Chief among its methods to evade detection and stay under the radar included a delay of 14 days before accessing its command-and-control servers and the facility to execute malicious binaries directly from memory. MyloBot also leverages a technique called process hollowing , wherein the attack code is injected into a suspended and hollowed process in order to circumvent process-based defenses. This is achieved by unmapping the memory allocated to the live process and replacing it with the arbitrary code to be executed, in this case a decod...
