DoubleAgent is a new Zero-Day technique for injecting code and maintaining persistence on a machine (i.e. auto-run).

DoubleAgent can exploit:

Every Windows version (Windows XP to Windows 10)
Every Windows architecture (x86 and x64)
Every Windows user (SYSTEM/Admin/etc.)
Every target process, including privileged processes (OS/Antivirus/etc.)

DoubleAgent exploits a 15 years old undocumented legitimate feature of Windows and therefore cannot be patched.
