a Chinese language entity does some upkeep work. I think about it is fairly laborious to instantly shift gears for Meta or Google or the opposite corporations to say, okay, we’ll simply instantly have one other upkeep firm that is not Chinese language.
Sanner: Proper, so let’s break that down a bit of bit. First, the best way that info flows over these strains, it’s extremely laborious to limit the place issues go. The messaging visitors tends to go on the strains which have the least quantity of resistance and essentially the most effectivity. So, your information will be going nearly anyplace.
And we all know that the FCC goes to be assembly in August and contemplating, and I might wager that they will, banning any Chinese language gear in cables that hook up with the USA. (Editor’s Observe: On August 7, 2025 the FCC banned the usage of gear and companies from Chinese language corporations on its “Lined Listing” and different companies’ lists of entities deemed nationwide safety threats on any future undersea cables connecting to the U.S.)
That implies to me that there may be an issue that we do not find out about. Is there the usage of Chinese language parts even contained in the cables connecting to the USA? I can let you know all cables connecting to U.S. navy installations all over the world, that I do know of, although there might be exceptions, I feel are dealt with by the American firm referred to as Subcom, which is owned by Cerberus, which Steve Feinberg, the now Deputy Secretary of Protection, was the co-CEO of till very lately.
However we simply heard that Microsoft, of their cloud computing, with the U.S. DOD is utilizing Chinese language engineers for a part of the upkeep of the cloud. And so it makes you marvel, I suppose it is potential that persons are doing silly issues like utilizing items like switching gadgets. These switching gadgets direct the transmission of the sunshine, or they may shut it down. What if these parts, similar to parts that we lately heard have been embedded in photo voltaic panels within the grid in Texas, are transmitting again or someway managed by China? I do not know, that is past my engineering functionality, however I might say that we’d have an issue there.
After which the third downside I might say is that this concept of the repairs, as a result of most cables which can be reduce are unintentionally reduce. But when we depend on China for repairs, then one thing will be inserted in that course of to faucet that exact cable. And that may go on then indefinitely.
The Cipher Transient: We have been simply speaking about among the reporting that among the huge suppose tanks have accomplished, CSIS particularly, that implies that whereas Chinese language corporations and entities will not be the market leaders on the subject of the development of those cables which can be reaching U.S. shores, they’ve a giant chunk of the market, two corporations particularly, on the subject of restore work.
Again to the primary query, out of your intelligence group background, how worrisome is that?
Sanner: Properly, that’s the capacity to insert a faucet mechanically. That is how it’s accomplished. So, any time a Chinese language ship restore operation is occurring by the corporate that is a subsidiary of Huawei or the opposite firm, all of those corporations report again to Beijing and definitely will be not even compelled, simply instructed to do this mission. So I contemplate that a completely excessive danger.
Now, my understanding is that Cerberus and Subcom are starting a fleet of restore ships. They’ve two ships on this fleet of cable restore ships, in accordance with one article that I learn in Reuters. That is all I do know is open supply, after all. And so I feel the USA understands this weak point. However my understanding, too, is that these Chinese language ships have repaired 25% of the cables which have been reduce. So once more, our info will be on strains which can be exterior of our ecosystem. And I’ll say that, when it comes to the overarching difficulty right here, it is a personal sector endeavor, proper? There are not any authorities owned cable strains. Not likely. It is a personal sector deal. And so that is the place public personal partnership must work.

The Cipher Transient: Your level about American corporations now getting concerned within the restore work, the Home committee that appears at China and nationwide safety points has been so aggressive in the whole lot from TikTok to all these different issues. Undersea cables have been round for some time. You’d suppose it could not have taken this lengthy to do what you simply stated, which is have American corporations exit and do that in the event that they’re so nervous about it. Any ideas as to why?
Sanner: Anyone’s received to pay for the contract to have it as a result of I feel we have simply counted on the personal sector to do that.
The Cipher Transient: After which the opposite query, are we at a stage now with this kind of factor that if the corporate has any ties to Beijing that one needs to be nervous about it?
Sanner: I do suppose that it is true that something that is linked to China is dangerous. We all know that China’s inside our important infrastructure in the USA, proper? And they’re there to pre-position themselves in case of struggle, or possibly whilst a preemptive factor to stop us from interfering in, for instance, a Taiwan invasion.
So I might suppose that undersea cables are not any completely different on the subject of the USA, however I feel we’ve a broader difficulty of the potential of a concerted effort to chop cables all over the world as a result of there’s little or no we are able to do to stop that besides in very outlined geographic areas. So NATO final 12 months arrange a working group targeted on undersea cables and the safety of them. And so they’re engaged on growing methods like AI methods and distant sensing as a way to monitor what is going on on and likewise to make use of that sensing to trace the actual ships that they suppose are problematic, both from the grey tankers or these cargo ships that they know are problematic. We would wish to copy that within the Pacific. And who’s going to do this? We do not have a NATO within the Pacific.
And so I feel that that may be a actual problem for us down the road. We won’t simply consider this as a geographic downside that begins and ends with what connects to the USA. I hold seeing this. It is like, nicely, we do not care what occurs in Ukraine or we do not care what occurs, we’re right here in America. That simply doesn’t work anymore. Our geography is great and it protects us from some issues, however on the subject of cyber and area and undersea cables, communications, that isn’t sufficient. So we’ve to suppose globally.
