MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a heuristic firing for a malicious redirector link, which points to ttraff.ru. The document body also contains this URL and a large number of other URLs, many hosted on cdn.shopify.com, suggesting a link farm for SEO poisoning. The 'SE_PASSWORD_ARCHIVE_LURE' heuristic indicates the document may be instructing the user to open a password-protected archive, a common tactic to bypass gateway security. The primary malicious URL is https://ttraff.ru/pify?keyword=password+protect+pdf+acrobat+reader+2017, which is likely used to redirect to a malicious payload or phishing page.
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.
-
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
-
