The source analyzes XML malware attributed to Kimsuky that uses PowerShell to download and execute an external script with a hidden window. The XML content contains hex-encoded PE data that is reconstructed into a binary, saved as xBqz.mp3, renamed as an executable, and launched without opening a new window. The payload creates heap memory, copies and XOR-decrypts data with a 16-byte key, validates decrypted values, parses PE structures through the PEB loader list, and resolves functions by hashing module entries. The author notes that sandbox results were inconsistent, but the sample was still treated as high-risk Kimsuky-delivered XML malware.
