How To Hunt For UEFI Malware Using Velociraptor
UEFI threats have historically been limited in number and mostly implemented by
nation state actors as stealthy persistence. However, the recent proliferation
of Black Lotus on the dark web, Trickbot enumeration module (late 2022), and
Glupteba (November 2023) indicates that this historical trend may be changing.

Introspective Intelligence: Understanding Detection Techniques
To provide insight into the methods devised by Rapid7, we'll need to revisit the
detection methods implemented across InfoSec products and services and how we
apply data differently. Rapid7 gathers volumes of threat intelligence on a daily
basis - from new penetration testing tools, tactics, and procedures in
Metasploit, vulnerability detections in Nexpose, and user behavior anomalies in
InsightIDR. By continuously generating, refining and applying threat
intelligence, we enable more robust dete

Malware and Advanced Threat Protection: A User-Host-Process Model
In today's big data and data science age, you need to think outside the box when
it comes to malware and advanced threat protection. For the Analytic Response
team at our 24/7 SOC in Alexandria, VA, we use three levels of user behavior
analytics to identify and respond to threats. The model is defined as
User-Host-Process, or UHP. Using this model and its supporting datasets allows
our team to quickly neutralize and protect against advanced threats with a high
confidence rate.

ByeBye Shell and the targeting of Pakistan
Asia and South Asia are a theater for daily attacks and numerous ongoing
espionage campaigns between neighboring countries, so many campaigns that it's
hard to keep count. Recently I stumbled on yet another one, which appears to
have been active since at least the beginning of the year, and seems mostly
directed at Pakistani targets.
In this article we're going to analyze the nature of the attacks, the
functionality of the backdoor - here labelled as ByeBye Shell - and the quick
