Description

CrescentCore is a trojan horse disguised as an Adobe Flash Player installer. The installer comes on a .dmg file: the same kind of disk image file that can be used to install a legitimate application. The malicious file is served to unsuspecting users as a download on infected websites. First discovered in June 2019, researchers have found CrescentCore on illegal filesharing sites as well as on websites appearing in high-ranking Google search results.

CrescentCore is notable for its sophisticated anti-detection features. Once downloaded, the malware performs a scan to determine if it running inside of a virtual machine (VM), a virtualized operating system used by security researchers to study malware safely. CrescentCore also checks to see if there are any third-party anti-malware tools present on the system. If CrescentCore sees that it is in a VM or discovers an anti-malware program, it will shut down in order to avoid detection. But if it finds itself on an unprotected computer, the malware will install a LaunchAgent file, which will allow it to control system processes in the background and create an infection that will persist even after the machine is rebooted.
