SK Telecom's decision to replace all customers' USIM cards due to a hacking incident has drawn attention to XCURE, which is rapidly declining after hitting the upper limit for three consecutive days.

As of 9:17 a.m. on the 30th, XCURE is trading at 5,290 won, down 1,230 won (18.74%) from the previous day.

XCURE is known to be the company supplying USIM chips to SK Telecom. Recently, SK Telecom's announcement of replacing USIM cards after all customers' personal information was hacked had caused a surge in stock prices.

The decline that day appears to be due to profit-taking following a sharp rise in stock prices. XCURE recorded upper limit prices for three consecutive trading days starting on the 25th. The stock price, which was at 2,970 won on the 24th, more than doubled to 6,510 won as of the 29th.
