ObjCShellz Malware: A New Threat to Mac Security
Mac users beware! Researchers at Jamf Threat Labs have recently discovered a new malware that poses a serious threat to Mac security. This malware, known as ObjCShellz, allows hackers to gain unauthorized access and control over infected Mac devices. What’s even more concerning is that this malware is believed to be connected to the notorious BlueNoroff Advanced Persistent Threat group, which typically targets banks, cryptocurrency exchanges, and venture capitalists.
So, what exactly does ObjCShellz do? Well, it is created using the Objective-C programming language and enables hackers to execute shell commands remotely from their server, effectively giving them complete control over the infected Mac. Additionally, the malware can gather information about the Mac, such as the version of macOS it is running, and send that data back to the hacker’s server.
The Connection to BlueNoroff and Rustbucket
Jamf’s researchers have found that ObjCShellz communicates with a domain associated with the Rustbucket malware, which was discovered earlier this year. Rustbucket is linked to BlueNoroff, a state-sponsored hacking group from North Korea. Despite its simplicity, ObjCShellz is a highly functional malware that aids attackers in achieving their objectives.
It’s worth noting that at the time of Jamf’s analysis, ObjCShellz went undetected on VirusTotal, a popular website for checking files and URLs for malware. While Apple recently released macOS Sonoma 14.1.1 and Ventura 13.6.2 updates, these updates do not contain any specific security patches.
How to Protect Yourself from Malware
Given the rising threat of malware, it’s crucial for Mac users to take proactive measures to protect their devices. Apple provides built-in security features within macOS and regularly releases security patches through OS updates. It’s essential to install these updates promptly to ensure your Mac is equipped with the latest security enhancements.
When downloading software, always opt for trusted sources such as the App Store or the developer’s official website.
