What you want to do is get a box of deck screws, a cheap drill, and a stud finder. Find the stud behind the cabinets, then put the deck screw through the top and bottom board at a 45° angle from the outside through the cabinet, into the stud. That will put about 6cm of screw to anchor through both the frame and back of the cabinet. Only way it’s comming down is if the wall does.
While you’re at it, replace the screws holding your door to the wall with them too, the normal screws for a door hinge are 1.5cm max, this will allow your door to sag as well as allow it to be easily knocked down. Replacing them with deck screws makes that far less likely.
