Ad formats & how they can be corrupted: #1 Popunders

In this three part series we look at popular ad formats that can be corrupted with Malware. In part one we look at Popunders.

What is a Popunder?

A Popunder is a large format full screen online advertisement. It is displayed by opening a new browser window after an interaction from the user with a website (e.g. click), usually via some sort of JavaScript. The new window opens behind the one that is currently being viewed by the user. It does not interrupt the user experience. When the user closes the page he is viewing, the Popunder remains for the user to see.

Why do cybercriminals target this format?

Because Popunders usually remain unnoticed until the active browser window is closed or minimized, the user may not notice the advertisement/malvertisement for a while. Usually an ad networks Compliance team’s approval process for Popunders is less strict than for other ad formats because ad networks offering this format tend to be more flexible, for example this format is not available on Google.

How do they do it?

The cybercriminal will submit a ‘clean’ Popunder to an ad network during the review process. Once approved the cybercriminal can then inject malware script into the Popunder. Many cybercriminals will inject the malicious code for a limited time to avoid detection of the Popunder’s content change.

What examples has AdSecure seen of malicious advertising using this format?

Our system has detected the following malicious advertising on Popunders:

  • Malicious/Phishing URLs
  • Malware downloads (including ransomware)
  • Crypto-jacking
  • Scareware
  • Browser Lockers

AdSecure’s advanced crawler technology can detect changes in a Popunder’s content that is injected with Malware. Contact us to find out how we can protect your users and keep your advertising safe.

The Importance Of a Secure Ad Platform

Online advertising is a booming industry with over 204 billion dollars spent on advertising worldwide in 2017. Countless websites use advertisements to pump up their earning power and recommend useful products and services to their visitors. But many website owners fail to consider the security of their ads, leaving consumers open to risk. Here’s what you need to know to keep your ad platform secure.

What is a Secure Ad Platform?

As a consumer, how many times have you been surfing the internet, reading a news article, or making a purchase when an ad blocks your view? Often, malware ads pop up and refuse to go away, forcing you to close your browser or app to get rid of them.

As Fast Company reported in early 2018, these malware ads negatively influence the consumer experience. In fact, even big-name websites like The New York Times and The Atlantic have fallen victim to malware ads that hinder users’ ability to read and interact with articles.

The bad news is, although these ads may appear to be publisher-run material, it’s difficult for sites to find the source and remove them. As top-tier publishers are finding out, a secure ad platform is crucial for both consumer trust and a dependable income stream.

Consider the fact that malicious auto-redirect ads have cost publishers and marketers over $1 billion, according to Fast Company’s expert. Smaller businesses stand to lose a proportionate amount of their income as well if malware continues to dominate the internet.

In contrast with the spammy pop-up ads that many users run into, a secure ad platform maintains only legitimate and scam-free advertisements. This protects your audience and your reputation as a business or website owner.

A secure platform can also notify website owners of potential problems. Scanners and subsequent reports inform you when ads and landing pages are out of compliance with your specifications so that you can avoid exploit-kit based and other attacks.

Even if you don’t have secure ad software to do the work for you, there are still steps you can to recognize and mitigate security risks.

Security Red Flags to Watch For

Filtering out legitimate versus malware ads without software involves thoroughly checking your website and files for signs of “infection.” From viruses to Trojan software, there’s a lot that can hide in advertisements.

Code Changes

On the back end of your website, keeping an eye out for unauthorized code changes can help you catch malware before it wreaks havoc. Often, spam ads “hack” into your website’s code and cause annoying and potentially viral popup ads.

Unfortunately, because these malware ads are attempting to go unnoticed, they can be hard to identify. However, some programs scan your code and automatically make backup files. You can do this manually, too, with a bit of general coding knowledge.

Sluggish Site Behavior

While you may be more concerned with what’s happening behind the scenes on your website, it helps to visit your website the way your audience does. This way, you can gauge your site’s loading speed. The longer it takes to load, the more likely there’s a problem with your ad platform.

