T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a link to a redirector URL, which is a common tactic for delivering malware. The document body and heuristics indicate a lure for software, specifically 'adobe illustrator cs4 portable kuyha', to entice users to click the link. The PDF also contains a link farm, suggesting an attempt to manipulate search engine results or distribute multiple malicious links. The presence of a password-protected archive lure suggests the actual payload is likely encrypted.
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
-
