Riot Games reported last week that a social engineering attempt had infiltrated the systems in their software platform. Motherboard got the ransom note that was sent to Riot Games and reported that hackers demanded $10 million in exchange for keeping the stolen source code a secret and erasing it from their servers.
The LoL and TFT teams are investigating how to cheat developers who might exploit the data that was obtained to create new tools and evaluating whether any fixes are necessary to resist such nefarious attempts. According to the game creator, the game source code obtained during the security breach also includes certain unreleased features that might not make it to the release stage.
Hackers gave Riot Games two sizable PDFs as proof, claiming that they would demonstrate their access to Packman and the League of Legends source code. These files were also obtained by Motherboard, and they seem to display directories connected to the game's code. According to the ransom message, the hackers threatened to remove the code from their servers in exchange for payment and give insight into how the intrusion occurred and offer guidance on preventing future breaches.
The hackers indicated Riot Games could contact them through a Telegram chat, and they provided a link to that chat in the post. The motherboard has joined this channel. Its members contained usernames that corresponded to the names of Riot Games personnel.
No player or user information was taken during the attempt, as per Riot, but the company warned that it would take some time to adequately protect the systems and that patches might be delayed. The breach is the subject of an investigation by Riot Games. It appears that the attacker did not utilize ransomware but instead concentrated on stealing source code so they could demand money from the business.
