Hive0051’s large scale malicious operations enabled by synchronized multi-channel DNS fluxing

12 min read - For the last year and a half, IBM X-Force has actively monitored the evolution of Hive0051’s malware capabilities. This Russian threat actor has accelerated its development efforts to support expanding operations since the onset of the Ukraine conflict. Recent analysis identified three key changes to capabilities: an improved multi-channel approach to DNS fluxing, obfuscated multi-stage scripts, and the use of fileless PowerShell variants of the Gamma malware. As of October 2023, IBM X-Force has also observed a significant increase in…

Reflective call stack detections and evasions

6 min read - In a blog published this March, we explored reflective loading through the lens of an offensive security tool developer, highlighting detection and evasion opportunities along the way. This time we are diving into call stack detections and evasions, and how BokuLoader reflectively loads call stack spoofing capabilities into beacon. We created this blog and public release of BokuLoader during Dylan’s summer 2023 internship with IBM X-Force Red. While researching call stack spoofing for our in-house C2, this was one of…

SIEM and SOAR in 2023: Key trends and new changes

4 min read - Security information and event management (SIEM) systems remain a key component of security operations centers (SOCs). Security orchestration, automation, and response (SOAR) frameworks, meanwhile, have emerged to fill the gap in these capabilities left by many SIEM systems. But as many companies have begun reaching the limits of SIEM and SOAR systems over the last few years, they have started turning to other solutions such as extended detection and response (XDR). But does this shift spell the end of SIEM…

Threat hunting 101: How to outthink attackers
