In today's highly digitalized world, browsers are not only information portals, but also bear the privacy and security of users. Chrome extensions, as tools to improve efficiency, have frequently become targets of attacks due to abuse of permissions and malicious code implantation. In December 2024, the extension of a well-known data protection company was hacked, resulting in large-scale theft of users' Facebook advertising accounts, which once again sounded the alarm. In the face of such threats, traditional protection methods are no longer sufficient, and the innovative design of BitBrowser provides users with a more efficient solution.

 

 

Chrome extensions are essentially micro-programs that interact deeply with browsers through permission acquisition. However, excessive permission requests and exploitation vulnerabilities make them a breakthrough for hackers.

 

For example:

 

Abuse of permissions: Some extensions require access to "all website data" or "browsing history", far exceeding their functional requirements.

 

Malicious code injection: Hackers hijack developer accounts or exploit vulnerabilities to implant malicious scripts in updates, quietly stealing cookies, session information, and even injecting ransomware.

 

Hidden threats: infected extensions can still operate normally, and users are difficult to detect abnormalities, resulting in long-term data leakage or browser hijacking.

 

 

Conventional protection measures such as "download only from official stores" and "regularly update extensions" are effective, but have obvious shortcomings:

 

Passive permission control: users need to manually review the permission requests of each extension, which is easy to leave hidden dangers due to negligence.

 

Insufficient sandbox isolation: Although Chrome's default sandbox isolates web page processes, extensions can still obtain data across sites. Once breached, the scope of impact will expand.

 

Update lag risk: Vulnerability repair depends on the developer's response speed, and users passively wait for updates, exposing themselves to attack windows during this period.

 

 

In response to the above pain points, BitBrowser achieves active defense through technological innovation:

 

 

Each extension runs in an independent virtual environment, and data interaction must be strictly reviewed. Even if an extension uploaded by a user is breached, malicious code cannot penetrate the environment to steal data from other browser windows or other extensions, significantly reducing the risk of lateral spread.

 

 

All the extensions of BitBrowser are from the official real extensions, all use the latest official version, and the extensions that can be directly launched by BitBrowser have passed the official verification, without backdoor risk, and security is guaranteed.

 

 

Fingerprint Browser limits the access rights of extensions and only allows necessary functions (such as the extension management tool of BitBrowser).

 

User operation suggestions:

 

Combined with the functions of BitBrowser, users can further optimize the protection strategy:

 

Regularly clean up redundant extensions: uninstall plug-ins that have not been used for a long time to reduce the attack surface.

 

Enable "privacy mode": For sensitive operations (such as online banking login), use the isolated session function of BitBrowser to avoid cookie residue.

 

Integrate multi-layer protection: with proxy IP service, hide the real IP and prevent cross-site tracking.

 

 

The convenience of Chrome extensions coexists with risks, and BitBrowser redefines the browser security boundary. In the context of escalating network threats in 2025, choosing adaptive tools and developing good habits can achieve true "worry-free browsing".
