Newegg was hacked.
Recieved this email from Newegg:
Yesterday, we learned one of our servers had been injected with malware which may have allowed some of your information to be acquired or accessed by a third party. The malware was quite sophisticated and we are conducting extensive research to determine exactly what information may have been acquired or accessed and how many customers may have been impacted. We will keep you up to date with our progress and work to ensure this doesn't happen again. The malware is no longer on our site and we will be doing our best to bring the culprits to justice.
We have not yet determined which customer accounts may have been affected, but out of an abundance of caution we are alerting those accounts at risk as soon as possible so that they can keep an eye on their accounts for any suspicious activity. We hope by alerting you quickly to help prevent any misuse of information that may have been acquired or accessed.
By Friday, we will publish an FAQ that will answer common questions we get; we will send you a link as soon as it goes live. We will also publish the link on our social media platforms. We want to make sure you are completely informed.
We are very sorry circumstances have warranted this message. We are working diligently to address this issue and will provide additional information to you shortly.
Sincerely, Danny Lee, CEO Newegg
If you've used Newegg to buy stuff get new cards you've used to buy stuff on there changed and if you used shared passwords, which you never should, change those too.
According to outside articles it was a skimming attack. Its believed that people who've purchased from them from August on, the US website and possibly CA website, could be affected.
