Steam is an Internet-based digital distribution platform developed by Valve Corporation offering digital rights management (DRM), multiplayer, and social networking. Steam provides the user with installation and automatic updating of games on multiple computers, and community features such as friends lists and groups, cloud saving, and in-game voice and chat functionality. It is highly popular among gamers around the world. The hack attack was fairly simple and anybody who Steam gamers user name could exploit the bug. Elm Hoe, a Steam gamer and YouTuber, help spread word of the breach on July 25 when he posted a video which is given below :
Once the hacker knew the Steam gamers account name, they simply had to visit Steam’s Lost Password page, enter the targeted account and simply click Continue when asked to enter their email verification. Steam took its services offline on 26 July while Valve, which owns Steam, worked on the issue. Right now the security hole appears to have been fixed but Valve has not issued any comment on the bug or how it was fixed. One report from a Steam user suggested that attackers may have been able to bypass Steam Guard without hacking an e-mail account however the same has not been confirmed either by Valve or Steam.
