How does one start acquiring skills like these?
mdaniel•11h ago
Practice, and having supernatural perseverance (although probably not in that order)

I'd guess the curriculum is half reverse engineering and half reading any write-ups to see the attacks and areas of attack for inspiration

anthonj•11h ago
I get the feeling these kind of skills are very rare because they fall in the category "understanding and debugging other people code/mess", while most people prefer to build new things (and often struggle to debug their own work).

It takes a lot a passion and dedication to security and reverse engineering to get there.

WalterBright•11h ago
Spending a lot of time debugging code. Eventually, the pattern recognizer in your brain will pick out the bugs. The term for this is "code smell".

For example, when I'd review C code I'd look at the str???() function use. They are nearly always infested with bugs, usually either neglecting to add a terminator zero or neglecting to add sufficient storage for the terminating zero.

jve•9h ago
It is crazy that anytime someone works on application layer and wants to manipulate string, which is a very, very common thing to do when writing application, one has to consider \0 which would be an implementation detail.

How can that language still be so popular?

avar•9h ago
Because whatever language you think should be popular instead is running on a mountain of C code, but the reverse isn't true.
WalterBright•1h ago
The D implementation and runtime library has zero C code in it.
AlienRobot•9h ago
Okay, I want to make a desktop app that runs on Linux. Which language should I use? Java?
rkomorn•9h ago
Some current trendy options would be Kotlin (with Kotlin Multiplatform) or C# (with Avalonia UI).

Edit: I guess I should've at least asked myself if the question was rhetorical.

uecker•9h ago
Whatever you do, please do not use a language that makes it difficult to provide security updates: https://www.debian.org/releases/trixie/release-notes/issues....
AlienRobot•4h ago
My problem with "crossplatform" GUIs that run on Linux is that they aren't made to run on Linux desktop, they are made to run on Android, iOS, Windows, macOS, and finally Linux desktop.

All I want is a menubar, a toolbar, a statusbar, and some dialog windows. I don't want fading transitions when I click a tab.

It's crazy that I'm forced to write header files just to have a menubar.

Zig 1.0 can't come soon enough.

rkomorn•4h ago
Wouldn't Qt or GTK be good for this, then?

Or... https://quickshell.org/ ?

jve•9h ago
That questions is kind of the point I want to make. We live in 2025 and C is still an option for new applications, i.e wrong abstraction layer for application level development.

No doubt there are valid reasons to use it, that is just the state of things they are unfortunately.

uecker•9h ago
The language is just fine. The real question is: Why do people not use a string library that abstracts this away safely?
saagarjha•7h ago
Why does the language not make one?
tonyhart7•6h ago
because at that time, C creator didn't know thing would evolve into the future. after all computer is a new thing
saagarjha•6h ago
Ok, but the question asks why one isn't made today.
uecker•6h ago
There are many string libraries.
saagarjha•6h ago
As you can expect, the answer to your question is the obvious one.
uecker•2h ago
I do not think it is obvious or trivial question. I think the problem is mostly that there is no money for enhancing the C ecosystem and educating people about possibilities. The cooperate money goes into random new things.
WalterBright•1h ago
Oh, people tried. Every C programmer tried it. I tried multiple times. They all failed.

Back when I was musing about what D would be like, I happened across some BASIC code. I was drawn to the use of strings, which were so simple in BASIC. I decided that D would be a failure if strings weren't as easy to use as in BASIC.

And D strings turned out to be better than I'd dared hope!

I proposed an enhancement to C to get much of that benefit, but it received zero traction in the C community. Oh well.

https://www.digitalmars.com/articles/C-biggest-mistake.html

eska•8h ago
Lots of C applications nowadays don’t actually use any of the str functions or null termination.
saagarjha•7h ago
Programming is the consideration of implementation details. When you manipulate strings in C you consider the terminating nul byte just like when you manipulate strings in Python you consider how its stores codepoints or when you manipulate strings in Swift you think about grapheme clusters. There is no free lunch. (Though, of course, you can get reduced price lunches based on the choices you make!)
WalterBright•1h ago
C was popular because, if one is familiar with assembler, it takes about an hour to become adept at programming in it.

