An SVG attachment refers to a file in the Scalable Vector Graphics (SVG) format that is sent as an email attachment. While SVG files are typically used for displaying vector images, they can also contain embedded scripts or malicious code. Cybercriminals exploit this capability to bypass traditional email security filters, as SVG files may not be as rigorously scanned as other file types. Once opened, a malicious SVG attachment can execute harmful code, redirect users to phishing sites, or download malware onto the victim's device. It is important to treat unexpected SVG attachments with caution and ensure robust email filtering is in place.
