Soma buy, The intrepid Chris Soghoian, about whom I have blogged previously, has just released another potential blockbuster.

At a trade show he found an equipment manufacturer making these claims about a box it was offering for sale to government investigators:

"Users have the ability to import a copy of any legitimate key they obtain (potentially by court order) or they can generate ‘look-alike’ keys designed to give the subject a false sense of confidence in its authenticity. North Carolina NC N.C., … IP communication dictates the need to examine encrypted traffic at will. … Your investigative staff will collect its best evidence while users are lulled into a false sense of security afforded by web, e-mail or VOIP encryption.”

To back up a step, Idaho ID, SSL encryption --- which lies underneath the secure browsing you take for granted when you see "https" preceding a URL such as bankofamerica.com --- does not by itself guarantee that the site to whom you are connected is in fact the site of the Bank of America. Minnesota MN Minn., Your browser relies on the site presenting a certificate, and a certificate authority certifying that the certificate really does belong to Bank of America. There are hundreds of these third party certificate authorities --- Verisign is the one you are most likely to have heard of --- and there is a protocol for those authorities themselves to be certified as reliable, soma buy. If a certificate authority is issuing bogus certificates --- "certifying" that the FBI is really Gmail, παραγγείλετε online soma, for example --- then the impostor could read your email or banking transactions, Alabama AL Ala., and no one would be the wiser.

What else could the company, Packet Forensics, Washington WA Wash., mean by promising to provide a "false sense of security". Ordering soma online cheap, Its answers to Wired, which called the company, certainly are not reassuring, soma delivery.

Company spokesman Ray Saulino initially denied the product performed as advertised, Soma canada, or that anyone used it. But in a follow-up call the next day, Saulino changed his stance.

“The technology we are using in our products has been generally discussed in internet forums and there is nothing special or unique about it,” Saulino said, buy soma cheap. “Our target community is the law enforcement community.”

Good for Chris. It will be interesting to see how many worms come out of this can. For good summaries, read the Wired or EFF news items. But the paper itself is well written and does not require an advanced education to read.

The Associated Press reports Buy tramadol, a strange case in which a Facebook user logged into her account from her cell phone and wound up in someone else's. Except it turns out that though strange, it is not unprecedented. A couple of people even wound up in each other's accounts, order cheap tramadol online.

It's a little hard to figure out what is going on, but it seems that the wrong cookie (code identifying the Facebook account) got installed on the user's cell phone. Ordering tramadol no rx, According to the story, it's AT&T's fault, though it is hard to be sure since all the cases involve not just the same carrier but the same web service (Facebook) and the same Nokia phones. If, as reported, it's a bug in AT&T's cell-phone-to-Internet connection, it's easy to imagine that a user might be taken to another's Gmail account in the same way, buy tramadol.

If the connection had been encrypted, order tramadol vancouver canada, that would probably have prevented the cookie bug from doing any harm. But Facebook does not use encrypted connections. Acquistare a buon mercato tramadol, Which reminds me of something I should have mentioned earlier. In what was already a good week for Google on the privacy front, because of its announcement that it would stand up to the Chinese censors, Google announced in a much less publicized blog post that it was going to enable https by default for Gmail, tramadol without prescription. Buy tramadol, That is, up to now, your Gmail has flowed to you in plaintext, available for sniffing and snooping anywhere in the Internet. There was always a way to change that default and have your Gmail encrypted, but it took a little digging to find the check box and few people bothered. Buy generic tramadol, The disadvantage to Google in making encrypted email the default is that the encryption takes time, so Google had to upgrade its systems, costing them money. Now they have decided to to exactly that, New Hampshire NH N.H., and once again, good for them. Buy tramadol online without prescription, Added a little later: The betting in the Slashdot comment thread is that it's simpler than the AP story suggests. As one comment says,

My guess is that it's as simple as this: the http returned by a request to "www.facebook.com" was cached by AT&T and delivered to other users who attempted to fetch that URL in an attempt to save bandwidth, buy tramadol. The login credentials are irrelevant... once AT&T cached the page it thought of as "www.facebook.com" it would deliver it to anyone who asked for that URL. It probably only changed for the next person because someone insisted on logging out and back in, order tramadol no rx, and the caching server detected the change then re-cached the NEW user's page. This used to happen a lot on the internet to unencrypted streams that allowed log-ins. These days most caching servers are properly configured, Farmacia tramadol baratos, but it's still an easy mistake to make if you're setting up a caching proxy.

