Final Post

No – I’m not dead yet!!

This is a final post at Tigerstail.wordpress.com because I am tired of seeking knowledge and bitching about that which is. It is time to use my skills to develope the solutions to all of the problems I have discovered.

Resistance is Futile!

Once you realize that Resistance is Futile, knowledge truly is soporific. The problem is, life without knowledge acquisition becomes somewhat boring. After all how much, sex, booze,beach time and loud music can a sing person handle. So for various reasons such as the potential for my liver falling out and fear of going brain dead, I decided to sober up and read the content of all my emails from Sans to see what I’ve been missing since April. The following is extracted from various Sans newsletters and attracted my attention because of the “unique” content.

WINDOWS SECURITY
Researchers at the Internet Storm Center estimate that it takes about
four minutes for an unpatched Windows PC to be compromised once it
connects to the Internet. The survival time has consistently dropped
over the past years due to the increasing number of worms and viruses
and hackers using more and more automated attacking tools. However, a
researcher with the German Honeypot Project claims the survival time is
much higher than 4 minutes and in fact is nearer 16 hours. Either way its less than one day on line.

Google can’t stand the competition
A controversial law was narrowly voted
in last month and allows Swedish security services to eavesdrop on all
international calls into and out of Sweden. In response to the new law
TeliaSonera, the Finnish-Swedish telecoms operator, has moved its
servers from Sweden to Finland and Google is also considering a similar
course of action. After all, why should Google allow anyone other than Google to snoop on your surfing
habits and keep a history of your actions

Google Caches Retain Stolen Data
Stolen sensitive personal data, including financial account information,
have been found to linger in Google caches for months even after the
server holding the stolen information has been disabled. Cyber
criminals collect information through keystroke loggers and store the
data on servers. When the servers are discovered, they are taken down,
but the Google pages are not unless specific requests are made. A
Google spokesperson said that in general, the company does not remove
cached information, but that it eventually disappears on its own after
the original source is no longer accessible.

Coming to America!
Phorm’s technology can be
used by Internet Service Providers to track end user activity on the
Internet and place advertisements based on their online activity. Phorm
already has agreements in place with some of the U.K.’s top ISPs such
as the BT Group PLC (BT), Carphone Warehouse’s (CPW.LN) Talk Talk and
Virgin Media.

Expanding the Patriot Act
The Foreign Intelligence Surveillance
Act (FISA) allows for warrantless surveillance of
telecommunications and immunity from subsequent lawsuits served against
the telecommunications companies facilitating the surveillance. A
lawsuit claims that FISA breaches the Fourth Amendment of the U.S.
Constitution, which prevents the government from unreasonable searches
and seizures. Supporters of the law claim it is a vital weapon in the
fight against terrorism.

Don’t Xerox any $3 Bills
A feature built into many modern laser printers is raising concerns
among civil liberties groups that individuals’ privacy may be eroded.
The feature uses technology to print hidden yellow dots that are unique
to the printer onto each page. These dots are invisible to the eye, but
when viewed under a blue LED light they can identify the printer and the time of use. The
technology is used to track those who attempt to use color laser
printers to create counterfeit money. However, privacy advocates are
concerned that the technology could be misused to track and identify
whistleblowers or dissidents in totalitarian regimes.

Read it and Weep!

Vista Blue Screen of Death!

Did you ever wonder what Microsoft personnel call the world famous “Blue Screen of Death.” Well at least one programmer must have a sense of humor or submitted the following error message as a resignation.

The biggest improvement over Windows 98 and Windows Me is that the Blue Screen is a quick flash before the computer goes dead whereas in the old days it would stay on your monitor to torment you. None of my friends can recall a blue screen effect with Windows XP SP2 so Vista must be engaging in a nostalgia trip.

Live Linux CD -Dead Computer

It appears that linuxcrayon has the gift of prophecy or maybe just hard earned knowledge. I was using a Live CD to track the code on some disgustingly evil sites. Even though it was a Live CD on a minimal machine (no hard drive), I’m still in the habit of monitoring netstat to see who’s monitoring me. Now I was a little surprised to find that I had probes from carnivore and a couple of corporate spies watching me surf crap.

I wasn’t too worried as every time I turned the machine on it came back as a brand new machine with no tracks. On a regular machine with permanent programming, the Spyware is there the moment you turn the machine on so it’s pretty hard to find out where you caught the crap once you’ve got it. With a Live Linux CD, every day is a new machine with no history so you can start surfing while watching netstat and see where you get your invaders. If you miss it today you can try again after . Trust me, if you pick up military strength malware on a regular machine, you can never shake the crap so it’s tough to track it to the source.

