Its “Text” property contains malicious code, which is invisible by default. Inside the VBA project there is a “TextBox” control.

The OLE structure of this sampleįrom the parsing result of the OLE file analysis tool, we can see the VBA code is stored in streams “_VBA_PROJECT_CUR/VBA/ThisWorkbook”, “_VBA_PROJECT_CUR/VBA/Module1”, and “_VBA_PROJECT_CUR/UserForm1/o”. This sample contains modules and controls. Excel Malware Sample 2Īnother Excel malware sample was first collected in our system on Feb 27, 2017. They are used to spread different kinds of malware, including Trojans, Ransomware, Spyware, Bots, etc. In our collection system we gathered lots of Excel samples containing similar VBA code. Finally, the stolen credential data is encrypted and sent to its C&C server.įor more information about Dyzap, you can read the blog from Bahare Sabouri and He Xu.

Second, it generates some strings by concatenating elements of the arrays by their indexes. First, it creates some arrays with short names by calling the Array function. In this sample, the “Shell” function is called at the bottom to execute the malicious command. Based on our analysis of other malicious VBA-based samples, the functions “ShellExecute”, “Shell”, “WScript.Shell”, and “Run” are usually called to execute DOS commands. So I extracted the VBA code from it.Īs you can see from the above VBA code, there is a function named “Auto_Open”, which is called automatically when the file is opened in Excel. The OLE structure of this sampleįrom the parsing result of the OLE file analysis tool, the malicious VBA code exists in the Module1 stream.
