Netgear WG302 Firmware upgrade via Telnet

Posted by admin in Untagged 

http://kb.netgear.com/app/answers/detail/a_id/728

 NOTE: Instead of using SolarWinds TFTP server i used  TFTPd32(http://tftpd32.jounin.net/)

Part 1: Upgrade the Boot Loader Commands:

1. Connect to the WG302 console port via MS Hyper terminal with these settings:
  • Bits per second: 9600
  • Data bits: 8
  • Parity: None
  • Stop bits: 1
  • Flow control: None

2. Copy patch.txt from the zip file into a working file folder on your PC.
3. Connect the access point to your PC’s communication port with an RS232 cable.
4. After powering on the access point, immediately press CTRL-C (CTRL and C keys at the same time). The RedBoot> prompt displays in HyperTerm. Here's an example of what this sequence might look like:
+Ethernet eth0: MAC address 00:09:5b:74:f3:c5
IP: 192.168.0.35/255.255.255.0, Gateway: 0.0.0.0

Default server: 192.168.0.36, DNS server IP: 0.0.0.0
RedBoot(tm) bootstrap and debug environment [ROM]
Red Hat certified release, version 1.92 - built 18:59:19, Sep 19 2003
Platform: IXDP425 Development Platform (XScale)
Copyright (C) 2000, 2001, 2002, Red Hat, Inc.
RAM: 0x00000000-0x10000000, 0x0001f920-0x0ffd1000 available
FLASH: 0x50000000 - 0x50800000, 64 blocks of 0x00020000 bytes each.
== Executing boot script in 2.000 seconds - enter ^C to abort
^C
RedBoot>
5. Select Send Text File from Transfer Menu in HyperTerminal, and select patch.txt to transfer. The access point automatically rebots after upgrade is done.
6. Continue to Part 2 to upgrade the firmware.

Part 2: To Upgrade the Firmware Using TFTP

1. Configure the IP address of your PC to 192.168.0.36. 2. If you do not have a TFTP server on your PC, install one now. (These are available, free, from such places as Solarwinds. You may download the software from http://support.solarwinds.net/updates/New-customerFree.) 3. Copy the WG302 firmware image: wg302_v4_1_8.rmt into the TFTP Root directory, such as c:TFTP-Root. 4. Rename the image to wg302.rmt. (If your TFTP server gives an error "ixp425.rmt not found" then you have a beta unit. For beta units rename "wg302.rmt" to ixp425.rmt.) 5. Connect your PC and the WG302 access point directly with a CAT5 Ethernet cable. 6. Start the TFTP server. (An example, showing Solarwinds start-up window, appears below.)

7. Disconnect the power cord from access point.
8. Press and hold the reset button on access point. Plug in the power while holding the reset button.

Coffee fights Cavity!

Posted by admin in Untagged 

Well i never had 1 single cavity in my life. I guess i know now... 

 

Trigonelline 

Chemically, it's a molecule of niacin with a methyl group attached. It breaks down into pyridines, which give coffee its sweet, earthy taste and also prevent the tooth-eating bacterium Streptococcus mutans from attaching to your teeth. Coffee fights the Cavity Creeps

Five ways banks rip YOU off!

Posted by admin in Untagged 

Careless consumers share the blame for forking over $24 billion to banks in overdraft fees last year, but, as the NY Times points out, bank policies encourage these penalties.

 

(If you have over drafted with Wachovia/Wells Fargo, call customer service and ask them to waive your fees.)

 

Since 45% of U.S. banks rely on these funds to stay profitable, it's little surprise that they rig their banking practices to maximize the amount of overdrafts incurred.

 

Here are five rip-off techniques:

 

  1. Rearranging transactions. Let's say you have $100 in your account, and you make five debit card purchases, in this order: $1, $1, $1, $1 and $99. Instead of processing these transactions in the order in which they were made, the bank will process the largest first. In this example, that means you would be hit with three overdraft penalties instead of one.
  2. Depositing slowly, charging quickly. If your account is low on funds, banks are more likely to delay processing your deposits. Further, banks willprocess purchases faster if it will result in an overdraft penalty.
  3. Charging additional fees. At some banks, if you don't pay the overdraft fees within a certain time frame, they will tack on additional fees.
  4. Allowing debit card purchases. Banks allow customers to make purchases on debit cards with insufficient funds, instead of denying the transaction or notifying the buyer before finalizing the order.
  5. Not instituting maximums. Few banks will limit the amount of fees you can be charged in a single day. If you don't realize you've overdrawn, it can quickly snowball - especially if you make several purchases (even of a few dollars) during one day. To boot, many of the penalty ceilings don't kick in until you've already lost hundreds of dollars.

