    If I know your phone number, I can kill on your phone - and there's nothing you can do to stop me - not even 2FA. Worse, won't confirm that they'll fix it. This vulnerability is live right now. ICYMI .

    My flaw story now updated. It seems has known about this vulnerability since at least Dec 2020. They won’t acknowledge it is an issue or confirm it will be fixed. Maybe all the negative media this week will change their minds.

    If we don’t separate real hacks from sensationalised data scrapes, then we detract from the real issues and the real culprits. Public data on social media sites is public data on social media sites.

    This isn't a hack, and it's inevitable someone would do this. Someone scraped data of 1.3 million Clubhouse users - names, social media profile names, and other dets. Clubhouse says it's all "public profile information from our app, which anyone can access via the app or our API”

    “Imagine if your government could see every transaction you made... or your boss could see every text message or photo you sent... That’s the greatest risk of all... Surrendering your privacy." Incredibly, this ironic warning comes from a exec.
