  1. Re:Greylisting on Spam Filtering For Small/Medium Business? · · Score: 1
    Greylisting alone proved to be great... until Srizbi started to generate sizable percent of spam (spambot very widely deployed, and that can handle greylisting rejects and retry).

    Considering that 80+% of all spam is generated by botnets mostly in desktop PCs, not servers, using a blacklist that targets specifically personal pcs (home dsl, dynamic connections, etc, whatever NOT meant to be a mail server) like i.e. Spamhaus's pbl or zen (adds known/real servers used to send spam, closes the other hole in the graylist), should take away a big percent of spam, even without having to receive the message itself. But is good to take this with care, not every server follows standards so greylisting could stop real servers (you can whitelist the ones you really want here), and a blacklist could stop something you want too (mail server logs could be useful to check what is being stopped).

    There are far more things you can do to reduce spam, but the bulk could be handled with this 2 simple measures..

  2. Free energy for all! Ill explain how... on Gmail As Open-Relay Spam Server · · Score: -1, Offtopic

  3. How it looks like? on What a Botnet Looks Like · · Score: 2, Funny

    There are fields, Neo. Endless fields where bot beings are no longer born. Are grown. For the longest time I wouldn't believe it and then I saw the fields with my own eyes...

  4. The Bank... i mean, Data Center Job on Peter Gabriel's Web Server Stolen · · Score: 0, Troll

    Maybe in that Data Center some servers had stored images used in the extortion of the British Crown or corrupt cops, and the thieves were in fact hired by some english agency to take those servers out... and Peter Gabriel ones were unfortunately close to those ones. Wonder if jasonstatham.com had the servers in the same data center.

  5. Alternate Cast on MacGyver Film In the Works? · · Score: 5, Funny

    Rename the movie to MacGyver Brothers, and performed by Jamie Hyneman and Adam Savage. Would love to see the extra-dvd content where they show how and where the movie they just acted was wrong.

  7. Where they found it? on First Superheavy Element Found In Nature · · Score: 1

    Maybe is a missing piece of information in the original article. Chernobyl? Bikini Island? Geneva? Roswell? Maybe could be "natural" in those places and not in the rest of the world/nature.

  8. Avoid bloat on Average Web Page Size Triples Since 2003 · · Score: 2, Informative

    NoScript is your friend. Avoid a lot of bloat (flash/javascript ads?), and adds some security

  9. Problem vs solutions on Malware Modification Contest Has Antivirus Vendors Upset · · Score: 1

    Malware=problem, antivirus/security products are part of the solution. But what if you hit a problem that have no (practical) solution? What if next generation of malware using that technique make very hard/impossible to deal with them? Once you reach the point that you cant tell when something is even potentially malware, all are in trouble.

    Probably would be more clear if they were investigating with genetics/biological malware instead of computer one.

  10. Re:Is Mathematics Discovered Or Invented? on Is Mathematics Discovered Or Invented? · · Score: 1

    Kinda like when we ask ourselves if a tree falls it make sound if noone is there to observe that. Im more akin to the "define" choice... we just put a name (numbers, operations, etc) of what is already there.

    Dont think in something like a big rock from where we take from it an statue, think in sand, water drops, etc that adds, substracts, etc. At least, for the very basic of mathematics.

    Now. mathematics is too big for a word, probably part can be counted as defined, another part is discovery, and another, invention (maybe non-euclidian geometries, or imaginary numbers fall in this category).

  11. Polluting? on Researchers Infiltrate and 'Pollute' Storm Botnet · · Score: 1

    Cant be used the botnet itself to do something more useful, like self destruct, uninstall self or display a warning to the zombie pc user?

    Maybe that borg^H^Htnet have some sort of "sleep" command to make it inactive in most part.

  12. Re:Umm...and this is NEWS??? on Pentagon Manipulating TV Analysts · · Score: 2, Insightful

    There was. If a government does wrong things, in elections they get changed. Oh, wait... in past elections they got reelected in good part because exactly this lies. So thats the famous democracy you all are proud at work.

  13. Scenario where this is useful? on Fujitsu HDD with AES 256-bit Encryption · · Score: 1

    If the encryption is transparent to the OS, means that if i, dont know, open the disk, extract the plates and read it in some way (dont know how people recover data from phisically broken hard disks), will have all scrambled. But if i take the disk as a whole, and put it in another computer, or under another OS (even booting from USB or another OS, in the same PC) the data should be shown unencripted.

