My company is hiring 2 people and the salary slip they showed shows a very high pay. Now, I know from another mutual friend in the previous company that these 2 guys are working from that their salary is probably 35% less. I actually called up KWSP / EPF to find out based on their EPF number and SOCSO number however they refused to let my HR team get the previous information about this. How can I make a report to get KWSP / EPF to give me historical information on their previous salary?

I was thinking of asking my friend who works in an MNC to try submit their documents saying that he wants to hire them and that he wants to do a background check. Since he works in a well established MNC, I was wondering if KWSP / EPF will disclose this information. Thank you.
