HTML Smuggling involves leveraging HTML5 and JavaScript to dynamically create a blob (Binary Large Object) containing the malicious payload. This blob is then converted into a downloadable file using HTML5 APIs.
HTML Smuggling is an advanced cyberattack technique where attackers use HTML5 and JavaScript features to create malicious files on the fly within a victim's browser. This method bypasses traditional security measures that scan files at the network perimeter, as the malicious payload is assembled internally within the client's browser, evading detection.
HTML Smuggling involves leveraging HTML5 and JavaScript to dynamically create a blob (Binary Large Object) containing the malicious payload. This blob is then converted into a downloadable file using HTML5 APIs. The attack typically starts with a phishing email or a compromised website, which contains seemingly benign JavaScript code. When a user interacts with this code, it triggers the smuggling process, resulting in the automatic or user-initiated download of the malicious file.
Key features of HTML Smuggling include:
Detecting HTML Smuggling can be challenging, as it uses legitimate web features for malicious purposes. However, certain indicators can help:
To safeguard against HTML Smuggling, organizations and individuals can take several steps:
