9/24/2023 0 Comments Microsoft update trend micro![]() ![]() Trend Micro could have just left the Windows 10 check, why would you even bother creating an explicit check for Driver Verifier?” I don’t understand why Trend Micro would go out of their way to cheat in these tests. Instead of complying with this requirement designed to secure Windows users, Trend Micro decided to ignore their user’s security and designed their driver to cheat any testing or debugging environment which would catch such violations. “On Windows 10, Driver Verifier enforces that drivers do not allocate executable memory. “Passing Driver Verifier has been a long-time requirement of obtaining WHQL certification,” Demirkapi said in his research. When the test isn’t running, however, it requests memory from the executable non-paged pool. When tmcomm runs on a machine with the test in play, it demands memory from the no-execute non-paged pool, as expected. This is non-executable for the CPU, meaning if hackers manage to hide malicious code in the memory, by exploiting a security lapse in the code, for instance, then it’s extremely difficult to run.ĭriver Verifier tests for whether drivers use non-executable memory in this way. To pass the test, any software must use memory from the operating system's no-execute non-paged pool, as a precaution. Therefore, the driver at the heart of Rootkit Buster can "cheat" these hardware examinations and gain WHQL certification. The software performs checks for Driver Verifier, and can thus adapt to behave differently on systems running the examination. In passing the test, a driver is digitally verified and can even be potentially distributed through Windows Update. Participants in the MAPP program gain access to this threat intelligence before the public releases so their customers can be protected when the patches are live.WHQL, of which Driver Verifier is a key component, is a procedure for certifying that hardware for peripherals and other components is compatible and works as expected with Windows operating systems. This analysis is provided to Independent Software Vendors (ISVs) and AV Providers to help scan and detect these potential vulnerabilities, to help prevent them from occurring in the wild. Because our collaboration, we felt confident in allowing Trend Micro to perform vulnerability research and analysis on Adobe proof of concept files (POCs). ZDI researchers are responsible for submitting several innovative defense-in-depth solutions that helped reduce the attack surface within Adobe products.
