Astra64.sys :inline

Description

ASTRA64.sys is the kernel driver for the ASTRA32 system information tool by Sysinfo Lab (EnTech Taiwan). The driver exposes 31 IOCTLs with zero validation on all parameters including arbitrary physical memory read/write via ZwOpenSection and ZwMapViewOfSection on Device\PhysicalMemory with PAGE_READWRITE, arbitrary port I/O via HalTranslateBusAddress, arbitrary MSR read via rdmsr (enables KASLR bypass via IA32_LSTAR), PCI configuration space read via HalGetBusDataByOffset, and MMIO physical memory mapping via MmMapIoSpace. No authentication gate, no DACL restrictions (plain IoCreateDevice). Loads on any x64 Windows system. EnTech Taiwan also produces TVicPort and softEngine drivers which share similar low-level hardware access patterns. Listed in Eclypsium Screwed-Drivers research.
