Iranian Hackers Launch New Campaign Against US Targets

American companies are facing a fresh wave of cyberattacks from a familiar adversary. The Iranian hacking group MuddyWater has been actively targeting US organizations since early February, continuing its operations even after recent military strikes against Iran. Security researchers at Broadcom’s Symantec and Carbon Black Threat Hunter Team uncovered the campaign, which shows no signs of slowing down.

Who’s in the crosshairs? The list includes a major US bank, a US airport, and several non-governmental organizations operating in both the US and Canada. Even the Israeli branch of a US software company that supplies the defense and aerospace industry found itself under scrutiny. Each of these entities reported suspicious network activity in recent weeks, signaling a broad and persistent threat.

Unmasking the Dindoor Backdoor

At the heart of this campaign is a newly discovered piece of malware researchers have named ‘Dindoor.’ This backdoor represents a new tool in MuddyWater’s arsenal. It was discovered on the networks of the Israeli software company outpost, the targeted US bank, and a Canadian non-profit.

Dindoor operates with a clever disguise. It uses a digital certificate issued to “Amy Cherne” and leverages Deno, a secure runtime for JavaScript and TypeScript, to execute its commands. This technique helps the malware blend in with legitimate software. In one attempted breach, the hackers tried to steal data from the software company using Rclone, a common file management tool, directing it to a Wasabi cloud storage bucket. Whether that data theft succeeded remains unclear.

The Telltale Sign: Reused Hacker Certificates

How do researchers know MuddyWater is behind this? The evidence lies in the digital fingerprints left behind. On the US airport’s network, a different backdoor called ‘Fakeset’ was found. This Python-based malware was signed with two certificates: one for “Amy Cherne” and another for “Donald Gay.”

That second name is a major clue. The “Donald Gay” certificate has a history. It has been used repeatedly to sign malware definitively linked to MuddyWater, a group active since 2017 and associated with Iran’s Ministry of Intelligence and Security. Security experts also track this group under names like Seedworm, Temp Zagros, and Static Kitten. The Fakeset backdoor itself was downloaded from servers belonging to the cloud storage company Backblaze.

The connection deepens. The same Donald Gay certificate was used to sign a sample of ‘Stagecomp’ malware, which is designed to download the ‘Darkcomp’ backdoor. Both Stagecomp and Darkcomp have been publicly attributed to MuddyWater by giants in the security industry, including Google, Microsoft, and Kaspersky. While these specific malware families weren’t found on the newly targeted networks, the reuse of these distinctive certificates strongly points to the same actor.

A Persistent and Evolving Threat

What does this mean for other organizations? The Threat Hunter Team issued a stark warning. “While we have disrupted these breaches, other organizations could still be vulnerable to attack,” they stated. The campaign demonstrates MuddyWater’s adaptability—shifting tools, reusing trusted infrastructure, and persistently targeting critical sectors.

The group’s focus on a defense supplier, financial institution, and transportation hub highlights its strategic interests. This isn’t random digital vandalism; it’s a coordinated intelligence-gathering operation. The continued activity after geopolitical events shows these hackers operate on their own timeline, driven by long-term objectives rather than short-term political reactions. For security teams, the message is clear: vigilance and awareness of these evolving tactics are non-negotiable.

France Ditches Windows for Linux: A Bold Move Toward Digital Sovereignty

In a significant shift, France has announced plans to replace Microsoft Windows with Linux on thousands of government computers. This decision, part of a broader push for digital sovereignty, aims to reduce the country’s dependence on American technology. The move reflects growing unease across Europe about relying on US-based tech giants amid geopolitical instability.

Why France Ditches Windows for Linux Now

The French government’s decision comes as a direct response to concerns over data control and infrastructure security. In a statement, French minister David Amiel emphasized the need to “regain control of our digital destiny.” He argued that France can no longer accept a situation where its data and digital systems are tied to US companies.

This shift is not sudden. It follows a pattern of increasing distrust toward American tech firms, especially after recent actions by the Trump administration. Sanctions and trade disruptions have made European leaders acutely aware of their vulnerabilities.

As a result, France ditches Windows for Linux not just as a technical upgrade, but as a strategic move to bolster national autonomy.

The Linux Migration Plan: What We Know So Far

The transition will begin with computers at the French government’s digital agency, DINUM. While no specific timeline or Linux distribution has been announced, the government is exploring various open source options tailored for enterprise use.

Linux, being free and highly customizable, offers France the flexibility to adapt its operating system to specific government needs. This contrasts sharply with proprietary software like Windows, which ties users to Microsoft’s ecosystem and licensing fees.

Building on this, the French government has also taken other steps to reduce US tech reliance. Earlier this year, it stopped using Microsoft Teams for video conferencing, switching to Visio, a French-developed tool based on the open source platform Jitsi.