    If that is right, well, dont see where this is useful. If the hard disk is stolen, could be used directly, and if not, you will lose your last chance to recover some info from it if broken.

    Or you control the encryption from BIOS/1st boot, store some key in your BIOS or somewhat near, and if you put that disk in another machine wont be possible to read it (without a keyphrase?), but still, dont see it to be very useful (if you will steal the HD, well can steal the whole machine unless is somewhat a monster).

    The 3rd alternative is that there is some existing protocol to deal with hardware encrypted media in windows/linux/whatever so is somewhat cooperative between both, at least if it supports having unencrypted partitions or you have to boot from somewhere else. But dont know it this exist.

  14. Hot! on A New Family of High-Temperature Superconductors · · Score: 0

    "High-Temperature Superconductors", the article say somewhere that "ignited a firestorm of research", and all of that because the temp at which are superconductors is 55 not celcius, not farenheit, but kelvin.

    I know that from very few over 0k to 55k there is a big difference, not sure how high they can reach, but still, looks a bit too low for "practical" implementation yet.

  15. Telekinesis on Japan's Cyborg Research Enters the Skull · · Score: 1

    Wonder what one could do with one of such implants, and a wifi/bluetooth connection to the, well, whatever you would want to move (be lost limbs or maybe something else).

    Is a bit more invasive than i.e. piercing, but could be the next big thing.

  16. Doomsday pictures on Growing Plants on the Moon May Be Feasible · · Score: 1

    "In a very distant future"... always happens there that there is something weird in the sky, like a red sun, much bigger, or not circular moon or even another sun. But is the 1st time i got the idea of a green moon on the sky.

  17. Different kinds of numbers on New Spam Site Found Every Three Seconds · · Score: 2, Informative
    Tnat a country have more or less computers that send spam could be related the amount of new people with internet connection there, specially if there is no big culture around security.

    But the 1st number, the amount new web pages related to spam, needs to be explained a bit more. The original Sophos report at least explain that are the related to the web links included with the mails, but not sure if that implies more spam realted domains, more spam related servers or if the big numbers are more related to different ways to write urls in the same servers,

  18. Heisenberg for web on Google Crawls The Deep Web · · Score: 1

    If well you can have links that do actions and change information, submitting forms is a good recipe for massive changes, from comment spam to anything, sky is the limit.

    Now you can't see what is on the web, by crawling, without changing it.

  19. Re:Cut of the source on Cybercrime Is a Franchise Model That Scales · · Score: 1

    Botnets=83.4 of ALL spam (check Marshal's Trace center) at least measured some days ago. All the other sources of spam are definately a minority there.

    Microsoft never claimed to be completely secure? Probably all the sale speech for all Microsoft products (since windows 95 or before) includes some kind of claim regarding security (usually in the form of "this is safe, anything else is not") And probably the security experts aren't the main customer base of Windows, normal people only know that it says that is safe.

    But in their licenses usually they wash pretty clean their hands taking away any possible liability.

    But still, maybe not legal, but there are responsibility in Microsoft in a lot of fronts, from design choices to marketing speech and most what is in the middle.

  20. Inciting crime? on Cybercrime Is a Franchise Model That Scales · · Score: 1

    The article seem to say that crime pays, and better (at least if you live in Romania or do security research for the bad guys) and that basically there is no punishment. That look like a call to arms for a new generation of scrip... i mean, spam kiddies.

    Not sure how much it will scale before reaching some kind of saturation point. There are some numbers that cut in some way the amount of players in the field (like 50% of all internet spam coming from just one botnet, or malware removing other kind of malwares (and even closing the doors they used to get in). But the article paints it almost as a safe bet, making it even more attractive.

  22. Botnets-spam on Top Botnets Control Some 1 Million Hijacked Computers · · Score: 2, Interesting

    There are a good chart mapping current botnets and spam at Marshall TRACE center (updated frequently afaik). That over 80% of all internet spam comes from botnets (and almost 50% of it just from srizbi) is a good sample of what is the impact of this kind of spam sources.

    Understanding something better could have a big reward.
