Razer Blade Infineon Trusted Platform Module (TPM) Firmware Updater | INTEL-SA-00104

According to Infineon, the TPM is a specialized chip that can securely store critical data such as passwords, certificates, and encryption keys. The update will log events and allow the generation of software-based keys to address the INTEL-SA-00104 vulnerability. This vulnerability weakens key strength which makes it easier for attackers to defeat various cryptographic protection mechanisms via targeted attacks (“CVE-2017-15361 Detail”, 2018).
