Cybersecurity researchers have taken a close look at the inner workings of the Predator spyware, developed by the Cyprus-based company Intellexa. Rather than focusing on how the spyware initially infects a device, this latest research zooms in on how the malware behaves once a device has already been compromised.

The most fascinating discovery involves the mechanisms the Trojan uses to hide iOS camera and microphone indicators. By doing so, it can covertly spy on the infected user. In today’s post, we break down what Predator spyware actually is, how the iOS indicator system is designed to work, and how this malware manages to disable these indicators.

What Predator is, how it works, and what… Alien has to do with it

We previously took a deep dive into the most notorious commercial spyware out there in a dedicated feature — where we discussed the star of today’s post, Predator, among the others. You can check out that earlier post for a detailed review of this spyware, but for now, here’s a quick refresher on the essentials.

Predator was originally developed by a North Macedonian company named Cytrox. It was later acquired by the aforementioned Intellexa, a Cyprus-registered firm owned by a former Israeli intelligence officer — a truly international spy games collaboration.

Strictly speaking, Predator is the second half of a spyware duo designed to monitor iOS and Android users. The first component is named Alien; it’s responsible for compromising a device and installing Predator. As you might’ve guessed, these pieces of malware are named after the famous Alien vs. Predator franchise.

An attack using Intellexa’s software typically begins with a message containing a malicious link. When the victim clicks it, they’re directed to a site that leverages a chain of browser and OS vulnerabilities to infect the device. To keep things looking normal and avoid raising suspicion, the user is then redirected to a legitimate website.

Besides Alien, Intellexa offers several other delivery vehicles for landing Predator on a target’s device. These include the Mars and Jupiter systems, which are installed on the service provider’s side to infect devices through a man-in-the-middle attack.

Predator spyware for iOS comes packed with a wide array of surveillance tools. Most notably, it can record and transmit data from the device’s camera and microphone. Naturally, to keep the user from catching on to this suspicious activity, the system’s built-in recording indicators — the green and orange dots at the top of the screen — must be disabled. While it’s been known for some time that Predator could somehow hide these alerts, it’s only thanks to this research that we know how exactly it pulls it off.

How the iOS camera and microphone indicator system works

To understand how Predator disables these indicators, we first need to look at how iOS handles them. Since the release of iOS 14 in 2020, Apple devices have alerted users whenever the microphone or camera is active by displaying an orange or green dot at the top of the screen. If both are running simultaneously, only the green dot is shown.

Just like other iOS user interface elements, recording indicators are managed by a process called SpringBoard, which is responsible for the device’s system-wide UI. When an app starts using the camera or microphone, the system registers the change in that specific module’s state. This activity data is then gathered by an internal system component, which passes the information to SpringBoard for processing. Once SpringBoard receives word that the camera or microphone is active, it toggles the green or orange dot on or off based on that data.

From an app’s perspective, the process works like this: first, the app requests permission to access the camera or microphone through the standard iOS permission mechanism. When the app actually needs to use one or both of these modules, it calls the iOS system API. If the user has granted permission, iOS activates the requested module and automatically updates the status indicator. These indicators are strictly controlled by the operating system; third-party apps have no direct access to them.

How Predator interferes with the iOS camera and microphone indicators

Cybersecurity researchers analyzed a captured version of Predator and uncovered traces of multiple techniques used by the spyware’s creators to bypass built-in iOS mechanisms and disable recording indicators.

In the first approach — which appears to have been used during early development — the malware attempted to interfere with the indicators at the display stage right after SpringBoard received word that the camera or microphone was active. However, this method was likely deemed too complex and unreliable by the developers. As a result, this specific function remains in the Trojan as dead code — it’s never actually executed.

Ultimately, Predator settled on a simpler, more effective method that operates at the very level where the system receives data about the camera or microphone being turned on. To do this, Predator intercepts the communication between SpringBoard and the specific component responsible for collecting activity data from these modules.

