Context
Octowave Loader is a malware loader used to run other families of malware. This is often made up of an MSI or Inno Setup installer for a legitimate piece of software that has been trojanised to include a number of malicious DLLs which inevitably load and run malicious code often stored within a WAV file that is also delivered to an endpoint. In the wild this has been seen delivered through fake software installers and ClickFix / Fake Captcha campaigns. Families of malware deployed often include information stealers, NetSupport RAT, and potentially bots like Danabot.
