Embracing the Future: The Crucial Role of Artificial Intelligence in Browser Security Strategies

/in /by

We all have heard that traditional security measures are no longer sufficient in the ever-evolving landscape of cyber threats. Unfortunately, it’s often difficult to find a straightforward answer to how we address this.  As cybercriminals become more sophisticated, leveraging advanced technologies to bypass conventional defenses, it’s imperative for organizations and individuals to stay a step ahead. One of the most promising solutions to address this reality is Artificial Intelligence (AI) being a part of every aspect of an organization’s cybersecurity program. In browser security, the use of AI is not just beneficial but essential.  

The Rising Tide of Cyber Threats

While bringing unparalleled convenience and connectivity, the digital age has also opened the floodgates to a range of cyber threats on the internet. From basic phishing scams to advanced persistent threats, the risks associated with online browsing are increasing in complexity and frequency. The traditional, rule-based security systems are struggling to keep up, often reacting to threats rather than proactively preventing them.

The Artificial Intelligence Advantage in Browser Security

With its ability to learn and adapt, AI presents a game-changing solution in the realm of browser security. Unlike static security measures, AI-driven systems continuously evolve, learning from new threats and adapting their defenses accordingly. This proactive approach to security is crucial in a landscape where threats are constantly emerging and evolving.

  1. Predictive Risk Mitigation

AI systems can analyze vast amounts of data to identify potential threats before they materialize. By understanding patterns and anomalies in browsing behavior, AI can predict and mitigate risks, often before the user is even aware of them.

  1. Dynamic Threat Response

AI-driven browser security can respond dynamically to emerging threats. It can analyze the behavior of websites and scripts in real-time, detecting and preventing malicious activity instantly, ensuring real-time protection.

  1. Enhanced Accuracy and Efficiency

AI enhances the accuracy of threat detection with fewer false positives. This bolsters security and improves user experience by reducing unnecessary disruptions or isolations.  

Real-World Applications:Artificial Intelligence in Action

Imagine a scenario where your browser, protected by AI, identifies a phishing attempt before you click on a suspicious link, or a system that automatically isolates a potentially harmful download, analyzing it in a secure environment before it can do any harm. These are not futuristic fantasies but real applications of AI in browser security that are available today.

Artificial Intelligence as a Necessity, Not a Luxury

Incorporating AI into browser security strategies is no longer a luxury but a necessity. As we navigate the complex cyber landscape, the fusion of AI with traditional security measures will be vital to staying ahead of threats. It’s time for organizations and individuals to embrace AI as a critical component of their cybersecurity arsenal.

SHA-256: f3c75ad42c932bff7e498e90745f7a4b0d85da444f7fbfa3960e8ffbe41c6561

This URL was detected by ConcealBrowse on December 1st, 2023. The URL was first detected on August 26th, 2023, by 7 reputable security vendors. To date, 17 vendors have flagged the URL, further categorizing it as phishing, malicious, and malware. Using this information and real time analysis conducted by our Sherpa AI Engine, ConcealBrowse assigned a 29% risk score and isolated the URL 3 times in a row, combatting and protecting against end-user persistence.

Without ConcealBrowse, the end user would have introduced an HTML file to their endpoint, that subsequently reaches out to a “.cc” domain. This Australian domain, due to its cost effectiveness, is used by spammers and nefarious actors worldwide. It is hard to extrapolate the intent of the file, however, the action of introducing suspicious files to the endpoint raises concern. Additionally, the page is harvesting crypto wallet addresses to locate wallets, and potentially use the downloaded HTML file for follow on data exfiltration.

Browser-Based Threat Report

Week of November 27th, 2023

ConcealBrowse is leveraged by teams across the world to combat weaponized URLs. The technology is constantly analyzing suspicious web artifacts to identify risks in the form of drive-by attacks, phishing portals, and other threats that materialize while browsing.

At Conceal, your digital safety is our utmost priority. Our weekly threat report for the week of November 20th, 2023, unveils critical insights into the ever-evolving landscape of online threats.

The following report highlights recently detected sites that were deemed suspicious:

_____________

SHA-256: : f18313bd258045a0c134467990ca54423ad6c9427d57e921b9769bb4105a6e26

This URL was detected by ConcealBrowse first on November 15th, 2023 and continued to isolate on subsequent visits on November 16th and 21st. It was first identified by 3 security vendors on November 21st, 2023 and has since dropped to 2 vendors, showing remediation attempts by the domain owners. Due to this, the domain, which was sinkholed November 21st, has been removed from sinkhole rules by various DNS providers. This points out the dynamic nature of webpages and the threat domain, highlighting the importance of real-time analysis (provided by ConcealBrowse).

Upon historical analysis, the page was seen downloading a suspicious JavaScript file which was flagged by 2 vendors as suspicious. ConcealBrowse continues to intervene to date, isolating the page with a 14% risk score due to the history of the webpage and the abundance of empty and void links.

