As major retailers and auto giants fall victim to third-party breaches, the cybersecurity landscape shifts from software exploits to identity theft and vendor compromise.
The fragility of the global digital supply chain was exposed yet again this week as Ahold Delhaize, the retail conglomerate behind major U.S. brands like Food Lion and Stop & Shop, confirmed a significant cyberattack compromising the data of millions. Reported on November 25, 2025, this latest incident serves as a stark coda to a tumultuous 18 months in cybersecurity, joining a growing list of corporate giants-including Volkswagen, Ticketmaster, and Fidelity-who have found their fortress walls breached not by direct assault, but through the side doors of third-party vendors and compromised credentials.
This wave of breaches highlights a critical evolution in threat tactics. While previous years were defined by technical zero-day exploits in software like MOVEit, 2024 and 2025 have seen a pivot toward identity-based attacks and deep supply chain infiltration. As organizations harden their internal perimeters, attackers are increasingly targeting the soft underbelly of the enterprise ecosystem: the service providers and legacy accounts that connect the global economy.

The Ahold Delhaize incident is not an isolated event but part of a calculated pattern. According to reports from PKWARE, the attack on the food retail giant compromised millions of records, echoing the scale of massive data exfiltration events seen earlier in the year.
Just months prior, in April 2025, details emerged regarding a breach at Volkswagen. While the automaker's core IT systems remained unaffected, sensitive data was stolen via a supplier or subsidiary, with the ransomware group 8Base claiming responsibility. 8Base, known for its "double-extortion" tactics-encrypting data while simultaneously threatening to leak it-had reportedly held the information since September 2024 before making it public.
"The breach was orchestrated by hackers associated with the Scattered Spider group, who exploited compromised credentials of a Snowflake employee account. This unauthorised access led to the exfiltration of vast amounts of sensitive data." - CM Alliance on the Ticketmaster Incident
This "vendor-hop" tactic was most visibly demonstrated in the colossal Ticketmaster breach of May 2024. In that instance, the hacking group ShinyHunters bypassed Ticketmaster's direct defenses entirely, instead stealing login details for a Snowflake cloud storage account. The result was catastrophic: over 560 million customer records, including order history and payment information, were leaked online. The method was deceptively simple-no sophisticated code was required, just valid credentials that lacked sufficient multi-factor authentication (MFA).
The shift from software vulnerabilities to identity compromise is reshaping defense strategies. The 2025 Data Breach Investigations Report from Verizon notes that incidents analyzed for the year took place between late 2023 and late 2024, confirming a sustained trend of credential exploitation. Microsoft also reported that breaches often begin with "legacy" accounts lacking MFA, a vulnerability that allowed hackers to maintain access to systems for months before detection.
The Infosys McCamish Systems breach, which impacted Fidelity, further illustrates the opacity of third-party risk. Though the initial attack occurred in late October 2023, the full scope of the fallout-including the compromise of sensitive customer data like Social Security numbers-continued to ripple through 2024 and 2025. This delay between infection and discovery, often referred to as "dwell time," is becoming a hallmark of modern breaches. In an extreme example, reports indicate that Toyota exposed data from February 2015 to May 2023, a staggering eight-year window of vulnerability.
The cumulative effect of these breaches is a profound erosion of consumer trust and a forced re-evaluation of corporate liability. Regulatory bodies are intensifying their scrutiny of how enterprises manage their vendors. The narrative is shifting from "we were hacked" to "we failed to audit our partners."
For businesses, the financial toll is escalating beyond ransom payments. UpGuard reports that the fallout from the MOVEit vulnerability alone had exceeded $15 billion in total damages by early 2024. With groups like 8Base and ShinyHunters industrializing the extortion process, security budgets for 2026 are being aggressively reallocated toward Identity and Access Management (IAM) and third-party risk management platforms.
As we move toward 2026, the lesson from Ahold Delhaize, Ticketmaster, and Volkswagen is clear: the perimeter is dead. Security can no longer stop at the company firewall. The future of enterprise defense lies in "Zero Trust" architectures that assume every user and every vendor is potentially compromised. Until organizations can achieve real-time visibility into their entire digital supply chain, the headlines of 2025 are likely to repeat themselves.
