RT @BitcoinMagazine: As SIM swapping has become more prevalent, those holding bitcoin on certain platforms are increasingly susceptible to attack.
So how should you protect yourself? https://t.co/ZeVmUe01xk
“Do secure your private keys with hardware devices and multisig. Don't use browser-based wallets as they have huge attack surfaces. Do use hardware-based 2FA for any web app that supports it. Don't use SMS 2FA or enable online accounts to be reset/recovered via a phone number.”
— Jameson Lopp
That's it, you shouldn't set up Coinbase to send you codes over SMS, use Google Authenticator instead which is tied to the device itself, not the phone number.
Or better yet, as everyone keeps saying over and over again: get yourself a hardware wallet from Ledger or Trezor and get your coins off the exchanges.
i've always said this is how you get added to telemarketer lists... if you answer it at all you get a little checkmark next to your number that you answer it, and then your number gets sold more and used more. not answering any number you don't know for like 5 years will get your number to drop off these lists.
For several years I got maybe two or three spam calls a year because I never answered it. Recently made some big purchases and I feel the lenders or dealership sold my number and they started back up but are tapering off after a couple years. It does help to just not answer and have the default voicemail
I used to think it was coincidence, and I haven't used ebay in a while, but when I did, without fail I'd get multiple calls (never pick up of course).
Oh, and quicken loans STILL calls me from several different numbers for the past year. I blocked a few but they still call from new ones. Best part is, all I did was put in my name and number and clicked "next", never even signed up for anything. The second I clicked next, my phone rang. And the voicemails they'd leave are fabricated stories about how we spoke the other day and turns out they can give me a better deal than what was discussed. /rant
