T1566.001 Spearphishing Attachment

The PDF file contains a heuristic indicating an external URI, specifically pointing to 'irlanc.ru'. The document body, though heavily obfuscated, contains text related to Ghana, likely a lure. The presence of an external URI and the ClamAV detection strongly suggest a phishing or malware distribution attempt. No scripts were extracted from this sample.
