T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, with one specifically pointing to a search result for 'lenovo t430 charger replacement'. This suggests a phishing or SEO-based lure to direct users to potentially malicious sites. The presence of a large number of external links, including a PDF link farm, and ClamAV detection as 'Pdf.Phishing.Trojan' strongly indicate malicious intent. No scripts were extracted, but the PDF structure itself is used to host these links.
