According to a recent LinkedIn post from Impart Security, the company is drawing attention to vulnerabilities in how web application firewalls (WAFs) handle payment-card “card cracking” attacks. The post describes how attackers use bots to brute-force CVV values using structurally valid payment requests that appear normal to conventional WAF rules.

The post suggests that meaningful fraud signals emerge only at the application layer, where payment requests can be correlated with processor responses and failure patterns. For investors, this emphasis on application-level detection points to a potential product focus for Impart Security in advanced fraud prevention, which could address a critical need for online merchants and payment processors.
If Impart Security can translate this technical insight into differentiated capabilities, it may strengthen its competitive position in the application security and payments fraud landscape. Growing regulatory pressure and persistent fraud losses in e‑commerce could support demand for solutions that go beyond traditional WAFs, potentially expanding the company’s addressable market and pricing power over time.
