Looks like the phishing attempts impersonating the IACR board are back. Be safe. @IACR_News @TheAlliBishop @michelabdalla
Several people contacted me today because they received a phishing email pretending to come from me and asking them if they could spare me a few minutes to help the IACR board. Please ignore that email. It's a scam!

"Oh?" - me noticing a post about NIST PQC and Kyber on the HackerNews front page; "Oh no" - after reading the domain name; [Facepalm] - after taking a peek at the comment section.

Non qu'on ait jamais eu d'illusion à ce sujet, mais il faut arrêter de donner des responsabilités à des startupeurs, vraiment.
La France doit être souveraine sur les nouvelles technologies basées sur la blockchain, comme les NFT. Car en soutenant l’innovation, nous créerons de l’emploi.

I didn't have high expectations but I'm still disappointed. Does anyone know real people remaining at @X that could address this straightforward case of impersonation?
Indeed, I'm blocked so it wasn't showing up in search results! Reported; let's hope @X acts swiftly...

That's concerning. Can't find the account right now so I assume it's been closed down, but if anyone received a message like that, don't hesitate to report it. As a reminder, the only blockchain I endorse is: store.newae.com/blockchain/
Hey @mtibouchi, you have a fake crypto scam account with an 0 instead of the o in your login... (Or you decided to speak to me in English about crypto trades...)

Dear chairs of crypto/security conferences: don't do this. Terrible idea.
Received from AsiaCCS'23 co-chairs: "we strongly discourage publishing submissions on Arxiv, Crypto Eprint, and similar releases."
