The NSA Worked To 'Track Down' Bitcoin Users, Snowden Documents Reveal (theintercept.com)

An anonymous reader shares a report: Classified documents provided by the whistleblower Edward Snowden show the National Security Agency worked urgently to target Bitcoin users around the world -- and wielded at least one mysterious source of information to "help track down senders and receivers of Bitcoins," according to a top-secret passage in an internal NSA report dating to March 2013. The data source appears to have leveraged NSA's ability to harvest and analyze raw, global internet traffic while also exploiting an unnamed software program that purported to offer anonymity to users, according to other documents.

Although the agency was interested in surveilling some competing cryptocurrencies, "Bitcoin is #1 priority," a March 15, 2013 internal NSA report stated. The documents indicate that "tracking down" Bitcoin users went well beyond closely examining Bitcoin's public transaction ledger, known as the Blockchain, where users are typically referred to through anonymous identifiers; the tracking may also have involved gathering intimate details of these users' computers. The NSA collected some Bitcoin users' password information, internet activity, and a type of unique device identification number known as a MAC address, a March 29, 2013 NSA memo suggested. In the same document, analysts also discussed tracking internet users' internet addresses, network ports, and timestamps to identify "BITCOIN Targets."

      No that is you. It is just that crypto currencies are a buzz word so every article (good or bad) makes it to the front page (so to speak.) If this article seems bad to you then just take note that when crytpo currencies fall to page 3 their value will drop due to a significant amount of their value being derived from people buying them in a bigger fool scenario and every article that gets published only helps the buzz even if negative. It has to be extremely damming to actually have a significant negative effect.

      For someone wanting to receive money via Bitcoin, it's easy to create an anonymous account, get Bitcoins deposited to that account. The hard part is getting the value converted into real money. That requires a broker. Then it becomes identifiable as to where the money came from. Usually they will be online. You would need a real-world currency cash transfer to be anonymous. Some convenience stores have ATM machines to do this.
