Bithumb, a crypto exchange, said on 28 October that personal data was leaked after an unauthorised external party abnormally accessed its in-house mobile groupware system. Yonhap and other outlets reported that the company recognised the leak on 27 October and told the Korea Internet and Security Agency (KISA) and the Personal Information Protection Commission about the breach the same day. [ 1 , 5 , 10 , 19 , 21 ]
Bithumb said it is analysing the exact scope, including the possibility that member information is included. Electronic Times reported that the company is investigating the type and scale of the leaked data and that data of general members, not only employees, may have been leaked. Newsis reported that Bithumb blocked the access right after it recognised the incident and quoted the company as saying it was moving quickly on the exact scope and items and would inform customers through its website that morning. [ 5 , 10 , 11 , 14 , 17 ]
Seoul Shinmun described groupware as an internal system where employees handle work and share information. A Korea Economic Daily headline, with no article text available, quoted Bithumb as saying its in-house messenger 'Daou Office (다우오피스)' was hacked and there was no sign of access to customer assets. Chosun Ilbo reported that personal data of 646 employees was leaked on 27 October and that the company was checking whether content exchanged on the in-house messenger included customer personal data. [ 5 , 15 , 18 ]
Outlets placed the case within a run of incidents. Chosun Ilbo reported that Daishin Securities confirmed a leak of 38,490 customers' data and that a hacking incident also occurred at Mirae Asset Global Investments, with financial authorities checking the cause and scale. Kyunghyang Shinmun said security incidents had earlier been reported at Streami (스트리미), operator of Gopax (고팍스), and at Prabaeng (프라뱅), a coin market exchange. Newsis called the Bithumb case an extension of chain cyberattacks spreading across the financial sector. [ 14 , 15 , 21 ]
Chosun Ilbo also quoted Lee Chan-jin, head of the Financial Supervisory Service, who said AI-assisted hacking methods are becoming more sophisticated and urged financial firms to invest more in security. [ 15 ]
On 29 October, a Yonhap item headlined that Bithumb's customer data leak was confirmed belatedly said customer personal data was also reportedly leaked in the in-house system hack. Only the summary was available, with no further detail. [ 24 ]
Por qué importa
Outlets placed the incident within a run of hacking cases hitting financial firms, including Daishin Securities and Mirae Asset Global Investments. Whether customer data is involved is not settled in the early reports, so the scale is still open.
