7 Vulns in 7 Days: Breaking Bloatware Faster Than Vendors Can Ship

Julian Horoszkiewicz

Demonstrates rapid vulnerability discovery methodologies that uncovered seven zero-day local privilege escalation flaws in pre-installed OEM bloatware.

Summary

The Attack Surface of Pre-Installed OEM Software

Consumer and enterprise laptops ship with pre-installed OEM support tools and diagnostic utilities. These privileged background services frequently introduce critical vulnerabilities.

Rapid Vulnerability Discovery Methodology

Julian Horoszkiewicz outlines a fast-paced auditing approach that uncovered seven separate local privilege escalation vulnerabilities in OEM software suites within a single week.

Exploiting Insecure IPC, Named Pipes, and Services

Common flaw patterns include unauthenticated named pipe commands, DLL hijacking in SYSTEM services, and flawed registry permissions that allow low-privilege users to execute code as NT AUTHORITY\SYSTEM.

Remediation and OEM Supply Chain Hygiene

Eliminating bloatware risks requires hardware vendors to minimize pre-installed software, enforce strict service access control lists, and undergo rigorous third-party security audits prior to device imaging.
