MITRE ATT&CK

T1204.002 Malicious File T1059.001 PowerShell T1059.007 JavaScript

The PDF file contains embedded JavaScript and triggers an OpenAction, indicating an attempt to execute code upon opening. Critical heuristics identified exploits for CVE-2007-5659 (Collab.collectEmailInfo) and CVE-2008-2992 (util.printf), which are known vulnerabilities in Adobe Reader. These exploits likely facilitate the execution of the embedded JavaScript, which is obfuscated and suspicious. The file is therefore designed to leverage these vulnerabilities to run malicious code.

Heuristics 7

Collab.collectEmailInfo — CVE-2007-5659 critical CVE exact CVE_2007_5659

PDF JavaScript calls Collab.collectEmailInfo — CVE-2007-5659 is a buffer overflow in Adobe Reader triggered by a long argument or heap-sprayed message field passed to Collab.collectEmailInfo(). Part of a series of Acrobat JS API exploits. (matched in decompressed stream)
util.printf — CVE-2008-2992 critical CVE exact CVE_2008_2992

PDF JavaScript calls util.printf() — CVE-2008-2992 is a stack buffer overflow in Adobe Reader triggered by a long format-specifier argument. Widely exploited in the wild after disclosure. (matched in decompressed stream)
OpenAction trigger high PDF_OPENACTION

PDF has an /OpenAction — code runs automatically when opened
unescape() call high PDF_UNESCAPE

unescape() found — often used to decode shellcode in PDF JS exploits (matched inside decoded stream)
Suspicious extracted artifact high 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.
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.
