Use Radare2 and Ruby to develop a malware configuration parser Radare2 (an open-source reverse engineering platform) has received a lot of attention recently. Here I not only want to browse some documents, but also try to use Radare to traverse some code. In 2014, GData released a White Paper on "TooHash action" and introduced a malware called "Cohhoc.

Recently, some customers have requested website logs for analysis. Because the newly installed server has an external system installed, a binary (. IBL) log function. This function is enabled by default in the off-star system. After this function is enabled, all websites on the server write log data to a single log file. The log file extension is. ibl. 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. We recommend that you use the pull parser. 1. Use the pull parser to generate a myitcast. xm
