Paranoia..Paranoia..Am I on the right track?.. any help please?
So much of what a computer does can never be fully hidden unless one
fully and completely wipes a drive, that I was wondering if my latest methods might be useful. I do not have a real current machine, but still powerful enough to pull this off - my config is: 768MB memory - P4/2400 - ATI Radeon 128MB Video Card - 7200 RPM drives, etc. I find that Virtual PC if one uses nLite to create a custom install of XP runs close to a P3 level for XP. I would say it feels somewhere between the P2 I had at 450mHz and the P3 at 733mHz. Even DirectX works in software mode (as long as it is a program needing DX7 and under) fairly close to a 486 w/32 MB memory. Games are not my need, but Microsoft Baseball does work OK in software mode with nLite setting XP to run at about 60MB of memory needed for internet access, Word 7, newsgroups, media player (if file SVCD size and under). Overall - livable, when using the setup for security. I am using TrueCrypt to create an encrypted container, and then having VPC create a virtual disk within the encrypted container to run XP. VPC is running in the open, but the virtual machine is running from the encrypted disk. I installed TrueCrypt on the virtual machine, and created a container over the network on an open drive to send the info I wish to keep via shared folders - and then shred the virtual machine using a system wiper with a 35-pass routine on the encrpted drive. When I am ready to start again, I bring a clone of the original back into the container. I have looked and looked on the Host machine for any signs of any activity and I can find only a logfile of internet activity, which I have set to auto shred. Am I missing something? Is the Host machine (remember the Host and Guest are the same machine - just made to look different) keeping track of any activities of the Virtual Machine? I cannot see that it is happening, but I would wonder if folks other than myself could see a glaring hole here. thankx, any input welcome |

A delving into the theoretical would be cool ( a sixties phrase - I am 52 ) - much along the lines as to why Hard Drives can hold more magnetic data with same platter size - I receive tech magazines weekly explaining this theory in just such a detail - I am not interested as practical results are more important than theory, in what pays for my home. I would like to explore your answer if I can ask questions not 100% on target as my education is a tech. I can see by your answer you could help fill my mind with answers if I ask correct, and at same time expand my learning if you are not against being a teacher. All people need a teacher to learn. In my mind, my basic question was not answered. Using this technique - am I safer than not? thanx.. hope me being 52 not against you teaching - no matter your age. bye now. I have to close every message a very single way and sometimes new folks find it offensive - it is just a way to let folks know who I hold dear besides my wife, so I am going to end this way, and never an Arab, nor ever a Jew - ever said - In Jesus I Bless You Today and Hope God Watches You and Yours, In Jesus Bill I hope you are not offended - you have a brilliant mind. bye |

What about some malware breaking out of your VM and modifying the host OS? At least for Virtual PC this shouldn't be quite hard, as it doesn't trap various relevant CPU instructions like LGDT. |

HD's usually last myself about 3 times the life of a computer OS. The last drive I purchased was a 300GB IDE Seagate Ultra ATA 133. The next computer I am looking at has no support for IDE - but rather SATA only. I figure a new computer every three years saving $1.00 to $1.50 per day for it - not bad. $1200 - $1800 to spend. I forgot to add the other point - which I have been doing since learning of Ghost. The entire partition with the OS of the Host is Ghosted every single day. With two HD's - I use the 40GB that came with the computer as the main OS drive, and once weekly run a DOS wipe of the drive - Jetico's PDwipe utility under DOS which is freeware from BCwipe, just using a seven wipe DoD pass - then Ghost the drive back to life. Been doing that for years until I learned of encryption in the 2000 days. I burn DVD's holding encrypted data as backup - BestCrypt which while trialware allows one to continue reading data - until TrueCrypt which is freeware. But if a computer cannot handle three years of being on 24 hours per day, seven days per week - then I chose a wrong computer. DELL workstations found in the business section of the website, have never let me down yet since the 486 days. A few bucks more - but industrial strength. I just never turn them off - and they last and last. They are not gaming machines - but they can handle games all but the highest end new ones, and they last and last - until I decide a new one in order. Best let you go. With a DELL workstation, lasting is not an issue, as they carry a one-year standard warranty for free with purchase and for $60 more - a three year complete warranty. thanx, Bill |

Then you have a serious problem. The computer OS should last at least as long as the HD, the latter usually being the limited. > I forgot to add the other point - which I have been doing since learning > of Ghost.

