danaConfig
DanaConfig is a static configuration extractor implemented in Golang for the main component of DanaBot (targeting Microsoft Windows). By default the script will print the extracted information to stdout. It is also capable of dumping the malware configuration to disk as a JSON file with the -j flag.
Usage
go run danaConfig.go [-j] path/to/danabot_main.dll
Screenshots
The script itself, running in verbose mode and with JSON output enabled:

Sources/Credits
