Free streaming boxes may be routing criminal traffic through your home

“Free” movies and TV could cost you your privacy, bandwidth, and control of your home network.

We’ve warned about illegal streaming and modded Amazon Fire TV Sticks in the past. Now, researchers have found that certain SuperBox devices and apps could quietly enroll a household connection into a proxy network, allowing third parties to route traffic through it.

An earlier report identified CyberFlix TV, available through SuperBox’s custom app store, as containing Popanet proxy functionality that registers the device with a server controlled by the proxy operator.

Law enforcement agencies have warned that “foreign entities” are using residential proxies to conceal their identities and make their activity appear to come from someone else’s home network.

The FBI defines a residential proxy as follows:

“A residential proxy is an intermediary server between individuals and websites they visit to make their connections appear to originate elsewhere. Legitimate IP addresses assigned by an Internet Service Provider (ISP) to consumers’ Internet of Things (IoT) devices, such as TV streaming devices, digital picture frames, smartphones, tablets, and routers are used to route traffic. Once an internet-connected device is compromised, the device’s IP address can be used by threat actors to mask their online illegal activity, making the consumer appear responsible.”

Residential proxy networks rent out ordinary home IP addresses to customers. That makes their traffic appear as if it originates from a legitimate consumer connection rather than a data center, helping cybercriminals evade IP-based fraud controls and reputation systems.

Besides affecting connectivity, this can mean that a household’s public IP address becomes associated with activity it did not initiate, ranging from credential stuffing and account abuse to attempts to bypass enterprise security controls.

Plume’s more recent research warns that these proxy networks can also function as malware-delivery platforms. In other words, attackers may not only use a compromised streaming box as an exit node. They may use the proxy connection to reach the box itself and install additional malicious software.

The reported SuperBox configuration is especially troubling because it disables or weakens multiple Android safeguards. Researchers found exposed Android Debug Bridge (ADB) access, root-level privileges without authentication, and the removal of protections that would normally restrict untrusted app installation or prompt users to approve risky actions.

Many people assume that placing a streaming device behind a home router prevents outside access. Normally, network address translation and a firewall do make unsolicited inbound connections more difficult. But proxy-enabled devices can maintain an encrypted outbound connection to a remote server, creating a channel that the home router treats as legitimate traffic initiated from inside the network.

How to stay safe

The safest option is not to connect devices or install apps that promise unauthorized access to free movies and TV. You could be bringing a proverbial Trojan horse into your home.

If you own a SuperBox device or have installed CyberFlix TV, disconnect the device from your network. A factory reset may not be enough to make it safe to use again, so you should replace it.

When a device’s business model depends on monetizing your connection, its security choices can put your IP address, bandwidth, privacy, and local network at risk.

Network segmentation can reduce exposure for ordinary Internet of Things (IoT) devices, but it is not a complete answer here. A product that intentionally establishes a persistent proxy channel and offers weak device-level protection should not be trusted on a household network, even on a separate guest network.

SonicWall Warns of Two Actively Exploited SMA1000 Zero-Days, One Rated Maximum Severity

Graphic showing SonicWall SMA1000 devices, CVE-2026-83548, the maximum-severity SonicWall SMA1000 pre-authentication vulnerability

SonicWall disclosed this week that attackers are chaining two previously unknown vulnerabilities in its SMA1000 secure access appliances to run commands on unpatched devices, and urged customers to install an emergency hotfix.

The more severe flaw, CVE-2026-83548, is a pre-authentication server-side request forgery weakness in the appliance's Appliance Work Place interface, rated 10.0 on the CVSS scale. It lets a remote attacker with no credentials reach sensitive internal functionality. The second, CVE-2026-83549, is an operating-system command injection bug in the Appliance Management Console rated 7.8; on its own it requires administrative authentication, but paired with the SSRF flaw it yields remote code execution.

The vendor said it found both issues internally and then observed them being used together in live attacks. SonicWall has not published indicators of compromise or described the attackers.

Affected products are the SMA1000 series 6210, 7210 and 8200v, in both hardware and virtual form. Fixed builds are 12.4.3-03526 and later, and 12.5.0-02952 and later. SonicWall firewalls running SSL-VPN and the separate SMA 100 line are not affected.

