It has been revealed that personal information of more than 4.5 million members of 'Ttareungi,' a public bicycle service operated by the Seoul Metropolitan Government, has been leaked.
The Seoul City Facilities Corporation said it received information from the Seoul Cybercrime Investigation Team of the Seoul Metropolitan Police Agency that Ttareungi member information had been leaked due to hacking.
As a result of this incident, it is reported that a large amount of personal information, including names, phone numbers, dates of birth, and addresses, has been leaked from Ttareungi member information held by the Seoul Metropolitan Government.
The number of Ttareungi subscribers is known to be around 5 million, and the number of leaks identified so far is about 4.5 million, which may increase depending on the situation.
Previously, the Seoul Metropolitan Government said that names and resident registration numbers were not mandatory when joining Ttareungi, so this information was not leaked.
However, it appears that personal information entered voluntarily by members was included in this leak, raising concerns about the possibility of secondary damage such as identity theft or fraud.
