80M People Scammed by Chrome Fake Ad Blockers: the Same Old Song
Chrome Web Store is overflown with malicious browser extensions. Millions of people use them and don't even realize they are in danger. Why does it happen and how to fix it?
Fake Ad Blockers 2: Now with Cookies and Ad Fraud
Here is a story of how we (once again) found some fake ad blockers on Chrome Web Store — now with cookies and ad fraud.
$5 Billion Worth Man-Made Disasters Then and Now
Facebook's recent $5 billion fine marks a new era. Personal data has been made a commodity by corporations. But do people on the web mind it at all? AdGuard has conducted a survey among its website visitors to find the answers, and the results are quite interesting.
"Big Star Labs" spyware campaign affects over 11,000,000 people

In the previous article about the Unimania spyware campaign I promised to tell you more about the privacy issues discovered during our automated scan of many Google Chrome extensions. This took me a while, and I apologize for the delay.

Unimania: I Need Your Facebook Data, Location, And Your Browsing History

Privacy protection is basically what we do, so I never get tired of stories about how unpredictable the ways of getting Facebook user data are. Cambridge Analytica might be dead, but the business of stealing users’ data lives on, and this article demonstrates one more example of that.

Over 20,000,000 of Chrome Users are Victims of Fake Ad Blockers

According to the PageFair 2014 report, Google Chrome is a major driver of adblock growth. 20% of users discovered ad blocking by browsing “available browser extensions”. Given how popular ad blocking is, it is quite a lot. This also explains why "cloning" wide-spread ad blockers has become so popular among online crooks. Seven months ago big news broke: 37,000 users were tricked into installing a fake Adblock Plus extension.

What if I told you that thanks to poor Chrome's WebStore moderation the situation is much worse, and in reality over 20,000,000 users are affected and tricked into installing fake malicious ad blockers?

One does not simply delete Facebook

Calls to "delete Facebook" across different social media are growing in popularity. This is users’ reaction to recent publications in media about how a certain analytics company purchased personal data of 50 Million Facebook users from one of the app’s developer, and then proceeded to use this information to influence elections and political campaigns outcomes.

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.

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.