Fake Antivirus. They are taking over!

Posted by admin in malwarebytes , fake antivirus

Is funny how i was just writing a report on this same topic on Fake Antivirus.   Check out this article via Slahdot.org

http://it.slashdot.org/story/09/10/01/1524258/Fake-Antivirus-Overwhelming-Scanners

 Fake antivirus programs are multiplying at such a rate they could start to overwhelm the detection capabilities of signature-based scanners, the latest figures from the Anti-Phishing Working Group (APWG) have hinted.

Rogue or bogus programs passing themselves off as real antivirus software have been one of the malware themes of 2009, but the APWG's numbers for the first half of the year show that the organisation's members detected 485,000 samples, more than five times the total for the whole of 2008.

The reason for the growth in numbers is what is known in technical terminology as ‘polymorphism', an old defence technique which involves changing the binary checksum of every copy (or download) of a piece of malware. This makes it much more difficult for antivirus programs to detect the programs.

"The primary reason for the creation of so many variants is to avoid signature-based detection by legitimate antivirus programs," says PandaLabs' director and APWG member, Luis Corrons in the report. "The use of behavioural analysis is of limited use in this type of malware because the programs themselves do not act maliciously on computers, other than displaying false information."

The figures themselves are the good news because each statistic is, by definition, a detected sample. But these are likely to be only a percentage of the true picture. Fake antivirus software can be hard to catch using heuristics because they are often willingly installed by users who think the programs to be genuine, bypassing systems such as Vista's User Account Control (UAC)

How Online Tracking Companies Know Most of What You Do Online (and What Social Networks Are Doing to Help Them)

Technical Analysis by Peter Eckersley

This post is Part 2 of a series on user tracking on the web today. You can read Part 1 here.

3rd party advertising and tracking firms are ubiquitous on the modern web. When you visit a webpage, there's a good chance that it contains tiny images or invisible JavaScript that exists for the sole purpose of tracking and recording your browsing habits. This sort of tracking is performed by many dozens of different firms. In this post, we're going to look at how this tracking occurs, and how it is being combined with data from accounts on social networking sites to build extensive, identified profiles of your online activity.

How 3rd parties get to see what you do on the web.

Let's start with an example of 3rd party tracking: when we went to CareerBuilder.com, which is the largest online jobs site in the United States, and searched for a job, CareerBuilder included JavaScript code from 10 (!) different tracking domains: Rubicon Project, AdSonar, Advertising.com, Tacoda.net (all three are divisions of AOL advertising), Quantcast, Pulse 360, Undertone, AdBureau (part of Microsoft Advertising), Traffic Marketplace, and DoubleClick (which is owned by Google). On other visits we've also seen CareerBuilder include tracking scripts and non-JavaScript web bugs from several other domains. There are pretty sound reasons to hope that when you search for a job online, that fact isn't broadcast to dozens of companies you've never heard of — but that's precisely what's happening here.

Ten 3rd party tracking sites' content is included in CareerBuilder search results
(in this screenshot, NoScript is being used to identify the third parties whose code is embedded in the page)

Each of these tracking companies can track you over multiple different websites, effectively following you as you browse the web. They use either cookies, or hard-to-delete "super cookies", or other means, to link their records of each new page they see you visit to their records of all the pages you've visited in the previous minutes, months and years. The widespread presence of 3rd party web bugs and tracking scripts on a large proportion of the sites on the Web means that these companies can build up a long term profile of most of the things we do with our web browsers.

 

They can track us, but do they know who we are?

Given how much tracking firms know about our browsing history, it's worth asking whether these companies also know who we are. The answer, unfortunately, appears to be "yes", at least for those of us who use social networking sites.

A recent research paper by Balachander Krishnamurthy and Craig Wills shows that social networking sites like Facebook, LinkedIn and MySpace are giving the hungry cloud of tracking companies an easy way to add your name, lists of friends, and other profile information to the records they already keep on you.

