This. I help-desked through college, worked as a SDE for 11 years & just randomly was on call when AMZN was 1st hit w an XSS attack 25 years ago & we had to reverse engineer on the fly what was happening & how to protect against it. Webappsec wasn't even a field for another 10ish years after that.
I was in IT (it's been almost 20 years) doing QA/support shenanigans before this field was a known money-maker.
Now that it is, everyone wants a quick way in.
This comic about covers it while still managing to leave out DFIR.
Anyone who sells you on "quick & easy" is slinging snake oil.

According to LinkedIn I've been working in/on Open Source for 11 years. I suspect that's on the low side, between ZAP and OWASP, but whatever.

what's security like in these? i haven't been doing it for a minute but back when i was in webappsec angular was hot shit (or at least most the secure devs i knew seemed to think so)

#WednesdayWin I had a PR merged this morning which means none of ZAP's core scan rules (active and passive) no longer use CWE-200 which is not supposed to be mapped 🥳🎉

not really, like i said elsewhere i'm a generalist

webappsec for a couple years, pro-services for an appliance vendor that required very broad knowledge for a while, last job was first security hire/director of security for a start-up, mostly prep a soc 2 audit that was extremely in distress lol

oh FUCK no but when i get home i bet i know a few people (local citysec meetup in sf used to be lousy with cryptographers)

that's way beyond me, hard crypto shit

i started out doing webappsec and pivoted into management after experiencing very bad management

i'm a generalist, that's specialist

I'd seen this before, where an LLM retrospectively hides a response; it kind of feels like an "attack", but is it better classed as a "design flaw"?

I'm not sure that this seen in WebAppSec ( it's been a while ) where the data is retrospectively acted on - rather than hidden from the start?
These aren’t new LLM attacks. They are UI and architecture bugs that we’ve known since the very beginning of WebAppSec. If you send data to a user’s browser, they can capture and view it. 🤷‍♂️ www.knostic.ai/blog/introdu...
