T1566.001 Spearphishing Attachment
The document presents a lure for free Robux, a virtual currency, and contains an external URI pointing to a download site. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a call-to-action button suggests a phishing or malware distribution attempt. Although no scripts were explicitly extracted, the PDF structure and embedded URLs are indicative of a malicious intent to trick users into downloading further payloads.
Machine Learning
- Nyx PDF Classifier malicious score 0.9980
Heuristics 4
-
Callback phishing phone lure medium SE_CALLBACK_LUREDocument asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) documents that carry no urgency or charge/dispute escalation.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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 http://netcdn.co/app/431946152/free-robux-2021-real-no-human-verification-game-hack
