This week, Adidas—the global sportswear titan—became the latest cautionary tale in a long line of high-profile cyberattacks. But this breach, rooted in a third-party customer service provider, goes beyond the headlines. It’s a sharp reminder of systemic vulnerabilities facing enterprises today and a wake-up call for CIOs and CISOs alike.
This article provides a deep dive into the Adidas incident from an analyst’s lens, unpacking not only what happened but why it matters, how organizations can avoid similar pitfalls, and what a modern cybersecurity threat intelligence framework should look like.
What Happened: The Breach in Brief
On May 23, 2025, Adidas confirmed that an unauthorized third party accessed consumer contact data via a third-party customer support vendor. Importantly, no payment information or passwords were compromised. The data leak largely involved customer email addresses, phone numbers, and other contact details—seemingly harmless, yet potent fuel for phishing, social engineering, and identity fraud.
Adidas acted quickly: launching a full-scale investigation, bringing in forensic cybersecurity experts, and notifying both affected customers and regulatory bodies under GDPR and global data protection laws.
But for seasoned cybersecurity professionals, this was not merely an isolated incident—it was a textbook case of supply chain exposure, one of the most pressing threats in modern enterprise cybersecurity.

Analyst’s Insight: The Third-Party Blind Spot
Third-party and supply chain risks are basically the weak link in modern cybersecurity. A recent Ponemon report shows that over half of orgs—yep, 53%—got hit by a data breach in the last two years because of a partner or vendor slip-up.
“When you outsource services, you also outsource risk—unless you bring third-party cybersecurity into your governance framework.”
— Sudipto Ghosh, Head of Global Marketing, Intent Amplify
Adidas is far from alone.
Remember SolarWinds in 2020, Kaseya in 2021, and MOVEit in 2023? All major hits where hackers went after the weakest link—third-party vendors. The lesson for CISOs and execs? Vendor risk isn’t just an IT problem anymore—it’s a top-level, boardroom convo now.
In fact, Adidas itself isn’t a virgin victim to cyberattacks. In 2018, the company suffered a major attack on its customer database in the US, “wiping” millions of dollars in a day! Yes, we remember.
Our cybersecurity analysts spoke to thought leaders in the cybersecurity technology industry.
Jason Soroko, Senior Fellow at Sectigo, a Scottsdale, Arizona-based provider of comprehensive certificate lifecycle management (CLM) said, “Adidas’ press note does not offer a vendor name, but it exposes an industry blind spot, which is “call-center exhaust”. Attackers didn’t chase card data, but they siphoned the valuable commodity inside ticket logs-verified emails, phone numbers, shipping addresses, and conversational snippets that reset security questions in downstream systems. Because many global retailers funnel multiple brands through the same BPO platforms, one breach seeds cross the brand credential stuffing and warranty fraud campaigns at scale.”
Jason added, “Under the EU’s NIS2 supply-chain clauses taking effect later this year, Adidas must prove it had vendor controls for data minimization and tokenization and not just PCI segregation. Regulators will ask why PII records were still sitting in a provider’s CRM years after ‘the last sneaker return’. Treat customer service transcripts as high-risk assets and isolate them with zero-trust segmentation before the next attacker does.”
Jonathan Stross, SAP Security Analyst at Pathlock, said, “This breach underscores the importance of establishing quality gates and data loss prevention for third-party software. While the company’s developments are being secured through agile processes and code reviews, third-party software tends to be blindly trusted.
For all code changes, regardless of origin, testing and validating adherence to up-to-date security standards is mandatory, even in cases where a third party can be held accountable.
Additionally, third-party software often lacks the reporting API’s and capabilities to alert or block certain access when an unusually high amount of traffic is being generated, which can indicate a data export.”
Jonathan added, “Affected customers should watch out for unsolicited messages, spam, and in general, unusual traffic. Attackers may use this to launch phishing attempts. Even though financial data wasn’t leaked, contact information can still be used for identity fraud.”
