# Black Friday DDoS: Why Retailers Are Under Attack During Peak Traffic

> Black Friday isn't just your biggest sales day — it's the day attackers know the cost of downtime is highest. Preparation before the day is the only effective defense.

Every year the weeks around Black Friday bring a measurable rise in DDoS attacks against e-commerce, logistics and payment infrastructure. The reason is simple and cynical: the more a retailer stands to earn in a given hour, the more it stands to lose if that hour is disrupted — and the more leverage that hands an extortionist or a competitor. The busiest shopping day of the year is also the day an attack is worth the most.

## Who Attacks Retailers, and Why

- Extortionists demand payment in exchange for not attacking during peak hours, betting that the cost of downtime dwarfs the ransom.
- Unscrupulous competitors try to knock a rival offline to redirect shoppers during the window that matters most.
- Hacktivists target brands with controversial supply chains or policies while attention is highest.
- Opportunists: with booter services renting flood capacity for the price of a meal, anyone with a grudge can try.

## Why Peak Traffic Makes Defence Harder

Black Friday is uniquely difficult because your legitimate traffic is already spiking. The usual signal that something is wrong — a sudden surge — is exactly what you expect on the day. An attack can hide inside a genuine rush, and defences tuned for normal load may either miss it or, worse, throttle real shoppers. This is why baselines and preparation matter far more than a same-day reaction.

## A Four-Week Preparation Timeline

- Four weeks out: confirm DDoS protection is active and traffic is genuinely routing through it — not just configured but live.
- Two weeks out: run a load test and record your baseline traffic profile, so a real anomaly stands out against the expected rush.
- One week out: verify your origin IP is not exposed anywhere, and check every subdomain and staging host that might leak it.
- Three days out: brief the on-call team, update the incident runbook, and confirm everyone can reach the dashboard and act.
- Day of: set real-time alert thresholds relative to the day's expected peak, not an ordinary day's, so you are not blind or drowning in false alarms.

> **The worst time to start is during the attack** — Protection put in place on the morning of Black Friday is protection that is not ready. DNS changes take time to propagate, and tuning happens under fire. Configure it weeks ahead so the day itself is uneventful.

## How Akarguard Helps Through Peak Season

Routed through Akarguard's reverse-proxy edge, your store's traffic is filtered before it reaches your origin, and automatic mitigation raises protection the moment an attack is detected — without a human needing to notice during the busiest hours. Your origin IP stays hidden so it cannot be hit directly, per-endpoint rate limits protect cart and checkout from abuse, and each incident produces a report you can review afterwards. Set it up in the calm weeks beforehand and the day itself should feel like any other busy day.
