Signature (11cnts)

Level Description
danger Executed a process and injected code into it
watch Allocates execute permission to another process indicative of possible code injection
watch Code injection by writing an executable or DLL to the memory of another process
watch Detects Avast Antivirus through the presence of a library
watch Potential code injection by writing to the memory of another process
watch Resumed a suspended thread in a remote process potentially indicative of process injection
watch Used NtSetContextThread to modify a thread in a remote process indicative of process injection
notice One or more potentially interesting buffers were extracted
notice The binary likely contains encrypted or compressed data indicative of a packer
notice Yara rule detected in process memory
info The executable contains unknown PE section names indicative of a packer (could be a false positive)
