Suddenly I started receiving a bunch of scam mails (phishing). I suspect some bot or bot-net is involved, because I’ve received maybe a couple hundred e-mails at the time of writing, all from different (likely auto-generated) senders. With anything from 2-10 emails per day.
The scam is essentially just some phishing, all related to the same topic. I’ve mostly been able to mitigate it by filtering out mails containing certain keywords or phrases that show up in the scam mails. However, the mails change relatively often (about once a day) so every now and then something gets through, and I’ll update my filter.
My question is really if there’s any way I can figure out
- Where this is coming from,
- How they got hold of my email
So that I can try to go after the root cause / prevent other scammers from getting hold of it.
Since you chose to point it out: My reason is that I regularly need to be able to log into things on a non-personal machine, sometimes without access to my phone. So no, a password manager for all my accounts is out of the picture. I either write stuff down, remember it, or - sometimes - forget it and need to reset my password.
Not having access to your phone and having to log in on other computers doesn’t rule out using password managers at all. You can use bitwarden’s web vault (or self-host vaultwarden). As long as you can log in to bitwarden web vault, you can access your passwords anytime, anywhere.
