MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.001 Malicious Link
T1059.001 PowerShell
The PDF file contains embedded links, one of which points to a known malicious redirector. The document body, though heavily obfuscated, contains text related to 'free lap harp sheet music for beginners', suggesting a lure. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' confirms the redirection to malicious infrastructure, and 'PDF_SEO_LINK_FARM' indicates a large number of outbound links, likely for SEO manipulation or to host further malicious content. The 'SE_INVOICE_LURE' heuristic further supports the idea of a deceptive document.
Heuristics 4
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
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.
-
Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
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://ttraff.cc/pify?keyword=free+lap+harp+sheet+music+for+beginners
