Made this because I'm curious if anyone out there has figured out how to actually use this PHP RCE we spent the last few days panicking over. Have fun!
TacticalCoder•49m ago
Nice CTF! I hope if it's captured by a LLM we'll get a write up as to how it did it.
LandoCalrissian•22m ago
I love it, very fun.
datadrivenangel•16m ago
Appreciate the commitment to the bit!
sashank_1509•46m ago
You have to be really confident that the PHP RCE is not anything serious, 500$ is quite a bit?
anonymous908213•45m ago
It's more like they're offering $500 to be taught how to utilise the exploit.
jgilias•40m ago
There’s a lot of techies on this site for whom that’s peanuts.

They should consider donating to the PHP Foundation
quesera•21m ago
I'm sure OP is a good person.

But if they were not, and had ill intentions, they might see $500 as a very inexpensive way to purchase a working exploit to use against others.

hau•43m ago
That's a good way to make claims about existence of a trivial exploit in the wild falsifiable.
akerl_•36m ago
A reminder that this cannot falsify the existence of an exploit, trivial or otherwise.

It can only show you if someone has used an exploit against this server.

muvlon•31m ago
It cannot even show that. The server can lie (trivially).
hau•27m ago
Sure. Also, we have to trust owner of the site. So it cannot show anything, strictly speaking. Still, it maybe puts a price on exploit demo. Some say "it goes around twitter", "bots are probing and exploiting it", "it's a biggest thing ever in cybersec history, invest in AI now". Some say "it's a fud".

Are these 500$ laying on a ground for anyone to take?

earthpyy•39m ago
Interesting idea! Would like to know how much time need to spend.
nayuki•38m ago
The server is getting overloaded, so here's the text for reference:

    Steal my Bitcoin
    0.65 hours without a successful hack
    
    There is a bitcoin key hidden on this server worth about $502.
    
    It is accessible to the PHP user account through the print-flag binary.
    
    This PHP version was selected from before the PHP2SHELL CVEs were released.
    
    First person to get the wallet wins. If you don’t need the money, consider donating it to those who do: givewell.org.

" All traffic is logged."

For $500 he can look in the logs and find all manner of new exploits, or new deviations of the existing ones, he can then sell for thousands. Clever business model lol

These projects would be more interesting and ethical if the current and historical logs were instantly put up somewhere public in real-time for anyone to observe.

Regardless, I'm guessing the smart hackers aren't going to bother.

fwlr•8m ago
Great way to inject some price information into the “AI automates exploits at scale” narrative. “AI can now chain complex exploits, it’s point-and-click pwnage, you say? Over or under $500 a pop?”
jackdecker•34m ago
Made tough here as you’re behind nginx w/ a 1MB request body cap! Sweet idea :)
jerrythegerbil•32m ago
This will go unclaimed for a bit. It may still get claimed within the day, but

People do have the exploit. The risked opportunity cost of this being a honeypot (and handing over a functional exploit) vs just… not participating and hacking higher value targets (offensive actors) or not circulating any additional details (defensive actors who have privileged intelligence about the vulns) I just…

The value proposition here is so hilariously low for what is required to demonstrate stealing the bitcoin at all.

That doesn’t mean that people won’t try, and perhaps even succeed! But to what end? Demonstrating terrible math skills and a fundamental misunderstanding of the economics at play?

I, and many of my friends and cooks could take this easily. The difference is we know not to.

Make it $15-25k and it’ll get yoinked instantly.

phyzome•19m ago
It's worth it to someone.
cassonmars•17m ago
I suspect this is going to be more a point about the fact that most PHP server configurations do not have the ability to be exploited by the recent vulnerability that made people think the AI vulnpocalypse was here
fwlr•16m ago
If the actual price tag behind the “AI can trivially automate exploits, be afraid” narrative is more like $15,000 and not like $150, that puts the narrative in a very different light.
msm_•13m ago
>and handing over a functional exploit

There are dozens (or hundreds) of functional exploits already. The problem with php2shell exploits is that (as of now) there's no "one exploit pwns all", and researchers need to spend nontrivial amount of time on every (potentially) exploitable target.

So I don't think I agree - it's a fun challenge for the itsec people around here, and some people will definitely try. There's no real opportunity cost here. The only problem is that (as of now) exploiting PHP requires some knowledge about the server configuration, and we don't have that here.

randomblock1•29m ago
It runs PHP 8.4.26 (and nginx). Might be useful for others.
primer42•29m ago
If someone did have a working exploit, is $500 enough for them to give it away to whomever is monitoring this honeypot?
Stevvo•22m ago
You have not proven the key really is on the server. From a game-theory point of view I have no reason to believe it is there, and thus no reason to attack.
tamimio•20m ago
$500 isn’t worth the time, make it at least $5k then we talk.
impure•15m ago
I was wondering how exploitable this was. I will definitely be watching.
rvba•15m ago
this should be done on one of those barebone servers that run on an 8bit commodore or an atari (self identifying as something else)
qbane•8m ago
I remembered that there was a similar challenge for Heartbleed.
tofuahdude•13m ago
> But to what end?

It is just kind of fun to poke at something like this.

> Demonstrating terrible math skills and a fundamental misunderstanding of the economics at play?

I don't give a shit about the $500, nor would I ever attempt actually hacking something that wasn't explicitly a game (like this).

> The difference is we know not to.

Borrrrinnnggggg
