Every year, Black Friday kicks off the most profitable — and the most dangerous — season for online merchants. While sales spike dramatically, so do fraud attempts. For high-risk merchants, the combination of increased traffic, faster checkouts, aggressive discounts and global buyers creates the perfect environment for Black Friday fraud to escalate.
From account takeovers to card testing, friendly fraud and January’s wave of chargebacks, the risks are higher than ever. And with consumer spending shifting toward frictionless digital payments, fraudsters continue to exploit vulnerable systems, overstressed teams and poorly optimized payment flows.
In this guide, we break down why Black Friday fraud is rising, which attack patterns merchants must watch for, and how high-risk businesses in Europe can protect revenue with smarter payment strategies.
Black Friday and Cyber Monday bring three dynamics that fraudsters love:
high volume, high speed and high emotion. When customers rush through checkout, commit to limited-time offers or buy from brands they’ve never interacted with, criminals take advantage of the chaos.
Below are the core reasons Black Friday fraud grows faster than sales:
Fraudsters use busy periods to blend in. Card testing, bot-driven attacks and repeat attempts are harder to spot when servers and payment gateways are overloaded.
Merchants reduce friction to increase conversions. But fewer authentication steps leave the door open for unauthorized transactions.
Black Friday attracts first-time buyers, making it difficult to distinguish between legitimate high-volume traffic and risky profiles.
Q4 is the peak season for accounts bought on the dark web — perfect timing for account takeovers and credential-stuffing attacks.
Many Black Friday purchases become friendly fraud after the holidays:
For high-risk industries, these patterns push ratios dangerously close to thresholds.
Understanding the attack patterns is the first step to building better defense systems. These are the top fraud strategies targeting merchants during Black Friday and Cyber Monday.
Fraudsters use stolen card numbers and run dozens of micro-transactions to identify which cards are still active. High-risk merchants are frequent targets because approvals tend to be more flexible across geos.
Once criminals gain access to a customer account, they update delivery addresses, add new cards or place high-value orders immediately.
Customers dispute legitimate transactions due to regret, forgetfulness, or dissatisfaction. Black Friday deals lead to significantly higher January chargebacks.
Promo code exploitation, refund fraud and return abuse spike during and after Black Friday.
High-risk merchants selling globally must manage risk coming from unfamiliar regions, new BIN ranges and higher bot activity.
Industries such as nutraceuticals, CBD, gambling, trading platforms, subscription businesses, adult content, ticketing, crypto and digital products face uniquely high exposure during Q4.
Reasons include:
For these merchants, a standard fraud tool is not enough — they need specialized high-risk fraud prevention and smarter payment routing.
Below are actionable strategies to reduce fraud, prevent chargebacks and protect revenue during Q4.
Static rules often block good customers during peak sales.
Dynamic risk scoring analyzes:
This dramatically reduces false declines while stopping real fraud.

Benefits during Black Friday:
For high-risk merchants, this can mean 6–12% more approved sales during peak hours.
