CrescentCore is malicious software, also referred to as OSX/CrescentCore. Its main purpose is to install fake system optimization tools, third-party extensions for Safari browser, or even rogue security apps specifically tailored for Mac. CrescentCore is promoted by means of fictitious Adobe Flash Player update notifications or some other dubious software updates.
The problem with CrescentCore is that it is poorly detected by today’s major anti-virus programs. The malware is regularly updated and often finds leaks to inject Macs that are not furnished with the powerful security software preventing the attack.

Once the fake Adobe Flash Player alert is launched, CrescentCore inspects whether it works on a virtual machine. Additionally, it checks if there is any anti-virus software active on Mac. CrescentCore does not infect the systems running on virtual machines (VMs) or Macs that have anti-virus programs in place. Once the checkup is made and no VMs or anti-viruses are discovered, CrescentCore may install rogue anti-virus software called Advanced Mac Cleanup, or some other malware into Safari browser.
According to the analysis performed by several malware researchers, CrescentCore has several versions. They may cause different consequences on the attacked Macs depending on the regional settings. Therefore, some other malicious programs may be installed in addition to the ones mentioned above. The summary regarding CrescentCore is that this is the malware you should immediately delete to stop the damage it spreads.
