īandook has been launched by starting iexplore.exe and replacing it with Bandook's payload. exe and use process hollowing to inject it into a new process. Īzorult can decrypt the payload into memory, create a new suspended process of itself, then inject a decrypted payload to the new process and resume new process execution. Īstaroth can create a new process in a suspended state from a targeted legitimate process in order to unmap its memory and replace it with malicious code. However, execution via process hollowing may also evade detection from security products since the execution is masked under a legitimate process.Īgent Tesla has used process hollowing to create and manipulate processes through sections of unmapped memory by reallocating that space with its malicious code. This behavior will likely not result in elevated privileges since the injected process was spawned from (and thus inherits the security context) of the injecting process. This is very similar to Thread Local Storage but creates a new process rather than targeting an existing process. At this point the process can be unmapped using APIs calls such as ZwUnmapViewOfSection or NtUnmapViewOfSection before being written to, realigned to the injected code, and resumed via VirtualAllocEx, WriteProcessMemory, SetThreadContext, then ResumeThread respectively. A victim process can be created with native Windows API calls such as CreateProcess, which includes a flag to suspend the processes primary thread. Process hollowing is commonly performed by creating a process in a suspended state then unmapping/hollowing its memory, which can then be replaced with malicious code. Process hollowing is a method of executing arbitrary code in the address space of a separate live process. Hover over the file you’d like to prioritize.Adversaries may inject malicious code into suspended and hollowed processes in order to evade process-based defenses.If files and folders are syncing, they’ll show in the order they’ll sync next.Dropbox Backup users will see Sync and backups instead.Click the Sync history tab near the top.Click the Dropbox icon in your notification center (Windows)or menu bar (Mac).How to change the order your files and folders sync in Learn about the different sync icons and what they mean.
