Coupang jumps; co claims leaked customer data deleted

Shares of online retailer Coupang CPNG.N jump 11% to $25.25; stock set for highest percentage gain in over seven months

Co said on Thursday that the suspect has deleted all leaked customer information, per emailed statement

Former employee allegedly downloaded personal data of about 3,000 customers out of CPNG's 33 mln customers, which was deleted without third-party transfer

South Korea's science ministry said the incident remains under investigation and CPNG's claims have not been confirmed by authorities

Earlier this week, co has also been sued in a U.S. court in an investor class action alleging violations of securities laws

The breach, described as South Korea's worst in over a decade, compromised personal data of about 33 mln co's customers

Including session's moves, the stock had risen nearly 15% year-to-date but has dropped about 5.6% since December 1 when the news of the breach was first reported
