DIVER OSINT CTF 2026 “arcade”

Solution

A reverse image search of the object outside the window identified the building through an article about Far Eastern Xinyi A13 (遠百信義A13). However, the store information alone did not reveal where inside the building the photo was taken or whether there was an arcade there.

I then ran a reverse image search of the game cabinet and identified it as 秘密的偶像公主. Checking the store list confirmed that the game was installed at “FUNBOX：信義遠東” in Far Eastern Xinyi A13.
