5 Identity-Based Attack Vectors Breaching Retailers (and How to Spot Them Before It’s Too Late)

The retail world just had its wake-up call. In the past few months alone, industry giants like Adidas, The North Face, Dior, Victoria’s Secret, Cartier, Marks & Spencer, and Co-op have made headlines—not for blockbuster sales or new collections, but for data breaches that exposed millions of customer records.

But here’s the catch: These weren’t the kind of attacks the movies love—no mysterious malware, no cutting-edge zero-day exploits. Instead, the attackers simply logged in. They slipped through the cracks using legitimate credentials and overprivileged accounts, often left wide open and unmonitored in the sprawl of SaaS (Software as a Service) applications.

The new battleground isn’t on the endpoint. It’s in the invisible web of identities and integrations that power modern retail.

So, how exactly are cybercriminals walking right through the door? Let’s break down the 5 ways identity-based attacks are breaching retailers—and, more importantly, how you can spot (and stop) them before your business is next.

Why Identity-Based Attacks Are Breaking Retail Security

If you picture cybersecurity like a bank vault, most companies have spent years reinforcing the steel doors and locking up the cash registers. But what about the cleaning crew who has a forgotten spare key? Or the IT vendor that still has access, months after their contract ended?

That’s what’s happening in retail. Identity-based attacks exploit the human layer and overlooked digital “keys”—service accounts, SaaS tokens, overprivileged admin roles, and support integrations.

Why does this matter? Because these attacks don’t set off the alarms traditional defenses watch for. Instead, they abuse trust, persistence, and simple human error.

And the consequences? Disrupted operations, lost revenue, regulatory headaches, and worst of all—loss of customer trust.

1. Third-Party Trust Gone Wrong: How Adidas Was Breached

Adidas recently reported a breach that didn’t start from inside its own walls. The culprit? A third-party customer service provider—one that Adidas trusted with sensitive customer data. No malware traces, no evidence of a sophisticated hack. Just a ripple effect from a vendor relationship.

How Do These Attacks Exploit SaaS Identities?

Persistent SaaS Tokens: Vendors receive access for legitimate reasons, but tokens or service accounts often remain active long after the work is done. These rarely require Multi-Factor Authentication (MFA) and often aren’t set to expire.
Unmonitored Access: Old integrations linger, leaving invisible openings for attackers. These overlooked “backdoors” are a classic example of a supply chain compromise.

Security Takeaway:
You’re not just securing your own employees—you’re responsible for every access point, including vendors. SaaS integrations can outlive contracts, and attackers are betting you won’t notice.

Action Steps: – Regularly audit third-party access. – Revoke unused service accounts and tokens. – Enforce strict offboarding for all integrations.

2. Credential Stuffing & Privilege Abuse: The North Face’s Hard Lesson

The North Face has suffered at least four credential-based breaches since 2020—the latest due to credential stuffing. Attackers didn’t hack in; they simply used leaked usernames and passwords (often reused across sites), walked right into customer accounts, and exfiltrated sensitive data. No malware. No phishing. Just basic identity hygiene failures.

How Do These Attacks Unfold in SaaS Apps?

No MFA: Many SaaS logins, especially for customer-facing portals, still don’t have Multi-Factor Authentication.
Silent Entry: With valid credentials, attackers access accounts without triggering endpoint security or behavioral alerts.

Security Takeaway:
Password reuse and lack of MFA are like leaving your store keys under the mat. Attackers prioritize these gaps because they work, again and again.

Action Steps: – Enforce MFA everywhere—especially for privileged and non-human accounts. – Use password monitoring tools to detect credential leaks. – Educate customers and staff on unique password importance.

3. Social Engineering & Help Desk Exploits: Lessons from Marks & Spencer and Co-op

What happens when attackers don’t have (or can’t brute-force) credentials? They create them. UK retailers Marks & Spencer and Co-op were both targeted by the notorious Scattered Spider group, which uses techniques like SIM swapping and social engineering to impersonate employees and manipulate IT help desks.

