In July 2022, the story of 911.re – one of the largest low-cost proxy services with a controversial reputation – seemed to be over. It was suspected that the website had been compromised by several phishing attacks and permanently shut down.

However, the 911 service continued to run regardless of the attacks. This is extremely risky for newcomers, but for proxy enthusiasts, it is encouraging that mirror sites and clone apps still exist after the official closure.

What is 911.re?

In 2016, the 911.re website published the first downloadable 911 proxy software. The identity of the owners remains unknown. However, a 2019 study by the University of Sherbrooke found that the service is of Chinese origin and is associated with Grand Media Ltd. as well as International Media Ltd. companies.

The service offered a proxy network that provided private IPs around the world. The network claimed to have thousands of private IP addresses from 190 countries.

The average cost of a proxy package was quite low. In addition, the service offered unlimited lifetime access to a range of purchased proxy IP addresses. The most basic package of 150 proxies costs $28. This study examines whether such a low-cost strategy is feasible and whether it is worth pursuing.

What Is Residential Proxy Network?

What is a Proxy Connection

Proxy connection explained

A proxy connection allows a client to redirect its traffic through an intermediate proxy server. On the other hand, a proxy server acts as a gateway and protects the user’s endpoint from tracking, spyware, and other threats. In addition, the intermediary computer replaces the user’s original IP address with its own.

Most Internet users use proxy connections to protect their Internet browsing. Others use proxies only to hide their online activities and identities.

Residential and Datacenter Proxies

The most common proxy types are residential and data center proxies.

Residential and Datacenter proxies explained

  • Residential proxy servers are the physically existing nodes. They have their real IP addresses and their owners. These proxy connections look natural to the end servers. For this reason, private proxies are popular for web scraping, SEO research, web testing, etc.
  • Datacenter proxies are artificial and software-defined. They are faster than private proxies, but a data center proxy connection is easier to classify as suspicious and therefore more likely to be banned.

What are Residential IPs

Trusted residential IP providers use servers from trusted partners or users with their legal consent.

There are also open proxy networks such as Proxygate, where users voluntarily join the network and agree to work as nodes.

Some companies use adware and malware programs to infect a user’s machine and add it to the network as a node.

How does Proxy 911 Work?

911.proxy network
911.re network

Since the 911 tunnel proxy connection was cloaked, the 911.re proxy network used customers’ PCs as nodes without their knowledge. As a result, the service offers a huge pool of private IPs from all over the world. The bad news is that most of the network’s users didn’t know that they were part of a massive botnet. On the other side, the good news is that it still worked as a free VPN.

Even though the program was unreliable, vulnerable, and infested with adware, it fulfilled its task of hiding the client’s identity for a pittance. This is why the 911 proxy was so popular for accessing geographically restricted websites, performing repetitive transactions, and even committing illegal acts.

The Vulnerabilities of 911 Residential Network

Shady Connection Scheme

The first disadvantage of the 911 app is its connection method. When customers install the 911.re proxy app, they also download two free VPN programs: Mask VPN and Dew VPN. This malware installs a backdoor and establishes a node connected to the 911 backend services.

Thus, on the one hand, the network consists exclusively of natural IP addresses. This is very useful for many litigations that require frequent requests to a server.

Adware

The 911 Proxy VPN software is not the only partner application that the user receives when installing the app. The service’s revenue was tied to pay-per-install systems, so the app had many hidden installs.

Website Vulnerabilities

On July 28, 2022, the 911 re proxy website was compromised by several phishing attacks. As the message on the website stated, a group of hackers had created hundreds of domains similar to the original website and stolen users’ credentials.

The website was poorly designed from the start, including exploitable cookies and the ability to bypass authentication.

Why 911 was popular. Pros and Cons of Using 911 Proxy

It seemed that a vulnerable app could not gain popularity, but it did. Many users liked Proxy 911 despite the high risk.

Even now that the main site is closed, people use mirror sites and look for 911 proxy alternatives like 922 proxies or YiLu proxies. This short comparison shows why you should try the 911.re app.

Pros

  • Cheap access to a package of hundreds of proxies,
  • Advanced settings to configure a connection in detail,
  • Possibility to use with other anti-detect apps,
  • Reduced blocking possibility. IP addresses belong to real people, so every connection looks natural.

Cons

  • Extremely vulnerable,
  • You must be part of a proxy network.

Program

  1. 1. On the Program tab, select the applications you want to connect through a proxy. For example, you can use a proxy connection for your browser or social media apps.
Program tab
Program tab

It is very convenient to designate a group of apps to connect through a proxy, while the other apps connect with your IP.

  1. 2. Add the applications you want to work with through the proxy:
  • Drag the app icon to the list,
  • Click the plus sign at the bottom of the window.
  1. 3. Once you have added the apps to the list, run the app:
  • Double-click the app’s icon in the list,
  • Right-click the icon and select Run.

Proxy List

  1. 1. Go to the ProxyList tab to manage the proxy settings. A list of IP addresses will be displayed. You can use any of them as the midpoint of your proxy connection.

ProxyList tab
  1. 2. If you want to specify a server location or the Internet provider, use a filter below the tab menu. Filter IPs by country, state, or ISP.
  1. 3. Select a proxy from the list and connect to that proxy server:
  • Double-click on the selected proxy,
  • Right-click the proxy and select “Connect”.
  1. 4. Check if the connection is established. Your active proxy connection is displayed at the top of the app as proxy info in red.

You can also verify your connection by sending a “What’s my IP” request to Google.

Today List

TodayList tab
TodayList tab

TodayList is similar to the favorites list. It shows the IP addresses used in the last 24 hours. You will also see the Stop Proxy button there to stop all proxy connections.

User Agent

UserAgent tab
UserAgent tab

Each time a user sends a request to a server, the server knows the visitor’s operating system and browser version from the HTTP User-Agent Request header. The UA string example is as follows:

User-Agent: Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)

The 911 app not only allows masking the IP address but also hides the real request header. You can replace your real UA string with any option from the list.

Settings

Settings tab
Settings tab

The Settings tab is essential for fine-tuning your connection. Detailed setup is also important for the proper functioning of specialized software such as anti-detect browsers and bot apps. 911.re proxy works well in combination with other tools for masking Internet activity.

For example, you can use it with Lalicat to create multiple accounts or with an Undetectable browser to hide your identity. Software websites usually offer their own 911 s5 proxy guides for download with detailed explanations about the settings.

The most popular options you may want to change when setting up your connection:

  • Setting the proxy port,
  • Assign multiple ports to different browser profiles,
  • Manage the waiting time for proxy connections,
  • Enable automatic closing on proxy change.