Visiting your website from the front end will also show you any malware that’s currently active. If you experience popup ads when you load your site, you’ll know you need to take a closer look at the administrative end.

How to Stay Secure with Ads

While it can be hard to get rid of malware ads once they infiltrate your site, some simple preventative measures can help avoid them in the first place. Here are a few ways to stay secure with ads.

Use Secure Hosting

Depending on your business model, you may look for the least expensive hosting option available. But according to InfoWorld, hackers tend to target shared hosting servers. Because shared Web hosting servers host multiple domains, their information stores give hackers tons of information for phishing.

The alternative to shared server hosting is dedicated hosting, which often costs more but allows you more control over your server. You can also add extra security precautions that prevent hackers from readily accessing your information.

Run Malware Checks

Scanning your ad tags and landing pages for any issues can help identify malware before it takes over your website. You can also run checks from more than one browser, device, or location to ensure that everything is running smoothly.

Keep Things Simple

Overall, the more features on your website, the more likely you will fall victim to security breaches. That’s because complex code can hide malware codes more effectively, meaning you may not notice a website malfunction until a user reports it. At that point, you may have lost revenue already.

Trimming down the features on your website can help reduce your odds of falling victim to hacking, but that doesn’t mean you have to forgo interactive features that your customers will find useful.

AdSecure’s latest platform feature scans for Google compliance

AdSecure, the ad verification tool used by ad networks, ad operations teams and publishers, today announced that it has updated its scanning technology to recognise and flag advertisements that are not compliant with Google’s Abusive Experience Report. AdSecure’s latest platform feature uses state-of-the-art image recognition technology, machine learning and AI to recognise all ad formats and creatives that Google considers to be abusive and therefore non-compliant.  

According to Google’s Abusive Experience Report the following ads are specifically designed to mislead users and are therefore non-compliant:

  • Auto-redirect the page without action from the user.
  • Take the user to an ad landing page or other content when they click anywhere outside of the user-visible border of the element.
  • Resemble system or site warnings or error messages.
  • Simulate messages, dialog boxes or request notifications.
  • Depict features which do not work.
  • Display a “close” button that does anything other than closing the element when clicked.
  • Imitate Antivirus Alerts

Google states that from 15th February, publishers that feature any of the aforementioned abusive ad experiences will receive a violation notification. The publisher will have 30 days to stop displaying the non compliant ads and will have to submit their site for review via WebTools for approval from Google. For each listed experience, Google will provide a brief definition, the URL of the incriminated page, screenshots and a short video that shows the misleading element(s).

Once the publisher has fixed all the issues from the report, he will have to submit his website for review. Even though Google has not publicly shared an exact time frame on how long the review process would take, some sources seem to indicate that the review could take around two weeks. If the publisher fails to comply, external links (window.open/new tabs) will be blocked on the entire site which lead to a loss of ad revenue, including from Google Adwords.

Mathieu Derval, Product Manager at AdSecure commented, “We are excited to be adding new violations that Google considers as abusive to our detection arsenal. This new platform feature is a ‘must have’ for ad network platforms, publishers and ad operations teams. Not only does it ensure that publisher revenues are not compromised by penalisation from Google, but publishers continue to preserve trust and security within the online advertising ecosystem.”

Derval continued, “AdSecure clients have the capacity to run comprehensive scans to inspect their ad tags and will receive real-time notification alerts through AI assisted analysis, each alert features a comprehensive report listing the non-compliant elements, allowing clients to take immediate action and reduce the risk of their own publisher clients getting flagged by Google.”

3 reasons to use AdSecure’s new Residential IP scanning technology

The AdSecure engineering team has been very busy over the last few weeks, and we are very excited to announce a major product enhancement that will further improve the overall detection of malicious ads. The new feature offers clients the possibility of scanning tags and landing pages from Residential IPs.

Residential proxies are IP addresses from a standard Internet Service Provider (ISP), often DSL or cable, that are wired directly into a user’s home, unlike Datacenter proxies, which are IP addresses that come from a secondary corporation and work by hiding the users’ IP addresses from the internet.

