A machine‑learning method to explore the UEFI landscape
Building on their earlier work on UEFI threats, ESET experts describe how they trained a machine-learning model to recognize a handful of unwanted UEFI components within a flood of millions of harmless samples. Besides showing strong capabilities in identifying suspicious UEFI executables, this system offers real-time monitoring of the UEFI landscape and was found to

LOJAX: First UEFI rootkit found in the wild, courtesy of the Sednit group
ESET researchers have discovered the first in-the-wild UEFI rootkit. Dubbed LoJax, the research team has shown that the Sednit operators used different components of the LoJax malware to target a few government organizations in the Balkans as well as in Central and Eastern Europe. The Sednit group is a resourceful APT group targeting people and

Fighting persistent malware with a UEFI scanner, or ‘What’s it all about UEFI?”
The biggest news in malware so far this year has been WannaCryptor a.k.a. WannaCry, and one reason that particular ransomware spread so fast was because it used a “top secret” exploit developed by the NSA, an agency known to have dabbled in UEFI compromise.
UEFI malware: How to exploit a false sense of security
When thinking about security we generally take risk into account. It is well known that risk is a composition of likelihood and potential impact.
