T1566.001 Spearphishing Attachment
The sample is identified as malicious by ClamAV and an ML classifier, with heuristics indicating it functions as a link farm on compromised WordPress sites and disposable hosting. The embedded URLs, such as https://oniceh.ru/uplcv?utm_term=undang+undang+ketenagakerjaan+thr+pdf, likely lead to phishing or malware distribution pages. Although no scripts were explicitly extracted, the PDF structure and URL patterns strongly suggest a phishing or credential harvesting attempt.

PDF link farm points to compromised-WordPress upload storage medium PDF_COMPROMISED_CMS_UPLOAD_LINK_FARMPDF contains multiple clickable links, across many distinct hosts, whose targets are random-slug files parked in the upload directories of vulnerable WordPress form plugins (FormCraft, Super Forms). This is the hallmark of the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains hosted on compromised sites. The PDF itself carries no exploit — the risk is the linked destinations.
-
Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARMSmall PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.
