DBsense said many marketers reported impersonation calls citing their platform nicknames, and it judged that member nicknames and mobile numbers had very likely leaked through an abnormal route [1]. The company says no clear intrusion traces were found yet, is investigating with a security firm, and has reported to KISA and the PIPC [1]. DBsense asks members to change their password immediately and stresses it never calls to offer side jobs, has no official app and never asks for money, so such contacts are scams [1].
