193,000 Customers Affected in Pizza Hut Australia Breach


Pizza Hut Data Breach

Pizza Hut Australia has publicly disclosed a cybersecurity incident affecting approximately 193,000 customers. The compromised data ranges from personal details to encrypted credit card numbers.

How Did the Attackers Get In?

While the exact method used by the attackers to breach Pizza Hut’s systems hasn’t been disclosed, there are common attack vectors that often come into play in similar cases:

  • Zero Day Attacks: Exploiting unknown software vulnerabilities before they can be patched.
  • Credential Theft: Unauthorised access using stolen login credentials.
  • Business Email Compromise: Manipulating internal communication to gain access or information.

For more information on how to protect yourself against these types of attacks, see our guides on Zero Day Attacks, Credential Theft, and Business Email Compromise.

What Was Compromised in the Breach?

The following types of data were compromised in the Pizza Hut Australia hack, according to the email sent to affected customers:

  • Customer names
  • Delivery addresses and special instructions
  • Email addresses
  • Contact numbers

For registered users:

  • Masked credit card details (unusable for fraudulent purchases)
  • One-way encrypted passwords (can’t be directly used for access; requires significant effort to decrypt)

Maintaining Operations After the Breach

Pizza Hut Australia managed to keep its business running even after the breach. Several cybersecurity best practices likely played a role in this resilience:

  • Incident Response: Pizza Hut likely had a plan in place for handling security incidents, minimising damage and restoring normal operations quickly.
  • Managed Security Services: Expert teams were likely engaged to monitor and manage the breach, a practice commonly used to maintain business continuity.
  • Ongoing Audits: Consistent security checks can identify vulnerabilities early on, providing the chance to fix them before they are exploited.
