Cuckoo Sandbox – Automated Malware Analysis System


Cuckoo Sandbox is a malware analysis system. It simply means that you can throw any suspicious file at it and in a matter of seconds Cuckoo will provide you back some detailed results outlining what such file did when executed inside an isolated environment.
Cuckoo generates a handful of different raw data which include:
  • Native functions and Windows API calls traces
  • Copies of files created and deleted from the filesystem
  • Dump of the memory of the selected process
  • Full memory dump of the analysis machine
  • Screenshots of the desktop during the execution of the malware analysis
  • Network dump generated by the machine used for the analysis
In order to make such results more consumable to the end users, Cuckoo is able to process them and generate different type of reports, which could include:
  • JSON report
  • HTML report
  • MAEC report
  • MongoDB interface
  • HPFeeds interface
Even more interestingly, thanks to Cuckoo’s extensive modular design, you are able to customize both the processing and the reporting stages. Cuckoo provides you all the requirements to easily integrate the sandbox into your existing frameworks and storages with the data you want, in the way you want, with the format you want.
