How to participate in the TVING class action lawsuit with Law Firm Sedam? Guidance, retainer fees, personal information leakage inquiry, CI

Following the Tving personal information leak, there is a growing movement among affected users to file class action lawsuits. In particular, Law Firm Sedam is garnering attention by recruiting plaintiffs through a method that allows participation without an upfront fee.

 

This incident is raising greater concerns as it is known that not only IDs or emails were leaked, but also CI and DI, which are used for personal identification online.

 

 

1. TVING Personal Information Leak: What Information Was Stolen?

TVING announced that there was unauthorized external access to a database containing personal information in early June 2026.

 

 

The leaked data included member IDs, names, dates of birth, gender, CI, DI, parts of mobile phone numbers, parts of email addresses, refund account numbers, and passwords. While it is reported that passwords were encrypted using one-way encryption and account numbers and parts of email addresses were encrypted or masked, user anxiety has increased due to the wide range of leaked information.

 

The most notable item is CI. CI stands for Linked Information and is a unique value used to identify the same user across various online services. Although it is not information entered directly like a Resident Registration Number, it is referred to as an "online identifier" because it is generated during the identity verification process and can link users across multiple services.

 

Because it cannot be easily changed like a password once leaked, the risk of secondary damage such as smishing, voice phishing, and account theft can increase if combined with names, dates of birth, mobile phone numbers, etc.

 

 

2. How do I check for a Tving personal information leak?

It is safest to check whether your personal information has been leaked on the official TVING website.

 

 

Rather than immediately clicking on links received via text message or KakaoTalk, it is better to access the official TVING website directly through a search or the browser address bar. This is because phishing text messages impersonating law firms, companies, and institutions may increase following personal information leaks.

 

To check, visit the official TVING website Log in, access MY Menu or the personal information leakage incident notification page, and select the Search button. You just need to proceed in order. The search results will display the leaked items that apply to you.

 

It is advisable to capture this screen for future legal action or inquiries. Saving the leak notification text message, email, TVING announcement screen, and the leaked item lookup screen together can be used as evidence.

 

 

3. How to participate in Law Firm Sedam?

Proof of Tving subscription can be prepared using data leak notification text messages, leak inquiry screens, the subscribed email, or payment history. It is stated that all procedures can be completed remotely.

 

 

4. What are Sedam's retainer fees and success fees?

Law firm Sedam 0 won down payment is putting forward.

It is also stated that incidental litigation costs, such as court filing fees and service fees, are not charged separately. Another point frequently considered by participants is that no costs are charged to the client in the event of a loss.

 

 

However, if there is an amount that was actually successfully recovered in the lawsuit, of that amount 20% success fee It is stated that settlement is made accordingly. For example, if compensation or settlement money is paid, 20% of it is structured to be deducted as a success fee.

 

Therefore, even if it is called a “free lawsuit,” it is not entirely free of costs; it is more accurate to understand it as a system where there is no initial payment and a success fee is paid when there is a result.

Currently, the law firms frequently mentioned in connection with the Tving personal information leak are Sedam Law Firm and Jihyang Law Firm. Sedam is known to have a structure of 0 won in retainer fees and 20% in success fees, while Jihyang is reported to have filed a lawsuit claiming 300,000 won per person after receiving a participation fee of 10,000 won.

 

Jihyang also advises that the law firm handles the procedures and responsibilities to ensure that no separate burden is incurred by the participants in the event of a loss.

 

It is difficult to definitively say which is better. If you wish to participate without the burden of initial costs, the Sedam method may be less burdensome, and if you want to compare billing amounts and success fee structures, you can also check the Jihyang guide.

 

It is important not to apply based solely on links from online cafes or blogs, but to必ず verify the requirements on the relevant law firm's official website or application page.
