Use Radare2 and Ruby to develop a malware configuration parser

In the past, due to the main analysis of the. log file, it was not familiar with binary (. IBL) logs. I checked the relevant information and lear
Sometimes, we need to generate an XML file. There are many ways to generate an XML file. For example, we can use only one stringbuilder to group XML content and then write the content into the file; you can also use the pull parser to generate xml files by using Dom APIs.
