Trojan.MacOS.Morcut.J Description

Morcut.J is a Trojan horse malware infection that affects computers running macOS. It came under the radar of researchers a few years ago with several analyzed samples. This type of malware installs on target devices in a stealthy manner, typically disguised as some useful tool or software program. Upon successful infiltration, Morcut.J Trojan performs a series of malicious activities that can cause severe cybersecurity issues on attacked Mac systems. Several cases have been reported in which users downloaded and installed Morcut.J believing that it is a Flash Player update. In other attacks, cyber crooks have injected the Trojan horse payload into spam email attachments that looked like legit documents.

After installation, Morcut.J tries to get full control over vulnerable Mac devices. Among its malicious actions is stealing sensitive user data, like login details for various online accounts and bank/credit card data. Morcut.J can also attack password management applications and extract entire keychains from there. A widespread method of harvesting login details from online banking portals is by generating a virtual layer over the legit website. In many cases, Trojans also create a backdoor, which opens the way for more severe malware threats, like ransomware.

Trojan horses like Morcut.J operate silently in the background, and as their goal is to remain unnoticed as long as possible, they often have advanced anti-detection features. The removal process can also be lengthy and complicated for inexperienced users. Therefore, experts recommend using a reliable anti-virus application to remove Morcut.J from a Mac computer.