AdSecure’s Residential IP features allows you to:

1-  Beat cloaking practices

Cloaking is a common technique used by bad actors to display different ads or landing pages to users than the ones that are approved by ad platforms. Because ad platforms usually use Datacenter and not rotating IPs, it is easy for a criminal to know which IP address the compliance team is using during the review process, so the bad actor fools them by serving a compliant ad, while serving a malicious version to the rest of visitors.

2- See what real users see

Now you can scan ads and landing pages that are the ones being seen by ‘real’ users so you can verify the integrity of each offer.

3- Safeguard Your Audience.

Protect your users and your reputation by stopping non-compliant ads and landing pages.

As of today AdSecure gives you access to Residential IP scanning for over 70 GEOs including: US, Canada, Germany, France, Mexico, Italy, Thailand, Brazil and many more. In the near future AdSecure be adding more Residential IPs.

AdSecure launches ad scanning for premium 3G mobile carrier IPs

Barcelona, 13 November 2017.  AdSecure, the ad verification tool used by ad networks, ad operations teams and publishers, today announced that it has significantly improved its mobile ad scanning technology by implementing 3G proxies across a range of countries and mobile carriers.  

This new platform feature allows clients to scan live campaigns that are targeting specific mobile users.  This is a highly powerful feature as advertisers tend to show different type of offers for 3G and Wifi users, and this can be challenging to monitor.  

The feature works by allowing clients to scan by country, 3G carrier network and iOS or Android.  Once a fraudulent, malicious, non-compliant campaign or landing page is detected the client is immediately emailed a comprehensive analysis of each anomaly detected, which leads to a better understanding of the ad’s redirection chain  so that they can take action.  AdSecure has deployed this feature in 16 countries, supporting over 50  mobile carriers. And planning to release new mobile carriers in the near future, to offer the widest range of 3G proxies in the market. Current locations include :

  • Austria: A1 / T-Mobile / Three
  • Belgium: Base / Orange / Proximus
  • Brazil : Claro /OI / TIM / Vivo
  • Canada: Bell / Rogers / Telus
  • France: Bouygues Telecom / Free / Orange / SFR
  • Germany: e-plus / O2 / T-mobile / Vodafone
  • India: Airtel / Vodafone / Idea / Aircel
  • Italy: Three / Tim / Vodafone / Wind
  • Mexico: AT&T / Movistar / Telcel
  • Netherlands: KPN / T-Mobile / Vodafone
  • Poland: Plus / T-Mobile
  • Portugal: Meo / Nos / Vodafone
  • Spain: Movistar / Orange / Vodafone / Yoigo
  • Switzerland: Orange / Sunrise / Swisscom
  • UK: EE / O2 / Three / Vodafone
  • USA: AT&T / Sprint / T-Mobile / Verizon

A full list can be viewed here.

Mat Derval, Product Manager at AdSecure commented, “AdSecure’s core mission is to protect the internet browsing experience and the addition of our new 3G feature allows clients to scan ad campaigns aimed at desktop and/or mobile 3G connections.  Now publishers and ad networks have the the tools to immediately identify fraudulent campaigns and ensure that their ad space inventory is filled with compliant, malware free ads to protect their users.  Additionally ad networks working with affiliates can now scan affiliate mobile offers and mobile carriers can scan ads that are using their 3G network.”

AdSecure will add more countries and mobile carriers very shortly.  For further information visit https://www.adsecure.com

Mathieu Derval, Product Manager at AdSecure comments,

“Malvertising poses a very serious threat for the online community and for the entire online advertising ecosystem. Malware distributed through the digital advertising supply chain degrades overall trust in this ecosystem. Cybercriminals are taking advantage of the open system which relies on multiple parties including advertisers, ad networks, ad exchanges and site publishers. The boom in programmatic advertising offers attackers advanced targeting options making their malicious campaigns extremely effective and difficult to detect. This is why we created the AdSecure platform to give the industry the most effective, accurate and reliable ad verification tool.”
