How to take down a botnet

Very interesting explanation of how a botnet “sinkhole” is used to subvert a network of compromised computers.

Infected machines typically receive commands from other infected machines — this makes it more difficult to “decapitate” the network by eliminating a single command-and-control server. The peer-to-peer network can also change quickly in response to threats; each node can propagate a list of new peers if there’s an intrusion. But it’s exactly this capability that enables the “sinkhole” technique. If researchers can crack the communications protocol used among the peers, they can create “poison” data that will propagate through the whole botnet. The data forces all peers to connect to a single machine. That machine, of course, belongs to the white hats, who now control the botnet.

UK court breaks the Internet

From The Consumerist:

File-sharing in the United Kingdom just got a little bit more difficult, as the nation’s High Court has ordered the country’s largest internet providers to completely block access to BitTorrent site The Pirate Bay.

What makes this truly idiotic is that now that the entire Pirate Bay can be stored on a flash drive, there’s an infinite number of mirrors that can appear elsewhere. It’s effectively unblockable.

Private awkward moments

Step 1: a friend of mine on Facebook, whom I’ve known since she was 14 or so and is now in college, posts to say that she’s holding a marathon watching all eight Harry Potter movies.

Step 2: I see this in my RSS feed.

Step 3: I feel like I’ve done something wrong.
