The source analyzes a Kimsuky sample named like a Korean software security checklist for developers, using a double extension to make a VBScript look like an Excel macro file. The VBScript creates shell and file-system objects, writes large Base64 payloads under ProgramData or the Windows root, decodes one payload with certutil, launches the resulting decoy file, and runs a batch command that XOR-decodes another payload. It then executes the decoded component through regsvr32 and deletes the original script, making the lure useful for detecting developer-themed phishing, script obfuscation, Base64 staging, and living-off-the-land execution.