It's also an easy language to write a compiler for. At one point I counted over 30 C compilers available for DOS.

Impressive. Feel like finding issues like this in such a large project is like looking for a needle in a haystack
georgemcbay•11h ago
Finding issues in large complex projects is generally easier than smaller projects. More code, more bugs. But its still difficult to find serious issues on the level of a sandbox escape in Chromium just because Google's long-running reward system means lots of people have spent lots of time looking into it, both manually and using automated fuzzer tools.

Back in ye olden days of 2014 I randomly stumbled upon a Chrome issue (wasn't trying to find bugs, was just writing some JavaScript code and noticed a problem) and reported it to Google and they paid me $1,500. Not bad for like half an hour's work to report the issue.

https://issues.chromium.org/issues/40078754

ch33zer•11h ago
I feel like it's the opposite. In a huge project there's bound to be many weird interactions between components, and it's about picking the important/security relevant ones and finding edge cases. In this case the focus was on the interaction between the renderer process and the broker. That forms a security boundary so it makes sense to focus your efforts there - google will pay for such exploits since they can in theory, when combined with other exploits in the renderer process, lead directly to exploits that can be triggered just by opening a web page. So, yes, chrome is a huge project but the list of security-relevant locations to probe actually isn't actually all that long. That's not to diminish the researchers work, it still takes an insane amount of skill to find these issues.
hnlmorg•10h ago
Finding a problem that deserves a bug bounty reward is a very different beast to just finding quirks.

I read from one security researchers somewhere that professionals wouldn’t find enough bug bounty worthy problems in high enough frequency to pay their bills. So they’ll sometimes treat things like this more as a supplement to promote their CV rather than as a job itself.

high_na_euv•11h ago
Kind of life changing money, good to see such rewards
socalgal2•9h ago
the first time I got a bonus that big, $240k, I thought it would be life changing. the gov took $100k in taxes. I paid off my car $20k. then when I really thought about it there wasn’t much I could do.

It was not a down payment on a house in LA/SF/NYC. it was not enough to start a company and hire people. If I’d changed my life style to be like a college student and live with roommates then it might have given me 2-3 years of student lifestyle but I was 34 and not prepared to go back to student lifestyle

To be honest it was super disappointing. Of course getting a $240k bonus is a privilege. My only point was it didn’t change my life like I thought it would.

And, that was 25 years ago. today, even a million ($600k after taxes) in those 3 cities won’t likely change your life. Maybe you could put a down payment on a house or pay for your kids college tho but it not the freedom I thought it would be

gambiting•9h ago
Depends where you live. Where I'm from $240k would buy you a really nice house with lots of land, and you'd have money left over.

>>won’t likely change your life. Maybe you could put a down payment on a house or pay for your kids college tho but it not the freedom I thought it would be

How is being able to put a down paymenent on a house or being able to send your kids to collage debt-free not life changing?

sgjohnson•9h ago
> How is being able to put a down paymenent on a house or being able to send your kids to collage debt-free not life changing?

Because neither of those are going to change your daily life that much? It simplifies a thing or two, but neither of those things are life-changing.

gambiting•8h ago
I can only assume you'd say so if you were able to do either of those things in the first place, so yeah, it doesn't feel life changing. It's like winning a car in a radio lottery when you already had a car - yeah pretty cool, but not life changing.

There's a lot of people who can't even imagine ever being able to put down a deposit on a house or to send their kids to collage debt-free. With an amount of money like that you can go from being trapped in a rent hell forever to actually purchasing your own house. Or you can give your kids the education you want to give them. They are major, life changing impacts. Again, to describe it as "simplifes a thing or two" to me implies that you could do them even without this money in which case yeah, it changes very little.

bearl•2h ago
Property taxes are very high thanks to prop 13. 250k in California is like 30k in states like Texas or Illinois, enough to make it a great year but not life changing.
msh•6h ago
I guess it perspective and where you are in life plus your location in the world, I would have to pay 50% tax on it so well a down payment could be it but I would still have to affort the house.

