The U.S. Department of Justice (DOJ) today said they arrested the alleged operator of 911 S5, a ten-year-old online anonymity service that was powered by what the director of the FBI called “likely the world’s largest botnet ever.” The arrest coincided with the seizure of the 911 S5 website and supporting infrastructure, which the government says turned computers running various “free VPN” products into Internet traffic relays that facilitated billions of dollars in online fraud and cybercrime.

On May 24, authorities in Singapore arrested the alleged creator and operator of 911 S5, a 35-year-old Chinese national named YunHe Wang. In a statement on his arrest today, the DOJ said 911 S5 enabled cybercriminals to bypass financial fraud detection systems and steal billions of dollars from financial institutions, credit card issuers, and federal lending programs.
For example, the government estimates that 560,000 fraudulent unemployment insurance claims originated from compromised Internet addresses, resulting in a confirmed fraudulent loss exceeding $5.9 billion.
“Additionally, in evaluating suspected fraud loss to the Economic Injury Disaster Loan (EIDL) program, the United States estimates that more than 47,000 EIDL applications originated from IP addresses compromised by 911 S5,” the DOJ wrote. “Millions of dollars more were similarly identified by financial institutions in the United States as loss originating from IP addresses compromised by 911 S5.”
From 2015 to July 2022, 911 S5 sold access to hundreds of thousands of Microsoft Windows computers daily, as “proxies” that allowed customers to route their Internet traffic through PCs in virtually any country or city around the globe — but predominantly in the United States.
911 S5 built its proxy network mainly by offering “free” virtual private networking (VPN) services. 911’s VPN performed largely as advertised for the user — allowing them to surf the web anonymously — but it also quietly turned the user’s computer into a traffic relay for paying 911 S5 customers.
911 S5’s reliability and extremely low prices quickly made it one of the most popular services among denizens of the cybercrime underground, and the service became almost shorthand for connecting to that “last mile” of cybercrime. Namely, the ability to route one’s malicious traffic through a computer that is geographically close to the consumer whose stolen credit card is about to be used, or whose bank account is about to be emptied.

KrebsOnSecurity first identified Mr. Wang as the proprietor of the popular service in a deep dive on 911 S5 published in July 2022. That story showed that 911 S5 had a history of paying people to install its software by secretly bundling it with other software — including fake security updates for common programs like Flash Player, and “cracked” or pirated commercial software distributed on file-sharing networks.
Ten days later, 911 S5 closed up shop, claiming it had been hacked. But experts soon tracked the reemergence of the proxy network by another name: Cloud Router.
The announcement of Wang’s arrest came less than 24 hours after the U.S. Department of the Treasury sanctioned Wang and two associates, as well as several companies the men allegedly used to launder the nearly $100 million in proceeds from 911 S5 and Cloud Router customers.
Cloud Router’s homepage now features a notice saying the domain has been seized by the U.S. government. In addition, the DOJ says it worked with authorities in Singapore, Thailand and Germany to search residences tied to the defendant, and seized approximately $30 million in assets.
The Cloud Router homepage now features a seizure notice from the FBI in multiple languages.
Those assets included a 2022 Ferrari F8 Spider S-A, a BMW i8, a BMW X7 M50d, a Rolls Royce, more than a dozen domestic and international bank accounts, over two dozen cryptocurrency wallets, several luxury wristwatches, and 21 residential or investment properties.
The government says Wang is charged with conspiracy to commit computer fraud, substantive computer fraud, conspiracy to commit wire fraud, and conspiracy to commit money laundering. If convicted on all counts, he faces a maximum penalty of 65 years in prison.
Brett Leatherman, deputy assistant director of the FBI’s Cyber Division, said the DOJ is working with the Singaporean government on extraditing Wang to face charges in the United States.
Leatherman encouraged Internet users to visit a new FBI webpage that can help people determine whether their computers may be part of the 911 S5 botnet, which the government says spanned more than 19 million individual computers in at least 190 countries.
Leatherman said 911 S5 and Cloud Router used several “free VPN” brands to lure consumers into installing the proxy service, including MaskVPN, DewVPN, PaladinVPN, Proxygate, Shield VPN, and ShineVPN.
“American citizens who didn’t know that their IP space was being utilized to attack US businesses or defraud the U.S. government, they were unaware,” Leatherman said. “But these kind of operations breed that awareness.”
Have you ever been browsing online and clicked a link or search result that took you to a site that triggers a “your connection is not private” or “your connection is not secure” error code? If you’re not too interested in that particular result, you may simply move on to another result option. But if you’re tempted to visit the site anyway, you should be sure you understand what the warning means, what the risks are, and how to bypass the error if you need to.
A “your connection is not private” error means that your browser cannot determine with certainty that a website has safe encryption protocols in place to protect your device and data. You can bump into this error on any device connected to the internet — computer, smartphone, or tablet.
So, what exactly is going on when you see the “this connection is not private” error?
For starters, it’s important to know that seeing the error is just a warning, and it does not mean any of your private information is compromised. A “your connection is not private” error means the website you were trying to visit does not have an up-to-date SSL (secure sockets layer) security certificate.
Website owners must maintain the licensing regularly to ensure the site encryption capabilities are up to date. If the website’s SSL certificate is outdated, it means the site owners have not kept their encryption licensing current, but it doesn’t necessarily mean they are up to no good. Even major websites like LinkedIn have had momentary lapses that would throw the error. LinkedIn mistakenly let their subdomain SSL certificates lapse.
In late 2021, a significant provider of SSL certificates, Let’s Encrypt, went out of business. When their root domain officially lapsed, it created issues for many domain names and SSL certificates owned by legitimate companies. The privacy error created problems for unwitting businesses, as many of their website visitors were rightfully concerned about site security.
While it does not always mean a website is unsafe to browse, it should not be ignored. A secure internet connection is critical to protecting yourself online. Many nefarious websites are dangerous to visit, and this SSL certificate error will protect you from walking into them unaware.
SSL certification standards have helped make the web a safer place to transact. It helps ensure online activities like paying bills online, ordering products, connecting to online banking, or keeping your private email accounts safe and secure. Online security continues to improve with a new Transport Layer Security (TLS) standard, which promises to be the successor protocol to SSL.
So be careful whenever visiting sites that trigger the “connection is not private” error, as those sites can potentially make your personal data less secure and make your devices vulnerable to viruses and malware.
Note: The “your connection is not private” error is Google Chrome‘s phrasing. Microsoft Edge or Mozilla Firefox users will instead see a “your connection is not secure” error as the warning message.
If you feel confident that a website or page is safe, despite the warning from your web browser, there are a few things you can do to troubleshoot the error.
Remember, you are taking your chances anytime you ignore an error. As we mentioned, you could leave yourself vulnerable to hackers after your passwords, personal information, and other risks.
Your data and private information are valuable to hackers, so they will continue to find new ways to try and procure it. Here are some ways to protect yourself and your data when browsing online.
As we continue to do more critical business online, we must also do our best to address the risks of the internet’s many conveniences.
