GuLoader malware can be downloaded or created in various ways, but the most common one includes the use of a document attachment with a macro that will execute a malicious payload or an exploit like CVE-2017-11882. GuLoader is unique in that it is written in Visual Basic 6 and contains a Shellcode payload wrapped inside.
Yet, like many of today’s malware strains, GuLoader also uses a variety of self-defense mechanisms to evade detection and defense.