Health Data Platform Migration

In addition to the operating system shift, France plans to migrate its health data platform to a new trusted system by the end of the year. This move underscores a broader commitment to securing sensitive citizen data within national borders.

Digital Sovereignty: A European Trend

France is not alone in this endeavor. Across Europe, lawmakers are waking up to the risks of over-reliance on US technology. In January, the European Parliament voted to adopt a report directing the European Commission to identify areas where the EU can reduce its dependence on foreign providers.

This trend, often called digital sovereignty, is gaining momentum. Countries like Germany and the Netherlands have also explored open source alternatives for government systems. However, France’s latest move is one of the most high-profile examples yet.

Therefore, when France ditches Windows for Linux, it sends a powerful signal to other nations: the era of unquestioned US tech dominance may be waning.

Challenges and Opportunities Ahead

Migrating an entire government infrastructure to Linux is no small feat. Compatibility issues, training costs, and software dependencies pose significant hurdles. However, the long-term benefits—including cost savings, enhanced security, and greater control—are compelling.

Additionally, the French government plans to invest in local tech ecosystems, fostering homegrown innovation. This aligns with the broader goal of reducing reliance on US tech giants like Microsoft, Amazon, and Google.

What This Means for the Future of Tech

France ditches Windows for Linux at a time when global tech alliances are shifting. As nations prioritize data sovereignty and cybersecurity, open source platforms are becoming increasingly attractive.

This move could inspire other countries to follow suit, accelerating the adoption of open source in government. It also puts pressure on US tech companies to adapt—or risk losing lucrative government contracts.

How Anthropic’s Claude AI Uncovered a Hidden Apache ActiveMQ Vulnerability After 13 Years

For more than a decade, a critical security flaw lurked undetected within Apache ActiveMQ Classic, a widely used open-source message broker. The bug, recently identified as CVE-2026-34197, was finally exposed with the help of Anthropic’s AI assistant, Claude. This discovery highlights the growing role of artificial intelligence in cybersecurity and vulnerability research.

The flaw, categorized as a remote code execution (RCE) vulnerability, allows attackers to execute arbitrary operating system commands on affected systems. Horizon3.ai chief architect Naveen Sunkavally detailed the discovery in an April 7 blog post, emphasizing that organizations running ActiveMQ should prioritize patching immediately.

According to Sunkavally, “An attacker can invoke a management operation through ActiveMQ’s Jolokia API to trick the broker into fetching a remote configuration file and running arbitrary OS commands.” The vulnerability requires credentials, but default credentials (admin:admin) are common in many environments. On versions 6.0.0 through 6.1.1, no credentials are required due to another issue, CVE-2024-32114, which exposes the Jolokia API without authentication. In those versions, CVE-2026-34197 becomes an unauthenticated RCE threat.

Understanding the Apache ActiveMQ Bug and Its Impact

This Apache ActiveMQ bug has remained hidden for 13 years because it involves multiple components developed independently over time. In isolation, each feature appeared safe, but when chained together, they created a dangerous exploit path. Sunkavally noted that this is exactly where Claude excelled—efficiently stitching together the attack path end to end with a clear head free of assumptions.

“Something that would have probably taken me a week manually took Claude 10 minutes,” he said. The AI’s ability to analyze source code and identify complex interactions between components made it an invaluable tool in this discovery.

How the Vulnerability Works

The exploit leverages ActiveMQ’s Jolokia API, a management interface that allows remote access to the broker’s internal operations. By sending a crafted POST request to /api/jolokia/ containing an addNetworkConnector command, an attacker can trick the broker into fetching a malicious remote configuration file. This file then triggers the execution of arbitrary OS commands, granting the attacker control over the system.

Organizations concerned about potential compromise should check ActiveMQ broker logs for network connector activity referencing vm:// URIs with brokerConfig=xbean:http. Additional indicators of compromise include:

  • POST requests to /api/jolokia/ containing addNetworkConnector in the request body
  • Outbound HTTP requests from the ActiveMQ broker process to unexpected hosts
  • Unexpected child processes spawned by the ActiveMQ Java process

Patches and Mitigation Steps for the ActiveMQ RCE Vulnerability

The ActiveMQ RCE vulnerability has been patched in ActiveMQ Classic versions 5.19.4 and 6.2.3. Users are strongly advised to update to these versions immediately. Additionally, ensure that no default credentials are in use. Changing the default admin:admin credentials is a critical step, as many environments still rely on these weak passwords.

For organizations unable to patch immediately, implementing network segmentation and restricting access to the Jolokia API can help reduce risk. Monitoring for the indicators of compromise listed above is also essential for early detection.

Claude AI: A New Tool for Vulnerability Hunting

Sunkavally described the discovery of CVE-2026-34197 as “80% Claude and 20% gift-wrapping by a human.” He regularly uses Claude to take a first pass at source code for vulnerability hunting, prompting it lightly and setting up a target on the network for it to validate findings.

