Malware monitor - leveraging PyREBox for malware analysis

Summary: Cisco Talos released a set of PyREBox scripts called Malware monitor that automate code coverage analysis, API tracing, memory monitoring, and process memory dumping for malware analysis. The scripts, announced at the Hack in the Box CommSec track in Amsterdam, generate binary traces and text logs that can be imported into IDA to colorize executed code blocks and inspect API calls and parameters.

Bottom line: The tooling targets the deployment phase where malware injects payloads into system processes, creates processes, or drops files to disk - the window where an analyst has to decide when to dump memory before the sample is fully unpacked.
