Bye-Bye 32 Bits?
by Lawrence D'Oliveiro 06 Aug '15

06 Aug '15

The Fedora project <http://phoronix.com/scan.php?page=news_item&px=Fedora-i686-Non-Blocking> has noticed that very few of its users seem to be on 32-bit systems nowadays. This was shown by a kernel bug that went undetected for two months, that prevented 32-bit x86 systems from even booting. Time to relegate 32-bit machines to the junk pile?

New attack on Tor can deanonymize hidden services with surprising accuracy
by Peter Reutemann 03 Aug '15

03 Aug '15

"Computer scientists have devised an attack on the Tor privacy network that in certain cases allows them to deanonymize hidden service websites with 88 percent accuracy. Such hidden services allow people to host websites without end users or anyone else knowing the true IP address of the service. The deanonymization requires the adversary to control the Tor entry point for the computer hosting the hidden service. It also requires the attacker to have previously collected unique network characteristics that can serve as a fingerprint for that particular service. Tor officials say the requirements reduce the effectiveness of the attack. Still, the new research underscores the limits to anonymity on Tor, which journalists, activists, and criminals alike rely on to evade online surveillance and monitoring." -- source: http://arstechnica.com/security/2015/07/new-attack-on-tor-can-deanonymize-h… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