The result: password resets or MFA bypasses granted to the attacker, giving them legitimate access without ever deploying malware.

How Do These Attacks Work in the SaaS World?

Help Desk Impersonation: Attackers call in, claim to be an employee, and request a password reset (T1556.003).
Bypassing MFA: Through SIM swapping or convincing social engineering, they intercept or reset MFA, defeating a major security control.
Lateral Movement: Once inside, attackers target overprivileged SaaS roles or dormant service accounts to spread quietly.

Security Takeaway:
Identity-first attacks prey on trusted processes and human habits. They blend in, leave little trace, and can grant persistent access.

Action Steps: – Limit help desk privileges and require escalation for sensitive changes. – Isolate support actions; require dual approval for password or MFA resets. – Train support staff on social engineering red flags and verification steps.

4. Overprivileged SaaS Admins: Victoria’s Secret and the Power Problem

Victoria’s Secret delayed earnings after a cyber incident that halted both e-commerce and in-store operations. While details are scarce, the disruption hints at a scenario where SaaS admin credentials (or unchecked roles) gave an attacker—or even an insider—broad control over critical systems.

How Do Overprivileged Identities Expose Retailers?

Stale Admins: Admin and superuser roles are often created for setup or troubleshooting, but rarely reviewed or downgraded.
No Monitoring: Once a role is overprivileged, attackers can wreak havoc from within the SaaS platform—disrupting inventory, order processing, or analytics, without malware or external tools.

Security Takeaway:
A single overpowered account can topple your business operations. Neglecting SaaS role reviews is like handing out master keys and forgetting who has them.

Action Steps: – Conduct regular access reviews for all SaaS platforms. – Apply least-privilege principles—grant only the permissions required. – Continuously monitor for unusual admin behavior or privilege escalation.

5. The Hidden Risks of Customer Support Platforms: Cartier & Dior’s Data Dilemma

Cartier and Dior’s breaches trace back to platforms meant to help customers—third-party SaaS tools for CRM or support. No infrastructure hacks, just attackers leveraging persistent tokens or API keys to access customer data at scale.

Where Do These Risks Hide?

Non-Human Identities: Service accounts, API keys, and machine tokens often fall outside centralized Identity & Access Management (IAM) controls.
Persistent Access: These tokens rarely rotate or expire, so attackers can use them for a long period undetected.

Security Takeaway:
If your SaaS support or CRM platform touches customer data, it’s part of your attack surface. These machine identities—easy to overlook—are prime targets.

Action Steps: – Inventory all SaaS integrations touching sensitive data. – Rotate API keys and tokens regularly. – Bring non-human accounts into your IAM governance and monitoring routines.

Why Most Retailers Miss These Attacks

Let’s pause and ask: Why are these identity-based attacks so effective (and so often missed)?

It’s simple: Security teams are laser-focused on endpoints, firewalls, and infrastructure. But SaaS platforms and the sprawl of identities—human and machine—are often “set and forget.” The result? Blind spots that attackers actively seek out.

SaaS tokens don’t trigger endpoint alarms.
Service accounts aren’t enrolled in MFA.
Help desk processes are optimized for speed, not security.

Attackers know this. They don’t need to break in—they log in and blend in.

The New Security Baseline: Continuous Identity Monitoring

If you take away one thing, let it be this: In today’s retail environment, every identity is a potential breach point—whether it belongs to a person, a vendor, or a machine.

Here’s What Modern Identity Security Looks Like:

Inventory All Identities
Know who (and what) can access your SaaS apps—employees, vendors, service accounts, bots, APIs.
Centralize IAM for SaaS
Bring all identities (human and non-human) under unified governance.
Enforce Least Privilege
Don’t grant more access than necessary, and review privileges regularly.
Monitor for Anomalies
Use tools that alert on unusual behavior—unexpected logins, privilege changes, API calls.
Rotate Credentials and Tokens
Set automatic expiration and rotation policies for all keys, tokens, and passwords.
Train Your People
Especially IT support, on social engineering and verification procedures.

