The Hunt For LulzSec's Missing Sixth Member
DavidGilbert99 writes "LulzSec's star burnt brightly in the short period it was active, but things quickly turned sour when its core members began getting arrested. Last week three of the six core members were sentenced in the UK, but this only served to highlight the fact that one member of the group, known as Avunit, has been able to remain unidentified despite the FBI having turned the group's leader Sabu into an informant. Who is Avunit? And does he hold the purse strings of the group's Bitcoin wallet which could have up to $180,000 in it?"
As usual, be warned of the horrendous autoplaying video ads surrounding good content at the primary link.
If IBTimes wants to piss people off with autoplay videos, why link to them?
Here's El Reg's version of the same story:

"I've got more toys than Teruhisa Kitahara."
You've obviously not used Bitcoin a lot.
You can have as many wallets as you like and a wallet can generate as many "addresses" as you want to receive money on. Outsiders have no idea that two distinct Bitcoin destinations aren't in fact the same wallet.
Additionally, only the network as a whole really knows where the transactions are coming from, an individual Bitcoin user doesn't (otherwise it would be pointless!). It's peer-to-peer so somewhere, some peer knows what IP generated that transaction. But without having control of a vast proportion of the whole network, down to the IP level, there's no way to reliably trace anything back to a "real" IP, person, wallet.
Transactions are logged. But with wallet addresses. And you can tell what wallet addresses should have how much money in each. But you can't tell which wallet addresses are the same address, nor where they come from, nor who owns them. A transaction will just appear in the blockchain and come from several thousand peers almost simultaneously who share the information across the network and even the first one on the list isn't necessarily the client who first saw the transaction.
And those clients are private peer-to-peer clients. If my client was the first to see your transaction, you'd have to raid ME to get the IP information from my systems - and what are the chances of a random Bitcoin user having full network traces of all the actions on their network, going back to the transaction you're interested in, by the time you find them?
Transactions are basically sent to random people in the swarm. They talk to more random people and eventually the network all sees the transaction. Finding out which Bitcoin address first saw the transaction is nigh-on impossible even with complete knowledge. Raiding them and finding information on their systems that links back that transaction to an originating IP is incredibly unlikely even if you could do that. And if they used Tor or a proxy to initiate the transaction? You're stuffed.
Even collection of funds? They can publish any number of Bitcoin wallet addresses that secretly correspond to a single wallet and anyone who sends them money will NEVER KNOW where it's going. The transaction goes into the swarm and after a while, all clients agreed that wallet address X has amount Y in it. The total wallet, though, might have several million addresses associated with it and even the last client on the route to informing that wallet of a received transaction won't ever know that it's talking to the wallet holder.
No matter what you think of it as a currency, Bitcoin is a fabulously-designed anonymous transaction protocol. About the only threat is one entity holding 50% of the hashing power, but that just gives them the power to control the block chain, not identify users.
