The holiday season brings with it a host of cybersecurity risks . Systems are running at peak capacity, teams are stretched thin, and attackers are running automated campaigns to achieve maximum performance. Multiple industry threat reports show that bot-based fraud , attacks credential stuffing , and account takeover attempts intensify around peak shopping events, especially in the weeks surrounding Black Friday and Christmas .
Credential stuffing and password reuse are attractive to attackers: lists of exposed usernames/passwords are automatically tested on retail login portals and mobile apps. Successful logins “unlock” stored payment tokens, loyalty balances, and shipping addresses. These are assets that can be instantly converted into cash.

Industry telemetry shows that adversaries are “preparing” attack scenarios in the days before major sales to secure access during peak traffic.
The history of retail also shows how vendor or partner credentials extend the “blast radius.” Target remains a classic case: attackers used credentials, stolen from an HVAC supplier, to gain network access and install malware on POS systems, which enabled large-scale card data theft.
This incident is a clear reminder that third-party access should be treated with the same rigor as internal accounts.
Account Security: Passwords, MFA, and UX Tradeoffs
Retailers can’t allow too much friction in checkout flows, but they also can’t ignore the fact that attempts account takeover start with weak, reused, or compromised passwords. Strong passwords and the use of MFA are essential protections.

NIST digital identity guidelines and recommendations from major vendors suggest blocking known compromised credentials and moving to passwordless (phishing-resistant) options such as passkeys where feasible.
Staff and third-party partners also play a significant role in customer security during the holiday season. Employee and partner accounts often have more authority than customer accounts. Admin consoles, POS backends, vendor portals, and remote access require MFA security and strict access controls.
Cybersecurity: Incidents that illustrate the risk include:
– Target (2013): Attackers used stolen vendor credentials to infiltrate the network and deploy POS malware, showing how third-party access can enable widespread breach.
– Boots (2020): Boots temporarily suspended Advantage Card payments after attackers reused credentials from other breaches to attempt logins, affecting around 150,000 customer accounts.
– Zoetop / SHEIN: The New York Attorney General found that Zoetop inadequately handled a major credential breach, leading to enforcement actions and fines, an example of how poor breach response and weak password management increase risk.
The peak season requires multi-layered defenses that stop automated abuse without causing problems for users:

– Manage bots and device-behavior fingerprints to separate real buyers from automated attacks.
– Rate limits and progressive challenge escalation to slow down credential testing campaigns.
– Credential stuffing detection that signals behavioral patterns, not just volume.
– IP reputation and threat intelligence to block known malicious sources.
– Invisible or risk-based challenge flows instead of aggressive CAPTCHAs.
Security researchers repeatedly point to bot automation and “prepared” attack configurations as major drivers of fraud during the holiday season, so investing in these defenses is critical.

Cybersecurity and Business Continuity
. Authentication and SMS routes providers can fail. And if this happens during peak transaction times, the result can be lost revenue and long queues Retailers should test and document failover procedures:
- Pre-approved emergency access via short-lived, auditable credentials in a secure vault.
- Manual verification workflows for in-store or phone purchases.
- Tabletop exercises and load testing that include MFA and SSO failovers.
These steps protect revenue as well as data.
