Hi folks. I obtained a pre-owned Anycubic Vyper. Alas, every print features defects in the surface as shown in the picture. It occurs in any type of material. Does anybody know the source of this type of defects?

This might be thermistor losing contact with the block or wires losing contact. It can also be the heater wires losing contact somewhere. To diagnose, you can try and wiggle the wires when you preheat the hotend and watch the temps. Then you will know what needs replacing. I once had a thermistor that was faulty, I replaced it, the problem went away.
