MITRE ATT&CK

T1059.005 Visual Basic for Applications T1566.001 Spearphishing Attachment

The file is an RTF document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. ClamAV detected the file as Doc.Trojan.Thus-8. The document body discusses Barack Obama, likely as a lure to engage the reader. No specific IOCs like URLs or hashes were extracted, but the presence of macros and the ClamAV detection strongly indicate malicious intent.
