This is from a story that ran in today's JoonAng Daily:
The Cyber Terror Response Center in Gyeonggi said the gang used a DDOS attack to infect 11,000 computers at 700 PC rooms across the country.
Police said Yu bought the "Netbot Attacker" program from a Chinese hacker last November, then sold copies online to Kim and others. The gang broke into the administrative systems of the PC rooms and installed the virus in their computers to allow them to see the hands of poker opponents.
According to the story, the 33 hackers cheated online poker players out of 55 million won, the equivalent on about $45,265. I'm sure the reporter meant that the attacker's used bots designed for DDOS attacks to infect the PCs, not that the PCs were infected through a DDOS attack.
Now, these bots are commonly used to launch attacks that swamp Web sites and servers with so much traffic that they can't keep up with requests and either become painfully slow or crash until the attack can be stopped or mitigated. However, one an end point is infected with a bot, that bot can be often used to download other types of attack software, or do other things on the system: which is apparently what these attackers chose to do with their poker cheats.
Online gaming is a popular target for online attacks, but usually it's the gaming site owner that is targeted, not the players. I wrote about such attacks in a story, Extortion Online, in late 2004.
In those threats, botnet operators were threatening to use their networks to make the gaming sites unavailable - unless they were paid $100,000 annually.