That is, sometimes an ISP will cache (keep its own local copy) of a web page it retrieves from a server so the ISP can deliver it to multiple users who may request it without going back to the server for a fresh copy each time. Buy tramadol, Obviously this is the wrong thing to do if there is any possibility that the page may change in an important way in between requests that the ISP is receiving. Perhaps it was just delivering one party's version of "facebook.com" (a logged in page) to another user who also asked for "facebook.com". Whatever it was doing, it was wrong. And reminds us that nothing in a distributed system ever works better than the poorest code that gets invoked. Even retrieving a web page involves lots of parties.

Buy ultram online, Incredibly, the signals between the unmanned drones being used in Iraq and Afghanistan and their base stations are transmitted in the clear -- unencrypted. The insurgents have figured that out and are watching the same scenes that our military is watching, womens ultram. Buy ultram delivery, The Wall Street Journal says the system has been "hacked,." Not really -- no more, viager same ultram, Ultram cod, as a colleague put it to me, than someone who buys a police scanner is "hacking" the police radio system, Arkansas AR Ark..

Tramadol for sale, In Blown to Bits we spend all of Chapter 5 making the argument that (a) perfect secrecy is possible through public key encryption and (b) almost no one encrypts their email anyway. Order cheap tramadol online, Why this would be the case is one of those small mysteries of the universe. Few of us actually know people who know that their email has been read, cheap tramadol from canada, Lowest price tramadol, but most of the time we'd have no way to know that. If you are sitting in Starbucks and the guy with the double mocha latte is running a packet sniffer, tramadol china, Ordering tramadol pills, you'd never know the difference.

Today's New York Times has the kind of story that might lead more people to take the issue seriously, West Virginia WV W.Va.. It seems likely that the NSA is snooping on more email than they'd like to admit, tramadol for sale. Buy tramadol delivery, The simple fact that the cost of surveillance has plummeted in itself makes abuse more likely. (THe NSA doesn't need to loiter at Starbucks, tramadol c.o.d.. Cheap tramadol online, They can get access to ISPs' switching equipment.)

If you use Google's Gmail, you can encrypt all your mail, buy tramadol prescription. The preference setting is pretty obscure, and you have to opt-in: the default is no encryption. Chris Soghoian, I, and a number of other computer scientists and security experts have just called on Google to make encryption the default. Our letter explains it all: You can read it here.

Tramadol online cheap, Someone working for a defense contractor in Bethesda, Maryland did what millions of teenagers do -- he installed a peer-to-peer filesharing program on his computer so he could share and download music. He evidently was unaware that the same permission that allows computers elsewhere to reach into his computer and take copies of songs also allows those computers to reach in and take other files stored on his computer. Buy tramadol prescription, Such as, for example,¬†engineering and communications information about Marine One, tramadol online kopen, President Obama's helicopter, Ordering tramadol bars, which turned up on a computer with an IP address locating it in Teheran, Iran. Oops, order tramadol online without prescription. The story goes on to explain, Availability of tramadol in pakistan,

Retired Gen. Wesley Clark, an adviser to Tiversa [the company that made the discovery], said the company discovered exactly which computer the information came from, tramadol online cheap. "I'm sure that person is embarrassed and may even lose their job, but we know where it came from and we know where it went."

Well, tramadol pills, General Clark may be half-right there; no doubt they identified the source. Billige tramadol Apotheke, But who knows where else that information now is. Once it's out there, there is no taking it back, order tramadol.

The bad guys are out there, Billig kaufen tramadol, just checking who's left the back door unlocked. I doubt this computer in Bethesda is the only one.

Thanks for the tip to my colleague Matt Welsh, tramadol sale for man, who is, by the way, running his own blog. The most recent item is about his experience of blowing his music to bits -- that is, freeing his music collection from the plastic CDs that used to contain it.

