MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a signature indicating it is a phishing trojan. It contains an embedded URI pointing to a URL that suggests downloading Android Studio for PC, likely a lure for users seeking software. No scripts were extracted from this sample, but the presence of the malicious URI and the ClamAV detection strongly suggest a phishing or malware distribution attempt.
