Early in the morning of June 26, 2018, Andrew Sampson , CEO of the Rainway operating company, noticed that an abnormal amount of error report was expelled from the server, over 380,000. As a result of the investigation, it turned out that there was evidence that some user's Rainway application was trying to connect to various advertising platforms. Because Rainway had content loaded only to registered domains, requests from advertisement related servers were automatically refused connection, and some users rainway had errors every time.

Further investigation also showed that all Rainway users infected with malware were playing "Fort Knight" and the infected users had installed the "Fort Knight" cheat tool. The cheat tool is an illegal program that makes the balance in the game greatly out of control, such as improperly increasing the currency in the game or supplementing the sniper accuracy in the game. Such a cheat tool seems to be a thing that only advertising movies come out like mountains when searching on YouTube and Twitter, and the staff of Rainway tried installing it, that the presence of malware was confirmed .

Malware infecting when installing cheat tool will install root certificate on infected PC. Then we set up all web traffic of the PC to be done through the proxy and do man- in-the- middle attacks . Specifically, it displays the pre-set fraud advertisement on the website you are browsing.

The Rainway team notified the company hosting the cheat tool containing malware and sent a warning to all Rainway users suspected to be infected with malware. It is said that malware was quickly deleted and can not be downloaded, but it has already been downloaded over 78,000 times.
