SentinelOne reviewed JokerSpy activity involving macOS-focused spyware, cross-platform Python backdoors, and a suspected Java-based QRLog infection vector tied to a trojanized QR code generator. QRLog wrote and executed payloads after contacting hxxps://www.git-hub.me/view.php, while shared.dat used matching GITHUB_REQ and GITHUB_RES strings and could stage AppleAccount payloads on macOS. The sh.py backdoor used ~/Public/Safari/sar.dat for configuration, could beacon as often as every five seconds, and supported surveillance, command execution, data exfiltration, and file deletion; Elastic observed app.influmarket[.]org as C2 in a Japanese cryptocurrency exchange intrusion. The macOS xcc component imitated XProtect naming, checked user activity and privacy permissions, and was observed alongside SwiftBelt deployment, indicating multi-language tooling across Java, Python, and Swift for financially relevant targets.
