Bitdefender researchers discovered a set of malicious files with backdoor capabilities that are suspected to be part of a sophisticated toolkit designed to target Apple macOS systems.

The investigation is still ongoing, the experts pointed out that the samples are still largely undetected.

The researchers analyzed a total of four samples that were uploaded to VirusTotal, with the earliest sample that was uploaded by an anonymous actor to the platform on April 18, 2023. The remaining ones have been uploaded by the victim.
