More on Hating Agents

2008-02-13 14:54:00 by Dr Anton Chuvakin in Anton Chuvakin Blog -
 
...RAM on each system (sometimes A LOT, sometimes - not so much when such agent crashes, it can take the system down with it (or use up ALL CPU/RAM/disk resources added risk: you run new - possibly vulnerable! - software on all systems (some agents will also allow people to control them remotely for management, thus opening another hole added...

Dell System with Useless Memory

2008-09-20 07:03:21 by Editor in Cheap Hack
 
...RAM. As I discussed in my recent column on when Windows goes all 64-bit , in 32-bit versions of Windows at most 3.1GB to 3.5GB of RAM are usable, probably more like the 3.1 number. You need 64-bit Windows to use all of the memory. Was Costco selling a Win64 system? Nope, the ad says it has "Microsoft Windows Vista Home Premium 32-bit." Beware...

Laptop encryption hacked by accessing RAM

2008-02-21 14:48:04 by Editor in Adventures in Security
 
Many bloggers--including me--have written about the necessity of encrypting laptop information. However, it was only a matter of time before someone found an innovative way around this data protection control

Encryption defeated, still an advocate?

The Article has images
2008-02-22 16:15:15 by Evan Francen in The Breach Blog
...RAM remanence [ sic ] effects to recover cryptographic keys held in memory OK. What does this mean to the non-geek? It means that there are now successful attacks against many encryption implementations, including those most commonly used on mobile devices (laptop, thumb drive, etc.). Here at The Breach Blog I have advocated the use of hard...

Disk encryption not enough?

2008-02-21 17:14:00 by Manu Namboodiri in Data Protection, Management and Leakage
 
...RAM on a locked system There was another article recently in eWeek that talked about FDE not being sufficient protection. I personally think that we need defense against multiple scenarios - not sure if the defense-in-depth term can be used, but seems to fit the best Looking forward to understanding this a bit more

...RAM and extract the encryption passwords kept in clear text. The research concludes that almost all disk encryption products have the same fundamental flaw that enables anyone, without custom-built and expensive resources, to gain access to the system. Rich Mogull has a good blog on how one should think through the ramifications This is...

Q&A: A stick of RAM, a can of air, and wow

2008-03-10 11:22:52 by Editor in Computerworld Security News
 
What's the deal with that "cold book" vulnerability? Why would canned air, adroitly deployed, make data in volatile memory... not so volatile? Computerworld talked to Princeton's Dr. Edward Felten to get to the bottom of that brain-freeze-inducing hack

To sleep, power off or hibernate - cold boot and user behaviour..

...RAM to 0 degree Kelvin!?! Maybe the guy who makes the Terminator movies I must admit the video was cool to watch - frozen chips... And therefore, most of the focus seems to have gone in that direction - thinking that one needs to cool the chips to extract the memory contents. But in reality, one needs only a USB drive with code to peek into...
