Project successful. Found my first bug using an LLM!
My project this week includes Langchain project to analyze javascript files.

I've actually had some pretty good results so far. Having an LLM make decisions in a program's execution is really interesting and useful (when it works).

Though, I have no idea how anyone uses this in production.

It's a shame there are no maintained Langchain implementations for Go. Had to switch to Node because of the limitations with the current, unmaintained Go library.

Slow bug bounty year for myself. 2024 stats...

5 lows
4 mediums
9 highs
3 criticals

While my number of submissions was very low, my average bounty was around $11,200, allowing me to only submit a couple bugs a month without feeling too bad.

What are US based bug bounty hunters doing full time nowadays? Full time bug bounty? Security engineering? Research?

I want a way to change code execution flow of javascript within the browser. I'd love to be able to do this through an extension, but there seem to be too many limitations (i.e. no ability to monitor / modify conditional statements at runtime).

I'd like to avoid a simple match replace. Any ideas?

Starting to think of bug severity in terms of "how might this affect shareholder price". At the end of the day, that's all that the companies who determine your bounty amount care about. Your data is already public from other breaches, but those breaches may not be associated to that company (yet).