The main theme of the paper is that when you log in to a social networking site, the social network includes advertising and tracking code in such a way that the 3rd party can see which account on the social network is yours. They can then just go to your profile page, record its contents, and add them to their file. Of the 12 social networks surveyed in the paper, only one (Orkut) didn't leak any personally identifying information to 3rd parties.

There are some interesting technical details in how the social networking sites leak this data. In some cases, the leakage may be unintentional, but in others, there is clever and surreptitious anti-privacy engineering at work.

Paths for Data Leakage from Social Networks to 3rd party Tracking Firms

The most obvious way that a 3rd party tracker might learn which account on a social networking site is yours is via the HTTP Referrer header. A typical URL on a social networking site includes a username or user ID number, and any 3rd party will be able to see that.1

A second and slightly more revealing method that some social networks use to leak personal information is through URL/URI parameters for the 3rd party content. One example from the paper is LiveJournal handing a user's gender, age, country and language to an advertiser:

GET /track/?...&fb_sig_time=1236041837.3573&
fb_sig_user=123456789&...
Host: adtracker.socialmedia.com
Referer: http://apps.facebook.com/kick_ass/...
(In this example, a Facebook app is sending the user's facebook user ID and signin time to to adtracker.socialmedia.com)

The third and most surprising method for leaking personal information is to alias 3rd party tracking servers into the host site's domain name in such a way that the 3rd party can see the host site's cookies, in violation of the same origin policy. Here's an examples:

GET /st?ad_type=iframe&age=29&gender=M&e=&zip=11301&...
Host: ad.hi5.com
Referer: http://www.hi5.com/friend/profile/displaySameProfile.do?userid=123456789
Cookie: LoginInfo=M_AD_MI_MS|US_0_11301; Userid=123456789;Email=jdoe@email.com;
(ad.hi5.com is actually ad.yieldmanager.com, and it's receiving different bits of personal information via both the URL and the hi5.com cookie which the same origin policy wouldn't have allowed it to have)

What can I do to protect myself?

Unfortunately, there is no easy way to use modern, cookie- and JavaScript-dependent websites and social networking sites and avoid tracking at the same time. In order to be substantially protected against these tracking mechanisms, you'd need to do the following:

 

  1. Pick a good cookie policy for your browser, like "only keep cookies until I close my browser", or manual approval of all cookies.
  2. Disable Flash Cookies and all the other kinds of "super cookies". You can test for these here.
  3. Use the Firefox extensions RequestPolicy and NoScript to control when 3rd party sites can include content in your pages or run code in your browser, respectively. These tools are very effective, but be aware that they're hard to use: lots of sites that depend on JavaScript will need to be whitelisted before they work correctly.
  4. Use the Targeted Advertising Cookie Opt-Out plugin. This will automatically opt you out of any 3rd party trackers who have an opt out somewhere that requires you to accept a cookie. Be aware that not all 3rd parties will offer opt outs, or that some of them may interpret "opt out" to mean "do not show me targeted ads", rather than "do not track my behavior online".
  5. As always, it doesn't hurt to use Tor via TorButton to hide your IP address and other browser characteristics when you want maximal browser privacy.

Unfortunately, many of the steps above are quite difficult to follow, and we're fearful that the vast majority of Internet users will continue to be tracked by dozens of companies — companies they've never heard of, companies they have no relationship with, companies they would never choose to trust with their most private thoughts and reading habits.

It isn't going to be easy to fix this mess. On the technical side, all of this tracking follows from the design of the Web as an interactive hypertext system, combined with the fact that so many websites are willing to assist advertisers in tracking their visitors. Browsers could be altered to make them harder to track, but great care and clever design will be required to achieve that without undermining the virtues of interactive hypertext in the first place. It's not clear that anyone has found the right way to do that yet.

On the legal side, it's clear that the current U.S. privacy regime isn't working: behavioral tracking companies can put whatever they want in the fine print of their privacy policies, and few of the visitors to CareerBuilder or any other website will ever realize that the trackers are there, let alone read their policies. It's time we found legal rules to ensure that people actually know when their privacy is part of the price they pay to visit a site.

  1. 1. One subtlety here is that sometimes the 3rd party won't be able to tell whether a profile is yours or belongs to someone else. But there are several ways around that: they can look for URLs associated with profile editing or other activites that your friends can't do with to your profile; they can see which profile you visit first when you log in to the site, and they can see which profile you visit most often over time.
