T1566.002 Spearphishing Attachment
The PDF document contains an embedded JavaScript stream and uses an ASCII85Decode filter, both common techniques for obfuscating malicious content. The ML classifier flagged this PDF as malicious with a high probability. The document is structured as an image-only lure, typical of phishing attempts, and contains a clickable external URI pointing to 'https://mardurasp.com/se/?fjLkWcdWofJCWzViUmCZnIBpsVLlGWmnNcUTKkGlDhFBcvCHzFeQglEvkfQLJQPyJrIHXtmLqWRwr'. This suggests the document's primary purpose is to redirect the user to a malicious website for further exploitation.

Heuristics 5
-
Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LUREPDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 276 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
-
Embedded JS stream low PDF_JSPDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
-
ASCII85Decode filter (with exploit indicators) low PDF_FILTER_85ASCII85 encoding filter present alongside exploit delivery indicators — uncommon outside of obfuscation
-
External URI info PDF_URIPDF contains an external URL action
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://mardurasp.com/se/?fjLkWcdWofJCWzViUmCZnIBpsVLlGWmnNcUTKkGlDhFBcvCHzFeQglEvkfQLJQPyJrIHXtmLqWRwr
