My new site for learning macOS malware reverse engineering:
l0psec.github.io/Malware_RE_…
I got my start in RE by using @patrickwardle's awesome blog. I would download samples and follow along. So I created this to complement that with dives into specific code from recent samples.
.@Volexity has published the third and final installment of its Mind the (Patch) Gap series. Parts 1 and 2 detailed Volexity’s discovery of multiple Chinese threat actors chaining zero-day exploits in Google Chrome and Microsoft Windows to deploy malware. This post takes a closer look at Volexity Volcano, one of the most advanced tools behind those findings.
The blog post also showcases Volcano’s new MCP server for AI-assisted incident response, threat hunting, and digital forensics. Volexity analysts used it to triage a compromised system, automatically annotate related artifacts, create new IOCs for future detection, and schedule targeted collections across endpoints.

So the rust mach-O has obfuscated strings, but not super complicated (yet). BUT this gets pretty long with multiple steps (as with most modern macOS malware) so will try to keep it short. This is the main loader. First we have some anti analysis with ptrace() and sysctlbyname()
Appreciate @jstrosch for the invite on the podcast! macOS malware is at an interesting place. Also, getting to talk about how reverse engineering workflows are changing with AI was fun/therapeutic. I wasn’t crying I promise. 😂
New episode of Behind the Binary is live!
🎙️Joined by @L0Psec to break down macOS security, ClickFix social engineering, InfoStealers (AMOS/MacSync), DPRK developer targeting, and the evolution of obfuscation.
Plus, we talk about how AI is shifting reverse engineering and the inevitable future state...

.@Volexity has discovered in-the-wild exploitation of a #zeroday exploit chain targeting Ivanti Connect Secure VPN appliances (CVE-2026-104935). Beginning October 3, a previously unknown threat actor, UTA0576, chained three vulnerabilities to gain unauthenticated root-level code execution on a fully patched device. Notably, UTA0576 deployed no malware or web shell. Instead, the threat actor re-exploited the device for every command it ran and tampered with logs to cover its tracks, evading Ivanti’s Integrity Checker Tool.
Using its #Volcano memory analysis platform, Volexity analyzed the compromised device’s memory to uncover the full exploit chain and the attacker’s post-exploitation activity, which focused on credential theft, Active Directory reconnaissance, and data exfiltration. Volexity reported these findings to Ivanti through coordinated disclosure.