I have a hard time seeing it as life changing for me, having a decent paying job (not silicon valley developer scale) in a expensive country. Ofc if I was having a low paying career without that many perspective my outlook might differ.

I dont live a place where you pay for your kids being in college so I cant speak for that part.

225k in 2025 dollars is life changing for anyone in the middle class of income. The reason you were unable to do anything with it is because you were already earning too much.
lostmsu•20m ago
Presumably people discovering these bugs are not in the middle class of income.
sgjohnson•9h ago
Depends on where in the world you are. I wouldn't call $250k life-changing-money anywhere developed.

It's "I can probably stop worrying about money for a while" kind of money, not "life-changing" money. Not a whole lot you can buy for $250k. After taxes, that probably doesn't even buy a house.

robin_reala•9h ago
In Sweden, assuming that $125k of that disappears in taxes, it’d leave you with 1.2M SEK. There are currently ~650 properties on Hemnet between 1M and 1.25M. I’d suggest maybe this one in Ödeshög at 1.1M SEK? https://www.hemnet.se/bostad/villa-3rum-odeshog-odeshogs-kom... Not the biggest, but it’s reasonably well done up, comes with 2/3rds of an acre of land, is near a main motorway to get to places, and near the shore of the biggest lake in the country. If you want to take a train then it’s 30 minutes drive to the nearest station on the Stockholm-Copenhagen line.
handsclean•7h ago
Can somebody help me understand why these obviously very stupid takes keep popping up on HN? Is it rich people who genuinely have no idea what anything costs? Is it rich people intentionally being cruel to everybody else? Is it people trying to appear rich by pretending they have no idea what anything costs? Is it a bay area thing, are people just blowing through a literal fortune every year and unaware of their spending problems? Is it children whose ideas about money come from “influencers”?
petcat•7h ago
> Is it rich people intentionally being cruel to everybody else?

If you got a $240,000 bonus in the mid-2000s in tech, that very likely means you were living in one of the tech metros (SF, NYC) and you could expect nearly 50% of that to be paid in taxes (CA/Fed, NY/NYC/Fed). So you take home about $120,000.

It's a windfall of money to be sure. But being in an employment situation where even such a bonus is possible likely means you already have significantly higher costs than the average person. Maybe you'll pay down some student loans and bolster your savings. But this is far from being "rich". High-earners also tend to have high costs of living.

tonyhart7•7h ago
this is just US people culture, its all about money and taxes they should worrying their budget when they have 1 trillion to fund war machine
jynelson•6h ago
tech salaries in the US are high enough that this is approximately 1-3 years of income as a lump sum. more than that, if you got this amount as a bonus you already have stupid money.

of course $140k would be life changing for most people. but OP, and i suspect most of the other commenters, are not in that situation.

socalgal2•2h ago
For the simple reason that it didn’t change my life. Before I received it I thought it would. After I received it, paid taxes , etc. My life didn’t change at all.

It’s a fact that my life didn’t change so it wasn’t a life changing amount of money for me.

Maybe it would be life changing for others. tho at least in sf/nyc/la I suspect it wouldn’t for most people. If I had given it to my sister she’d have used it to pay down her mortgage. her life wouldn’t change. she’d have still had a mortgage and her day to day life wouldn’t have changed at all. My nephew could have used it to pay off his student loans. That would be great but again his daily life wouldn’t have changed

"Decent." was the first word that came into my mind. After a second, I realized that 250,000 USD ist basically 0.00022 % of Alphabet's (Google's?) annual net income [0].

A life changing amount of money for an individual, but nothing more than a small blip on Google's charts. Of course, I'm aware of "budgets" and "departments", and that one simply does not move funds between departments. And while my mind is on the verge of "maybe they should have paid more?", the numbers would mean that even 10x the sum would move the percentage by one decimal. It's wild how much money big corporations have.

