The smartpss.exe file contained metadata describing itself as MSHTA.exe from Microsoft, a legitimate operating system component, but the MD5 hash was unknown. Disassembly analysis of the program showed it was a small application that loaded the IE COM object and launched the function RunHTMLApplication() against the command line argument provided. This functionality matched the behavior of the legitimate MSHTA.exe despite the hash discrepancy. Further analysis showed that the malware was based on a 2018 version of the binary (original hash: 5ced5d5b469724d9992f5e8117ecefb5) with only six bytes of data appended, as shown in Figure 4.
