MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF file contains a critical heuristic indicating it's a malicious redirector link, pointing to 'https://ttraff.ru/pify?keyword=collections.+sort+not+working+android'. It also exhibits characteristics of a PDF link farm, with numerous embedded links, many of which are hosted on Shopify. The ClamAV detection further confirms its malicious nature. The document body contains the string 'Collections. sort not working android' which appears to be a lure for the malicious link.

Heuristics 4

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF 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_FARM
    Small 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.
