27.06% of Scans Carried out by Adsecure in 2019 Detected Some Form of Malvertising

AdSecure, the innovative cybersecurity company that delivers ad security and ad quality solutions for ad platforms, publishers and app developers, today released its AdSecurity Violations Report for 2019.

AdSecure’s online security solution uses a crawler built around modern browser technology, that then analyses ad creatives and landing pages to detect malicious threats, non-compliance and ad quality issues in real-time throughout the advertising flow.

For this report AdSecure analysed more than 1 million ad campaigns across multiple regions, devices, and browsers for our partners between 1st January to 31st December 2019. These findings provide insights into cyber-criminal behaviour throughout the year: Where they were most prolific, how they delivered their attacks, their malicious weapons of choice, and what AdSecure’s detections revealed in order to stop and protect end users from malicious ads.

Countries with smaller online populations are exposed to more violations.

Of AdSecure’s top 10 GEOs for violations detected, AdSecure looked at the percentage of each country’s online population versus the percentage of violations. In the image below you can see that even though Israel has a 0.4% of the top 10 online population it received 7.6% of violation attacks, compared to say the USA with 14% of the top 10 population which received 21% of violation attacks.

The key takeaways

• Malvertising is a global challenge for publishers and their demand partners. While Tier 1 GEOs will always be a fruitful market for cyber criminals to launch attacks, they also routinely target developing markets that are experiencing growth. While the same  malicious ad may be running on opposite sides of the globe, it may only be active in one particular location at a given moment in time. Dedicated and routine monitoring for worldwide campaigns is key to detecting every threat, wherever they may be hiding.
• Auto-downloads & Auto-redirects are often the first step in the delivery of more severe attacks, such as malware or phishing threats, and as such should be taken seriously when in play. At the very least they are the cause of a poor user experience when visiting sites or using mobile apps. At worst the user becomes a victim of something far worse, and will likely never return to the site they blame for causing them harm.
• Dedication to frequently monitoring content is the best way for ad operations and compliance teams to ensure threats can be quickly detected and eliminated before they can harm users or damage revenue streams. The impact users have on the digital ads ecosystem is instrumental to its ongoing success. Platform and publisher sites have a duty of care to ensure that each user can engage with content safely, and always have an amazing experience when they do.
