Hackers Strike a Major Fabric Supplier for H&M, Adidas, and More: What the Cyber Breach Means for the Industry

In today’s hyperconnected world where every click, transaction, and bit of data can be a potential vulnerability, a new cyberattack sends shockwaves across the retail and manufacturing sectors. The latest victim in a relentless wave of breaches is Fulgar, a key fabric supplier for major global brands, including H&M, Adidas, and others. Infamous cyber extortion group RansomHouse has claimed responsibility for the breach, reportedly exposing sensitive data such as financial records, client information, and details about the company’s multinational operations.

As the digital landscape continues to evolve, so does the audacity and sophistication of cybercriminal groups. Fulgar’s case underscores the growing vulnerability of critical supply chain infrastructures and raises critical questions about how these breaches could cascade throughout industries. Here’s a comprehensive breakdown of what happened, why it matters, and what lessons businesses can glean from this alarming incident.

The Fulgar Breach: What We Know

On November 17, 2025, reports confirmed that hackers had infiltrated the systems of Fulgar, a leading supplier of fabric and textile solutions to some of the world’s largest clothing brands. This attack is attributed to RansomHouse, a notorious hacking collective that has made headlines in recent years for targeting organizations to extort money in exchange for withheld or stolen data.

According to information released post-attack, Fulgar’s critical digital infrastructure was compromised, leading to the exposure of:

• Financial data: Critical information about Fulgar’s revenues, expenditures, and potentially payroll details has been leaked.

• Client networks: Sensitive partnerships with big fashion brands like Adidas and H&M were exposed, detailing Fulgar’s relationships and possibly revealing competitive trade secrets.

• Global operational blueprints: The attack revealed intellectual property and logistical data about Fulgar’s operations spanning multiple countries.

While the full extent of the breach’s repercussions is still unfolding, experts suspect profound consequences not only for Fulgar but also for the broader global supply chain in the retail and fashion industries.

RansomHouse: A Cyber Gang with a Track Record

RansomHouse isn’t a new name in cybercrime. Known for exploiting vulnerabilities in organizations with outdated or insufficient IT security infrastructures, the group employs a potent mix of ransomware and data exfiltration tactics. Their modus operandi is simple but chilling: encrypt a company’s internal systems, steal sensitive data, and threaten to release it unless a hefty payout is made.

What makes RansomHouse particularly dangerous is their public leaking strategy. In many documented cases, including this breach, even a refusal to pay does not mean companies escape scot-free—data often ends up published online, fueling further threats, reputational damage, and even legal complications for the victims.

With Fulgar now added to their list of targets, it becomes clear that even companies operating behind the scenes—like fabric suppliers—are as vulnerable as front-facing, high-profile brands. This highlights how no organization in the supply chain is immune from these attacks.

Which Companies Could Be Affected?

Fulgar’s clients include some of the world’s most recognizable fashion and retail brands. While neither Adidas nor H&M has released public statements regarding the breach yet, the ramifications of compromised supplier data could be profound.

Here are some areas of potential fallout:

• Operational Delays: A disruption in Fulgar’s systems could slow down fabric manufacturing and distribution processes, leading to delays in clothing production for major retail seasons.

• Intellectual Property Theft: If sensitive product designs or proprietary manufacturing processes were accessed, competitors or unauthorized parties may now have vital insights into Fulgar’s operations.

• Customer Trust Erosion: Brands reliant on Fulgar’s services may face customer backlash for being connected to an insecure supply chain, particularly if consumer or shop-level data is found to have been compromised.

• Market Competition Risks: With potential trade secrets leaked to the public, smaller or rival brands may find opportunities to close gaps or replicate industry advantages.

The incident also underscores a vital concern: can businesses fully trust third-party vendors with sensitive logistical and client data? This is becoming a crucial factor for security-conscious enterprises.

Supply Chain Risks in the Modern Era

This breach is a case study in how cyber risks permeate far deeper than just customer-facing companies. Supply chains—once thought of as merely back-end business processes—are increasingly emerging as critical vulnerabilities in today’s retail ecosystem.

Relying on third-party suppliers amplifies cybersecurity risks for several reasons:

• Shared IT systems: Many suppliers integrate their systems into the broader network of their corporate clients. A breach at one end of the pipeline can provide hackers with a backdoor to attack other entities in the chain.

• Complex supply chain webs: The fabric industry is particularly intricate, relying on a globalized web of manufacturers, distributors, and retailers. One security lapse can echo across multiple countries and affect countless stakeholders.

• Decentralized data management: Data silos across various supply chain parties can make implementing cohesive cybersecurity strategies more difficult.

It’s clear that manufacturers and suppliers now sit at the frontlines of the cybersecurity battlefield, with their breaches threatening the larger ecosystem within which they operate.

How Businesses Can Bolster Cybersecurity

For companies watching from the sidelines, Fulgar’s troubles serve as a wake-up call to evaluate their own cybersecurity frameworks. Here are five best practices organizations across industries should implement to mitigate such risks:

• Conduct Penetration Testing: Regularly test IT environments for vulnerabilities hackers might exploit.

• Training and Education: Employees are often the weakest link in security protocols. Robust training can prevent common errors like phishing attacks or credential misuse.

• Zero Trust Model: Adopt a “zero trust” approach to network access, only granting permissions to verified users and ensuring that internal privileges are limited.

• Vendor Risk Management: Work closely with all third-party vendors to ensure they adhere to strict cybersecurity guidelines and protocols.

• Incident Response Plans: Even the best defenses may falter. Having a well-documented incident response playbook can mitigate the chaos that follows security breaches.

The Bigger Picture: A New Wave of Cybersecurity Challenges

Fulgar’s breach isn’t an isolated case—it represents the broader challenges industries now face in the escalating fight against cybercrime. Manufacturers, retailers, and even customers are increasingly connected. While this connectivity brings efficiency and innovation, it also broadens the attack surface hackers can target.

What’s particularly unsettling is the trend toward more aggressive tactics. Groups like RansomHouse don’t just paralyze systems with ransomware—they release sensitive information online, making their attacks harder to contain and multiplying the damages.

Governments are stepping up with stricter regulations for data privacy and cybersecurity requirements, but businesses themselves also need to think proactively. By prioritizing cyber resilience and preparing for threats beyond the immediate horizon, companies can limit fallout from future attacks.

Conclusion: A Wake-Up Call for the Supply Chain

The Fulgar breach should resonate as a cautionary tale for every business operating in a globalized supply chain. While fashion brands like Adidas and H&M are yet to release an official statement, it’s evident that the ripple effects of this attack could extend far beyond Fulgar’s digital borders.

Key takeaways from this incident include:

• No organization is “too back-end” to be a target. Suppliers, manufacturers, and other supporting players are now critical nodes in hackers’ maps.

• Proactive cybersecurity measures are non-negotiable. Organizations must carefully evaluate and strengthen their own infrastructure and those of their partners.

• Reputation damage can be as costly as operational delays or legal fines. A single breach can corrode trust across decades-old relationships.

The question now isn’t if another major attack will happen—it’s when. The only sustainable way forward is by fostering a culture of security awareness, bolstered by cutting-edge technology and robust collaboration across the supply chain.

Let the Fulgar breach serve as both a warning and an opportunity. It’s time businesses weave cybersecurity into their very fabric, becoming as resilient digitally as they are operationally.