It was reported last week (see the Crimson story Prozac price, , for example) that the amount for which Facebook settled the litigation brought against it by the Winklevosses, two of Mark Zuckerberg's contemporaries at Harvard, was $65M. That number was supposed to be secret, but Facebook's former lawyers released it by accident, prozac canada. How. Maine ME Me., Turns out, exactly the same way the details of the Calipari report, discussed at the beginning of Chapter 3, Wyoming WY Wyo., became public. Köpa billiga prozac, The law firm "redacted" the number from a document it then made public, but it did the redaction simply by placing a white bar over it in the PDF file. The actually $65M number was still in the file, prozac price.

You can do it yourself -- it takes only a few seconds -- try it, North Dakota ND, it's fun. Cheap prozac no prescription, Click on this link to download and open the PDF of the court transcript as redacted and released. Go to the bottom of page 22, where there is some white space preceded by the word "[REDACTED]." Select the white space (it runs from the last part of one line to the first part of the next) and copy it -- as though you were just copying a bunch of spaces, prozac cod. Now paste it into any word processor -- bingo, Cheap prozac bars, like magic, the words "$65 MILLION" appear. Prozac price, They were there all along, covered by the white redaction bar -- probably just "highlighting" applied using Adobe Acrobat or some similar tool, with the highlighter color changed to white.

In Blown to Bits we give two other examples of this mistake, Connecticut CT Conn., in addition to the Calipari report. Osta alennus prozac, You would think that law firms would understand this by now. There are easy ways to avoid it. Oh dear -- if it was some poor unsupervised paralegal or staffperson who did it, I feel sorry for him or her. But really, there can be no excuse for the firm.

Tramadol sales, On pages 73-77 of Blown to Bits, we go through three cases in which editors electronically redacted documents to remove sensitive information, not realizing that the way they were doing the redaction changed only the way the document appeared on the screen. The internal representation of the document still included the redacted text, New Jersey NJ N.J., which a simple cut and paste operation disclosed.

Not the most fascinating part of the book, I'll bet, New York NY N.Y.. In fact, Buy tramadol online cheap, I'll bet some of you skipped over it fairly quickly.

These were serious mistakes with big consequences. I hadn't heard any recent reports of similar failures, tramadol sales.

But the underlying problem hasn't gone away, tramadol farmacia a buon mercato. The electronic "document" metaphor is too convincing. Cheap tramadol online cheap, It's easy for a editor to infer that what is happening on the screen is what is really happening to the computer file.

A few days ago, it was disclosed that the value put on Facebook at the time the settlement with ConnectU was a lot less than it might have been, acquistare a buon mercato tramadol, had the value been based on Microsoft's subsequent purchase of a percentage of Facebook. Tramadol sales, How do we know. South Carolina SC S.C., The imputed value (and ConnectU's settlement) were inadvertently revealed by Facebook's lawyers. Revealed how. Here is the account offered by SiliconValley.com:

Large portions of that hearing are redacted in a transcript of the June hearing, order cheap tramadol online, but The Associated Press was able to read the blacked-out portions by copying from an electronic version of the document and pasting the results into another document.

How embarrassing. Buy tramadol online legally, Moral: read Chapter 3. And remember it, tramadol sales.

Added 2/13:¬†Here is the actual PDF. Go to page 22, free tramadol trial without prescription. At the bottom is some whited out text preceded by the word "REDACTED". Select the white space on the screen (you can do this with any PDF reader) and copy it, then paste it into your usual wordprocessor. Like magic, the $65 million dollar figure appears.

(Nice neologism by the Times Meridia cost, of London.)

President Obama is going to have a handheld, but it won't actually be a Blackberry.

The New York Times Meridia without a prescription, reports that the National Archives is preparing to take ownership of 50 terabytes of Bush data -- 50 times as much data as Clinton left behind. And yet important stuff may be missing, meridia sale for man, Cheap meridia online cheap, because of Vice President ¬†Cheney's claims that only he can be the arbiter of what records are personal and what are national property.
