MITRE ATT&CK

Techniques & procedures

4 distinct techniques documented for this family, organized by ATT&CK tactic.

Execution

1 technique

T1106Native APIEvidence3

Using the --preset common switch will create a header/ASM pair with the following functions... NtOpenProcess... NtReadVirtualMemory... NtWriteVirtualMemory... NtAllocateVirtualMemory... NtCreateThreadEx... | SysWhispers helps with evasion by generating header/ASM files implants can use to make direct system calls... re-implementing them in your own implant can bypass the triggering of those security product hooks.

Privilege Escalation

1 technique

T1055Process InjectionEvidence1

Before-and-After Example of Classic CreateRemoteThread DLL Injection... NtAllocateVirtualMemory... NtWriteVirtualMemory... NtCreateThreadEx...

Stealth

T1027.007Dynamic API ResolutionEvidence2

By using the random syscall jump routine it is possible to avoid "mark of the syscall". The assembly stub calls a new function SW__GetRandomSyscallAddress which searches for and selects a clean syscall instruction in ntdll.dll to use.

T1562.001Disable or Modify ToolsEvidence1

SysWhispers originated as an experiment or requirement of bypassing User-land hooks placed by AV/EDR softwares... bypassing this check is the main goal of the attacker to operate undetected.