By exploiting the specific characteristics of Objective-C — the programming language used to write the SpringBoard application — the malware completely blocks the signals indicating that the camera or microphone has been activated. As a result, SpringBoard never receives the signal that the module’s status has changed, so it never triggers the recording indicators.

How to lower your risk of spyware infection

Predator-grade spyware is quite expensive, and typically reserved for high-stakes industrial or state-sponsored espionage. On one hand, this means defending against such a high-tier threat is difficult — and achieving 100% protection is likely impossible. On the other hand, for these same reasons, the average user is statistically unlikely to be targeted.

However, if you’ve reason to believe you’re at risk from Predator or Pegasus-class spyware, here are a few steps you can take to make an attacker’s job much harder:

• Don’t click suspicious links from unknown senders.
• Regularly update your operating system, browsers, and messaging apps.
• Reboot your device occasionally. A simple restart can often help “lose the tail”, forcing attackers to reinfect the device from scratch.
• Install a reliable security solution on all the devices you use.

Today, Microsoft is announcing a coordinated legal action in the United States and, for the first time, the United Kingdom to disrupt RedVDS, a global cybercrime subscription service fueling millions in fraud losses. These efforts are part of a broader joint operation with international law enforcement, including German authorities and Europol, which has allowed Microsoft and its partners to seize key malicious infrastructure and take the RedVDS marketplace offline, a major step toward dismantling the networks behind AI-enabled fraud, such as real estate scams. 

For as little as US $24 a month, RedVDS provides criminals with access to disposable virtual computers that make fraud cheap, scalable, and difficult to trace. Services like these have quietly become a driving force behind today’s surge in cyber‑enabled crime, powering attacks that harm individuals, businesses, and communities worldwide. Since March 2025, RedVDS‑enabled activity has driven roughly US $40 million in reported fraud losses in the United States alone. Among the victims is H2-Pharma, an Alabama‑based pharmaceutical company that lost more than $7.3 million — money supposed to be used to sustain lifesaving cancer treatments, mental health medications, and children’s allergy drugs  for patients across the country. In a separate case, the Gatehouse Dock Condominium Association in Florida was tricked out of nearly $500,000—funds contributed by residents and property owners for essential repairs. Both organizations are joining Microsoft as co‑plaintiffs in this civil action. 

But these cases represent only a fraction of the harm. Fraud and scams frequently go unreported, victims are global, and cybercriminals routinely pivot across platforms and service providers. For the individual, fraud has lasting effects that extend beyond financial loss to emotional wellbeing, health, relationships, and long-term stability. As a result, the true toll of RedVDS‑enabled activity is far higher than the roughly US $40 million Microsoft can directly observe.

What RedVDS is—and why it matters

RedVDS is an online subscription service that is part of the growing cybercrime-as-a-service ecosystem where cybercriminals buy and sell services and tools to launch attacks at scale. It provides access to cheap, effective, and disposable virtual computers running unlicensed software, including Windows, allowing criminals to operate quickly, anonymously, and across borders.

Cybercriminals use RedVDS for a wide range of activities, including sending high‑volume phishing emails, hosting scam infrastructure, and facilitating fraud schemes. RedVDS is frequently paired with generative AI tools that help identify high‑value targets faster and generate more realistic, multimedia message email threads that mimic legitimate correspondences. In hundreds of cases, Microsoft observed attackers further augment their deception by leveraging face-swapping, video manipulation, and voice cloning AI tools to impersonate individuals and deceive victims.

In just one month, more than 2,600 distinct RedVDS virtual machines sent an average of one million phishing messages per day to Microsoft customers alone. While most were blocked or flagged as part of the 600 million cyberattacks Microsoft blocks per day, the sheer volume meant a small percentage may have succeeded in reaching the targets’ inboxes. Since September 2025, RedVDS‑enabled attacks have led to the compromise or fraudulent access of more than 191,000 organizations worldwide. These figures represent only a subset of the impacted accounts across all technology providers, illustrating how quickly this infrastructure increases the scale of cyberattacks.

