An introduction to network packet analysis

10/21/15 Attacks on Network Time Protocol can defeat HTTPS and create chaos
Exploits can be used to snoop on encrypted traffic and cause debilitating outages. Serious weaknesses in the Internet's time-synchronization mechanism can be exploited to cause debilitating outages, snoop on encrypted communications, or tamper with Bitcoin transactions, computer scientists warned Wednesday. The vulnerabilities reside in the Network Time Protocol, the widely used specification computers use to ensure their internal clocks are accurate. Surprisingly, connections between computers and NTP servers are rarely encrypted, making it possible for hackers to perform man-in-the-middle attacks that reset clocks to times that are months or even years in the past. Attacking the Network Time Protocol, researchers described several techniques to bypass measures designed to prevent such drastic time shifts. The paper also described ways to prevent large numbers of computers from successfully connecting to synchronization servers.

Rigged Markets:
What exactly were those Federal Reserve lockup rules? Were organisations allowed to transmit information out of the room before 2 p.m. or not? The Federal Reserve won't say. A Fed spokesman declined to answer that question from CNBC. So we do not know if this was actually allowed or not. So it is difficult to understand what happened because the rules do not seem to be very clear and are not publicly available.

10/2/14 Global Infrastructure explained by Retired NSA Technical Director William Binney. Binney also mentions how the current NSA mass surveillance regime differs from aspects of an earlier less expensive program, called THINTHREAD, which both he and the former NSA senior computer scientist, Edward Loomis, invented. The presentation contains Binney's own slides and published documents released to journalists by Snowden.
The major collection of data occurs and it's done under Executive Order 12333-- not under FISA 702 or the Patriot Act or any of that. It's all done under one -- Executive Order 12333.
The phone network-- the phone switch telephone network. That includes satellite phones, and mobile phones, and everything, worldwide-- it's all numbered. There's a number scheme for it.
The entire world is broken up into nine zones and these are the numbering schemes for those zones. If you dial a number from the U.S.-- '01' or '011'-- then the zone of the world you want to call. If it's 3 or 4, you're going to Europe-- 7, Russia, and so on.
So I mean, the entire number scheme tells you exactly who you you have on the line-- these are machines passing it, so they have to have this data both ways, so they can route to and back. The machines do this. So if the machines do this, you know?
I mean, how could [Keith] Alexander [former director fo the NSA] come up and say, "I don't know if it was in the United States." When in fact, the machines have to know, okay? You have to, or it doesn't get through. It is the same with the Internet. Both IPc4 and IPc6 addresses are assigned by ISPs that obtain allopcations from a local Internet Registry or national internet registry ARIN, RIPE NCC, LACNIC, AfriNIC, APNIC.
They have to make the job look complicated. It's not complicated at all. They're real simple. And the in the Internet world, it's-- you know, IP address out of the IANA [Internet Assigned Numbers Authority] or the ICAAN [Internet Corporation for Assigned Names and Numbers], you know. So, I mean-- the Internet world is divided into five zones, right? And you just block assign different number blocks to these different zones. Then it's subdivided down from the regional authorities-- down into the country authorities-- down into the service providers in local areas. So even if they want to assign an arbitrary number, that arbitrary number still tells you what zone of the world it is. And even if you look at the assignment and sub-assignments, you can get even further down in that.

Neustar runs the number portability database. The battle over the little-known routing network reflects the central role that the phone companies play in the government's surveillance and phone-tracing capabilities. The phone-routing system grew out of a 1997 law that allowed cellphone and landline users to keep the same number even when they switched carriers. These so-called portability standards made things easier for consumers but created potential complications for intelligence and law enforcement officials in tracing phone calls and determining which numbers were tied to which carriers. The routing network that was put in place, with Neustar as its administrator, was designed partly to allow the government nearly instant access to the data on where calls were being routed. Law enforcement agencies regularly query the database when setting up wiretaps. Under the Ma Bell monopoly, keeping track of phone numbers fell to a unit of the old AT&T. As part of the 1984 breakup of Ma Bell, the unit was spun out as a separate company that eventually became Telcordia and was bought by Ericsson in 2012. After the industry fragmented and Congress in 1996 allowed people to keep their local phone numbers when switching carriers, a separate, central database became necessary. Neustar won a portion of the contract when the database was created in 1997. Customers who switch carriers now just have to wait a couple of minutes while Neustar's database is pinged and the number is reassigned. There are more than 800 million numbers in use in the U.S. Numbers not in the database would be landlines that have never switched owners or have never been acquired by other providers through mergers and acquisitions.


