T1059.001 PowerShell
T1204.002 Malicious File
The PDF file contains embedded JavaScript and a large number of external links, many of which point to other PDF files. The document body text and a specific heuristic indicate a lure related to a 'payroll system in excel format free'. The embedded JavaScript likely facilitates the download or redirection to malicious content, and the numerous external links suggest a link farm or a method to distribute further malicious payloads. The primary URL http://lapen.us/uploads/1/3/0/9/130969465/130969465.html#payroll+system+in+excel+format+free is a strong indicator of the initial lure.
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.
-
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.
-
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://lapen.us/uploads/1/3/0/9/130969465/130969465.html#payroll+system+in+excel+format+free