Well pride about my cleverness came right before my fall and the knowledge of Linuxcrayon was predictive. I was using a Knoppix operating system and a Firefox browser and it started getting unstable. I switched to a DSL (Damn Small Linux) operating system and their proprietary version of Firefox. The stability lasted a few days and I thought that it was a malware injected into memory much like the Firefox Browser update which occurs every time you start-up a Live Linux CD and open the browser. But then everything went to hell.

I could no longer enter the Bios on start-up, Flashing and resetting the BIOS didn’t help and the system would not operate off line. So what ever damage was being done was permanent and not due to imbedded software. Then the machine just stopped working. Post card says my CPU is fried.

Well this noble machine had been through a lot. It started life as a windows machine which was slammed during the trial as I investigated various evidence sites which were still online. I gave the hard drive the lots wife tratment and replaced the CD drive and tried to rebuild it as either a windows machine or a LInux box to no avail. It was unstable. As a medium for running a live CD, the machine hung on for another 3-4 months doing reconisance on a lot of shit sites. and publishing the results. It was on this machine that I discovered Google Dorking 4 Kiddie Porn and exposed sites which should be Hacked to death.

Just for laughs, I have purchased a couple of motherboards and hope to return this box to active duty.

GSI 4 Firefox – Cool Tool!

Sometimes you trip on Browser add ons that are a fantastic idea. I mean you hit a site you want to explore and you can click the page links, get lost and never explore both the depth and breadth of the site. You may leave without finding what you want. What the Google Site Index does is draw a site map based on Googlebots knowledge of the public area of the Web site. Now certain cites like youngerbabes.com and young-models.org (which can’t be searched with the site command) cannot be indexed. Others which have thousands of pages like thehun.net yield a very organized site index which is less than a page.

Installation is simple, and once installed it’s easy to use. Just click on tools and open up GSI (or right click on the screen) and up pops the interface. Confirm the Domain, click start and the site is indexed. You should probably stay away from the recursive search as after trying twice with two different sites, it locked both times. Then Google accused me of having a virus and locked me out until I entered some twisted letters.

If I have a complaint, the results pop up as a html page that you can only click on one link before it disappears. The workaround is to save the page as html on your desktop and work from there. If you have basic HTML skills, you might want to open the page in notepad and cut the script at the bottom before you start exploring the site. While GSI indexing is totally anonymous, your site visits are not unless you do the standard Google trick of saving the URL’s in notepad and using the Google cache while stripping all images or by using a proxy.

So far, I haven’t used GSI for anything serious if you don’t count looking at the good, the bad, and the ugly architecture of my own Web sites.

Dissecting a Kiddie Porn Cookie

Cookies can be used to transfer information about you to a website. Now when I started to use a Live CD, I got a little bolder in tracking source code on nasty sites and not shutting down between site visits. After all no permanent images would be stored and there wasn’t all that much information which could be transferred from a machine with no permanent memory of where it had been and what it had seen.

Well I found out there is an awful lot of information in temporary storage. like a cookie from any personal site you have visited, ie gmail, hotmail, hi5, myspace, facebook etc. Since I really hadn’t thought about it and therefore wasn’t avoiding it, I was able to get a peak at what kiddie porn sites wanted to learn about me.

From over at Fatsavage.wordpress.com, the original analysis of the cookie from americanthumbs.com was:

‘ucjc=xucjcxnoref
xucjcxnoref
xucjcx1
xucjcx0
xucjcx0
xucjcx
xucjcx; path=/;’

Now after a session of Google hacking for kiddie porn, I ended up with the following cookie from billpics.com or amglover.com which both use the ucj cookie.

‘ucjc=xucjxnocookie
xucjxnocookie
xucjx1
xucjx2
xucjxnone
xucjx|teens-girls.net|mymasha.com
xucjx; path=/;’

It would seem that a couple of sites I had not suspected of kiddie porn were of interest to the people from UCJ as both of their names show up as a variables in the cookie and the variable that was a 0 has now moved up to a 2. I guess they are counting the nasty places I had been. Apparently, I was cautious in this surfing secession as the “noref” variable had shifted to “nocookie”.

When I got sloppy, the changes in the cookie got really interesting.

‘ucjc=xucjxgoogle.co.vi
xucjxhttp://http://www.google.co.vi/search?hl=en&client=firefox
&rls=org.mozilla%3Aen-US%3Aunofficial&q=hq-teens.com&btnG=Search
xucjx1
xucjx0
xucjx0
xucjx
xucjx;

Well, I sort of figured this would happen so I had turned the machine on and went nowhere else except the Google search bar. Now in addition to my IP, they have my Google cookie, the country version of Google, that I search in English, that I’m using Firefox and that I pressed the search button while looking for information on hq-teens.com.

If I had checked my Hotmail or Gmail prior to the search, they would probably have my user name and everything else.