Identity-Driven Breaches: What’s at Stake for Retail?

Let’s get real: The fallout from an identity-based attack extends far beyond IT headaches.

Lost Customer Trust: Shoppers expect you to protect their data. Breaches hurt brand reputation, especially if personal or payment info is involved.
Operational Disruption: Attacks on SaaS platforms can halt inventory, e-commerce, or point-of-sale systems.
Regulatory Fines: GDPR, CCPA, and other privacy laws mean heavy penalties for exposed data—regardless of how it was breached.
Financial Impact: From recovery costs to legal fees and lost sales, the price tag adds up fast.

Here’s why that matters: Even if your tech stack is world-class, a single overlooked identity—a forgotten vendor token, an overprivileged admin, or a duped help desk—can be the weak link.

Proactive Steps: Closing the Identity Gaps in Retail

So, what can retailers do to get ahead of these threats? Here’s a quick checklist to harden your SaaS identity perimeter:

Inventory & Audit: Know every integration, user, and service account in your SaaS stack.
Enforce MFA by Default: Not just for staff, but for vendors and service accounts whenever possible.
Review Permissions: Apply least-privilege and regularly remove unnecessary access.
Monitor Continuously: Invest in solutions that provide real-time visibility and anomaly detection for all identities (see Gartner’s guide to IAM best practices).
Offboard Ruthlessly: When vendors or staff leave, revoke every access point immediately.
Educate Relentlessly: Train every employee—especially IT support—on modern attack tactics.
Govern Machine Identities: Bring API keys, tokens, and service accounts under the same security umbrella as human users.

Final Thoughts: Your SaaS Identities Aren’t Invisible—They’re Unmonitored

As the retail breaches of Adidas, The North Face, Co-op, Marks & Spencer, Victoria’s Secret, Cartier, and Dior have shown, attackers aren’t waiting around for the next big exploit. They’re exploiting what’s already there—misplaced trust, reused credentials, forgotten tokens, and help desk processes that value speed over scrutiny.

Takeaway:
The real threat isn’t invisible. It’s unmonitored. If you’re not watching every identity—human, vendor, or machine—you’re giving attackers room to operate.

Modern retail can’t afford that risk. The good news? With the right tools, processes, and vigilance, you can turn identity into one of your business’s greatest assets—not its weakest link.

FAQ: Identity-Based Retail Attacks

What is an identity-based attack in retail?

An identity-based attack targets digital identities—such as usernames, passwords, tokens, or service accounts—to gain unauthorized access to systems and data. Attackers often “log in” with legitimate credentials, instead of exploiting vulnerabilities or using malware.

Why are identity attacks on the rise in retail?

Retailers use a vast array of SaaS tools, third-party vendors, and customer-facing platforms, each with many identities and integration points. Attackers exploit this sprawl, capitalizing on weak passwords, unmonitored access, and overprivileged roles.

What’s the difference between identity-based attacks and traditional cyberattacks?

Traditional attacks target systems or software vulnerabilities; identity attacks use legitimate credentials or accounts to move through systems undetected, often without triggering security alerts.

How can retailers prevent identity-based breaches?

Regularly audit and inventory all identities (human and non-human)
Enforce MFA for every access point
Review and restrict privileges
Monitor for unusual activity
Train employees on social engineering tactics

Which SaaS accounts are most at risk?

Overprivileged admin roles
Dormant or unused service accounts
Third-party vendor integrations
Customer support and CRM platforms with persistent API keys

What tools or frameworks can help secure SaaS identities?

Look for solutions specializing in SaaS identity security, such as Wing Security, and consult best practices from resources like NIST’s Digital Identity Guidelines.
