MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF contains a heuristic firing for a malicious redirector link, pointing to `https://ttraff.cc/pify?keyword=chromosome+mutation+worksheet+answer+key`. This URL is presented within the document body, disguised as a worksheet answer key. The PDF also contains a large number of external links, many hosted on Shopify, suggesting a link farm for SEO manipulation or to obscure the malicious redirector. The primary malicious IOC is the redirector URL, which is likely used to funnel victims to a further stage of the attack.
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.
-
