 ok. HTML is returned and only contains an obfuscated JavaScript. The obfuscated JavaScript makes use of eval and unescape with a payload of URL characters.
Obfuscated JavaScript is commonly used to hide redirection to the search engine spiders. This JavaScript manipulates the DOM to retrieve the referer and the keyword from the URL. It then uses these values in another redirection.
The response is 200 OK. HTML is returned with a JavaScript using top.location.href to redirect to the spam site.
So every purchase made at the site will be associated with the affiliate account 552.
The response is 200 OK. An HTML page is returned. This is the backdoor page. This contains a JavaScript which is used for the redirection and a web page with some content.
The web page contains some text like the following. This is rendered if JavaScript is disabled.
This is an example of language mutation with Markov chain filter applied. This is used to get the page indexed by the search engines and to properly distribute the keyword into the page. This avoids the ban of the search engines in case of keyword stuffing.
The JavaScript is hosted on the site itself. Web spammers approach students as they can be easily corrupted to host spam scripts. In this case, the JavaScript makes use of an array, str.lenght and String.fromCharCode to generate the redirection.
The response is a 302 Temporary redirection to the spam site.
The response is 200 OK. HTML is returned with the content of the pharmacy site.
The web app performs a 302 temporary redirection before loading the Account personal page.
This site is defined as scraped content site. This means that this site is automatically generated for the keyword passed through the ‘q’ parameter. It pulls then content from third party resources. In this case, curl php would be used.
Orange: Content generated automatically and containing links to spam sites. This page pretends to be a search engine. The URL reported in the site are fake.
Other 2 redirections from the same host and page klik.php but with different encoded string.
The response is 302 temporary redirection.
But how this is possible?
The JavaScript also checks if the referer is from SERPS. If JavaScript is not enabled or any of these conditions are not satisfied, then the user will be returned with the main page of the site.
This is an extract of the JavaScript on the main page.
document.URL.indexOf("?certified=")!=-1 || document.URL.indexOf("?discount=")!=-1 || document.URL.indexOf("?fda-approved=")!=-1) && ((q=r.indexOf("?"+t+"="))!=-1||(q=r.indexOf("&"+t+"="))!=-1)){window.location="http://sevensearch.net/delta/search.php?
The response is 200 OK. The HTML is returned with a scraped content site. From here, the scenario is similar to the previous case study. The link then redirects to an online pharmacy site with another GET request that tracks the affiliate.
By comparing the actual page and the cached one, it is possible to understand the attack. The cached page is full of generated text, users comments and links to the sevensearch.net scraped content site.
Web application vulnerabilities can be used for other purposes as well: SPAM for instance!
Cross Site Scripting, 302 redirection and web app vulnerabilities in famous blog software can be used for this purpose.
Therefore our risk perception needs to include threats related to web spamming as well. In simple words: if your site has a good PR and it is vulnerable, it becomes a potential candidate for web spamming.
Subscribe site to Google Webmaster Tool and Yahoo Site Explorer and periodically check incoming and outcoming links.
Set Google Alert on the site – this will notify if there are any changes related to the site on the SERPS.
Periodically check web server directory and source code of the web application for any presence of backdoor.

« Crafting with Mom!
It was a great message, but for much of it, I felt like it wasn’t relevant to me. I’m not employed*.  I don’t have an employer. So I listened, but didn’t really notice much application.
Until I thought about my “job”. I do have a job… to love, encourage, inspire and grow my children. I get to do it full-time and not juggle another job. And when I thought about my job, I realized… God has called me to this position, this “full-time job”. He is my employer. And WHAM… the whole message was suddenly very much directed at me.
I’m not going to do it justice in my summary, I’m sure. But Pastor Chris spoke of attitudes at work, gossip, “stealing” including time, obedience but especially obedience with the right attitude. And when I thought of my “job” as a full-time mom and these things, I realized that often I haven’t lived out these verses in serving God as my master (employer). I haven’t always had a good attitude, I’ve wasted my time in countless ways, I’ve grumbled about many of the “hours” I work.
 God’s allowing me to serve him full-time in the “job” a mother’s heart is created to do. I have amazing children who I get to help “grow in stature and favor with God and with man” (Luke 2:52). There are a million things vying for my attention, but I need to keep my Employer and the job He’s called me to at the forefront of my mind.

CALL THE 'ERADICO PROFESSIONALS!what should I put on my BS Bingo card?

Every year during out PD days, I make a bingo card with phrases I expect to hear, either things that are every year repeats, or the "hot new trends".  It helps keep me focused on otherwise insufferable content as I try to get a bingo or blackout.  So, what are some terms and phrases you think I should add?  (BTW, shouting "Bingo!" In the middle of PD, although cathartic, is not recommended.  Proceed at your own risk.\section{Introduction}
\subsection{Motivation and main results}
The analysis of critical points of conformal invariant lagrangians has drawn much attention since 1950, due to their important applications in physics and geometry. One of the prominent examples is harmonic maps $\u:\Omega\to \mathbb{S}^n$, which are critical points of the Dirichlet energy
\begin{align}
    \mathcal{E}(\u)=\int_{\Omega}|\nabla \u|^2dx.
\end{align}
When the domain $\Omega$ is a subset of $\R^2$, $\mathcal{E}(\u)$ is conformally invariant and this plays a crucial role in the regularity theory of such maps (see \citet{helein1990regularite}, \citet{riviere2007conservation} and references therein). The theory has been generalized to even-dimensional domains whose critical are called poly-harmonic maps.


In the recent years, many authors are interested in the analog of Dirichlet energy in odd-dimensional
cases, for instance, \citet{DaLio2013,da2015compactness}, \citet{DaLioRiv2011-1,DaLioRiv2011-2}, \citet{millot2015fractional},
\citet{schikorra2012regularity} and the references therein. In these works, a special but quite interesting case is the so-called half-harmonic maps from $\R$ into $\S$ which can be defined as critical points of the following line energy
\begin{align}\label{intro:E(u)}
    \mathcal{E}(\u)=\frac{1}{2\pi}\int_{\R}|(-\Delta_{\R})^{\frac14}\u|^2dx.
\end{align}