I highly applaud the researcher for their tremendous amount of skill and dedication.

brabel•11h ago
How much Alphabet makes is almost irrelevant. The incentive here should be for security researchers. As long as there's enough incentive for security researchers to continue to report the bugs they find (which must be balanced against the potential payment a criminal could get if exploiting the bug, which is not directly correlated to the company's income either, at least not necessarily), the payment is appropriate.
NitpickLawyer•11h ago
To be fair, goog has to pay comparable to other 3rd party brokers, and not necessarily "potential payment by exploiting the bug". Finding an exploit and being able to deploy it for financial gains are two distinct problems, with separate skillsets, risks, etc.

Plus there are some other benefits of disclosing to goog. After you get into VRP you get access to grants & stuff and can basically ask to study a problem and get funded for that effort. Being able to blog about it, pad your experience, etc etc. All while not having to look over your shoulder for 3 letter agencies your whole life :)

sneak•10h ago
You think state intelligence agencies don’t hack whitehats for their 0days?

You know there’s ongoing and plausible efforts by at least 3 organizations to conquer the Earth, right?

MrGilbert•11h ago
> How much Alphabet makes is almost irrelevant.

While I embrace the downvotes, I disagree. From my pov, the amount of money paid should factor in the anticipated risk for your business. If a privilege escalation means that Google takes a massive hit in Ad Revenue, than this should be factored in.

ang_cire•10h ago
> the amount of money paid should factor in the anticipated risk for your business. If a privilege escalation means that Google takes a massive hit in Ad Revenue, than this should be factored in.

Given this exploit, that would probably lower the payout. There are absolutely tons more sandbox escapes in Chromium engine right now (here's a fun list of previous ones, none of which cost them ad rev[1]), and they're not adversely affecting Google's ad revenue. No company is pulling ads because Chrome has a vuln.

This wouldn't even be the kind of reputational hit that something like SolarWinds was.

[1]: https://github.com/allpaca/chrome-sbx-db

UncleMeat•6h ago
Why would it affect ad revenue?

An exploit like this would be abused by somebody who sets up a malicious website to try to take control over somebody's device or otherwise steal secrets from them like keys for cryptocurrencies. These attacks tend to be targeted. Nobody is using an exploit like this to create an ad blocker or even to do ad fraud.

The only risk to revenue here is reputational, and I think that it is likely that the existence of this bug would be less widely known if the bounty program didn't exist and the bug was sold on the black market.

scarab92•11h ago
These types of comparisons are illogical.

There’s little relationship between the net income of a company and what is an appropriate bug bounty, especially a company as diversified as alphabet.

bapak•11h ago
What's your suggestion exactly? Making anyone who can find a bug a millionaire? That's ridiculous. 250k is already insanely high.

You make a bunch money too, should you pay $100 for that taco? It's nothing to you.

pydry•11h ago
Equal to the black market price.

Anything less is an incitement to allow exploits to be used in the wild.

bapak•9h ago
That's a different argument. Price it for its worth, not for my worth.
MrGilbert•11h ago
> You make a bunch money too, should you pay $100 for that taco? It's nothing to you.

Looking at my yearly net income, paying 100$ for a single taco in a year would mean that 0.26% of my net income would go into a taco. Paying 0.1$ for a single taco would make it 0.00026%. According to the consensus in this comment section, that would be pretty gracious. Yes, that's where I'm going with this.

//Edit: Thanks at postflopclarity for pointing out my wrong math.

MrGilbert•9h ago
I was wondering why my math wasn't mathing, but was too busy to earn money at the same time. Thanks for pointing it out, fixed! Now my statement makes way more sense.
TheDong•10h ago
Yeah, assuming the people working at the taco shop aren't very well off the taco should cost $100 for a software engineer, $80M for Jeffrey Bezos, and $4 for someone down on their luck.

If we wanted, we could make this more efficient by giving out free healthcare and housing to people, proportional to their need, and tax $95 from the software engineer, $80M from Bezos, and $0 from someone down on their luck.

Progressive Tacos does sound better than Progressive taxation, and it would probably work better because rich people dodge taxes all the time, but come on, who doesn't want to eat tacos?

