T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a signature indicating phishing and trojan activity. It contains an embedded URL pointing to a suspicious domain, disguised as an Android Studio animation tutorial. While no scripts were explicitly extracted, the PDF structure and embedded URI heuristic suggest an attempt to redirect the user to a malicious site, likely for credential harvesting or further payload delivery.
