T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains numerous links, many of which point to SEO-optimized PDF files hosted on Shopify. The primary lure appears to be a link to a game, which redirects through `ttraff.ru/pify` to a malicious URL. This infrastructure is indicative of a phishing or scam campaign designed to drive traffic to malicious sites. The presence of a PHP webshell heuristic suggests potential for further malicious activity if the redirected site is compromised.

Heuristics 6
-
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.
-
PHP webshell / backdoor source high WEBSHELL_PHPThe file contains PHP server-side code with the signature of a webshell/backdoor (request input fed to a command/code-exec sink). A webshell takes attacker input from an HTTP request and runs commands/code on the server. Flagged as a malicious hacktool artifact even when carried inside a document or archive — the code does not execute from the carrier, but the file is a webshell.
-
Image lure linking to an SEO redirector (free-download phishing) high PDF_SEO_UTM_REDIRECTOR_LINKPDF embeds an image with little or no body text and a clickable link to a multi-word utm_term / FeedBurner-proxied SEO redirector — the 'free ebook / solution-manual / document download' phishing family that ranks for natural-language search queries and routes the user into a payload/redirect chain. The PDF carries no exploit; the risk is the linked destination. Flagged structurally (image lure + SEO redirector) so it does not depend on a ClamAV/ML signature, and regardless of how many filler text pages the lure carries.
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://ttraff.ru/pify?keyword=bubble+trouble+3+game In PDF document text
