  1. RC4 is broken, not unbeatable.. on Russian Police Know Who Wrote Gpcode Virus · · Score: 5, Informative

    Ransomware crypto is not that effective: Backups are good, and the problem is payment is traceable.

    And RC4 isn't good for ransomware crypto, it IS broken, badly so.

  2. Chill pill people on Comcast's Throttling Plan Has 'Disconnect User' Option · · Score: 4, Insightful

    250 GB is both transparent and a real shitload of bandwidth.

    This is 7 hour a day, 7 days a week, of 720p HDTV video over Hulu. It takes a LOT to reach this point.

    Additionally, beacuse any user who gets terminated will undoubtedly ALSO terminate their cable TV and phone services with Comcast, its something that a company would not want to do lightly.

  3. Actually, this was put in place to HELP VoIP on Comcast Discloses Throttling Practices · · Score: 5, Insightful

    This was put in place per Comcast's talk at the IETF largely to IMPROVE VoIP service from Vonage et al. You look back to 2006, before this was deployed, and there were lots of complaints about "Comcast is disrupting Vonage and other voip services..."

    Those complaints largely dissapeared after Comcast started policing P2P uploads.

  4. A constant ID# is NOT meaningless... on New York Issues RFID-Encoded Drivers Licenses · · Score: 4, Insightful

    All someone needs to do is correlate your ID# with you (easy enough to do on many occasions). Once you have that, its no longer a meaningless ID number, but a unique personal tracking number.

  5. NAT is the business case killer... on IPv6 and the Business-Case Skeptics · · Score: 1

    For a long time, IPv4's limited address space looked to be a problem. And that was the #1 business case behind IPv6.

    The problem is, NAT came around at just the right time. Most businesses only need a couple of external addresses, and many end-users don't need one at all.

  6. Re:Sure it's recoverable on iPhone Takes Screenshots of Everything You Do · · Score: 1

    Forensics on RAM are much harder, because it would probably be a single cached screenshot, so you don't HAVE history, only the current ones.

  7. Unclear whether this is recoverable... on iPhone Takes Screenshots of Everything You Do · · Score: 1

    The iPhone takes a screenshot, but they never said in the FA whether its actually written to flash or not!

    Given the limited write cycles of Flash, I would hope that Apple just keeps it in RAM.

  8. Early reviews are fair to bad, not great. on Star Wars: the Force Unleashed Demo Sets Xbox Download Record · · Score: 1

    EG, the mediacritic places it down with the Incredible Hulk, and Penny Arcade harshed it.

  9. Re:Math for scaleup... on The Windbelt – a Cheap Wind-Power Generator · · Score: 1

    THen you use a mechanical generator, as it is probably cheaper to get 1W out of a OLPC-spool generator or the like.

  10. Math for scaleup... on The Windbelt – a Cheap Wind-Power Generator · · Score: 4, Informative

    40mW in 10 MPH wind for $5: Scale to 1W would take an array of 25 at a cost of $125.

    This would be, looking at his prototype, about 50cm x 100cm...

    The cost/watt however, is just astronomically bad. A 1 kW wind turbine is $3000 (which would produce ~400W at that windspeed)...

    Its really a clever idea, but just not efficient enough to be economical, even to just glow an LED lamp.

  11. Cheap and Dirty Crash Isolation... on In IE8 and Chrome, Processes Are the New Threads · · Score: 5, Insightful

    The real reason for processes instead of threads is cheap & dirty crash isolation. Who cares about RPC time, you don't do THAT much of it in a web browser.

    But with more and more apps being composed IN the browser, you need isolation to get at least some crash isolation between "apps"

  12. Uh, Google NEEDS those terms... on Google Claims User Content In Multiple Products · · Score: 2, Informative

    Otherwise, they, well, couldn't distribute your blog or your photo album!

  13. And even moreso... on HTTPS Cookie Hijacking Not Just For Gmail · · Score: 1

    CookieMonster is an active tool.

    It will take any OTHER connection the user makes on a wireless link, redirect THAT to point to http://yoursite.com/ answer that request with a SYN, and now the browser spits out the cookie.

  14. Easy to find out... on HTTPS Cookie Hijacking Not Just For Gmail · · Score: 5, Informative

    If you want to manually examine a site you visit:

    Clear all cookies.

    Log in.

    Clear all cookies marked as "SECURE" (in firefox, preferences->privacy->show cookies. Delete JUST the cookies marked as "Encrypted connections only").

