MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, characteristic of a link farm, designed to obscure malicious activity. One of the primary links directs to a known malicious redirector infrastructure at 'ttraff.ru'. The document body, though partially corrupted, contains text suggesting it is a 'printable 2020 august calendar pdf', a common lure for users. The presence of numerous Shopify-hosted PDFs, alongside the malicious redirector, indicates a coordinated effort to distribute malicious content.
Heuristics 3
-
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.
-