_____________

SHA-256: b5b3e43c5b74bdc9fc35fa3708a17a34394006d51b34c1efa21685be1629ede1

This URL was detected by ConcealBrowse on November 20th, 2023. The URL was first detected on November 27th, 2023, by 6 reputable security vendors. By analyzing sites in real time, ConcealBrowse protected the endpoint one week before intelligence sources could report its nefarious activity.

The URL leads victims to a malicious shopping page that is poorly designed. Indicators of nefarious activity include the irrational sizing chart when purchasing a vehicle, which further, was listed for sale at $14. Although it is apparent the site is suspicious, end users can initiate downloads with a simple click or even fall victim to drive-by download attacks that require no end user interaction. Supporting this is the fact that this page was shown to download an HTML file that was deemed suspicious by two additional security vendors. ConcealBrowse intervened additionally due to identified anomalies, such as the webpage’s malicious top-level domain.

_____________

SHA-256: 7122c4952c0e428874187a684e6cf72937fccf96033240a9077a6ed245da604b

After analyzing the URL in question, it was found to be flagged as malicious by several other threat intelligence feeds. The primary reason for their reporting this domain as malicious was due to it being associated with phishing/credential theft attacks.

Upon engaging the link, users are prompted with a captcha to verify they are human. Afterwards they are directed to a spoofed Microsoft login page.

Deeper analysis shows that this site, which is no longer live, was registered through Russia on August 30th of 2023 and was blocklisted by several providers due to its association with the Storm1575 threat group operating out of Russia. This group is known to use Dadsec, a phishing-as-a-service platform, with the goal of stealing Microsoft O365 credentials.

It is important to note that the site appears to have been taken down.

_____________

This URL was detected by ConcealBrowse during an INTERNAL TESTING session of our new SHERPA AI decision engine. The URL was brought to us by a customer who was concerned about this type of attack. The web page opens up and warns the visitor that their computer is infected and that they need to call Windows support. There is even an audible message warning the user to call immediately or risk serious damage. However, just like a BEC attack, there is nothing “malicious” tied to the webpage. The damage occurs when the victim calls the number and falls for the scam.

Since this is an attack that occurs in the browser, Conceal felt it necessary to detect and prevent these threats. With the new SHERPA AI engine, we are able to analyze a potential threat deeper than URL reputation and even deeper than patterns in how the web page behaves. We look at the patterns in the content of the website and what the intent of that content is. When we see an anomaly in the patterns in the behavior, patterns in the structure, or patterns in the content of a webpage, we treat it as suspicious and intervene to protect the end user. In the case of this webpage, there are several elements that a true warning from a reputable technology company such as Microsoft would never include. Based on this, our browser extension warned the end user of the dangers ahead, something that’ solutions relying on full-time browser isolation are not capable of doing.

ConcealBrowse Analysis: The Hidden Risks of Shared Hosting

/in /by

Introduction

In the intricate cybersecurity landscape, where threats evolve daily, tools like ConcealBrowse provide a much-needed safety net. A recent threat analysis for a hedge fund highlighted how ConcealBrowse’s smart decision engine leverages its “proximity” metric to identify potential threats, even when not directly implicated as malicious.

Decoding the Proximity Alert

In this instance, the URL in question was malaproject[.]com. At first glance, there seemed to be no direct evidence pointing to it being harmful. However, ConcealBrowse’s decision engine isolated the URL based on its proximity principle.

The Shared Hosting Concern

Further analysis revealed that malaproject[.]com was mapped to the IP address 192.232.223[.]30, registered with UnifiedLayer—a shared hosting service. Over the past two years, 22 URLs associated with the same IP address were flagged as malicious on various cyber threat intelligence feeds.

This discovery underscores a prevalent concern: websites hosted on shared services face increased risks. Shared hosting platforms might be cost-effective and resourceful for many, but they also become a hotbed for threats, as one compromised site can cast a shadow on others sharing the same IP.

ConcealBrowse: A Shield against Hidden Dangers

With shared hosting being a common choice for many online ventures, the risks associated with “bad neighbors” become more palpable. If a site on shared hosting is compromised, its neighboring sites become risky by association, given their proximity to the malicious infrastructure.

That’s where ConcealBrowse comes in. By detecting the elevated risk due to such associations, it ensures the site is isolated, preventing potential threats from causing harm. The “more work, less risk” mantra of ConcealBrowse captures its essence—it continually identifies and mitigates hidden dangers, allowing businesses to operate without disruption.

Conclusion

Shared hosting may be a double-edged sword, offering benefits but with hidden cybersecurity challenges. Tools like ConcealBrowse emphasize the importance of staying one step ahead, protecting organizations from not just direct threats but also from risks arising from their online environment. In an age of complex cyber threats, it’s no longer just about direct attacks but also about understanding the landscape and associations that might indirectly expose one to vulnerabilities. ConcealBrowse’s technology stands as a testament to the evolving nature of digital protection in today’s world.
