Hot Take:

Looks like the OCC just got schooled in email security 101. Someone needs to tell them that “123456” is not a secure password!

Key Points:

  • OCC identified a major email system breach impacting 103 accounts.
  • Hackers accessed roughly 150,000 emails over several months.
  • Sensitive financial information regarding federally regulated institutions was compromised.
  • Microsoft alerted the OCC to the breach in February 2025.
  • It’s unclear who is behind the attack, though links to previous China-related hacks exist.
