NTP's days are numbered for consumer devices
An accurate clock is required to negotiate SSL/TLS, so clock sync is important for internet-of-things usage. but:
Unfortunately for us, the traditional and most widespread method for clock synchronisation (NTP) has been caught up in a DDoS issue which has recently caused some ISPs to start blocking all NTP communication. [....] Because the DDoS attacks are so widespread, and the lack of obvious commercial pressure to fix the issue, it’s possible that the days of using NTP as a mechanism for setting clocks may well be numbered. Luckily for us there is a small but growing project that replaces it.

tlsdate was started by Jacob Appelbaum of the Tor project in 2012, making use of the SSL handshake in order to extract time from a remote server, and its usage is on the rise. [....] Since we started encountering these problems, we’ve incorporated tlsdate into an over-the-air update, and have successfully started using this in situations where NTP is blocked.

Microsoft Security Essentials reporting false positives on the Bitcoin blockchain
Earlier today, a virus signature from the virus "DOS/STONED" was uploaded into the Bitcoin blockchain, which allows small snippets of text to accompany user transactions with bitcoin.  Since this is only the virus signature and not the virus itself, there apparently is no danger to users in any way.  However, MSE recognizes the signature for the virus and continuously reports it as a threat, and every time it deletes the file, the bitcoin client will simply re-download the missing blockchain.


What a heinous prank! Hilarity ensues (via gwire)