Tag I’m it, wandering in a forest of honeypots with Federal bees swarming to sting.

Why use a Virtual Machine?

Well their is good news and bad news about simple Virtual Machines. At it’s simplest, a virtual machine is just a live Linux CD on an old computer without even a hard drive. The one I’m currently using has a motherboard with a fried BIOs and an embedded Trojan but Linux does not rely on the BIOS and Trojans rarely are cross platform.

With a live Linux CD, you don’t need a storage area and with a gig of RAM, you can quickly surf without worrying about porn loaders or malware of any sort. The nice thing is there is no permanent record in hidden index.dat files or in log files written in geek. Shut the machine down and everything you did is gone including all cache files of images, cookies and history. Since possession of weird shit is the major crime and the easiest to prove with the un-erasable hidden files on your hard drive, you avoid that trap. Unbelievably, your hard drive holds a near permanent record of your surfing history and a copy of every image you have ever seen whether on purpose or not.

So on one hand you get some element of protection but on the other hand there is still information being conveyed to anybody that wants to spy on you. First, at the local level we have the FBI’s ability to spy on every private citizen in America. The powers of Carnivore and Echelon to track all of your surfing activity whether wired or wireless are incredible. I wouldn’t bet that a keystroke logger won’t work on a virtual machine. After all, my virtual machine uses an older version of Firefox which accepts an update and installs it in RAM. Not much different than accepting a keystroke logger with “ET call home” capabilities which would report on all of your surfing habits, emails, and instant messages. Since wireless intercepts are up close and personal and Carnovor is nestled at your ISP level, I’m not even sure that a proxy will help to hide your surfing activity because the spying is already done by the time you request reaches a proxy. (a keystroke logger even defeats encrypted URL’s)

This is one of those classic Mexican stand-offs. You will be observed and unless you are actually making kiddie porn or building bombs, I doubt that anybody would really want to explore spy technology at a trial because the Government’s technical capabilities of information gathering is probably being illegally used. It’s far easier to trash your machine, get you to a repair shop, and let you self incriminate as the courts have ruled that you have no expectation of privacy when you take a machine in to get it repaired so any evidence on the machine can be used to set you up. This is the biggest advantage to virtual machines- they dont go to repair shops.

While there is no evidence on your machine that you are engaging in dangerous activity, never assume there is no evidence at all.

I got a little bolder on my virtual machine and found out just how much information can be gathered from a virtual machine which allows cookies. (If you don’t allow cookies, you can’t explore many sites and as soon as you allow them there is information being transfered.)

Content Filtering the Fatsavage.

Just because your site traffic drops, it does not mean that their is evidence of Content Filtering. In my last post, I described two blogs which are so dormant that their are no visitors and the information is so stale that there are few Google referrals. Still, this type of stagnant site does not happen overnight. It’s like turning an oven up or down. If you turn it up to speed cooking, it will take 15 minutes or so before you see the obvious effects and when you turn it off, the meal will keep on cooking as long as the temperature is above 140 Fahrenheit.

Following the procedure outlined in the last post, we can check for a stable relationship between site visitors due to Google referrals, regular visitors and how much of a viral effect there is. It’s pretty obvious where the break in the following data is, but even this part of the analysis does not prove that a sudden change occurs, it just proves there is a stable relationship.

Google referrals———–Total Visitors
141———————–291
113———————–231
123———————–250
157———————–340
102———————–231
45————————115
33———————— 81
37————————103
37———————— 92

The relationship is as follows with an incredible correlation coefficient (R squared) of 99%.

visitors equals 1.93(Google Referrals) plus 23.4(Regulars)

At this point, we know we have a stable relationship between visitors and Google referrals and the drop is obvious but is it significant enough to prove Google Content Filtering.

Well for the 21 days prior to the day with 340 visitors there had been a relatively constant rise starting from 112 visitors a day. The equation was:

Visitors equals 7(Day) plus 109(Regulars)

Now the correlation coefficient was somewhat low at only 67% but considering day to day variations in frequency of posting and the strength of the content, that is still a strong relationship. The weaker correlation lead to large Standard Error of the estimate of 32. Putting this in layman’s terms on a day where you expected 200, 95% of the time it would be between 136 and 264, and 99% of the time it would be between 103 and 297.

This broad range seems like we are shooting at the broad side of a barn but after the 24th day when we would have expected 277 or above 180 at the 99% confidence level we only had 115 visitors and after that it got even worse.

It’s pretty obvious, that there was a change and my most popular post at the time could no longer be found short of a direct entry of the title which was “Youngerbabes.com Hack This Site”. I can’t figure out why a rant about a know kiddie porn site which is still on line should have been blocked unless it’s protected government property.

Google Content Filtering in America!

