ModerateAffected 2 Oct 2026 – 8 Oct 2026 · contained 9 Oct 2026SBI SECURITIES warning: passkeys used through hijacked Google and Apple accounts (October 2026)

SBI SECURITIES warned that criminals are phishing Google and Apple account logins, then using the passkeys and password notes synced to those accounts to sign in to brokerage accounts and trade. The cases were reported at other securities firms; SBI SECURITIES says none of its own accounts have been hit. If your passkeys live in a Google or Apple account, protect that account as carefully as the brokerage login itself.

What to do (5 steps)
  1. On the Google or Apple account that stores your passkeys, check two-step verification and the recovery email and phone, and remove devices you don't recognise. ↗
  2. Sign in to SBI SECURITIES with a passkey and turn off the login password.
  3. Don't keep brokerage passwords in cloud notes or anywhere else a phished account would reveal.
  4. Don't sign in through links in emails or texts; open the site or app directly.
  5. Check trading history and the contact details on the account for changes you didn't make.
