Closing the path from phishing to fraudulent transfer

An intelligence-led red team proved an external attacker could reach payment-authorization systems, then helped the bank close every step of that path.

The challenge

The bank had passed years of compliance-driven penetration tests but had never measured whether its security operations could detect and stop a determined adversary. Leadership wanted evidence, not assurances, that a phishing email could not become a fraudulent transfer.

Our approach

  • Built an intelligence-led scenario emulating a financially motivated threat group active in the sector
  • Gained initial access through a targeted phishing campaign against a small set of staff
  • Escalated and moved laterally toward payment-authorization systems while tracking detection timing
  • Replayed the full operation with the blue team to tune detections for every technique used

“They showed us exactly how an attacker would move through us, then stayed until our team could see it happening. That changed how we think about detection.”
