About SHTM files
A .SHTM file is a web page written in HTML that includes Server-Side Include (SSI) directives. Web servers use these files to dynamically insert content, like headers, footers, or timestamps, into multiple pages before sending them to the user's browser. Historically, software like Microsoft FrontPage utilized this format to manage large websites easily. Today, the .SHTM format is widely abused by threat actors. Attackers use it to bypass email security filters, sending fake login pages as .SHTM attachments spoofing companies like DocuSign or Microsoft. Because these files are less common than standard HTML, they often evade automatic scanning. Opening an unknown .SHTM file in a web browser is highly dangerous because it can execute malicious JavaScript or redirect you to a phishing site. Standard online converters fail to process .SHTM files correctly because they either execute the malicious scripts or fail to parse the server-side directives safely. You need a safe way to extract the text or source code without triggering the payload. Converting a .SHTM file to TXT is the best way to safely read its contents and extract URLs. You can also convert it to PDF to capture the visual layout without allowing active scripts to run. We provide a secure sandbox to inspect the underlying code.
