The Essence of Technology

We often talk about bidding and we think of a single ad space. What do you think about multi-bids ? Is there a way to implement it today ? How can we improve things ? There is two issues here : one is multi-bids, the other is multi-tags. From the very beginning, we built AppNexus to support both multi-tags and mutli-bids. We always encouraged the industry to work this way. Even at Right Media, I was pushing at this internally. The reason why it is not doable yet is that it is complicated to implement and most actors have not put the effort to get to that level. What would be the advantage for the industry to implement it ? Quantity : every time you do not multi-bid, you are losing traffic. You are losing revenue. Inefficiency hurts everybody. Anything that make the system more efficient benefit to everyone. AppNexus has supported it for a long time but more people need to talk about it. How do you define AppNexus. Are you a DSP, a SSP, an adexchange ? It is hard to define f

1. Arachni Arachni is a feature-full, modular, high-performance Ruby framework aimed towards helping penetration testers and administrators evaluate the security of web applications. Arachni is smart, it trains itself by learning from the HTTP responses it receives during the audit process. Unlike other scanners, Arachni takes into account the dynamic nature of web applications and can detect changes caused while travelling through the paths of a web application’s cyclomatic complexity. This way attack/input vectors that would otherwise be undetectable by non-humans are seamlessly handled by Arachni. Finally, Arachni yields great performance due to its asynchronous HTTP model (courtesy of Typhoeus). Thus, you’ll only be limited by the responsiveness of the server under audit and your available bandwidth. Note: Despite the fact that Arachni is mostly targeted towards web application security, it can easily be used for general purpose scraping, data-mining, etc with

Sometimes even the most reputable PPC search engines face the problem of fraudulent clicks. They put quite an effort into protecting their clients from click scam. Take Google, for example. About a month ago it acquired spider.io with the aim of improving efficiency of Google advertising. Spider.io is a quite successful fraud- fighting company: last year it discovered Chameleon – the botnet that caused 6.2 million advertising dollars to be wasted on bot clicks. Monthly. Advertisers are the ones who suffer the most in this case. As networks get their profit even with malicious publisher websites, some of them don’t want to invest their time into fighting against click fraud. So how can you recognize the network that actually cares? There are a few features that distinguish a quality network. A reliable network would apply third party fraud protection solutions (or it has its own technology to fight invalid clicks), and it would implement techniques like IP filtering and URL blockin

An advertising analytics company said it has discovered a botnet that generates upwards of US$6 million per month by generating bogus clicks on display advertisements. Data integration is often underestimated and poorly implemented, taking time and resources. Yet it Spider.io, based in the U.K., wrote that the botnet code, called Chameleon, has infected about 120,000 residential computers in the U.S. and perpetrates click fraud on 202 websites that collectively deliver 14 billion ad impressions. Chameleon is responsible for 9 billion of those impressions, Spider.io said. Click fraud cheats Web advertisers by making them pay for clicks on ads that are not legitimate, depriving them of customers and revenue. Spider.io said advertisers pay an average of $0.69 per one thousand impressions. Spider.io did not identify the publishers of the websites that the botnet targets. But online media buyers have been noticing inconsistencies for some time on websites showing display ads for

This will send all traffic seen as a referral from example.com to a 403/forbidden page . If your concern is for your own website (most people reading this), then you’ll want to edit the main .htaccess for your site. This would be in your /home/username/public_html/ directory (some hosts rename public_html to httpdocs, www, web, etc..). You may want to block traffic from particular sites that link to your site. You can perform HTTP referrer-based blocking using mod_rewrite. Suppose you would like to block (with a 403 Forbidden code) traffic referred by badguys.com. Add the lines to .htaccess: RewriteEngine on RewriteCond %{HTTP_REFERER} ^http://(www\.)?badguys\.com [NC] RewriteRule (.*) - [F] You can block multiple domains using multiple RewriteCond lines and the [OR] flag, as follows: RewriteEngine on RewriteCond %{HTTP_REFERER} ^http://(www\.)?badguys\.com [NC,OR] RewriteCond %{HTTP_REFERER} ^http://(www\.)?badreferrers\.com [NC] RewriteRule (.*) - [F] NB: Be sure to add [OR]
