But all of the attacks, separately, are plausible, no? Even the crazy ultrasonic networking between infected laptops -- I'm a little surprised they didn't include passing QR codes by line-of-sight with the built-in webcam, but maybe that's in the next version. Why shouldn't we be genuinely concerned about the upgradeable software resident in the bare metal of a server or locked-down workstation? Do our drivers provide sufficient protection against flaws in the proprietary subsystems they talk to? Or are those subsystems generally considered immune to attack? If I wanted to exercise some paranoia, are there standard tools for discovering and checksumming the firmware on a system, to detect if it is tampered with over time?

The Haiku OS kernel debugger can print a qr code on the screen so someone can look up exactly what the issue was when the box crashed. So they say . It sounds very interesting and I am amazed that Android or iOS do not have this yet. As for your question about checksumming firmware, you could take a look at flashrom http://flashrom.org/Flashrom . This super useful tool can dump the roms from a number of devices including system bios, network cards etc. >From there you could checksum the output and track it. Back to Ike's Gem of a story, the more I think about it the more this sounds real. I would not doubt that a 3GO has done this sort of hack , and why not who would look there. I am thinking we , NYCBUG, should start a company that makes LED lights that screw into normal sockets that contain a small arm or mips system . Spooks would love this crap. We'd make a fortune. :) To Ed's point its not the java language that's bad; its the people who what to say the solution for your business problem is another language . Sure this can be a real issue, say your companies products are all coded in some obscure dialect of pascal, your head programer quits, and no one is capable of handing his work. This would be a good reason to think about recoding it in another language that your staff has better skills with. However, your company is not making enough money , you should use java/.net/cobol/php/ruby/BF/python/voodu/blackmagic is a bad idea. Its all the same to me its the means to make the product its not the product. Unless you are Sun, Oracle or IBM. -- Mark Saad | mark.saad at ymail.com -------------- next part -------------- An HTML attachment was scrubbed...

That is what I was wondering. I understand the case of a motherboard BIOS, if something could re-write the firmware. I think that is very possible because now many vendor tools re-write the firmware without requiring you to boot from a CD. This is one thing that makes the story questionable to me. In the case of a USB stick, it would seem pretty easy to purchase two usb sticks, stick one into your "corrupted" network and then compare the firmware on the two units to see if an actual change happened. In the BIOS case, couldn't one use VMware? After all VMWare emulates a BIOS start an image see if the image changes in a substantial way. The mame community somehow manages to extract (BIOS) information from hundreds of arcade machines....

This meeting will cover regex basics, and based on audience participation, it may go well beyond." So let me pose this question to Moe in advance: I principally write software in Perl, so I am very familiar with regular expressions themselves. Very occasionally, however, I have written command-line programs which pipe a string to 'sed' for pattern matching, and I've even used (or maintained) 'system' commands within Perl programs that involve piping to 'sed' or 'awk' for pattern matching. Do you have any guidelines or rules of thumb for when you would use one language's regexes versus another's? (There was one point several years ago when I benchmarked a use of Perl regexes versus sed regexes, but I don't think the results were conclusive.) Thank you very much.

In particular: grep -P. I tried this on three different machines: an older Mac OSX laptop, an older Debian Linux server (Linode), and a more up-to-date Debian Linux server. I maintain (so to speak) the first two boxes; professional sysadmins maintain the latter. On the two machines I maintain, I use whatever 'grep' came with the machine. And on these two machines, the '-P' option, though documented in the manpages, did not work, as those greps had not been compiled with that option. Darwin: grep (GNU grep) 2.5.1 $ echo "abacus babble b a ba ab cabriolet" | grep -P '(?=a)b' grep: The -P option is not supported Linux (mine): $ grep -V GNU grep 2.5.3 $ echo "abacus babble b a ba ab cabriolet" | grep -P '(?=a)b' grep: Support for the -P option is not compiled into this --disable-perl-regexp binary Linux (not mine): $ grep -V GNU grep 2.6.3 $ echo "abacus babble b a ba ab cabriolet xenacb" | grep -P --color '(?<=b)a' abacus babble b a ba ab cabriolet xenacb So, your results with 'grep -P' will depend on how the version of grep you're using was compiled. YMMV. Thank you very much.

It seems like any automation between the volume decryption and getting s*$+ done would leave you vulnerable in some way. It is not like a unique code can be generated on the output of one step that can be part of the input of the next step. What about something like the Yubi key? It means you have to have a USB port (which you do not seem to be opposed to) and you don't have to type your passphrase(s) over and over. See http://geekyschmidt.com/2010/12/27/yubikey-and-my-desire-to-beat-the-feds-to-hspd12-compliance for a post about it. I've not used it with OpenBSD, but I've used OTP at a couple of sites with a warm sense of safety (but that might of just been the heat generated by the NSA using my CPU to decrypt hashes). Ra?l p.s.

YubiKey is brilliant because generating one-time keys can be used as a replacement for passwords OR as an inexpensive way to set up two-factor authentication.

But if the hardware is there for serious accuracy, and openntpd isn't, then explain why they make sense as a duo.

Okan
But does it support random(4) . Seriously has anyone on the list setup this combo in open or another BSD ?

I don't understand what you're asking.... read ntpd.conf, noteable of the below configuration: sensor device [correction microseconds] [weight weight-value] [refid string] [stratum stratum-value] What openntpd might be missing are the features that like a tiny tiny fraction of people need/use. The ntp source might be this great GPS device, but now one has an ntpd server servicing requests from some random network...go hog wild on the gps side, but one can lose how much of it once it "on the network"...?

They dont need any special drivers. Just write a small program in whatever. I wrote one in VB a long time ago and the device output from the device was easily parsable strings. Maybe you'd have similar luck. GPS hasnt changed I dont think since then. -------------- next part -------------- An HTML attachment was scrubbed...
