Just finished reporting a critical vulnerability, but it’s almost midnight and I have school at 7 AM tomorrow. Fingers crossed it gets accepted and isn’t a duplicate 😭

Yay! I just had 7 different reports, which were in the triaged state for almost 2 months, marked as duplicates of a single report. Love bug bounty!

A rating system that hackers can use to provide public feedback about programs.

Performing speculative work for companies that may, or may not, abuse you feels gross.

I recently found a blind FreeMarker SSTI on a bbp. It was not possible to RCE but I found some nice gadgets to enumerate accessible variables, read data blindly or perform some DoS. I documented that here if someone is interested

Thrilled to have my first two bugs accepted! Both are P3s. Still waiting on 14 in triage and 1 in the new state. Feeling more motivated now

Today in my #Hacker #News feed:

Holy crap. Sometimes web research is like magic, all you need is a foot in the door.
Also, how do you screw up authorization so bad?
As a last note, it's unbelievable that EA doesn't have a bug bounty program. Wtf

This is really great research by @ryotak.net -

I appreciated that he covered some of his experiments along the way, and how he landed on a finely tuned way of finding a 12-char hash collision with a command injection payload at the end.

Is it normal for a program to triage bugs in less than an hour sometimes, but then take several weeks to complete validation?

This is so pathetic.

Company with a annual revenue of 25 BILLION USD reduces my bounty by $5 because I didn't supply my IP address.

For a postMessage XSS, so the only thing showing up in their logs would be me opening the homepage...

👋 @bsky.app you are exposing users to potential SSRF attacks in your documentation. Let's fix this.

p.s. you don't have a security contact address in your support website, and no security.txt meta. Let's fix this one too.

Yesterday - found a really nice bug but missing something to achieve greater impact. Decided to sleep on it and figure it out today.

Today - wake up, no electricity 😭 Just hoping no one submits it before me lol

☝️ With Bluesky's increasing popularity, bug-bounty hunters can demonstrate the impact of a subdomain takeover in yet another way: if foo[.]example[.]com is vulnerable, you may be able to claim @foo[.]example[.]com as your handle. Handy for impersonation and phishing. 😈

After more than 6 months of no success in bug bounty I’m finally starting to see results. In the last two week I submitted 12 bugs here are the results:

1 N/A
3 dups
7 in the triaged state !!!
1 in the new state

Let’s hope I finally get some bugs in.
