By forcing the flaw, an attacker could attribute malware to a digital signature such as to make its true nature invisible to radar of security software as well as to users' eyes. They would do so the information is at risk saved on devices, from sensitive data to documents, up to credentials for authentication to services and details on payment methods.

The attacker could exploit the vulnerability by using the assignment of a certificate to malicious code, making the file appear as created by a legitimate source. The user would thus have no way of knowing its dangerous nature since the digital signature would appear as attributed to a reliable supplier.
