What Happened

In May 2026, the telecommunications company Charter Communications (the parent company behind the consumer broadband and cable brand Spectrum) was named by the ShinyHunters group in a "pay or leak" extortion campaign. The group later published the data, which exposed 4.9M unique email addresses along with names, phone numbers and physical addresses. A subset of approximately 85k records originating from an internal employee directory also included job titles. Charter confirmed the incident, but stated that no sensitive personal information or customer proprietary network information (CPNI) was exfiltrated.

Impact

  • Affected accounts: 4.9M
  • Data exposed: Email addresses, Job titles, Names, Phone numbers, Physical addresses

    • What You Should Do

    If you have an account with Charter, take these steps immediately:

  • **Change your password** — Use a unique, strong password (16+ chars with mixed case, numbers, symbols)
  • **Enable 2FA** — Turn on two-factor authentication if available
  • **Check your email** — Search for breach notifications from Charter
  • **Monitor your accounts** — Watch for unauthorized access on any service where you reused the same password
  • **Scan your site** — If you run a website, [run a free ScanMyVibe scan](https://scanmyvibe.co/scan) to check if your own security headers and configurations protect against common attack vectors

    • Is Your Website Secure?
