Using untrusted proxies can pose significant threats to your online freedom. A third-party proxy server reroutes your web requests through its server before connecting to the destination server, but when this proxy server is compromised, it can intercept and misuse your sensitive information.

Some of the most concerning security risks associated with using untrusted proxies include:

1. Unsecured Data Transmission: When you use a proxy server, your internet requests travel through the proxy before reaching the destination server. Unsecured proxies may not protect these requests, exposing your personal and financial data, such as credit card numbers. Hackers can intercept your data and exploit it for harmful purposes.
   
   
2. DNS Spoofing: A malicious proxy server can manipulate domain name system (DNS) queries, redirecting them to fake websites or servers controlled by the hacker. This allows the attacker to mobilize malware, confiscate sensitive information, or steal sensitive information from unsuspecting users.
   
   
3. Tampering with HTTP Cookies: Many websites use HTTP cookies to authenticate and identify users. An unsecured proxy server may be able to intercept and tamper with these cookies, which can result in identity fraud or unlawful access to personal information.
   
   
4. Man-in-the-Middle Attacks (MitM): In a classic MitM attack, an attacker intercepts and manipulates the communication between a user and a website or network. Proxy servers can facilitate these attacks by providing the attacker with an entry point to introduce malicious code or steal sensitive information.
   
   
5. Other Risks: Using untrusted proxies can also lead to bandwidth throttling of your browsing activities without your awareness.
   
   

To avoid these dangers, it is crucial to use trusted proxy servers or virtual private networks (VPNs) that utilize robust protection protocols. Always check the online reviews and ratings of a proxy provider before signing up, and be vigilant of proxies that are free or telegram下戴 guarantee unusually high bandwidths. If you're insecure about the security of a proxy, it's best to avoid using it altogether.
