Out of idle daydreaming (because I had bought a ticket), I started wondering what I would do right after discovering I won (and yes, I've seen that Reddit post with all the financial, legal advice). I don't mean who I would give money to, or what to do with the $. No, I'm talking about technology-wise, would I (in the interest of protecting my newfound $): -- Before claiming prize, immediately disconnect/uncouple all financial apps and services from my publicly discoverable phone number (to prevent financial hijacking of accounts) -- Disconnect my phone number from my iCloud / iMessage and link instead with my private email address (to isolate randos contacting me by phone number) -- Take the approach to get 3-4 clean iPhones, Phone #1) for iMessaging / Whatsapping with friends, family who have my email, Phone #2) a new phone number for only answering telephone calls from same, Phone #3) for all financial matters/apps, and phone is used only for that Phone #4) my old phone number in case I still need to receive something, but which will get flooded with spam. -- Remove any public videos of myself, or even wipe my voicemail recording, so that my voice is not known to anyone and could be used maliciously? -- Would I swear off any further commenting (or even delete my accounts) on Reddit, HN, other sites for fear that it could link back to me and open me to some hacking vulnerability? The phone strategy above is with the notion that someone sends you a poisoned text message and it scrapes/hijacks your financial accounts, etc. All of this of course focused on the likelihood that once your name becomes public, hundreds of malicious actors will be trying to find some way into your accounts. Or is it that when you reach this tier of having money, your banking is just not done the same way any more? And then all the usual of moving to a temporary private / unknown address, talking to lawyers/finance, going on vacation for a year, etc.
