Memhunter Automated Hunting Of Memory Resident Malware

### Automated Detection of In-Memory Resident Threats At 00:00, security researcher Carlos Garay introduces Memhunter, an open-source endpoint detection tool designed to identify and remediate fileless, memory-resident malware, at the Blue Team Village. Garay discusses the rise of memory-only attacks in modern adversary campaigns.

### The Mechanics of Fileless Malware Execution At 08:33, Garay reviews how fileless malware evades disk-based endpoint protection. Adversaries leverage malicious macros, living-off-the-land binaries (LOLBins), and Win32 memory APIs (such as `VirtualAllocEx` and `WriteProcessMemory`) to inject shellcode directly into trusted Windows processes.

### Endpoint Scanning Heuristics and Memory Inspection At 16:43, the presentation explores Memhunter's scanning architecture. The tool analyzes running processes to detect unbacked executable pages, abnormal thread start addresses, and modified export tables, generating structured alerts without imposing heavy system overhead.

### Live Process Freezing and Forensic Analysis At 25:13, Garay demonstrates Memhunter's active intervention capabilities. Upon detecting suspicious memory activity, the utility temporarily suspends the offending process threads, freezing malicious execution in place while performing deeper heuristic analysis.

### Detecting Process Hollowing and RWX Memory Pages Concluding between 33:38 and 40:00, the speaker details techniques for identifying process hollowing and anomalous Read-Write-Execute (RWX) memory allocations. He outlines how blue teams can integrate Memhunter telemetry into SIEM pipelines to automate memory threat hunting across enterprise fleets.