“A lot of the time, Claude finds interesting stuff but it doesn’t quite rise to the level of a CVE I’d bother reporting. In this case, it did a great job, with nothing more than a couple of basic prompts,” he said.

This case demonstrates how AI can accelerate vulnerability research, especially for bugs that involve complex interactions across multiple components. Sunkavally urged appsec engineers and developers to adopt tools like Claude in their workflows, stating that “anyone with a security background can take advantage.”

As AI continues to evolve, its role in cybersecurity will likely expand. For more insights on AI-driven security research, explore our article on how artificial intelligence is transforming threat detection.

Final Thoughts on the 13-Year-Old Bug

The discovery of this Apache ActiveMQ bug serves as a stark reminder that vulnerabilities can remain hidden for years, especially when they involve multiple independent components. The use of AI tools like Claude can help uncover these hidden threats more efficiently than traditional manual methods.

Organizations running ActiveMQ should act quickly to patch and review their security posture. By combining AI-powered vulnerability hunting with robust security practices, the cybersecurity community can stay ahead of evolving threats.

New Hack-for-Hire Campaign Hits Android Devices and iCloud Backups Across the Middle East

Security researchers have uncovered a sophisticated hack-for-hire group that has been targeting journalists, activists, and government officials across the Middle East and North Africa. This campaign, active between 2023 and 2025, uses phishing attacks to access iCloud backups and deploy Android spyware, raising fresh concerns about the growing private espionage industry.

According to reports from Access Now, SMEX, and Lookout, the hackers employed a range of tactics to infiltrate devices. For iPhone users, they tricked victims into surrendering Apple ID credentials, gaining access to iCloud backups that contained the full contents of their phones. For Android users, they distributed spyware called ProSpy, disguised as popular apps like Signal, WhatsApp, and Zoom, as well as regional messaging apps ToTok and Botim.

This hack-for-hire group appears to be an offshoot of the infamous Indian startup Appin, which was exposed by Reuters in 2022 and 2023 for allegedly hacking corporate executives and government officials. Justin Albrecht, principal researcher at Lookout, noted that while Appin has since shut down, its operations have simply migrated to smaller companies like RebSec, which has since deleted its online presence.

How the Hack-for-Hire Group Operates

The campaign targeted at least three journalists—two in Egypt and one in Lebanon—but Lookout’s investigation suggests the scope is much wider. Victims include government officials in Bahrain, Egypt, the United Arab Emirates, Saudi Arabia, and even individuals in the United Kingdom and possibly the United States. The researchers linked the group to BITTER APT, a hacking collective suspected of ties to the Indian government.

One of the most alarming aspects of this hack-for-hire group is its use of “plausible deniability.” By outsourcing operations to private vendors, governments can avoid direct responsibility. “These operations have become cheaper and it’s possible to evade responsibility, especially since we won’t know who the end customer is,” said Mohammed Al-Maskati, an investigator at Access Now.

Android Spyware and Phishing Attacks: The Technical Details

For Android users, the hackers deployed ProSpy, a spyware that masquerades as legitimate apps. Victims were lured into downloading fake versions of Signal, WhatsApp, or other messaging tools, which then granted attackers full control over the device. This Android spyware could capture messages, photos, and even microphone and camera access.

For iPhone users, the approach was different but equally dangerous. Hackers used phishing emails and messages to trick targets into revealing their Apple ID credentials. Once obtained, they accessed iCloud backups, effectively bypassing iOS security without needing expensive zero-day exploits. As Access Now noted, this is “potentially a cheaper alternative to the use of more sophisticated and expensive iOS spyware.”

Signal Account Hijacking

In some cases, the hackers attempted to register a new device—controlled by them—to the victim’s Signal account. This technique, popular among various hacking groups including Russian spies, allows attackers to intercept encrypted messages without breaking Signal’s encryption itself.

The Growing Threat of Commercial Spyware

This campaign highlights a troubling trend: the rise of commercial spyware and hack-for-hire services that are more accessible than ever. Unlike state-sponsored operations, these private groups offer lower costs and greater anonymity. “For their customers, these hack-for-hire groups are likely cheaper than purchasing commercial spyware,” Albrecht explained.

Building on this, the researchers emphasize that even less sophisticated tools can be highly effective. The hackers behind this campaign may not have the most advanced exploits, but their social engineering and phishing tactics proved sufficient to compromise high-value targets.

What This Means for Digital Security

For journalists and activists in the Middle East, this campaign serves as a stark reminder of the risks they face. As a result, experts recommend enabling two-factor authentication on all accounts, avoiding suspicious links, and regularly reviewing connected devices. For organizations, investing in security awareness training and monitoring for unusual account activity is crucial.

This discovery also underscores the need for stronger regulation of the spyware industry. While some governments have begun to address the issue, the shadowy nature of these companies makes enforcement difficult. The Indian embassy in Washington, D.C. did not respond to requests for comment.