We (software engineers) won't have proper empathy for the poor until we go into an apple store and the price tag on the iPhone is "20% of your net worth".

bapak•9h ago

Indeed, one of the great tragedies of life is that this happens. Humans cannot survive without water, yet the median water bill is $80, which is about 1% of the median household's income.

So someone found a way to exploit Chrome. Should Google now cash you out some dividends they got from Ads, YouTube, GCP, Pixel, Android and Waymo so they can really feel that it costs them an arm and a leg?

Suddenly incentives are there to apply as a Chrome developer is more lucrative than CxO position because one can produce bugs for friends to find.

brohee•11h ago
He had a pretty reliable exploit on the most used browser, pretty sure it he could have gotten more tax free on the black market.

In other words, how do they avoid someone playing both sides? "I found an exploit being used by the LEETH4X0R malware [which was in fact created by the guy I sold this exploit to] to steal people's gmail cookies."

You'd have to find out about LEETH4X0R before other researchers, but of course, you'd have a head start.

First, it's not "black market" vs. "non-black market"; most remunerative sales outside of bounty programs are grey-market --- mostly lawful, but all under the table, largely because they're to agencies that are protective of their sources and methods.

The mechanism grey-market buyers have to protect their interests against over-selling bugs is tranched payments. Sellers make much of their returns from bugs on the back end through "maintenance agreements", which both require the seller to keep e.g. the offsets in their exploits current and reliable against new patch levels of the target, and also serve to cut off payment once the vendor kills the bug.

If you sell to both sides, you quickly kill the back end business from the grey market buyers. If you sell to too many or too sketchy grey market buyers, the bug leaks --- vendors see it exploited "in the wild", capture samples, kill the bug; same outcome: tranched payments stop.

This is one reason it can make sense to take a bounty payment that is substantially smaller than what a bug might be worth on the market: you get certainty of payment. Another reason is that the bounty program will only want POC code (perhaps proof of reliability in addition to just exploitability), while the market will want a complete enablement package, which is a lot of work.

The reason you do money laundering is because the source of the funds is illegal. If the source of the funds is legal, just claim it. There are plenty of occupations that get paid in cash and are expected to report it.

The IRS isn't referring suspicious (whatever that means) tax returns to the authorities. What happens if you are a criminal is that the authorities have there attention on you because you are doing illegal things. One angle of attack for them is your finances. That is why money laundering exists.

mike_hearn•10h ago
Selling something to the black market doesn't magically make it tax free. It's almost the opposite. The money is going to show up in your auditable accounts sooner or later, so it's best to pay tax on it, but you'll also have to come up with a fake but auditable story of where it came from, meaning you'll have to engage the services of professional money launderers. They will also take a cut. So, it's like paying tax twice.

Getting paid in cryptocurrency isn't necessarily a dodge either because even if you claim you mined it or something, the authorities have got wise to this a while ago IIUC and will expect to see evidence to back that claim up too.

charcircuit•9h ago
Selling an exploit is not illegal so why bother with money laundering?
XorNot•4h ago
Because the people buying it don't get their money from legal sources, nor engage in legal business activities.

They also have every incentive to make sure you're guilty enough to not go blab to the authorities later, or sell it to someone else.

And since you're trying to be anonymous in this, you aren't going to be getting a regular tax receipt either.

drdec•3h ago
If you did not commit a crime to receive the money, there is no reason for money laundering (at least in the US). The IRS does not care as long as you claim it. You don't need a fancy story or anything, just claim the income.

No, it doesnt typically work that way at all. The tax man just wants to get paid.

I grew up in an area known for people growing cannabis before it was legal. An enormous amount of taxes got dodged through cash land deals, but tons of people just claimed the income under various categories and no one ever came knocking because of that.

Its usually the other way around. If you caught the Fed's eye, then they might try to get you on tax evasion or something. Although, frankly even that was very rare. There are just a lot of very obvious fish to fry.

> pretty sure it he could have gotten more tax free on the black market.

How?

I've been paid by bug bounties (although not that big) and I have no idea how I would find a trustworthy criminal to sell to.