If content filtering exists in America, there ought to be a way to prove it one way or the other. Any experiment should be open to the public with all assumptions identified and the experiment should be reproducible and have a scientific evaluation criteria.

As a working assumption, there should be three elements to the number of site visitors when averaged over time. First, there should be some measure or regular visitors who would average out over time to some relatively constant value. Next there should be a feed from the search engines which is a factor of the public interest in your topic. Also, there could be a viral effect where visitors recommend you to others and therefore one site visit by Google referral or one regular visit may translate into any number of visits. (This is probably highest with jokes and politics and lowest with technical). However, if both groups (regulars and referrals from Google) recommend you to about the same number of people, this doesn’t alter the mathematical approach.

For the past three weeks, this site has varied around 41 to 87 visitors a day with an average around 60 a day but WordPress only holds the search engine data for a week. So I have the following Google Data and site visitors.

Google Referrals—–Visitors
44——————53
51——————67
44——————64
48——————62
50——————75
33——————48
40——————54

Now I ran the above data through an online Linear regression tool and came up with a very high correlation coefficient of 86% (R squared 75%). For a moment just think of a fat reduction pill where the weight you lost was 75% related to the pills you took and independent of all other variables like food and alcohol consumption and exercise or other variables.

The equation is visitors equals 1.3(Google Referrals) plus 4.1(regulars)

Obviously no viral effect and a small number of regular visitors, but if you need the technical information you come because of a Google search.

Now the data is drifting down because the site has not been very active for the month but the average for the data above is 60 with a two standard deviation range of 42 to 78. I would be hard pressed to make a case for effective Content Filtering based on this data set because there is no sharp break in the curve and the number of visitors for the past week is much the same as it’s been for the past three weeks.

Just for fun, I have two very dormant sites one in business (2.6 visitors a day) and the other in recreation (5.4 visitors a day). The equations and correlations are as follows:

visitors equals 1.4(Google Referrals) plus NO(regulars) correlation coefficient 95%
visitors equals 1.0(Google Referrals) plus 1.8(regulars) correlation coefficient 89%

Once again there is no sign of content filtering as the sites just suffer from a lack of interest, both mine in writing on the topic and visitors needing information on the topic.

Content filtering is an on-off switch which is turned on when the content gets out of hand so there should be signs of a dramatic drop in traffic.

At Fatsavage.wordpresss.com I have seen three cases of dramatic content filtering over the past 6 months with two in the past month. Start reading at the home page and work backwards to December 18, 2007. In that short month (about 12 posts), I managed to piss of the Feds twice and been slammed by provable content filtering. Now, I was attempting to be offensive with all of it, but I failed 10 times as only two posts were serious enough to get blocked.

Can you figure out which two?

Screwing up XP!

I’ve sort of been suggesting that part of the reason that Vista has not been universally accepted is because Windows XP is a mature, sable and secure operating system which has no need for a replacement except perhaps in the gaming community. There are many independent companies that understand the system and are writing independent security software to defend you against Virus, malware and to secure your privacy against unwanted preservation of sensitive data or images.

The truth is you can do a pretty good job of defending your machine by using Firefox as your browser with settings that insure your privacy and erase all surfing history. Naturally, you can back this up with Ccleaner and an independent antiviurus and your in pretty good shape. You may want to use your traditional XP search function to check for cookies that may have been missed and to check the images in all hidden and back-up files. After everything unwanted has been eliminated, defragment your system and overwrite your unused space with a seven pass disk wipe.

From what I know of forensics, that is probably enough to prevent the repairman at your computer repair shop from reporting you to Homeland Security and may be enough to prevent recovery of images and files after you reformat your hard drive. (However, if it were my freedom at stake, I would give the drive the Lot’s wife treatment and buy a new drive.) Overall, I am fairly well convinced that XP is a defendable operating systems for mere mortals that follow a set routine and pay attention to security.

Since this belief is probably true, it leaves, Microsoft and the government out in the cold when you choose to observe their nefarious connections. No, you cannot stop unwanted predators from connecting to your machine and probing you but you can keep your machine clean enough that there is little there to find. Now with Vista, this is clearly not the case. There are back-ups of everything as the default and many are complaining that that use of Vista will be a one way ticket to jail or unemployment as your total computer use is an open book.

So what is the answer for Microsoft and the Government to threats from a protectable XP operating system? Simple, introduce an unavoidable SP3 service pack. I mean I avoided the upgrade for IE7 forever or at least until there were so many vulnerabilities that were left unplugged until I down loaded it even though I use Firefox. I suspect avoiding SP3 will eventually leave me so exposed that I will have to do it and ultimately upgrade myself to a system as unknown and undefendable as Vista. Once this happens I may as well switch to Vista.

Oh well, shit happens.

Resistance is Futile, Knowledge is Soporific!