What Cyber Threat Intelligence (CTI) Looks Like in 2025
If your organization is still relying on a basic SIEM (Security Information and Event Management) tool and annual vendor questionnaires, you’re underprepared.
Fletcher Davis, Senior Security Research Manager at BeyondTrust, highlighted the importance of mandating security assessments and upgraded cybersecurity policies in 2025, to thwart such attacks from taking down operations.
Fletcher said, “This incident underscores a critical truth: third-party breaches swiftly become your organization’s breaches, which highlights the necessity of robust oversight mechanisms. Mandating security assessments, multi-factor authentication, and zero-trust architecture for all vendor access, while deploying real-time identity infrastructure monitoring to cut response times to minutes, as opposed to days.
Organizations must pivot from merely controlling who has access to also strictly managing how and where access is granted. Deploying conditional access policies that restrict credentials to specific IP ranges or predefined systems can dramatically minimize exposure. Comprehensive visibility into all privileged identities, human and non-human, should be the norm, enabling proactive identification of overprivileged and hidden vulnerabilities before exploitation occurs.”
A mature Cyber Threat Intelligence (CTI) capability in 2025 should include:
- Automated Risk Scoring of Vendors: Real-time risk visibility into the security posture of third parties using threat feeds and external attack surface assessments.
- Behavioral Anomaly Detection: AI-powered tools to detect out-of-pattern behaviors within vendor systems, such as abnormal data queries or excessive downloads.
- Supply Chain Attack Simulations: Regular red-team exercises simulating vendor compromise scenarios.
- Zero Trust Architecture: Ensuring third-party access is continuously verified, context-aware, and strictly permissioned.
- Advanced Threat Intelligence: Use of next-gen security incident identification solutions for different workplace structures — On-site, remote, and hybrid.
Prevention: What Organizations Can Do Right Now
For CISOs and CIOs, the Adidas breach underscores five actionable priorities:
- Map Your Vendor Ecosystem: Most companies underestimate how many third parties have access to internal systems. Create and continuously update an inventory of all vendors, categorize them by risk, and ensure they follow secure access protocols.
- Mandate Security SLAs in Vendor Contracts: Every vendor agreement should include cybersecurity SLAs: breach notification timelines, security control requirements, and rights to audit.
- Enforce Principle of Least Privilege (PoLP): Vendors should only have access to the data and systems they need—nothing more.
- Implement Continuous Monitoring: Periodic audits aren’t enough. Use tools that provide real-time visibility into vendor system interactions and unusual data flows.
- Invest in Crisis Response Playbooks: When a breach happens, time is everything. Have a tested incident response plan, media communications strategy, and cross-functional response team ready.

CIO and CISO Advisory: The Strategic Perspective
For the CIO:
- Prioritize cybersecurity investments aligned with business impact. Use incidents like Adidas’ to make the case for budget reallocations and board-level support for cyber risk management.
- Push for a unified IT-GRC (governance, risk, compliance) strategy that ties vendor oversight directly to enterprise risk profiles.
For the CISO:
- Stop thinking ‘how do we block every breach?’ and start thinking ‘how fast can we catch and kill it when it happens?’ Assume compromise, detect early, contain faster.
- Collaborate with procurement and legal teams to embed security requirements from RFP to contract.
- Elevate third-party risk to your executive dashboard—make it as visible as phishing or ransomware.
The Road Ahead: Securing the Digital Supply Chain
The Adidas hack wasn’t a total meltdown, but it’s a solid example of a bigger problem we’re seeing everywhere.
As digital ecosystems grow more complex and interconnected, organizations can no longer treat vendor security as a checkbox.
Adidas’ quick containment and transparency are commendable. But true resilience lies in proactive defense, built on data-driven threat intelligence, continuous monitoring, and cross-enterprise coordination.
For the security community, the message is loud and clear: the front line no longer stops at your firewall. It extends into every third-party connection—and we must defend it as such.
