Threat actors utilize HTML Smuggling techniques in recent campaigns to deliver Qakbot XWorm Cobalt Strike and IcedID.
Initially a spear-phishing email is sent to the target with an HTML attachment once opened the HTML file may directly drop an archive file containing a malicious LNK file to the victim machine or present a file impersonating well know vendors such as Adobe Google or Dropbox.
The victim is then coerced into executing the archive or saving and executing a malicious file in the form of an .ISO .IMG or VHD image file.
In either scenario the file contains an LNK file that executes commands to load a decoy file and uses the native binary rundll32 to load the malware payload.
