A widespread concern is what would happen to Dutch weapon systems if the Americans were to withdraw completely as an ally. For example, Dutch F-35 aircraft are dependent on American software updates. Yet, Tuinman isn't particularly worried about this.

"The F-35 is truly a shared product. The British make the Rolls-Royce engines, and the Americans simply need them too." And even if this mutual dependency doesn't result in software updates, the F-35, in its current state, is still a better aircraft than other types of fighters.

If you still want to upgrade despite everything, I'm going to say something I should never say, but I will anyway: you can jailbreak an F-35 just like an iPhone. (Crack it with your own software, ed.)

Help, how do I unlock the bootloader

[–] DivineDev@piefed.social 30 points 3 weeks ago (2 children)

During startup, press the fire missile and eject buttons at the same time for 20 seconds

[–] SayJess@piefed.blahaj.zone 11 points 3 weeks ago

What??? In earlier versions, we had to lift a couple of legs on the chips, a 50cm bodge wire, and finally shorting a capacitor while booting. Finally the write protection disabled, which allowed one to flash an older BIOS that allowed usb booting. The major downside was that it was a tethered jailbreak. But we made it work…except for the fly-aways.

[–] stupidcasey@lemmy.world 7 points 3 weeks ago* (last edited 3 weeks ago)

I'm having issues with this step, I can't seem to hold the eject button for the full 20 seconds I keep getting forcefully ejected to the boot screen.

[–] Sabata11792@ani.social 11 points 3 weeks ago* (last edited 3 weeks ago) (5 children)

Flashing failed 5 minutes in, and now an upside down jet with a big yellow ! coming out of the belly is on the screen. Did I brick my F-35 or is it recoverable?

[–] MatSeFi@lemmy.liebeleu.de 12 points 3 weeks ago

Depends on your altitude..

imagine flying a jailbroken fighter plane that gets an over-the-air update that bricks the controls

just get the gripen

[–] Soup@lemmy.world 34 points 3 weeks ago (2 children)

Something tells me fighter planes don’t get updates from anything other than a computer plugged directly into them.

[–] boonhet@sopuli.xyz 12 points 3 weeks ago* (last edited 3 weeks ago)

In production since 2006 and of course they were designing the things earlier than that, so....

Wouldn't be surprised if it's like some cars of the late 90's and early 00's and you need a computer with an RS-232 port to connect to a multiplexer of some sort that connects to the plane

E.g to get full dealer level access to old Mercedes cars, you'd need one of these:

And a laptop with RS-232 running Windows XP (can be on a VM)

[–] RememberTheApollo_@lemmy.world 8 points 3 weeks ago (1 children)

That would seem like an awful idea that would be a dangerous security risk to the fighter.

So they probably did it anyway.

[–] FauxLiving@lemmy.world 12 points 3 weeks ago* (last edited 3 weeks ago)

Well, let me be the one to surprise you and tell you that this is exactly how software and encryption keys are loaded onto the aircraft.

At no time would any combat aircraft have an operating system which even has the capability to receive software updates wirelessly, that would be an incredible vulnerability during wartime.

It requires a specific device that looks like it was made in the 1980s and deletes itself if it is bumped too hard and this device has to be directly connected to NSA controlled infrastructure in order to be loaded with any updates. The resulting material is loaded onto the device and physically carried by an Airman in the wing's comm squadron and they are escorted by at least one other service member from the secure terminal where it was loaded directly to the aircraft.

It's uploaded via internal connections (which may or may not look to be from the 80s) which are accessed by a maintenance hatch on the belly of the plane. Once the hatch is closed, if it is opened again at any point the aircraft will dump all of the key material and the resulting party will have a lot of paperwork and counseling to deal with and some other set of airmen will have to repeat the entire process all over again.

This has to be done for pretty much every flight, the aircraft cannot even start without this package of key materials and software. This process is fairly standard and used on a lot of equipment, as most equipment needs keying materials to function due to all of the datalink and/or telemetry systems.

It is likely that the Secretary of Defense was referring to their understanding of how this system operates and how they have scientists and engineers and the resources to reverse engineer any components. They have intact and working copies that they can tear apart and none of these systems are magic, they're just secret and obtaining an intact war plane to reverse engineer is incredibly difficult in normal times. The Dutch have plenty of intact war planes to study.