Wow, what a big waste of time. |

I guess it seems to be overkill - but not just to me. You talk about killing a drive - as if 10 cents per day was serious money. 3 years at 10 cents per day is $100 give or take a bit - and a dime a day for feeling safe - Car insurance for full coverage per month on a new car - even with an excellent driving record, costs me that amount every two months - give or take. We are talking about a dime per day to feel safe. You misunderstood because of the way I typed the information that somehow a HD was dying soon. HD's die soon for myself as I like video. A Tv- card captures at a set rate, but uncompressed AVI the best. Uncompressed video takes abot 2GB per minute at 720x480 size - a DVD. The next gen of video will be at least 1280x720, but my monitor is 1920x1080i - The next HD will need to be in the TB range, which Seagate is now working on in order to keep up with video. So in my instance - I expect a HD to last less than an OS because video is always pressing speed and capacity. When the Bluetooth DVD arrive, I will have a way to playback video, but not capture video at High-Def rates until I obtain a 1TB drive, which will just be a stopgap until larger TB drives come out. I have never once put anything illegal on my harddrive, but maybe my wife might not like to see the 38 year-old neighbor, me being 52, video footage when she laid in the yard in her bikini. Other issues as well. As for time - you seem to think it takes a lot of time. If you destroy the header of a HD - fat table, etc. through a wipe, and then use a shred utility every time you destroy a file, the drive cannot be reconstructed. It takes about 2 minutes to destroy the header - and about 7 minutes to Ghost the drive back up. Say 15 minutes per day - to feel totally safe. 15 minutes is nothing compared to almost 30 years of marriage. Some folks wear rubbers and others don't, but the folks who think a minute or so might interupt the joy - should not be surprised they become pregnant. And even then - sometimes it breaks. That is why I was asking about if maybe I am missing a point. thanx now - your time spent in answering was appreciated ver much. cya |

I avoid wiping my hard disk by doing a whole disk encryption with PGP and after that I just put back the clean OS again, kept it mirrored on an external hard disk. The theory is that PGP whole disk encryption could have attempts of brute force attack but an attacker would need to recover the whole disk before trying, and it is unlikely anyone would ever succeed in recovering every single byte, recovering just a part would not be of any use. By wiping the whole hard disk it is possible that some small bytes of data are not deleted properly, but with an AES256 whole disk encrypted system all the data an attacker could see if he managed to recover somethign is a piece of garbage in AES256. It still takes time to encrypt the whole hard disk but as it only writes it once I believe I extend its life. Of course it is possible that some snake oil software does not encrypt the whole hard disk as advertised, I stick to PGP wich I have tested myself by looking into the disk with Winhex. Drivecrypt does the same job I just haven't tried it. |

And as for as I can tell - a Hard Drive has roughly eight underlying positions - that can be accessed. A drive only erases the first level of a file. It places a Zero in the spot. That is why HD manufactures have programs to Zero Out a Drive. Meaning to place zeros in every available spot. If there eight spots per place and every spot is now a zero - then super erase not needed. But Windows is not a low-level function. The freeware program from Jetico, included with their shareware wipe - really wipes a HD. Anything else than pure wipe to zero - something is there. You can zero your drive, install your OS - then Ghost your system to a CD-ROM which is always clean - and then re-install daily after destroying the header data using the Jetico prog - with Ghost who took a snapshot of system clean, and remembering computers go eight level deep - Only God would know about your system before. It takes about 15 minutes daily - and if Ghost set to include all your progs - nothing more. To use it it you need two drives, or set up one drive to have two partitions. If you would like to try, and you only have one partition now - you would lose data. But then you would feel safe. I think. Best let you go. My method does not care how many people know it - it is not a secret - it just works. cya |
