"What we want to show is there is no 100-percent security," he told Ars
moments after unleashing code that remotely caused a high-end Asus laptop
to open a calculator program. "So even if you have a fully updated system,
you can still get your system compromised. "

The overall message? Security is an arms race being fought between
attackers out to plant the kinds of sophisticated espionage malware used to
spy on Google and dozens of other companies and the software companies
trying to prevent such exploits. While defenses such as sandboxing, data
execution (DEP), and address space layout randomization (ASLR)
significantly raise the bar for such attacks, hackers inevitably find ways
to work around them."

I'd like to see specific details of this. Something was amiss if remote
code was allowed to execute with enough rights to call out to a program on
the local machine.

This reaks of a specifically targetted attack vector.

The recovery plan is really a cut/paste job from various sources
paraphrased with you as the sole author. Aside from that, it has
limitations in usage. It's primarily for hardware failure/theft data
recovery. It's still, despite what you want to think, unsuitable for
disinfecting a machine in most cases. It's overkill, excessive and a
shotgun approach for what could turn out being a relatively minor problem.

It's staggering to me that you freely declare you are *not* an expert in
such matters yet in practically the same post, infer that you are with
these plans of yours.

On a more serious note, You preach that such and such av/am app is better
than such and such other app, but you provide NOTHING substantial to
support the claims. You've mentioned you test the products yourself and
some of your comments are no doubt based on the results. However, when
asked about your testing methodology you won't divuldge it or share
samples via non public secure means with people (like me. lol). Who,
incidentally, actually are experts in malware amongst other subtopics
related to IT and IT security. You tried to use the absurd excuse the
samples you have are not for redistribution, but uhh, that is infact the
primary function of the programs--Assuming they are actually malicious in
nature. We have no way of knowing as you aren't willing to allow others to
safely examine them.

It's highly unlikely in reality that you have a source for malware that
the rest of us have no way of gaining the same family (maybe not identical
bins due to possible server side polymorphism) as you claim to have. That
couldn't be further from the truth. Researchers do share samples via
secure channels. You have no reason to need to protect us from possible
harm due to the samples you have, We aren't children here.

Several of us have either authored our own tools or supported those who
did directly in technical roles. Some have done both and still continue to
do so today.

It's my opinion that you likely know as much about malware executables or
the structure of a win32/64 PE about as well as you understand that system
images are not really intended for recovering from malware. They can
certainly be used for it, and in rare cases, behind a hardware firewall
while it's being blown back on (restored), but to tout them as a cure for
a virus or browser hijacker just reaks of amateur.

Having a recovery plan is good, but prevention of theft in the first place is paramount.

He contests that you shouldn't keep anything important on a computer. That's all fine and
dandy, but unrealistic. People take risks in all sphere's. The sensible one's quantify
them, take steps to minimize them, and mitigate against consequence.

I agree. To slightly expand on prevention of theft, this is where crypto
comes into heavy play. In the event an image drive is misplaced or taken
without your permission, so long as a good crypto policy is in place on
the contents; it does the thief no good aside from reformatting and
using the drive for other data. The idea of course is that your data
should be destroyed rather than fall into the wrong hands. Unreadable
for most purposes is considered destroyed. Truecrypt is a nice app these
days if used properly, the enterprise/forensic editions of various apps
like passware can't breach them in any realistic amount of time. Using
multiple keys with keyfiles pretty much screws most individuals from
gaining unauthorized access. As we've seen in a real life court case
recently, the federal government doesn't have the ability to break any
crypto as we see on law and order and ncis. Short of a flaw in the
algorithms themselves or the implementations or improper key length, etc
etc, they aren't getting in. If uncle sam can't read your things, it's a
good bet your typical punkass thiefing little rat bastard won't be able
to either.

The most obvious drawback to cyphering image files tho is that should
the file become damaged, or you forget the keyphrase and/or lose the
keyfiles (You should use both, imo for the best possible opportunity to
lose your shit for ever. hehee) you run a good chance of losing all of
the contents, vs some file damage had it not been encrypted beforehand.

It's a tradeoff. In my case, some of the stuff is important enough to my
freedom that I'd rather lose the data than let anybody who shouldn't
read it do so.

That's extremely unrealistic. Computers are intended for people to do
things. In order to be productive and get things accomplished, they tend
to retain large amounts of information. As opposed to reloading EVERY
single file/section of code/html/xml, whatever each and every single
time you open project A, let alone project B, C, etc.

As you said, risk exists. There is no escaping it, there is however the
possibility of mitigating damages and losses.

Well, in the upgrading aspect, I'm not one for supporting unnecessary
upgrades. Just because something is newer doesn't necessarily mean it'll
serve me any better than what I already have going. It just depends on
the needs of the equipment for the task(s).

I've seen alot of cnc systems running custom software on very customized
hardware, in some cases, in shop built electronics on a pci card inside
the controller machine. You really don't want to start ****ing around on
those machines and upgrading software or hardware if you don't know for
sure what everything is doing. Especially if the cnc machine is
responsible for providing racing class engine parts. That's one sure way
to get yourself in a real mess and piss off a client.

Such is exactly what a world wide major corporation I work for does to
restore employees computers when issues arise. They certainly don't
spend (waste) the time to dig around and find and remove malware or any
other issues. Now you and yours fantasies about major Intranets being

attempt for you to try and find some high ground. It just doesn't fly

First of all, an image could disinfect a machine if it's doing the
restore at the sector level; it's just not intended solely for that
practice. Second, your time estimates are absolutely ****ing insane. You
*must* be using recent hardware to get those speeds. I certainly don't
have a machine here able to restore 50gigs from usb 2 in
15minutes...That's moving pretty damn good dude... heh. Decompressing
the image in memory, restoring to the system.. in 15 minutes? What are
you running?

Using Macrium reflect free edition from windows xp on this machine took
over 2 hours to backup 52.7 gigs onto a WD 1tb usb2 external. I couldn't
boot the recovery disc and use my mouse, Seems the vista PE environment
it's based on doesn't like ps/2 mouse? lol... And if you press the tab
key one too many times, you have no way to continue using the app on the
PE disc. You get stuck selecting/unselecting source drive(s). Sadly, it
selected them all by default, including my destination usb drive; so...
without a usb mouse (lol), PE doesn't work so well. IE: I couldn't get
back to enter the location once I hit the tab key too many times. And
thanks to auto selecting ALL drives, I couldnt proceed with the backup
without tabbing over to deselect my destination drive. What a ****ing
chore. lol.

You really don't test things good before you recommend them. It's a
usable app, but .. kind of a pain if you run it on older stuff.

I don't think of reverse engineering software as a waste of time. I've
learned alot along the way and made some good money at the same time.
Your milage may vary. You remind me of the car mechanic who replaces
parts until it runs again. Whereas a real mechanic would replace the bad