How RedVDS enables fraud

One of the most common ways RedVDS‑enabled attacks result in financial loss is through payment diversion fraud, also known as business email compromise, or “BEC.” In these schemes, attackers gain unauthorized access to email accounts, quietly monitor ongoing conversations, and wait for the right moment, such as an upcoming payment or wire transfer. At that point, they impersonate a trusted party and redirect funds, often moving the money within seconds. Both H2-Pharma and the Gatehouse Dock Condominium Association were targeted through sophisticated BEC schemes that exploited trust and timing.

 

RedVDS has also been heavily used to facilitate real estate payment diversion scams, one of the fastest‑growing forms of cyber‑enabled fraud. In these cases, attackers compromise the accounts of realtors, escrow agents, or title companies and send strategically timed emails with fraudulent payment instructions designed to divert closing funds, escrow payments, and other sizeable transactions. For families and first altogether. Microsoft has observed RedVDS‑enabled activity affecting more than 9,000 customers in the real estate sector alone, with particularly severe impact in countries such as Canada and Australia.

And the threat goes far beyond real estate. RedVDS‑enabled scams have hit construction, manufacturing, healthcare, logistics, education, legal services, and many other sectors—disrupting everything from production lines to patient .

A Global Response to a Global Threat

Cybercrime today is powered by shared infrastructure, which means disrupting individual attackers is not enough. Through this coordinated action, Microsoft has disrupted RedVDS’s operations, including seizing two domains that host the RedVDS marketplace and customer portal, while also laying the groundwork to identify the individuals behind them.

Microsoft’s legal actions are reinforced by close collaboration with law enforcement partners around the world, further disrupting the malicious operation. Germany’s Public Prosecutor’s Office Frankfurt am Main – Central Office for Combating Internet Crime (ZIT) and the German State Criminal Police Office Brandenburg have seized a critical server used to power RedVDS, effectively taking its central marketplace offline. At the same time and as part of this ongoing disruption, Microsoft is also working closely with international law enforcement, including Europol’s European Cybercrime Centre (EC3), to disrupt the broader network of servers and payment networks that supported RedVDS customers as part of the ongoing disruption.What people and organizations can do

We are deeply grateful to H2– -Pharma and the Gatehouse Dock Condominium Association for their willingness to come forward and share their experiences. Their cooperation, combined with Microsoft’s threat intelligence, made this action possible and will help protect future victims. Falling victim to a scam should never carry stigma. These attacks are executed by organized, professional criminal groups that intercept and manipulate legitimate communications between trusted parties.

Simple steps can significantly reduce risk, including slowing down and questioning urgency, calling points of contact back using numbers that are already known to you, verifying payment requests using additional contact information, enabling multifactor authentication, watching carefully for subtle changes in email addresses, keeping software up to date, and reporting suspicious activity to law enforcement. Every report helps dismantle networks like RedVDS and brings us closer to stopping cybercrime at scale.

Continuing a collective effort to disrupt cybercrime

This action against RedVDS builds on Microsoft’s ongoing efforts to disrupt fraud and scam infrastructure through legal and technical action, collaboration with law enforcement, and participation in global initiatives such as the National Cyber-Forensics and Training Alliance (NCFTA) and the Global Anti-Scam Alliance (GASA). It marks the 35th civil action targeting cybercrime infrastructure by Microsoft’s Digital Crimes Unit, underscoring a sustained strategy to go beyond individual takedowns and dismantle the services that criminals rely on to operate and scale.

As services like RedVDS continue to emerge, Microsoft will keep working with partners across sectors and borders to identify and disrupt the infrastructure behind cyber-enabled fraud, making it harder for criminals to profit and easier for people and organizations to stay safe online.