    Go back to the site. Can you act as if you are logged in? If so, the site is COMPLETELY insecure.

  15. Do some math.... on Amazon Opens On-Demand Video Store · · Score: 1

    If each downloaded movie is encoded at 720p at 2.5 Mbps, thats nearly 8 hours of movies a day, or 4 rentals. 4 x $4 x 30 = $480/month in rental fees alone.

  16. Braid, challenge with low frustration... on Balancing Challenge Against Frustration In Games · · Score: 1

    Braid is proabably the best example of how to really do challenge while limiting frustration.

    In particular, "you can't die" really changes platformers.

  17. Re:NOT a fix... on Kaminsky DNS Bug Claimed Fixed By 1-Character Patch · · Score: 1

    Well, Kaminski doesn't save packets over a normal race.

    Its point is "Race until win" rather than "race once per TTL".

    Thus in a normal race for www.foo.com, you can run the race once per TTL, and then have to wait if you fail.

    With the kaminski race, you can keep running it until you succeed.

    This is why Kaminski attacks are all about glue policy.

  18. NOT a fix... on Kaminsky DNS Bug Claimed Fixed By 1-Character Patch · · Score: 4, Insightful

    This is NOT a fix to the root problem of the Kaminski vulnerability.

    The root problem is the cases where athority/additional/unasked-answers are accepted, and there are plenty of variants this "patch" does not affect. EG.

    Answer:
    whatever.foo.com CNAME www.foo.com
    www.foo.com A 66.6.66.6
    Authority:
    (usual goop).

    If www.foo.com is not yet cached (and often even if it is), this will set it as a Kaminski variant.

  19. Leap of Faith is NOT a substitute for certificates on Firefox SSL-Certificate Debate Rages On · · Score: 1

    Although I'm a huge believer in Leap of Faith, I believe it should be used in addition to, not instead of, valid certificates for SSL.

    There are just simply too many users "the first time" to any given site for leap-of-faith to be useful.

    Especially since your proposed policy ("Always leap-of-faith") would mean ANY conventional phishing site could trivially use SSL and present a nice happy lock icon, because its a NEW site from the browser's viewpoint, even though the user is fooled into thinking its his legitimate bank.

  20. Re:GOOD! on Firefox SSL-Certificate Debate Rages On · · Score: 1

    No its not. Because if you condition users to it, they will always accept it, which allows you a trivial downgrade attack to self-signed HTTPS.

    Its like the padlock icon: we conditioned the users to "see the padlock, its safe", and so all you need to do is put a padlock icon IN THE PAGE and the users think its safe.

  21. GOOD! on Firefox SSL-Certificate Debate Rages On · · Score: 3, Insightful

    Conditioning the users to accept self-signed certs is a BAD thing.

    I think self-signing is great for HTTP and with SSH-style leap of faith. But self signed is far less useful than a real cert (because even when social engineered, a real cert allows you to say "registrar X f-ed up".) for HTTPS. And conditioning users to accept self-signed certs for HTTPS is a mistake.

  22. Sorry, WRONG on Developer Praises Complexity of Time-Based Puzzles In "Braid" · · Score: 1

    Its "Developer praises game that he had nothing to do with".

    Its a professional critic review.

    And braid is as mind-blowing as everybody says.

  23. Re:UNLESS YOU CHECK, you are insecure! on A Good Reason To Go Full-Time SSL For Gmail · · Score: 1

    The article is WRONG:

    The GX cookie will be set to secure, but an attacker can STILL cause problems unless you set the preference, because if the attacker redirects you to http://mail.google.com/ it STILL WORKS. I just created a new default account, logged in through https:/// and you can get the browser to go through http:/// just fine.

    Unless you set the preference, explicitly, you are vulnerable to mike perry's attack.

  24. Because... on A Good Reason To Go Full-Time SSL For Gmail · · Score: 1

    Google waited for a YEAR before doing anything, and only added the preference about the time when they heard of Mike's talk, "Exploiting 365th day vulnerabilities..."

    Its not like google hasn't had ONE YEAR of warning on this!

  25. Re:already does that. on A Good Reason To Go Full-Time SSL For Gmail · · Score: 1

    Actually, that doesn't work.

    You see, Google doesn't set GX as secure unless you manually select the preference to "Always use secure".

    Thus even if you are a good user and always type in https, unless you changed the preference, Mike's tool can read your mail!
