Attachment: PDF Grant Payment lure with embedded link

Description

Inbound messages carrying a PDF attachment that references a 'Grant Payment Development' RFP or bid solicitation, often sent from compromised or spoofed education-sector (.k12, .esc) accounts. The PDF contains an embedded URL, consistent with a redirect to a credential-harvesting or malicious landing page disguised as bid documentation.
