Bringing process injection into view(s): exploiting all macOS apps using nib files · Sector 7
In a previous blog post we described a process injection vulnerability affecting all AppKit-based macOS applications. This research was presented at Black Hat USA 2022, DEF CON 30 and Objective by the Sea v5. This vulnerability was actually the second universal process injection vulnerability we reported to Apple, but it was fixed earlier than the first. Because it shared some parts of the exploit chain with the first one, there were a few steps we had to skip in the earlier post and the presentations. Now that the first vulnerability has been fixed in macOS 13.0 (Ventura) and improved in macOS 14.0 (Sonoma), we can detail the first one and thereby fill in the blanks of the previous post. This vulnerability was independently found by Adam Chester and written up here under the name “DirtyNIB”. While the exploit chain demonstrated by Adam shares a lot of similarity to ours, our attacks trigger automatically and do not require a user to click a button, making them a lot more stealthy. Therefore we decided to publish our own version of this write-up as well.

Analyzing DPRK's SpectralBlur
In both his twitter (err, X) thread and in a subsequent posting he provided a comprehensive background and triage of the malware dubbed SpectralBlur. In terms of its capabilities he noted: SpectralBlur is a moderately capable backdoor, that can upload/download files, run a shell, update its configuration, delete files, hibernate or sleep, based on commands issued from the C2. -Greg He also pointed out similarities to/overlaps with the DPRK malware known as KandyKorn (that we covered in our “Mac Malware of 2024” report), while also pointing out there was differences, leading him to conclude: We can see some similarities ... to the KandyKorn. But these feel like families developed by different folks with the same sort of requirements. -Greg
