How Talon’s Enterprise Browser Disarms Malicious Ads – Part 2

By Talon Research | October 26, 2023

In our previous blog post, we spotlighted the disturbing trend of malicious ads exploiting the Bing Chat feature. Recently, new details have emerged about a similar, and even more nefarious threat, so today, we’re delving deeper into a new wave of threats: malvertising campaigns that have set their sights on Google Ads. As the digital threat landscape shifts and grows, so does our commitment to safety. Talon’s Enterprise Browsing Platform is at the forefront, designed to navigate and protect amidst these evolving challenges.

What is Happening?

Recent reports from Malwarebytes have brought to light a cunning malvertising operation targeting Google Ads. This strategy specifically targets users searching for widely-used software, such as Notepad++ and PDF converters. But what makes this campaign stand out? Its intricate approach to user fingerprinting combined with the ability to distribute payloads that are both unique and time-sensitive.

When users search for these important software tools, they’re presented with fraudulent ads in Google’s search results. If clicked, these ads first screen the users, showing a decoy site to bots and other unintended IP addresses. However, when the visitor is identified as a valuable, human user to the threat actor, they’re redirected to a counterfeit website promoting the software. Behind the scenes, the user’s system is quietly fingerprinted to discern if the request comes from a genuine system or a virtual machine. Those who don’t fit the bill are redirected to the official Notepad++ website, whereas potential targets are tagged with a unique ID, making each malware download distinct and time-sensitive.

Homograph Attacks: Old Wine in a New Bottle

Another interesting aspect of this new malvertising campaign is the use of homograph attacks. While not entirely novel, their integration with deceptive Google Ads indicates that malvertising via search engines is advancing in complexity. By using Punycode to register domains that appear strikingly similar to legitimate sites, the objective is clear: to execute a homograph attack, deceiving users into downloading malware.

Cybersecurity experts have emphasized the enduring effectiveness of such techniques, especially in the realm of brand impersonation through malvertising. This, combined with other deceptive strategies like fake browser updates, highlights the importance of proactive defense mechanisms.

Talon Rises to Meet Modern Threats

Drawing parallels with the Bing Chat threat we dissected earlier, it becomes evident: the realm of cyber threats is not only intricate but also relentlessly evolving. However, where there are challenges, there are solutions. We’ve worked to develop the Talon Enterprise Browsing platform as not just a tool—but a new way to interact with the work environment as a whole. For both users and administrators, Talon provides a visible, flexible, and, most importantly, secure connection to the tools and resources they need to do their job.

Focusing specifically on this malvertising campaign, here are just a few of the protections, built-in to the Talon platform.

• Dynamic Fingerprint Detection: As cyber adversaries refine their fingerprinting tactics, Talon’s Enterprise Browser remains one step ahead. Our solution is geared to detect and nullify these fingerprinting attempts, creating a robust first line of defense against targeted malvertising endeavors.
