T1059.005 Visual Basic for Applications
T1059.001 PowerShell
T1566.002 Spearphishing Attachment
T1140 Deobfuscate/Decode Files or Information
The sample is a macro-enabled Excel file that exhibits characteristics of a downloader. The Workbook_Open macro and CreateObject calls suggest the execution of malicious code upon opening. The presence of an appended payload and numerous suspicious URLs indicates an attempt to download and execute further malicious content, likely for a broader attack.
Heuristics 10
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 224,256 bytes but its declared streams total only 110,123 bytes — 114,133 bytes (51%) live in unallocated sector slack. This is the canonical hiding place for pre-macro-era Office exploit payloads (XOR-encoded shellcode reached via a parser pointer-corruption bug in the document structure).
-
OLE file has appended executable-looking payload bytes high OLE_APPENDED_PAYLOADOLE compound file contains a large high-entropy region beyond the declared major streams and that region includes shellcode, PE, or loader API markers. This is a payload-carrier signal, not a specific CVE attribution by itself.
-
Workbook_Open macro high OLE_VBA_WBOPENWorkbook_Open macro
-
CreateObject call high OLE_VBA_CREATEOBJCreateObject call
-
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXECCompiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
-
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGEOne 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.
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
-
Environ() call (env variable access) low OLE_VBA_ENVIRONEnviron() call (env variable access)
-
Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — context-specific rules above attribute URLs they actually evaluated; this rule lists URLs that were present in the bytes but were not otherwise tied to a specific finding.URL https://cooI��Do2%j(a�}*�;et/wp-content/thr�/���
