Crisis Trojan
Crisis Trojan Can infect VMware machines, Windows ,Mac.
When it was first discovered last month, researchers indicated the Crisis Trojan was a unique piece of malware in the way it can infiltrate both Windows- and Mac-based systems. It turns out that was only the beginning.
Spread
Crisis, also known as Morcut, is a malicious rootkit which infects both Windows and Mac OS X machines using a fake Adobe Flash Player installer.
The installer was actually a Java archive (JAR) file which had been digitally signed by VeriSign.
The JAR file contained two executables, one to infect Mac OS X and the other to infect Windows. The malware checks the operating system of the infected machine and drops the appropriate executable to open a backdoor onto the compromised computer.
