Summary

Dana Behling, researcher from Carbon Black, sharing their work on "Hunting Vulnerable Kernel Drivers." The Carbon Black Threat Analysis Unit (TAU) discovered 34 unique vulnerable drivers, six of which allow kernel memory access, accepting firmware access. TAU reported the issues to the vendors whose drivers had valid signatures at the time of discovery, but only two vendors fixed the vulnerabilities. TAU is calling for more comprehensive approaches in the future than the current banned-list method used by Microsoft. The research states "By exploiting the vulnerable drivers, an attacker without the system privilege may erase/alter firmware, and/or elevate privileges."
