Proven Results

Critical Vulnerabilities We've Eliminated

When critical vulnerabilities exist, we find them. The following anonymised case studies showcase some of the most significant security issues we have uncovered and helped our clients resolve before they could be exploited.

Australian Education Platform

During a security assessment of a large Australian education platform, we discovered a hidden weakness that allowed our testers to read private files stored directly on the organisation's server — including sensitive configuration data that should never be exposed.

  • Vulnerability: Unauthorised server file access via XML injection
  • Risk: Sensitive internal files readable by any outside attacker
  • Outcome: Vulnerability identified, reported, and fully remediated

Australian Travel Company

While testing a travel booking platform, we found a flaw that allowed a user to secretly alter the price of flights and accommodation at checkout. Left undetected, this could have been exploited to make bookings at a fraction of the real cost — causing direct financial loss to the business.

  • Vulnerability: Booking price manipulation during checkout
  • Risk: Financial loss through fraudulent low-price transactions
  • Outcome: Flaw uncovered before any financial damage occurred

Australian SaaS Company

On a cloud-based software platform, we uncovered a critical weakness that would have allowed an attacker to log in as any user on the system — including administrators — without needing to know their password. This type of vulnerability puts every user's account and data at immediate risk.

  • Vulnerability: Full account takeover without user credentials
  • Risk: Any user account — including admin — could be compromised
  • Outcome: Issue resolved before any accounts were affected
