MITRE ATT&CK

T1059.007 JavaScript T1566.001 Spearphishing Attachment

The PDF contains obfuscated JavaScript that utilizes the getURL function to redirect the user to a suspicious domain. The script decodes a URL, which is then used to initiate a connection to 'globalsearchings.com'. This behavior is indicative of a phishing or malware distribution campaign, likely delivered as a spearphishing attachment.

Heuristics 6

JavaScript action low 3 related findings PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Search-themed obfuscated getURL redirector campaign critical PDF_JS_SEARCH_REDIRECTOR_GETURL_CAMPAIGN

PDF document-level JavaScript automatically opens a known search-themed redirector campaign URL from a percent-escaped getURL() target. This is malicious redirect-carrier behavior, not evidence of a PDF parser CVE.
Obfuscated document JavaScript getURL redirector high PDF_JS_OBFUSCATED_GETURL_REDIRECTOR

PDF document-level JavaScript automatically calls getURL() on an HTTP(S) destination hidden behind percent escapes. The decoded path is a redirector-style endpoint such as /in.cgi or /go.php. This is malicious routing behavior rather than a PDF parser CVE.
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.
Suspicious extracted artifact medium EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
Embedded URL info EMBEDDED_URL

One 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.
