The holiday season compresses risk into a short, high-stakes window. Systems run hot, teams run lean, and attackers time automated campaigns for maximum profit. Multiple industry threat reports have found that bot fraud, credential stuffing, and account takeover attempts intensify around peak shopping events, particularly in the weeks around Black Friday and Christmas.
Why peak vacations amplify credential risk
Credential stuffing and password reuse are attractive to attackers because they are scalable. The list of compromised usernames/passwords is automatically tested against retailer login portals and mobile apps, and successful logins unlock stored payment tokens, loyalty balances, and shipping addresses. These are assets that can be quickly monetized. Industry telemetry shows that attackers “pre-stage” attack scripts and configurations days before major sales events to ensure access during peak traffic times.
Retail history also shows how vendor and partner credentials extend the scope of the explosion. The 2013 Target breach remains a classic case. The attackers used stolen credentials from the HVAC vendor to gain network access and install malware on the POS system, leading to large-scale card data theft. This incident is a clear reminder that third-party access must be treated with the same rigor as internal accounts.
Customer Account Security: Password, MFA, and UX Tradeoffs
While retailers can’t afford to add too much friction to their checkout flows, they can’t ignore the fact that most account takeover attempts start with weak, reused, or compromised passwords. Adaptive (conditional) MFA is the best compromise. Prompt for a second factor when a login or transaction is risky (new device, expensive change, unusual location), but keep the general customer journey smooth.
NIST’s digital identity guidance and leading vendor recommendations suggest blocking known compromised credentials, focusing on password length and entropy rather than outdated complexity rules, and moving to phish-resistant passwordless options such as passkeys when possible.
Being careful about staff and third party access can reduce operational blast radius. Employee and partner accounts often have higher privileges than customer accounts. Management consoles, POS backends, vendor portals, and remote access all require mandatory MFA and strict access controls. Use SSO with conditional MFA to protect high-risk actions while reducing the burden on legitimate staff and requiring privileged credentials to be unique and stored in a vault or PAM system.
Incidents that demonstrate risk
Target (2013): Attackers used stolen vendor credentials to infiltrate networks and deploy point-of-sale malware, demonstrating how third-party access can enable widespread compromise. Boots (2020): Boots temporarily suspended Advantage card payments after attackers attempted logins by reusing credentials from other breaches, impacting approximately 150,000 customer accounts and forcing operational action to protect loyalty balances. Zoetop / SHEIN (Investigation and Settlement): The New York State Attorney General finds that Zoetop was inadequate in its response to a large-scale credential breach, resulting in enforcement actions and fines. This is an example of how poor breach response and weak password handling can amplify risk.
Technical controls to prevent credential abuse at scale
Peak season requires layered defenses that thwart automated exploits without causing friction for real users.
Bot management and device behavior fingerprinting to separate human shoppers from scripted attacks. Rate limiting and gradual challenge escalation slow down credential testing campaigns. Credential stuffing detection that flags behavioral patterns, not just volume. Block known malicious sources with IP reputation and threat intelligence. Use invisible or risk-based challenge flows instead of aggressive CAPTCHAs that hurt conversions.
Industry reports repeatedly point to bot automation and “preconfigured” attack configurations as key drivers of holiday fraud, so investing in these controls before peak weeks pays off.
Continuity of Operations: Test before failover is required
Authentication providers and SMS routes may fail. And doing so during peak trading hours can result in lost revenue and long lines. Retailers should test and document failover procedures.
Pre-approved emergency access via short-lived, auditable credentials in a secure vault. Manually validate in-store or phone purchase workflows. Tabletop exercises and load tests including MFA and SSO failover.
These steps not only protect your data, but also your revenue.
Where Specops password policies can help
Specops password policies address several high-impact controls that retailers need before peak weeks.
Block common compromised passwords by checking reset and new passwords against a known compromised dataset. Continuously scans Active Directory against a database of over 4.5 billion compromised passwords and enforces user-friendly rules (passphrases, pattern blocklists) that improve security without adding help desk overhead. Integrate with Active Directory to quickly apply across POS, management systems, and backend systems. By providing operational telemetry, you can spot risky password patterns and ATO attempts early.
