Many of us have torrents and like Us crime dramas without ads.:) (probably)

dumbers hardly fits into that category

Just dont forget to tip your deity. Check your local childrens hospital - the parents of that 3 year old with bone cancer that screams all day (even after meds), obviously didnt pay up enough in the omnipotent shakedown.

there are military or high security environments still using RSA?

Cold Reboot Attacks on Disk Encryption 398

Posted by CmdrTaco on Thursday February 21, 2008 @12:40PM from the wont-someone-please-think-of-the-bits dept.

jcrouthamel writes "Contrary to popular assumption, DRAMs used in most modern computers retain their contents for seconds to minutes after power is lost, even at operating temperatures and even if removed from a motherboard. Although DRAMs become less reliable when they are not refreshed, they are not immediately erased, and their contents persist sufficiently for malicious (or forensic) acquisition of usable full-system memory images. We show that this phenomenon limits the ability of an operating system to protect cryptographic key material from an attacker with physical access. We use cold reboots to mount attacks on popular disk encryption systems — BitLocker, FileVault, dm-crypt, and TrueCrypt — using no special devices or materials. We experimentally characterize the extent and predictability of memory remanence and report that remanence times can be increased dramatically with simple techniques. We offer new algorithms for finding cryptographic keys in memory images and for correcting errors caused by bit decay. Though we discuss several strategies for partially mitigating these risks, we know of no simple remedy that would eliminate them."

Largest Hacking Scam in Canadian History 211

Posted by CmdrTaco on Thursday February 21, 2008 @10:27AM from the stole-all-the-maple-syrup dept.

vieux schnock writes "Police raided several homes across Quebec on Wednesday and arrested 16 people in their investigation, which they say uncovered the largest hacking scam in Canadian history. (...) The hackers collaborated online to attack and take control of as many as one million computers around the world that were not equipped with anti-virus software or firewalls."
