Google Is Leaving China (10)
on
The Next Web (1333) permalink
Google’s talks with China over censorship have stalled and it now appears that Google will leave the Chinese market entirely.After Friday’s announcement that China would not cave on censorship regulations for Google, which came after Google announced that they would not censor their searches, this showdown seemed imminent. With neither party prepared to cave, the Financial Times is reporting that Google “is 99.9% certain” that they will quit the Chinese market.Looks like Baidu’s share price ...Shared by Ankush (61) giorgiojannis (44) Jardenberg (388) Jonathan (30) marleyuk (390) Nicke (175) Nikke (20) Ren (57) RK (268) StephenRossScott (57)- Nikke said: Vet inte jag. Tycker fortfarande att det är det mest rakryggade av Google, men samtidigt behövs kritiska röster i Kina...

1024-bit RSA encryption cracked by carefully starving CPU of electricity (17)
on
Engadget (4892) permalink
Since 1977, RSA public-key encryption has protected privacy and verified authenticity when using computers, gadgets and web browsers around the globe, with only the most brutish of brute force efforts (and 1,500 years of processing time) felling its 768-bit variety earlier this year. Now, three eggheads (or Wolverines, as it were) at the University of Michigan claim they can break it simply by tweaking a device's power supply. By fluctuating the voltage to the CPU ...Shared by anton (15) Bill (88) Cadu (14) Chrigi (103) Chris Escalante (7) DennisLaumen (102) Gareth (24) GeneN (37) Godie (23) Gregor (42) and seven more »Comment View comments -

- Metaphox said: OMFG this is brilliant
- Steven said: Uh, crazy!
- t said: If you already have physical access to my machine, I've already been pwn3d.
- Aaron said: Wow. Very clever.
- David said: Sharing because it's an example of something I've been ranting about related to DRM - once again, no key or lock exists that humans won't find a way to pick, and they're exceedingly clever about it.
- Monkey said: Wow... Just wow... This is truly impressive.
- chitchu said: This is freaking awesome. And scary at the sametime.
- Will said: Ok, so the theory goes something like this: Someone with, possibly, physical access to a server with the private key, and is able to tamper with the power supply to cause the server to "flip single bits of the private key". With enough of these power fluctuation, a person can decipher the private key.Here's how countries can win all future cyber wars using the method. All they have to do is to create PSU's that's been modified to cause these power fluctuations to aid the attacker in deciphering the private key. Once the private key's been made clear text, all the target's OpenSSH connections will be opened for other exploits!Damn. I wonder if it is even possible to monitor these small power fluctuations to guard against this kind of attack?

- ant said: This is ingenious; I wonder how they discovered that vulnerability. A truly old-school hack reminiscent of the old blue/red/brown box hacks.

- alt said: ... "or ending human life as we know it." Potrei dire "calzante" :/
- Eduo said: Lo realmente increíble es que la técnica es, fácilmente, lo más parecido a una versión electrónica de la típica ganzúa que va meneando hasta ir enganchando cada uno de los cilindros de una cerradura (o la típica caja fuerte y el estetoscopio).Genial.
- Ira said: Holy crap, those hackers are mad. At least it's not something you can easily do (you need physical access to the machine - VERY physical and intimate access to the motherboard and a long list of other parameters working for you, I think simply reading the memory of the server would be easier :)

Security Expert: Flash Is the Root of Browser Insecurity (Oh, and IE8 Isn't So Bad!) [Security] (17)

Gizmodo (5715) permalink
You're probably relatively confident in your various machines' integrity against hackers. Repeat Pwn2Own hacking competition victor Charlie Miller would like you to know that you're wrong—especially if you have Flash.In an interview with OneITSecurity, Miller picks off questions about hacking and security with just enough ease and nonchalance to make me queasy. Like, you know how Mac OS exploits are supposed to be tougher to root out than Windows exploits? Not quite! And they're both ...Shared by Aaron (193) Alex (530) Allan (6) aNTwNHs (205) CPUKP (7) Daniel (364) Dwight (16) Gordon (21) I (162) Jeff (the メガマクダジ of FF) (268) and seven more »- Alex said: "So the guy who consistently prevails Pwn2Own, a competition where hackers demonstrate exploits for sport, says that Flash, which is installed on about 98% of computers on the internet, unifies all browsers in insecurity, and that IE8, an Internet Explorer browser, in case you're having trouble unfolding that acronym, now ranks among the safest in its category."
