console.log wrap resolving for your wrapped console logs

I've heard this before:

What I really get frustrated by is that I cannot wrap console.* and preserve line numbers

We enabled this in Chrome DevTools via blackboxing a bit ago.

If you blackbox the script file the contains the console log wrapper, the script location shown in the console will be corrected to the original source file and line number. Click, and the full source is looking longingly into your eyes.

GitHub RCE by Environment variable injection Bug Bounty writeup

Disclaimer: I'll keep this really short but  I hope you'll get the key points.

GitHub blogged a while ago about some internal tool called gerve:
https://github.com/blog/530-how-we-made-github-fast

Upon git+sshing to github.com gerve basically looks up your permission
on the repo you want to interact with. Then it bounces you further in
another forced SSH session to the back end where the repo actually is.
