Trying to renovate the kitchen a bit and now it's time to put up some IKEA cabinets.
The problem is that I'm not quite sure how to mount the wall cabinets so that they are secure.
The walls seem to be made of some form of masonite board at the core, about 1cm thick, from 1970 when the house was built, and on top of these, there are new 13mm plasterboards.
What type of screws should I use to mount the wall cabinets so they don't fall down?
Eternally grateful for any help here since I don't know anything about this.

I would have put plywood or OSB board behind the plaster for the masonite and the plaster does not hold a full wall cabinet. And I assume the studs are cc60 so the studs can be hard to hit but that is also an option..

Whether the cabinets stay up or not depends more on what you screw into than what you screw with. But if you consider the surface to be solid, for gypsum and loose fiberboards, you should use "molly." However, I would try to find the studs to ensure a safer night's sleep.
I have set up some cabinets that are screwed into 10mm masonite, but it can be questionable when it's Ikea cabinets with only two attachment points...
Fully threaded coarse screws grip well otherwise.

Horizontal 21x70 nailed securely into the wall studs. One at the top, at an appropriate height for attachment, one at the bottom just to maintain the distance. Then a trim piece to cover up.
If you screw into hardboard, you (or someone else in the family) are likely to have it fall on your head pretty quickly. The best option is to have cross studs in the wall, but it seems you have already moved past that possibility.

I am renovating and initially, the plan was for the carpenters to install the kitchen, but partly they were short on time and I don't have time to wait any longer, and then it didn't seem like too difficult a project to take on myself, I thought.
However, I am/was quite uncertain about whether masonite/gypsum can support the wall cabinets because the masonite itself is so porous.
Originally, the wall was only made of masonite boards, it was the carpenters who screwed on the gypsum boards when they redid the kitchen and prepared for their installation.
So a coarse fully-threaded screw should hold, right?
Or should I go with molly to be sure?

Since they're IKEA cabinets and you only have two mounting points per cabinet, the question is whether you should use double molly instead.
If you have access above the cabinets and this will then be hidden with ceiling connection, you can always put some construction brackets at several places between the top of the cabinet and the wall...
As an extra safety measure...
The 10mm masonite in the walls is quite compact compared to "regular" masonite...

Double molly, what is it?
I think I've only seen regular molly.
It's just 4 cabinets that need to go up: two 60-cabinets, one 40-cabinet, and a corner cabinet (60) so hopefully, I can hit a few studs.
Otherwise, it might be safest to do as firren159 suggests and nail up a couple of cross braces.

Place a thin strip inside the cabinet that you screw in from the outside of the cabinet before mounting it. Now you can add as many mollys as you like and hit the studs with a regular screw. My old kitchen (built in '69) was done this way. Of course, you paint the strip white.