Networks: The 10 Most Bizarre and Annoying Causes of Fiber Cuts

When asked to name one of the great things about our network, I have to say it's our fiber footprint. With over 57,000 miles of intercity and 27,000 miles of metro fiber, our footprint is a grand design of both buried and aerial paths. It makes us unique, but with that also comes one of the worst things about our network, and that is the different types of damage we see to our fiber plant. From errant excavators to crazed squirrels, there are so many different ways to wreak havoc on our network, it boggles the imagination! August 4, 2011 By Fred Lawler

5/4/14 Observations of an Internet Middleman
Our Internet Services product sits on top of this global infrastructure: The orange lines are cable systems that Level 3 built and fully owns (the yellow lines are owned by multiple carriers or leased). That means thousands of miles of fiber in trenches across land and thousands of miles of fiber in cables on the seabed. In all, our network contains approximately 180,000 miles of fiber - enough to circle the equator seven times.
That fiber is then turned into usable bandwidth by installing equipment in data centers in each of those red and yellow dots, and also roughly every one hundred miles along each terrestrial cable. That bandwidth is then turned into an Internet Service by installing routers and switches in key locations. The Level 3 Internet Service consists of more than 10,000 Ethernet connections - getting bigger every month. The original invested capital in the Level 3 network was approximately $40 billion.

5/8/14 Comcast is the one who should pay for network connections, Cogent claims. Hearing on Comcast/Time Warner Cable merger brings up competition complaints. Internet backbone operator Cogent has long expressed its displeasure with Comcast's demands for payment in exchange for accepting Netflix video and other traffic. Comcast has argued that the data Netflix sends into its network creates an imbalance that should be rectified by payments from Netflix and its transit providers like Cogent. Netflix decided to pay Comcast—but Cogent has held out. Today, Cogent CEO Dave Schaeffer made a different argument, saying that Comcast is the one who should be paying for connectivity.

    In one of the more audacious and ethically questionable research projects in recent memory, an anonymous hacker built a botnet of more than 420,000 Internet-connected devices and used it to perform one of the most comprehensive surveys ever to measure the insecurity of the global network.
    In all, the nine-month scanning project found 420 million IPv4 addresses that responded to probes and 36 million more addresses that had one or more ports open. A large percentage of the unsecured devices bore the hallmarks of broadband modems, network routers, and other devices with embedded operating systems that typically aren't intended to be exposed to the outside world. The researcher found a total of 1.3 billion addresses in use, including 141 million that were behind a firewall and 729 million that returned reverse domain name system records. There were no signs of life from the remaining 2.3 billion IPv4 addresses. All data collected during the Internet Census 2012 is available for download via BitTorrent. It is released into public domain so everybody can use it for any purpose. For an explanation of what this data is and how it was obtained,

*The following lists the top ten language in use on the Internet, and how rapidly they grew from 2000 to 2005.
Given how little the .com boomers paid attention to the fact the Internet had already reached 50% of the United States back when, I should warn you that NONE of the listings below can double the percentage again once they have gotten close to 50% penetration!
I know this seems obvious, but somehow all those billionaires in the .com boom figured out a way to miss it, went down in flames!

Take English, for example:

At a 28% penetration level, even if you managed to get every one of the English speaking people in the world on the Internet from 2005-2010, the next such study could NOT show two more doublings of this percentage. . .at 25% you will just barely theoretically be able to double twice more, but that's only theoretically.

China, at just over 9% could double only three more times, but a fourth doubling would be impossible. . .however, just ONE double from now will likely put Chinese ahead of English as the default language of the most Internet users.

Chinese Doubling

Even Dutch, at only 1.5% of the world, can never double again, as their penetration is already well over 50%, as are various Scandinavian languages that have high penetration but too low a population to make such charts.
