Quantum Cryptography Cracked

December 30th, 2009 admin

Impressive: This presentation will show the first experimental implementation of an eavesdropper for quantum cryptosystem. Although quantum cryptography has been proven unconditionally secure, by exploiting physical imperfections (detector vulnerability) we have successfully built an intercept-resend attack and demonstrated eavesdropping under realistic conditions on an installed quantum key distribution line. The actual eavesdropping hardware we have built will be shown during…

FIPS 140-2 Level 2 Certified USB Memory Stick Cracked
Kind of a dumb mistake: The USB drives in question encrypt the stored data via the practically uncrackable AES 256-bit hardware encryption system. Therefore, the main point of attack for accessing the plain text data stored on the drive is the password entry mechanism. When analysing the relevant Windows program, the SySS security experts found a...

Research result #1: “A Generalized Fission-Fusion Model for the Frequency of Severe Terrorist Attacks,” by Aaron Clauset and Frederik W. Wiegel. Plot the number of people killed in terrorists attacks around the world since 1968 against the frequency with which such attacks occur and you’ll get a power law distribution, that’s a fancy...

Hack of Google, Adobe Conducted Through Zero-Day IE Flaw
Editor’s note: This story has been updated with a link to a Microsoft advisory about the new vulnerability as well as a Microsoft blog post discussing ways for users to reduce their risk of attack. The recent hack attack on Google, Adobe and other companies occurred through exploitation of a zero-day vulnerability that affects many versions... 
Hack of Adobe Conducted Via Zero-Day IE Flaw
The recent hack attack on Adobe occurred through exploitation of a zero-day vulnerability that affects all versions of Internet Explorer, according to a security researcher with a leading anti-virus firm. Microsoft learned about the vulnerability only Wednesday evening and is planning to release an announcement about the vulnerability later today,...

Attribution Using 20 Characteristics
My post Attribution Is Not Just Malware Analysis raised some questions that I will try to address here. I’d like to cite Mike Cloppert as inspiration for some of this post. Attribution means identifying the threat, meaning the party perpetrating the attack. Attribution is not just malware analysis. There are multiple factors that can be... 
Post-Underwear-Bomber Airport Security
In the headlong rush to “fix” security after the Underwear Bomber’s unsuccessful Christmas Day attack, there’s far too little discussion about what worked and what didn’t, and what will and will not make us safer in the future. The security checkpoints worked. Because we screen for obvious bombs, Umar Farouk Abdulmutallab...

Microsoft is releasing an out-of-band update for their IE vulnerability. Internet Explorer 6 is affected and is being actively exploited in the wild. The patch will be released on the 21st, today, see Microsoft’s Security Bulletin for additional details. Updated to add : Microsoft Security Bulletin MS10-002 . What version of Internet Explorer... 
F-Secure’s Exploit Shield blocks the "Aurora" exploit
Microsoft recently announced a new vulnerability in certain versions of its Internet Explorer web browser. If exploited, the vulnerability (CVE 2010-0249) can allow remote code execution. Announcement of this vulnerability follows on the heels of last week’s targeted zero-day attacks against a number of companies. Since we are talking about... 
Vatican Admits Perfect Security is Both Impossible and Undesirable
This is refreshing: Father Lombardi said it was not realistic to think the Vatican could ensure 100% security for the Pope and that security guards appeared to have acted as quickly as possible. It seems that they intervened at the earliest possible moment in a situation in which zero risk cannot be achieved,” he told the Associated Press news...