Remediation guidance goes beyond patching. SonicWall told customers to contact its support organization to review appliances for signs of intrusion and, where compromise is suspected, to re-image or redeploy the device, rotate all credentials and reset TOTP tokens — an acknowledgment that one-time-password seeds stored on a breached appliance survive a software update. The company said customers should move to the hotfix release as quickly as possible.

Shadowserver Foundation scanning has tracked more than 400 internet-exposed SMA1000 appliances, though an unknown share of those are already patched. The small install base belies the risk profile. These are remote-access gateways that sit at the network edge and hold credentials for the environments behind them.

The disclosure extends a difficult run for the product line. Attackers exploited a separate pair of SMA1000 zero-days in July 2026, tracked as CVE-2026-15409 and CVE-2026-15410, to deploy custom malware; CISA later confirmed ransomware operators were abusing that access.

Read: CISA Adds SonicWall SMA1000 Vulnerabilities to KEV Catalog Following Active Exploitation

Another zero-day surfaced in December 2025. Seventeen SonicWall vulnerabilities across the company's product families currently sit in CISA's Known Exploited Vulnerabilities catalog. Edge appliances from SonicWall, Ivanti, Citrix and Fortinet have collectively become the preferred initial-access route for ransomware affiliates and espionage crews, because they are internet-facing by design and rarely instrumented with endpoint detection.

DOJ Investigates Cyberattack Targeting Hundreds of Thousands of X Users

cyberattack on X users

A cyberattack on X users that targeted hundreds of thousands of accounts has prompted an investigation by the US Department of Justice (DOJ), with Attorney General Todd Blanche saying sophisticated cybercriminals attempted to exploit the platform's password-recovery system. The DOJ is working with Elon Musk's X, formerly known as Twitter, to identify those responsible for the attempted attack, according to Blanche's statement on Wednesday. The incident involved hundreds of thousands of X users and was disrupted before the targeted accounts could be captured, Blanche said.

Blanche Says DOJ Is Tracking Those Behind Cyberattack on X Users 

In a statement posted on X, Blanche described the incident as a password-recovery attack carried out by "sophisticated cyber criminals." He said X managed to disrupt the effort and prevent user accounts from being taken over.  Blanche wrote: 
This week, sophisticated cyber criminals attempted a password-recovery attack on hundreds of thousands of X users. X disrupted the attack to prevent user accounts from being captured. But, as we’ve shown, the Justice Department will stop at nothing in its pursuit of cyber fraudsters and scammers. We are working closely with @X to track down the criminals behind this week’s attack. There is no refuge for those that perpetrate their criminal schemes from behind computer screens." 
The attorney general did not disclose additional technical details about the cyberattack on X users, including how the attackers attempted to exploit the recovery system, whether any individual accounts were compromised, or where the suspected criminals were operating from.  The DOJ investigation is intended to identify those responsible for the attempted intrusion, with Blanche emphasizing that authorities would pursue individuals involved in cyber fraud and scams even when those activities are conducted remotely. 

How the Password-Recovery Attack Works 

A password-recovery attack generally targets the systems users rely on when they have forgotten their login credentials. These processes can include "forgot password" features, account-recovery forms, and other mechanisms designed to help legitimate users regain access to their accounts. Attackers may attempt to exploit weaknesses in those processes to obtain access to accounts. In the incident involving X, the platform was able to disrupt the effort before the targeted accounts were captured, according to Blanche. The scale of the attempted cyberattack on X users—hundreds of thousands of accounts—makes the incident notable, although the attorney general did not provide a breakdown of how many accounts were actually affected or whether any users suffered losses. 

AI-Driven Cyberattacks Add to Growing Security Concerns 

The X incident comes against a wider backdrop of increasing cybersecurity threats facing companies and organizations around the world.  Businesses have been dealing with a rise in AI-driven cyberattacks as well as ransomware campaigns capable of stealing sensitive information, interrupting operations, and creating significant financial and operational damage.  The growing use of artificial intelligence in cyber operations has raised concerns that attackers can automate or accelerate parts of their campaigns. At the same time, organizations are exploring ways to use AI-based systems to identify vulnerabilities and strengthen their defenses.  The DOJ has also been pursuing cases involving sophisticated cyber operations. Days before news of the cyberattack on X users, the department announced an operation targeting QTFY, described by US authorities as a Chinese cyberespionage platform. 

