Apple’s macOS has long been considered a more secure operating system. Still, a recent study by security analysis firm Bitdefender found that malware JokeySpy targets macOS systems for the attack.
Mac researchers at Bitdefender accidentally discovered a set of files with backdoor functionality during routine inspection and maintenance, which are part of some more sophisticated malware toolkit. Although the researchers have analyzed the outgoing portion of the malware, they are still working to track down the complete malware toolkit.
It is understood that the malware was first uploaded anonymously to the VirusTotal website on April 18 of this year and began spreading across the network, with three variants (JokeySpy B/C/D) now appearing.
The researchers note that the malware is written in Python and that the variants are very similar and share the same feature set, with the most significant difference being the order of the two Python import libraries. They also believe that the malware flowing is only part of the overall malware package and that more attacks targeting the macOS platform may emerge.
This discovery has drawn widespread attention and alerted macOS users to be more vigilant. Users are advised to promptly update their operating systems and security software and avoid downloading files from unknown sources to protect their personal data and system security. Meanwhile, security vendors strengthen their analysis and protective measures against such malware to ensure users’ online safety.
For Apple macOS, the emergence of the JokeySpy malware is another reminder that even relatively safe operating systems are not absolute havens and that both users and vendors need to remain vigilant and strengthen security measures.
