Run a fleet-wide scan for the SHA-256 hashes identified in Section 2.
Execution of the primary binary within a controlled sandbox environment showed:
The malware modifies the Windows Registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Run to ensure execution on boot.
This report details the investigation into the compressed archive Denim_Reflux_Roving_Dove.7z . Initial triage suggests the archive contains artifacts related to a [state-sponsored/ad-hoc] campaign targeting [Industry/Sector]. Preliminary analysis identifies the presence of [malicious binaries/encrypted databases/exfiltrated logs], suggesting a focus on long-term persistence and data collection. 2. File Information Denim_Reflux_Roving_Dove.7z Format: 7-Zip Compressed Archive (LZMA2) MD5: [Insert Hash] SHA-256: [Insert Hash]
Upon extraction, the archive revealed the following directory structure:
/logs/ : Automated exfiltration logs detailing system reconnaissance. 4. Technical Analysis 4.1 Behavioral Analysis
The "Roving Dove" module checks for the presence of debuggers (e.g., OllyDbg, x64dbg) and terminates if detected. 4.2 Code Capabilities
/config/ : Encrypted configuration files containing C2 (Command & Control) infrastructure details.
