[quote]Twitch.tv is a video gaming focused live streaming platform. It has more than 50 million viewers and was acquired by Amazon.com in August for nearly a billion dollars.
We recently received a report from a concerned user about malware that is being advertised via Twitch's chat feature. A Twitch-bot account bombards channels and invites viewers to participate in a weekly raffle for a chance to win things such as "Counter-Strike: Global Offensive" items.

The link provided by the Twitch-bot leads to a Java program which asks for the participant's name, e-mail address and permission to publish winner's name, but in reality, it doesn't store those anywhere.

After this message, the malware proceeds to dropping a Windows binary file and executing it to perform these commands:

• Take screenshots
• Add new friends in Steam
• Accept pending friend requests in Steam
• Initiate trading with new friends in Steam
• Buy items, if user has money
• Send a trade offer
• Accept pending trade transactions
• Sell items with a discount in the market[/quote]

Make sure everyone is aware of the problem in your friends list please so no one gets caught in such an issue. As if Twitch chat wasn't already AIDS.
