AdGuard launches Nightly builds

We are very proud of our users, and especially of our beta testers. They are the most dedicated testers we know, but even among them there are those who stand out, those who always long for more beta versions to put their hands on :) Specifically for them we decided to introduce so-called "Nightly" builds for Windows and Android versions of AdGuard. In this article I will explain what are they and how to get them. »

Top Cryptojackers are video streaming websites, and they do not use CoinHive

Back in December 2017, we added a mechanism that allowed users to optionally report websites whenever a cryptojacking script is detected by AdGuard. It proved useful right away and allowed us to discover the largest known cryptojacking campaign, which was being run by some popular video streaming websites. Since then we have received more than a million user reports, and now it's time to analyze them.

Over the last two months, we received over 1.3 Million reports on more than 120 thousand websites. It's important to notice that sometimes cryptojacking was detected on some legitimate websites (Google, Youtube, Instagram, etc) and this is most likely caused by malicious browser extensions or malvertising.

However, 40% (over half a million) of the reports came from just 50 domains. Let's take a deeper look into what the top cryptojackers do. »

The Year 2017 in Ad Blocking

The year 2017 was a tough one for privacy protection and ad blocking apps, but a good one for their users. But any paradox seen here is illusory.

It was back in 2016 that the ad and marketing industries acknowledged the impending crisis. Ad-blocking growth statistics created great concern for many advertisers and publishers. Extrapolations showed that in a year or two almost nobody would see ads. Advertisers got ready to sell their lives at a high price. That was the year that ad reinsertion startup companies like PageFair, Admiral, Sourcepoint, Secret Media propagated, offering technologies to push ads through ad blockers.

It also was the year when the Coalition for Better Ads emerged.

Nowhere to run, nowhere to hide: cryptojacking now on Youtube

A video streaming service is a perfect place to launch a cryptojacking script. Users watch videos, and their computers are busy mining cryptocurrencies for the script’s owner. Youtube is a video platform with a huge audience, but unfortunately its owner Google is too selfish to let anyone run a mining script there.

But it lets people run ads inside Youtube videos! »

Browsers join ad blockers in the fight for safe and comfortable web — but are not ready to replace them

Good news from browsers keeps coming. Mozilla has recently added opt-in tracking protection in the new version of Firefox Quantum. Previously the protection worked only in the Private Browsing mode, now it can be turned on in settings and be active all the time. Besides privacy protection, the option provides faster web experience, it takes less time for web pages to load without trackers. »

Popular Android apps are stealing users' email addresses

Android is an awesome operating system that provides us developers with incredible capabilities. There are quite a few great apps and features Android users benefit from that are simply impossible to implement on other platforms.

Unfortunately, nothing comes free, and this wide array of capabilities is the main reason why Android is so vulnerable from privacy and security standpoints.

In our latest research, we decided to focus on the privacy issues. We took a look at the top 1000 Android apps to find out if they collect any sensitive personal data. »

AdGuard Browser extension v2.8 release

We are slowly getting back into the usual release rythm, and the honor of being the first AdGuard release of the year 2018 goes to Browser extension! The last bugfixes have been implemented and the new version has been uploaded to the stores.

Note: Safari store is traditionally on the slow side in terms of reviewing and approving extension updates, so it will take some time for the new version to get there. Other browsers' users can already download the fresh version. »
