T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains a large number of external links, many of which are presented as 'how-to' guides for hacking popular games. The ML classifier strongly indicated maliciousness, and the PDF structure suggests a link farm designed to distribute malicious content or lead to phishing pages. The presence of a download button lure and callback phishing context further supports a malicious intent.
Machine Learning
- Nyx PDF Classifier malicious score 0.9980
Heuristics 5
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
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/how-to-hack-into-any-roblox-account-2021-game-hack PDF link annotation
