Why does the DeepCDR engine delete the content of the HTML file?

When scanning HTML files, the Deep CDR engine reconstructs the content to remove potentially malicious or hidden elements that could pose a security risk. One common reason for content being removed is the presence of specific CSS attributes or styles used to hide information from the visible page is the font-size:0px.

As seen from the image all the content in the <div> got removed.

Since Deep CDR recognizes these CSS attributes as methods used to conceal content, the information inside <div> elements that use specifically (font-size:0px) is removed during the sanitization process.

For a current workaround, we will need to disable the “Process Zero Font Text” to make sure that the Deep CDR does not recognize those elements as zero font text.
