What can fingerprint be used for?

Digital fingerprints are actively exploited by cybercriminals as a means of circumventing modern anti-fraud solutions. These sophisticated tools enable fraudsters to take control of consumers' accounts, including those of online services and email providers, and carry out fraudulent transactions without being detected. Through manipulation of a victim's digital fingerprint, including IP address, browser information, device characteristics, screen resolution, time zone, language settings, and installed browser plugins, fraudsters can effectively spoof modern anti-fraud solutions and appear as legitimate users. This makes it exceedingly difficult to identify illicit activity, as these digital fingerprints closely resemble those of genuine users.

Websites that rely exclusively on a user's browser fingerprint to serve targeted ads could potentially allow remote attackers to manipulate their own fingerprint to match that of the victim for an extended period of time. This manipulation enables attackers to assume the identity of the victim and gain access to sensitive information about their personal life, preferences, and behavior, which can then be used for nefarious purposes such as scamming and identity theft.

In essence, the attacker can treat their browser as the victim's browser, receive the same or similar ads as the victim, and construct a profile of their illicit behavior. Moreover, attackers can infer other sensitive information about users, such as their age, health status, hobbies, and income levels. This information can be leveraged to create highly personalized scam schemes or other malicious activities that pose a significant threat to individual privacy and security.

In addition to perpetrating illegal activities related to payments, cybercriminals are also using these tools to exploit social media and email accounts. These activities are particularly challenging to identify, as popular fraud prevention solutions rely on aggregating data from various sources to verify user and device identities by scrutinizing large numbers of digital fingerprints extracted from consumer transactions and online activities.

What is anti fingerprint browser?

Fingerprinting technology has two distinct applications on the web. Advertisers use it as a mechanism to track individuals and gather their sensitive information, while anti-fraud teams like SEON leverage it as a vital tool to ensure network security by detecting fraudulent activities, even when fraudsters attempt to conceal their devices. However, with the constant evolution of fingerprinting technology, device fingerprinting solutions have become increasingly complex, prompting fraudsters and their suppliers to develop more sophisticated tools specifically designed to evade detection.

Referred to as anti-fingerprint browsers, these tools are specifically engineered to deceive device fingerprinting systems and replicate the online profiles of genuine users. While these tools may be marketed as safeguarding individuals' privacy and preventing tracking, their price points and technical requirements indicate that they are targeted towards distinct markets. Consequently, individuals who use these tools may not necessarily have good intentions.

In reality, these anti-fingerprint browsers are exclusively designed for device spoofing and can be utilized to acquire stolen credit card numbers or bank accounts and impersonate legitimate account owners. Additionally, these tools enable swift configuration switching to modify their online "appearance" every minute, thereby avoiding detection, and to test scalable optimal configurations, such as automated bot attacks and general bot detection. As a result, anti-fingerprinting browsers are a perilous tool that can be exploited for fraudulent activities instead of protecting individuals' privacy.

What is browser spoofing? How does it work?

Fraudsters resort to browser spoofing techniques to falsify their browser configuration, presenting a facade that they are utilizing a distinct browser than the one they normally employ. They achieve this by imitating users from different nations or locales.

This technique operates by manipulating HTTP header messages, enabling fraudsters to fabricate requests that seem to originate from a different browser. Websites may display differently depending on the browser used, rendering this technique effective in circumventing anti-fraud systems.

A significant benefit of this technique is that it does not necessitate the use of proxies or VPNs, which can arouse suspicion. Browser spoofing is frequently the preferred technique for fraudsters as it enables them to access multinational accounts and replicate vital elements like language, time zone, and other geolocation-based data for fraudulent purposes. Consequently, businesses and consumers must remain cautious of browser spoofing.

Fraudsters use this technique to circumvent fundamental security checks and fabricate browser profiles that are consistent with the victim's identity. Suppose they desire to utilize a US credit card to make a purchase. In that case, fraudsters can deceive their browser settings into coinciding with the language setting and time zone, tailor-made for their deceitful motives.

This duplicitous browser technique empowers fraudsters to effortlessly evade security checks and authentication without arousing suspicion.

How to realize browser spoofing?

1. Changing Browser Agent On Chrome

The user agent string (UA or UAS) is a crucial piece of information that a browser sends to a website in order to establish a connection. Despite differing in format and content depending on the browser, every request header must include a UA string for the server to authenticate and recognize the browser.

In essence, whenever you browse a website, the server checks your UA string to verify if your device can communicate with it. This process occurs automatically and yields valuable information, such as the type of browser, version, and operating system you are using. Therefore, modifying your user agent is a way to protect your privacy.

2. Dedicated browser for fingerprint spoofing

Nowadays, there are some browsers, such as the Lalicat anti-fingerprint browser, that allow users to modify their browser-based fingerprints. This browser uses virtualization to create different browser fingerprints, making it impossible for websites to track the real ones. The Lalicat anti-fingerprint browser achieves this by breaking down all the parameters that form the browser fingerprint and randomly combining them to form a new fingerprint each time a user visits a website, even if they are using the same device.

If you are someone involved in business operations, the Lalicat anti-fingerprint browser could be an ideal choice for you. In addition to protecting your privacy online, this browser also facilitates team use. The main account user can create multiple sub-accounts and manage them independently, thereby enhancing the team's productivity and reducing management costs.

With more and more websites relying on browser fingerprinting to collect user information, using the Lalicat anti-fingerprint browser is the best way to ensure that your online activities remain untracked and unmonitored. In addition, the browser can help you avoid the risks of personal information leakage and online scams, allowing you to browse the internet with greater confidence and freedom.
