MITRE ATT&CK

T1059.001 PowerShell T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains embedded JavaScript, including an eval() call, which is a strong indicator of malicious intent. The JavaScript is likely used to redirect the user to a malicious site, as suggested by the presence of a URI heuristic pointing to a fake IRS page. The obfuscated nature of the JavaScript and the high risk score further support this assessment. No specific malware family could be identified.

Heuristics 6

eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
AcroForm button with action trigger low PDF_ACROFORM_BUTTON

PDF contains a /Btn form field together with a SubmitForm/URI/Launch/JS trigger — this is the building block of fake 'Download' or 'Open' button overlays used in PDF phishing lures
External URI low PDF_URI

PDF contains an external URL action
