It's the worst outcome for everybody. Programs are flooded with low quality & low impact reports that burn time and budget for little to no real security gain, and experienced bug hunters end up waiting months to _maybe_ get their High and Critical impact reports looked at and paid out

Agreed, the marketing was _always_ quantity over quality focused. It was a foot-gun waiting to go off from the start

Hot take, Bug Bounty is not a field for beginners, and should never have been promoted that way. The root cause of 90% of the problems programs face can be attributed to this. It's time we ditch this old framing, and instead promote Bug Bounty as a field for professionals.

If I were a Bug Bounty platform in 2026, I'd implement two policies _right now_: 1. Require KYC for accounts before allowing bounty submissions 2. Take care of hunters who are consistently reporting Critical impact issues And one more for free, stop promoting BB as a beginner friendly discipline

If I were a Bug hunter in 2026 (oh wait I am!), I'd implement two policies _right now_: 1. Stop reporting Low, Medium and speculative bugs 2. Spread your efforts across a large number of programs / platforms And one more for free, bank as much as you can now, the future of BB is going to be wild!

If I were running a Bug Bounty program in 2026 I'd implement two policies _right now_: 1. Stop paying for Low and Medium impact bugs 2. Prioritise triage for known good bug hunters to your program (rep, impact, bounty sum etc.) And one more for free, use the ban hammer liberally and often.

The Vulnpocalypse Is Repricing the Bug Bounty Economy
The surge in AI-powered vulnerability reports is driving down bug bounty prices, and that could spell trouble for independent researchers.

My first daughter would have been 8 today. Instead of joy and happiness on her birthday, my family live with a deep sadness on this day. Chloë was stillborn as a result of Edwards Syndrome. I miss her so much, a beautiful life that could have been but was never given the chance. I love you baby, Dad

If you run a Bug Bounty program (or platform) now might be a good time for you to publish the average time to triage for various issue severities. There are a _lot_ of disgruntled hackers out there at the moment who are waiting weeks / months for a program to even perform a first look at a report!

Bug Bounty is remotely debugging last year's unreliable n-day using last week's reliable n-day... which I can't report because the vendor needs "time to patch." 🤦

There needs to be consequence for those hackers that waste triage resource and benefit for those who provide clear, easy and possibly automatable reproduction steps. The first platform that offers me as a proven, experienced and reliable bug hunter preferential triage wins my loyalty in 2026.

Alex Chapman @ajxchapman.bsky.social · 14/04/2026
100%, this is not a triager problem. To triage efficiently for an ever increasing number of (both human and automated) hackers would require a continued _huge_ investment in triage workforce, and even then would be unsustainable. If anything, it's a hacker problem.

Alex Chapman @ajxchapman.bsky.social · 14/04/2026
2026 and Bug Bounty triage is broken. This has on the horizon for years, even without LLM pressure, but it still seems to have caught _every_ major platform and large private program by surprise.

☝️ Triage times across all platforms have sky rocketed. In the before times triage of 2+ days for higher impact bugs was unusual, now we are often into weeks. I really like @intigriti.com's approach, if you are reporting valid bugs you see no difference, if you are reporting crap you get penalised.

Submission limits (open submissions)
Updated yesterday
To keep response times fair for everyone, Intigriti may limit how many submissions you can have open at the same time.

 

What is a submission limit?
 

A submission limit restricts how many submissions you can have open simultaneously. The limit is calulated based on your validity ration

 

If you reach the limit, you won’t be able to create a new submission until one of your open submissions is processed.

The VSCode remote editor function has really gone to crap recently. Any form of linting is just spinning server CPU at 100% and OOM killing random processes. Going to have to go back to filesystem monitoring and rsync at this rate.

Last BSidesNYC I sat behind a guy doing the CTF with ChatGPT. Ctrl-a paste page source and a screenshot, hit enter, repeat. User totally not reading the output. LLM got the flag (flappybird-style JS challenge) after maybe ten rounds of this. Last message dude sent in the session was "We did it!".

Alex Chapman @ajxchapman.bsky.social · 10/03/2026
Yeah this is 100% what I'm talking about, it _is_ happening, and a whole lot of people are going to be voluntarily less knowledgeable because of it. LLMs are a tool of the future, but we don't need to stop learning because of it.
030
Alex Chapman @ajxchapman.bsky.social · 10/03/2026
I think it's highly likely we'll end up in a split tier future of those that use LLMs without learning, and those that seek to understand what the LLM is doing and learn from it. I believe the latter is the much more desirable camp to be in.

Alex Chapman @ajxchapman.bsky.social · 10/03/2026
This post on LLM use in CTFs sums up my feelings on the subject nicely. vt.social/@lina/116198... When simply directing LLMs for development / security research / CTFs it's quick, often accurate, often useful, but I don't inherently learn anything other than how to direct the LLM.

I wouldn't even attempt to report a bug to a company without at least a VDP / security.txt / security@ these days. The amount of effort for sometimes less than 0 appreciation is just not worth it.

Dad’s books are full of empathy, common sense, and a healthy suspicion of the powerful. But at its heart his work is also about how systems keep people poor while pretending it’s their own fault. So I hope Kemi’s taking notes as well as reading the jokes.
