#### A "professional" attack { #a-professional-attack }

Of course, the attackers would not try all this by hand, they would write a program to do it, possibly with thousands or millions of tests per second. And they would get just one extra correct letter at a time.

        assertEquals("Root problem", exception.getCause().getCause().getMessage());

        verify(mockHandle, times(1)).sendrecv(any(MsrpcSamrCloseHandle.class));
