How to effectively target Bootkit Trojans

How to effectively target Bootkit Trojans

Bootkit is usually infected with MBR or VBR. It copies the code to the memory and then executes malicious code. Sometimes, they hook the INT 13/15 interrupt handler to filter out memory and disk access and protect the infected MBR/VBR and kernel driver.

Install anti-virus software

The BMW virus consists of three parts: BIOS, MBR, and Windows. Generally, security software with active defense can defend against mbr bootkit by intercepting write operations on the MBR region at the RING3 application layer and blocking malicious driver loading. When security software protection is enabled, the user will not be infected with mbr bootkit, such as BMW and ghost shadows.

Intercept beforehand

To deal with Bootkit, we should not simply focus on the behavior after the Bootkit is executed, but should comprehensively check the process from the source to the result in a global view, that is to say, to improve the comprehensive monitoring capability of the security software, and intercept the line of the original virus body installed with Bootkit, which is more effective than after-event detection and removal.
