I remember reading recently that some nasty DDoS code had been released. The article made it seem like the Feds were closing in on someone who may have released it to muddy the waters if others started to use it as well.
Caught part of another article and it said that more sights are getting hit.
Sites taken down by the DDoS attack:
• Twitter
• SoundCloud
• Spotify
• Netflix
• Reddit
• Disqus
• PayPal
• Shopify + more
