TL;DR: Holiday shopping seasons amplify credential stuffing, password reuse, and infostealer-driven account takeover across retailers, payment processors, logistics firms, and their partners, according to Enzoic. Static password rules and periodic resets cannot keep pace with real-time credential abuse; continuous credential monitoring closes the exposure window instead of just enforcing policy.

Questions worth separating out
Q: What breaks when organisations rely on password complexity alone against credential stuffing?
A: Password complexity does not stop attackers who already possess valid usernames and passwords from prior breaches.
Q: Why do seasonal traffic spikes make compromised credentials more dangerous?
A: Peak traffic gives attackers cover because fraudulent logins blend into normal shopping volume and teams are less likely to spot anomalies quickly.
Q: How can security teams tell whether breached-password controls are working?
A: Look for two signals: blocked sign-ins from credentials found in breach data and a shrinking time gap between exposure discovery and enforcement.
Practitioner guidance
- Implement breached-password screening at authentication time Reject credentials that appear in known breach datasets before a session is issued, and pair that check with user messaging that explains why the login was blocked.
- Monitor session artifacts as credentials Treat browser-stored secrets, refresh tokens, and session cookies as high-value identity assets, then invalidate them when endpoint compromise or anomalous reuse is detected.
- Map partner login paths to shared blast radius Identify which external vendors, payment processors, and logistics providers can pivot from one credential compromise into your core systems, then prioritise those access paths for stricter validation.

Enzoic's full blog post covers the operational detail this post intentionally leaves for the source:
- How continuous password protection is wired into authentication flows to block exposed credentials in real time.
- The specific ways infostealer malware and credential stuffing create attack paths across retail, payments, logistics, and vendor ecosystems.
- Why seasonal change freezes and holiday traffic make exposure windows harder to spot and slower to close.
- How compliance expectations map to proactive credential hygiene in modern identity programmes.

Holiday traffic creates a credential blast radius that most password programmes still under-estimate: the problem is no longer whether one password is strong enough, but how quickly stolen credentials can be replayed across retailers, processors, and vendors during peak demand. Password policy and periodic resets do not change the fact that reused credentials arrive as legitimate authentication events. Practitioners should treat exposure as an ecosystem property, not a single-account issue.
A few things that frame the scale:
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, according to The State of Non-Human Identity Security.
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, according to The State of Non-Human Identity Security.
A question worth separating out:
Q: Should organisations prioritise MFA or compromised-credential screening first?
A: Both matter, but compromised-credential screening usually closes a more direct path to account takeover because it stops the login before a session is created. MFA still reduces risk, especially against phishing and password reuse, but it does not solve the problem of credentials already circulating in criminal markets. The strongest posture combines screening, MFA, and session monitoring.
