Attackers can conceal suspicious data inside files that appear to be ordinary images, including appended content, unusual metadata, embedded scripts, malformed structures, and concealed instructions. PixScanner examines every uploaded image checking whether its contents match the expected image format and identifying anomalies that may indicate manipulation or hidden payloads. Suspicious uploads can then be safely handheld before they become accessible through your website or create unnecessary security exposure.
Confirms each upload's MIME type, extension, and file signature are consistent with a supported image format.
Parses image structures to identify malformed headers, invalid segments, unexpected chunks, and anomalies requiring administrative review.
Examines image metadata for unusual fields, oversized entries, embedded content, or patterns inconsistent with normal media files.
Detects unexpected data placed after an image's valid ending marker, which may indicate concealed or manipulated content.
Looks for scripts, executable markers, suspicious strings, and non-image content embedded within supported image file structures.
Allows suspicious uploads to be blocked, quarantined, logged, or flagged for review according to configured security policies.
