MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1600.001 Reduce Key Space Defense Impairment
Adversaries may reduce the level of effort required to decrypt data transmitted over the network by reducing the cipher strength of encrypted communications.
Why these techniques?

Public-facing web application vulnerability in payment handler with insufficiently random values enables exploitation for initial access (T1190) and facilitates weakening encryption via reduced key space (T1600.001), as explicitly mapped in VulDB advisory.