DOJ Previously Targeted QTFY Cyberespionage Platform 

According to the Justice Department, QTFY had targeted several US institutions and organizations. Those named by the department included the US Senate, the Federal Reserve, and NASA, among others.  The action against QTFY highlights the broader range of cyber threats confronting US institutions, from espionage operations to attacks aimed at obtaining access to online accounts.  The latest investigation involving X therefore comes amid a broader push by US authorities to identify and disrupt cyber criminals and state-linked cyber operations.

TerminalFix looks like ClickFix, but delivers a very different payload

Microsoft has published details about a Windows malware campaign it calls TerminalFix.

The social engineering used to infect people is very similar to what we’ve seen in ClickFix campaigns. A website visitor is presented with a fake Cloudflare CAPTCHA which, when clicked, secretly copies a malicious command to their clipboard.

Then they receive instructions on what they need to do to “prove they are human,” when in reality they are being instructed to execute the malicious command.

After gaining a foothold, the malware downloads what appear to be ordinary PNG images from attacker-controlled sites, but the images also contain concealed payload data. A PowerShell script reads the images’ pixel data: The first eight bytes specify the embedded file’s length, while the remaining data is reconstructed into an executable and two DLL fragments, which are joined on the victim’s disk.

The use of steganography is notable, but does not set TerminalFix apart from other ClickFix campaigns that have used the same method.

What does make TerminalFix different is its payload. One way or another, ClickFix victims usually end up with information-stealing malware of some sort.

TerminalFix instead chains together several mature evasion techniques, including DLL sideloading, steganographic delivery, folder hiding, realistic browser User-Agent rotation, and encrypted WebSocket traffic, rather than relying on one obfuscated PowerShell downloader. Its end goal is also different.

The campaign delivers a payload chain that performs domain-aware reconnaissance before installing a custom, multiplexed reverse TCP tunnel.

This hidden connection can give attackers access to the victim’s network. The infected computer first calls out to the attackers using encrypted web-like traffic over port 443, allowing the “reverse” connection to pass more easily through a company firewall.

In this way, the compromised system creates a secret remote-access doorway from inside the network. “Multiplexed” means the attackers can send several separate connections, for example to a file server, database, or another workstation, through that single encrypted tunnel at the same time. This allows them to use the victim’s computer as a stepping stone into the rest of the network.

How to stay safe

First, remember that a real CAPTCHA may ask you to click boxes or select images, but it will not ask you to open Run, Terminal, Command Prompt, or PowerShell and paste a command.

  • Slow down. Don’t rush to follow instructions on a webpage or prompt, especially if it asks you to run commands on your device or copy-paste code. Attackers rely on urgency to discourage careful thought, so be cautious of pages urging immediate action. Sophisticated ClickFix pages may add countdowns, user counters, or other pressure tactics to make you act quickly.
  • Avoid running commands or scripts from untrusted sources. Never run code or commands copied from websites, emails, or messages unless you trust the source and understand exactly what the command will do.
  • Verify instructions independently. If a website tells you to execute a command or perform a technical action, check through official documentation or contact support before proceeding.
  • Limit the use of copy and paste for commands. Manually typing commands instead of copy-pasting can reduce the risk of unknowingly running malicious payloads hidden in copied text.
  • Secure your devices. Use an up-to-date, real-time anti-malware solution with a web protection component.
  • Learn to recognize evolving attack techniques. Knowing that attackers continually change their methods can help you recognize suspicious instructions. Keep reading our blog!

Pro tip: Did you know that the free Malwarebytes Browser Guard extension warns you when a website tries to copy something to your clipboard?

Some browsers also restrict or warn about certain uses of the clipboard. Since macOS Tahoe 26.4, Terminal can warn users when they paste text copied from a browser or messaging app. This protection operates at the app and operating-system level rather than inside the browser.
