    Scope Expansion

    Hi you all, this is MJ (Myoungjae Lee), in charge of security at LINE. I am back with a report on running the LINE Security Bug Bounty Program for the first half of 2017. For those of you who are new to this program, the purpose of this program is to provide LINE users the most secure service possible by letting external security researchers submit bug (vulnerability) reports which we would then immediately fix. Since our official launch of the program on June 2, 2016, we have expanded the program scope to include the following:

    • LINE: Chrome version and Windows 10 Mobile version
    • Website: LINE STORE, LINE NEWS, LINE MUSIC, and LINE LIVE
    • For those of you who are interested, check the press release on the program scope expansion.

  • BigDB - an ad data pipeline for LINE
    Jongkyu Lim, Joonghoon Shin 2017.07.12

    Jongkyu Lim: Jongkyu Lim is responsible for processing ads data. Joonghoon Shin: Joonghoon Shin develops ads data platform in LINE.

    Before we begin

    Hello, we are Jongkyu Lim and Joonghoon Shin responsible for processing of ads data and development of ads platform in LINE. In this blog post, I'd like to talk about BigDB: a big data processing pipeline for LINE ads. I'll go into detail about how BigDB came to be, what BigDB is, how it's structured, what it does, and what use cases it has.

    How BigDB came to be

    As we gather data from various services that are growing in size, the size of the data grows larger as well, making it difficult to properly use them for analysis. Up until now, we've used several open solutions that support big data to tackle this problem. While using several of these open solutions that have different strengths and weaknesses, we felt the need for a more simple and standardized way to collect, process, and look up data. And that is where the idea for BigDB began. Below are some of the key features we had in mind for BigDB.

    Introducing BigDB

    What is BigDB

    BigDB is a big data processing pipeline for LINE ads. It can collect, reprocess, and look up data. LINE ads are analyzed in two ways: The first is in real-time whenever an ad is shown to a user. The second is batch analysis, where events are collected and analyzed after a set time, such as hourly or daily. BigDB fluidly provides the data used for analysis. Sometimes combining time series and static data if necessary.

  • Outcomes of the LINE Security Bug Bounty Program

    About the LINE Security Bug Bounty Program

    Hello, my name is Lee Myoung Jae (MJ) and I'm in charge of security at LINE. In this post I'm going to talk about the LINE Security Bug Bounty Program and the results of the program in 2016. The LINE Security Bug Bounty Program is an ongoing program to make the LINE app more secure for our users by letting external engineers submit bug (vulnerability) reports which we would then immediately fix.

    We first conducted a trial run of the program called the LINE Bug Bounty Program from August 24 to September 23 in 2015. Based on our experience from that trial, we made various changes to create an improved bug bounty program for 2016. And on June 2, 2016, we launched the new and improved LINE Security Bug Bounty Program.
