New ‘SpectralBlur’ macOS Backdoor Related to North Korea


A group of security researchers have conducted an in-depth analysis of SpectralBlur, a novel backdoor for MacOS that seems to be associated with the KandyKorn malware family, which was recently identified as originating from North Korea.

Lesnewich compared the backdoor to KandyKorn, a macOS backdoor that Lazarus had been observed utilizing in recent attacks.
