anti-AI scraping is often anti-privacy in practice, as any effective implementation requires invasive browser inspection to detect scrapers.

The web is for bots now. Humans are the minority and will get pushed out, or leave in the face of various pending identity verification schemes to get past the bot filters.

The idea wasn't really named/documented until ~1997 (I think), but the seed of it was in Tim's original WWW proposal from 1989.

Re:A complete bypass of eMudhra’s 1FA OTP login system by gruez on Thursday October 22, 2026 @04:08PM (#50200299)
Only if they're lazy and went with the "download key and certificate (and we'll generate the keys for you)" option. Otherwise at least how it's supposed to work is that you give a CA a certificate signing request (CSR) containing your public key, they sign it and hand back your certificate. The certificate itself doesn't contain anything sensitive, because it's the same thing that your server presents to clients. But people are lazy and might not know how to generate a csr locally, hence the aforementioned option. And of course if they're too lazy to generate a csr locally, they're probably also too lazy to keep backups, so you can be sure that eMudhra keeps a copy in case they deleted it from their downloads folder.

I noticed that as well. Figured it was a concurrency issue, and they have a follow-up message that you can see if you click on the OP of the Mastodon thread that confirmed my guess: https://mastodon.catgirl.cloud/@49016/117476097901925573

>(yes the code is off by a few. its bc the poc is shit and to speed it up it uses 8 connections at the same time. it just stops the counter once it has a hit so its off by ~4 lmfao. you could easily fix this but cba today)

Yes, it’s a complete auth bypass. All you need is the email address of a user and they’ll likely sign CSRs for any domains under that account.

It’s the end for them, I imagine.

If anyone knows another way to access the content, I'd be interested. No contact details are offered and visiting mastodon.catgirl.cloud resets my connection.

Re:A complete bypass of eMudhra’s 1FA OTP login system by ignatella on Thursday October 22, 2026 @05:15PM (#50201159)
I understand it in the following way:

They put the public key into js and encrypt the body of the request. This is common practice to protect users' important data from being accessed by a proxy (in this case, Cloudflare) and is ok.

But the real bug is that they don't rate-limit, invalidate, or protect the endpoint related to OTP checks, so it can be brute-forced, as the search space is limited.

Please express this succinctly when talkers like me "get going" – I appreciate that not everybody wants these brief connections (you won't hurt my feelings with a simple "hey I'm not really much for talking").

If you prefer wordless silence, pulling out a phone (or book/magazine) works well when talkers "don't take the hint;" or face away (for particularly invasive conversation starters).

My hope is that small talk leads to shared connections, perhaps even (a brief intertwining of) humanity.

If anyone can guess or brute force the factor, it's approaching 0FA.

It's like fractals, not all dimensions are integers. If your one factor is extremely weak, then it's really only 0.x of a factor.
