According to Kimn Komando’s water cooler:
Mint Mobile data breach: Hackers got away with full names, phone numbers, email addresses, SIM serial numbers and more. I’d be the most worried about the SIMs. SIM-swapping attacks can redirect 2FA texts. Think about all the accounts (like your bank!) that miscreants can get into. Use Mint? I wouldn’t.
If I spot anything else, we’ll let you know. No article is on komando about this one, but that doesn’t mean that someone else doesn’t.
