I received 30+ emails in all languages (often eastern European) that always say the same thing :
"hello
We received a request to access project-0000000000 with this email address. If you want to sign in with your (your email) account, click this link:
Access to project-0000000000
If you didn't request this connection, ignore the email.
With respect,
project-0000000000 team"
I have received 30+ of these, without any prior action on my side. They generally have an URL "leading to the project". The URL seems based on firebase as well (xxxxxxx.page.link/?link=https://0000000000.firebase.com/...), but I wonder if it could be malicious, depending on what comes at the end of the URL, I guess.
If it's an attack, I guess the vector attack is the URL, because I cannot see any other option.
If it's not an attack, I wonder why on earth I receive all the emails, and what I can do about it.
The strangest thing, for me, is that I once received an email in Turkish thanking me for my contribution to one project. This email had no URL, so no obvious attack vector. I don't know if it was a case of social engineering, or if someone is impersonating my email address to use firebase.
Do someone know what could be going on ?
