what can i guess is that the spider is in Salticiade family. The genus probably Siler.
I agree. Siler glaucus looks common with a wide enough range but there is a Siler pulcher listed for Malaysia. The only paper the World Spider Catalog offers for it (Simon, 1901k) includes no pictures and a description written in Latin, I ran it through Google translate but that didn’t help me much in ruling it out. 🙂
