Ad injection can originate from various sources like malicious browser extensions, malware and even through stored cross-site scripting (XSS).Īd injectors are often made by scammers who want to cash in on application downloads. What is Ad Injection?Īd injection is the process of inserting unauthorized advertisements into a publisher’s web page with the intention of enticing the user to click on them. The campaign was targeting users of some of the largest websites in the world through an extension available on both Chrome and Opera browsers called AllBlock. In this post, we’ll break down a new ad injection campaign that Imperva Research Labs recently uncovered. Imperva’s research team is constantly monitoring and researching client-side attacks to better understand the attacker’s TTPs (Tactics, techniques and procedures). And while the concept isn’t new ( Google stated it was the most common complaint amongst Chrome users back in 2015), just like with other online threats, bad actors are constantly refining their techniques. While you’re here, if an ad blocker sounds right for you, consider these other web browser extensions and features that make browsing the web safer and more private.Deceptive ad injection is a growing concern on the internet today, affecting many people browsing the web. Ads are still an important part of what keeps the internet largely free and accessible, including TechCrunch, even as subscriptions and paywalls are increasingly becoming the norm. Of course, you can switch your ad blocker off any time you want, and even allow or deny ads for entire websites. You can also get content blockers for Android and iOS, which block ads from loading on your device. If you’re looking for a widely recommended ad blocker, uBlock Origin is a simple, low-memory ad blocker that works for most browsers, like Google Chrome, Mozilla Firefox, Microsoft Edge and Opera, plus the extension is open source so anyone can look at the code and make sure it’s safe to run. The good news is that some of the best ad blockers out there are free, and can be installed and largely forgotten. That means the ad companies, like Google and Facebook, cannot track you as you browse the web, or learn which websites you visit, or infer what things you might be interested in based on your web history. Ad blockers are also good for privacy, because they prevent the tracking code within ads from loading. By blocking ads, would-be victims are not shown any ads at all, making it easier to find and access the websites of legitimate brands.Īd blockers don’t just remove the enormous bloat from websites, like auto-playing video and splashy ads that take up half the page, which make your computer fans run like jet engines. ![]() One of the FBI’s recommendations for consumers is to install an ad blocker.Īs the name suggests, ad blockers are web browser extensions that broadly block online ads from loading in your browser, including in search results. Malicious ads are also used to trick victims into installing malware disguised as genuine apps, which can steal passwords and deploy file-encrypting ransomware. Ads are often placed at the top of search results but with “minimum distinction” between the ads and the search results, the feds say, which can look identical to the brands that the cybercriminals are impersonating. In a pre-holiday public service announcement, the FBI said that cybercriminals are buying ads to impersonate legitimate brands, like cryptocurrency exchanges. That’s the takeaway message from an unlikely source - the FBI - which this week issued an alert warning that cybercriminals are using online ads in search results with the ultimate goal of stealing or extorting money from victims. ![]() This holiday season, consider giving the gift of security with an ad blocker.