I guess I'd need to find a forum? Unless my opsec is exemplary then I'm risking being exposed. I'd need to vet that the buyer would actually pay me and not just steal it from me. Even if they do pay me, I'd be worried that they'd blackmail me or try to extract something from me. But assuming they're good black-marketeers, I still have to explain to the authorities where this large amount of cash came from.

So how do I go about selling to the black market in a safe way?

Oh, and I don't get to write a blog post about the bug or get my name in front of other researchers and recruiters. That can be worth a huge amount - both in cash and reputation.

NoahZuniga•8h ago

I would consider it a deferred tax. You pay iff you are caught by the tax man with interest (and a potential bonus of a tax free holiday in a state sponsored facility).

From what I understand, they generally require complete reliable exploits. I don't think they generally buy proofs of concept, or exploits that only work some percent of the time. This specific exploit worked 80% of the time, which I'm not sure is good enough for them.

People are fixated, across this thread, on a black market of organized criminals buying vulnerabilities, but for the most part criminals aren't the real alternative market buyers for high-end vulnerabilities, and while people on message boards may incline towards viewing IC and LEO agencies as themselves criminal, I think you'll find a pretty substantial fraction of normal people find supplying IC/LEO agencies as more than just decent; praiseworthy, even.

That thorny ethical issue aside, I'm fond of pointing out that the IC's main alternative to CNE intelligence collection is human intelligence, and the cost of HUMINT simply in employee benefits dwarfs any near-term possible cost of exploit enablement packages; 7 figures is a pittance (remember: most major western governments are essentially benefits management organizations with standing armies).

Even given the seemingly vast sums earned by organized crime, government buyers are positioned to decisively outbid crime over the medium term. It's really early days for these markets.

pyrale•2h ago
Not commenting about the ic/leo part specifically, but there is a pretty abundant body of work on what "normal" people are willing to do, as long as they find a way to rationalize it away. The banality of evil is well documented.

Bugs are "High value" in different ways, you have to find the companies willing to pay highly. Most of the high payers are on bug bounty programs (like hackerone.com) and don't always give you ability to talk about bugs later.

Google is quite unique here, particularly given Chrome is paying easily 10x what Mozilla would for a sandbox escape. Apple is in the middle -- per [1] a "WebContent sandbox escape" would be $50k, but to get $250k on their scale you need to combine that with a kernel bug.

So if you want to optimise for "value", you have to pick the targets that are easier (still not easy, obviously).

Virtually all of Mozilla's income comes from the browser (via the Google search agreement). The vast majority of Google's revenue comes from ad revenue on search, YouTube, and Adsense. Not from Chrome directly. So they had less incentive to reward its security, but did so anyway. And they also do some of the best work in the industry, free, for competitors via Project Zero.

To the extent that meth is a viable substitute for cold medicine you'll have those prices correlating.

But more to your point: the bounty is more similar to an auction. Once you sell the bug to the software producer the black market has no more use of it, assuming it gets fixed.

Supply is constrained, so competition is on the demand side.

On the drug example demand is constrained, if you're the only buyer. So competition happens on the supply side.

matsemann•11h ago
Is there somewhere explaining this bug in terms understandable for someone not dabbling in this?

I don't really understand how this works to "escape the sandbox". Normally it's like a website you visit that get access it shouldn't have. But this talk about renderers and native apis make it seem like it's stuff another process on the computer would do?

Retr0id•10h ago
First you compromise the renderer process via e.g. a bug in the JS engine. But even if you have native code execution in the context of the renderer process, you're still in a sandbox.

The bug in the OP is for the second stage - breaking out of the sandbox.

The referenced `patch.diff` is basically for simulating a compromised renderer.

matsemann•10h ago
Ah, so it's like a two stage rocket, this turns a small exploit into a humongous one?
baobabKoodaa•10h ago
This sounds like a good way to think about exploit chains (though I'm not an expert)
tetha•10h ago
Or an escape room, indeed.