"ATTENTION! Your jet has been hacked by MilitaryGod Tech Team[LOL]. Your radios and controls have been disabled. Do not attempt to eject. Please send 10 bitcoin to wallet 214d93120cd3192ea019ab03928f1fa03 immediately to unlock your controls. If we do not receive payment in 15 minutes, all weapons onboard will be launched at nearby friendly targets. Thank you for your prompt attention to this urgent matter. Have a nice day!"

tbf, that can happen without jailbreaking

And here I thought the military would want their stuff to work without software updates and be open source.

[–] Humanius@lemmy.world 27 points 3 weeks ago* (last edited 3 weeks ago) (17 children)

The military wants the best equipment, and currently in terms of specs that is the F-35.

That comes with a dependence on the United States, which at the time of purchasing these jets was not considered to be a particular concern because America is a good ally and a part of NATO.

Following Trump's re-election and antics over Greenland, that calculation is now different. It might not be worth it to buy new F-35s at this point (though Germany seems to be considering it still), but the Dutch army has pre-existing F-35s which we should be able to use even if America doesn't want us to for whatever reason.

At this point for the purchase of new jets we really should be looking at the new Eurofighter though, imo

Please keep buying our jets bro

We spent $1 trillion to make them bro, we need these to work bro

We'll iron out all he bugs, trust us bro

It's the best jet ever made bro, it's killed so many Palestinians and Iranians bro

Upon hearing this news I ordered a F-35 from Ali Express but they sent me a J-35 instead. Does the jailbreak still work on this device or am I stuck with the stock software? What's the character for landing gear again?

[–] regedit@lemmy.zip 11 points 3 weeks ago

The future is vibe coders getting jobs creating plausible, yet fundamentally broken firmware updates to OTA brick F-35 fighter jets.

Come attack us, I dare you. Jack here used his prompting skills to package some Stack Overflow RUST code into Golang binaries that another prompt converted into XHTML so another prompt could compile it into a Bash script to fix the bug in flight controls. Come within 50-nautical miles and we'll OTA update your plane so hard you wish we fired missiles at you!

Well yeah, nerds in their basement with a passion for repairability figured out how to jailbreak iPhones, of course nation-states with a passion for ~~killing others~~ protecting their global interests are gonna figure out how to jailbreak their war machines

[–] metermatic26@lemmy.world 7 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

I’ve been working in the Dutch tech sector for decades. My general opinion about the culture of Dutch governmental institutions, including Defense, is one of neoliberalism and technological opportunism.

Public officials are completely ignorant about technology, yet misuse technology to advance their careers by starting megalomanic IT-projects, meant as nonsensical solutions to help realize highly unlikely business cases, that will only be realized (maybe) years after they’d handed over the reigns.

All of this has caused governments to become highly digitized, with large pools of IT-‘professionals’, yet barely able to maintain and develop the digital infrastructure they built up, because of a catastrophic shortage of tech-savy leaders and actual experts.

The reason I mention this, is because Dutch public officials are generally both highly techno-optimistic as well as highly techno-ignorant. Its not uncommon to see them making claims that sound misguided or downright false to anyone who’s anyone.

My take is that Tuinman likely shared his comment in an attempt to comfort the public, but that it betrays his fundamental lack of understanding about the digital infrastructure that makes up the F35. And if Tuinman is being fed this sort of information by his subordinates, then I’m worried that the experts at Defense might not actually understand the infrastructure themselves either.

The risk in all of this, is that Defense and the political establishment might be lulling themselves into a false sense of security, by underestimating the risks. Sure, you can jailbreak software, but many of the F35’s capabilities still require live access to the American intelligence infrastructure. Without that access the F35, knowing there is no European alternative, you are left with a fundamentally broken plane.

The racist sack of shit, Hegseth, will have his sick fucknut friend, Doug Wilson (Christian Nationalist), bless each F-35. I hope one of you posts the Pentagon Prayer service given by the fucking lunatics.

If I had the F-35 in my inventory, I would hire a bunch of hackers to prepare the aircraft's software for the just in case moment.

[–] MalReynolds@slrpnk.net 6 points 3 weeks ago (5 children)

Possible sure, easy unlikely, knowing you got all the backdoors (for allies), nigh impossible. Only way to be sure is to clean room it from the ground up, not jailbreak.

The only thing that is certain, is that the logistics chain of the F-35 can easily break down. It is best for the EU to rely on a chain that is fully within their custody.

[–] Overspark@piefed.social 5 points 3 weeks ago

Tl;dw is that sure, the US could withhold software updates and sure, NL could do their own software thing, but there is a whole intelligence software thing too that makes it harder. And ultimately if the US stops supplying new parts the existing planes are quickly dead in the water anyway. So it's a short-term solution at best.
