HtmlSmuggling

HTML smuggling is a malicious technique used by hackers to hide malware payloads in an encoded script in a specially crafted HTML attachment or web page.
The malicious script decodes and deploys the payload on the targeted device when the victim opens/clicks the HTML attachment/link.
The HTML smuggling technique leverages legitimate HTML5 and JavaScript features to hide malicious payloads and evade security detections.
The HTML smuggling method is highly evasive. It could bypass standard perimeter security controls like web proxies and email gateways, which only check for suspicious attachments like EXE, DLL, ZIP, RAR, DOCX or PDF
Embeds the selected binary file (exe, dll, docx, pdf, etc) into the Javascript file. Obfuscates Javascript functions. This makes it difficult to decode javascript functions.
Once a victim receives the email and opens the attachment, their browser decodes and runs the script, which then assembles a malicious payload directly on the victim’s device.