Once you're thinking along the lines of "Alright, if I had some order of flags, I could solve that thing over there. If I knew some kind of weights, I could solve that over there. And if I could find a light bulb I could deal with that over there", you're kinda in the mindset of finding an exploitation chain.

It's just that in the security world, it's more about bad memory accesses, confusing programs into doing the right actions with wrong files, file permissions being weird and such.

Retr0id•7h ago
Sorta, although I wouldn't necessarily call the first exploit "small", it's at least equally important in the overall chain. "Chain" being the more usual metaphor, for this reason.
bialpio•3h ago
Yes. Chrome has multi-process architecture, with renderer processes running in a sandbox. They are the ones that deal with untrusted stuff coming from the Internet and so it is safe to assume that they can be compromised (relatively) easily. The puppet master for all those processes is the browser process, and it is Really Bad if you could exploit it. The described bug presumably does it (note how "sandbox escape" was used in one of the comments), but I'm not competent enough to say exactly how. ;)

Edit: just wanted to riff on your analogy. It is relatively simple to crash/shoot down a rocket, but this exploit gets into the control room and could allow the attacker to see where all other rockets are going & maybe redirect/crash them.

kristianp•7h ago
> The referenced `patch.diff` is basically for simulating a compromised renderer.

The patch.diff part is hard to understand. Surely if you have a compromised renderer, you have effectively full access to the machine already?

Modern browsers have multiple processes with different sandbox policies. The renderer process handles untrusted web content and is heavily sandboxed. The browser process does all the other stuff required to interact with your computer (and is generally much less isolated).

The main browser process treats the renderer as untrustworthy/potentially hostile. A compromised renderer is in the threat model.

Impressive speed on rewarding as well. Around 4 weeks.

Lot of companies will sit for months just to acknowledge your submission.

Google have money to burn though.

I wonder how much the black market would pay for an exploit like that - anyone know?
defraudbah•8h ago
not 250k for sure :)

Google security team is really good, however sometimes things are controversial because certain bugs gets ignored in MS-way which is famous for not paying/not fixing.

Grey market, not black. It's been several months since I've talked to anyone in the space but full-chain reliable quiet Chrome exploit packages were high six figures, with discussions starting about bugs reaching 7 figures imminently, and the people I talked to might have been talking that down (or talking it up).

Again, remember that grey market payouts are tranched, so you could get 3x more than Google would pay, or you could get 0.5x, and for much more work.

Does this mean engineers of Google can't fix it?
saagarjha•7h ago
No, it was fixed after it was reported.

I didn’t get anything for my JavaScript recursive reference failure defect report a decade ago, but then it also wasn’t a sev1 security compromise defect either.

Of note, this is a logic/timing bug, and Rust would not have prevented this.

Although seeing these bugs fixed and getting rewarded for finding them is great, I still think that Microsoft's idea of virtualising the entire browser process was genius. It also feels better than any "lockdown"-like mode that maybe just disables some JIT engine or two.

I'd really like that on both Linux and macOS.

Are there people who work full time from income on bug bounties?
landr0id•4h ago
Yes. There are plenty of folks who submit to the company I work for who live in regions of the world that are extremely low cost of living/salary (in USD terms) and most BB programs pay out fixed USD rates. It can be very lucrative.

To add to the sibling comment, there are also many different ways of making a living doing this stuff:

* You can find killer clientside bugs where the bounty will cover a year's worth of compensation (bear in mind you'll get maybe 1.5 of these payouts a year on your own if you're good but replacement-level)

* You can find these kinds of bugs and work with brokers to sell them to grey-market buyers along with enablement/implants --- more development work, a little more market risk.

* You can find smaller, easier bugs (serverside, web bugs) that get nothing resembling these kinds of payouts but are much easier to find, and make good money on volume. This is a much more common way of making a living on bounty payments.

This seems harder and riskier than a full time wage - almost like a salesman who makes money from commission.
tptacek•3h ago
The salesperson earning much of their annual take-home from variable compensation is one of the most common white collar jobs there is.

I'm highly skeptical this level of bug bounty would be sustainable by whatever company ends up buying Chrome after DOJ forces it to be divested.
