TrickBot’s new module aims to infect your UEFI firmware

The developers of TrickBot have created a new module that probes for UEFI vulnerabilities, demonstrating the actor’s effort to take attacks at a level that would give them ultimate control over infected machines.

With access to UEFI firmware, a threat actor would establish on the compromised machine persistence that resists operating system reinstalls or replacing of storage drives.

Malicious code planted in the firmware (bootkits) is invisible to security solutions operating on top of the operating system because it loads before everything else, in the initial stage of a computer’s booting sequence.
