I don't have the document since I just inhereted it from the previous guy, but docs available online doesn't say anything.
While on wiki, it says some vulnerabilities on vista which maybe from one of my clients. I just wanted to know more about this type of attack and make sure that none of my clients will be affected nor any of them is the source.

In my logs I find entries about attacks on my system. I know IP addresses, I know date and time and I know what they tried to do. So what's the best I can do now? Tell everybody that there are cybercriminals on that network? Write an email to their admin? Anything else? (10 Replies)

xselectinput
XSelectInput(3X11) XLIB FUNCTIONS XSelectInput(3X11)
NAME
XSelectInput - select input events
SYNTAX
XSelectInput(display, w, event_mask)
Display *display;
Window w;
long event_mask;
ARGUMENTS
display Specifies the connection to the X server.
event_mask
Specifies the event mask.
w Specifies the window whose events you are interested in.
DESCRIPTION
The XSelectInput function requests that the X server report the events associated with the specified event mask. Initially, X will not
report any of these events. Events are reported relative to a window. If a window is not interested in a device event, it usually propa-
gates to the closest ancestor that is interested, unless the do_not_propagate mask prohibits it.
Setting the event-mask attribute of a window overrides any previous call for the same window but not for other clients. Multiple clients
can select for the same events on the same window with the following restrictions:
o Multiple clients can select events on the same window because their event masks are disjoint. When the X server generates an event,
it reports it to all interested clients.
o Only one client at a time can select CirculateRequest, ConfigureRequest, or MapRequest events, which are associated with the event
mask SubstructureRedirectMask.
o Only one client at a time can select a ResizeRequest event, which is associated with the event mask ResizeRedirectMask.
o Only one client at a time can select a ButtonPress event, which is associated with the event mask ButtonPressMask.
The server reports the event to all interested clients.
XSelectInput can generate a BadWindow error.
DIAGNOSTICS
BadWindow A value for a Window argument does not name a defined Window.
