Black Friday is supposed to be the most exciting shopping day of the year – brands slash prices, customers fill up carts, and digital sales dashboards glow green. But that’s only half the story. There’s another group lined up at the digital door before shoppers even wake up: bot attacks, sneaking in before real customers arrive. According to Adobe’s 2024 Digital Shopping Report, Black Friday online spending exceeded $9.8 billion in the U.S., but an estimated 52% of all traffic to retail sites during peak hours was non-human automation.
These bots do not wait in queues. They don’t compare products. They don’t hesitate or rethink their purchase. They act within milliseconds, and they aren’t there to shop like everyone else – they are there to exploit.
If you work in cybersecurity, retail tech, or e-commerce, you already know the holiday season attracts heavy traffic. The bigger question is: why do bot attacks surge so aggressively on Black Friday, and what can your defense team do without slowing real customers down? Let’s break it down in a practical, human way – because security works best when we understand both the technology and the intent behind it.
How Bot Attacks Work on Black Friday
Before deep-diving into the surge, let’s keep definitions clear. A bot attack refers to automated traffic targeting an e-commerce environment with the goal of:
- Jumping ahead of human shoppers,
- grabbing limited products for resale,
- scraping pricing and inventory data,
- stealing customer accounts,
- committing fraud at checkout,
- Or disrupting the shopping experience itself.
These are not the “good bots” that index websites for search engines. These are precision-engineered automation scripts, often rented from marketplaces or botnet operators. A Deloitte analysis revealed that e-commerce sites experience 3×-8× more bot activity during seasonal sales compared to non-promotional months, making holiday shopping the highest-risk cyber window of the year.
And on Black Friday, their trigger finger gets very itchy.
Why Bot Attacks Surge On Black Friday
1. High volume gives bots the perfect camouflage
A holiday sale generates enormous traffic. Bots love this. The more real visitors you get, the easier it becomes for malicious traffic to blend in.
Recent research showed that during the 2024 holiday season, 57% of all traffic to retail websites came from bots, and 71% of that traffic was confirmed malicious. Cloudflare recorded a 76% surge in automated bot traffic during Black Friday weekend 2024, with peak activity occurring between 12:00 a.m. and 3:00 a.m., before human shoppers arrived online.
Another Black Friday data point reported 112,000 price-scraping attempts in a single day, more than triple a typical daily rate.
Think of a crowded airport. It’s harder to monitor every passenger when everyone is rushing. The same happens online.
2. Limited-stock, high-value products are magnets
Bots don’t target items randomly. They chase the products that sell fastest and profit most on resale platforms.
One report noted that in the lead-up to Black Friday, attack levels rose 5–10× higher than normal for high-demand items like consoles, sneakers, and premium electronics.
And fake account creation explodes, too. Platforms recorded 613,000 fake registrations two days before Black Friday – used for checkout manipulation and account-based fraud.
Limited inventory + high user demand = ideal hunting ground for automated fraud.
3. Bots now behave almost like real users
A few years ago, bot detection relied on spotting outdated browsers, strange user-agents, or repeated requests. That’s no longer enough.
Today’s bots simulate human browsing patterns, rotate IPs, mimic mouse movements, copy real purchase timing, and route traffic through residential IPs. Agentic AI attacks involve autonomous AI systems that plan, adapt, and execute cyber actions without continuous human control, dynamically probing defenses, scaling attacks, and adjusting strategies in real time. Gartner projects a dramatic shift in application design, with enterprise apps embedding task-focused AI agents jumping from below 5% in 2025 to 40% by 2026.
A recent modelling study even showed holiday shopping days correlated with significantly more severe cyberattacks, proving that attackers take advantage of seasonal peaks.
So the threat isn’t just bigger – it’s smarter.
Human Example: What a Bot Attack Looks Like in Real Life
Picture a retailer launching a limited-stock TV discount at midnight. Within seconds:
- Hundreds of new accounts registered,
- Carts fill with identical models,
- Stock availability drops to zero,
- And angry legitimate users refresh endlessly.
But no orders are complete. IBM’s Cost of Cybercrime Report 2024 notes that inventory denial and cart-hoarding bots caused an average revenue loss of $4.88 million for mid-to-large online retailers, up from $3.2 million in previous years.
This is a cart-hoarding attack. Bots grab inventory in the cart and wait – blocking real shoppers and manipulating supply visibility. One intelligence report recorded 130,000 such cart-abandonment attacks on Black Friday.
To the business, this looks like “high interest.” But it’s actually an automated disruption.
How To Fight Back – Without Slowing Real Customers
Here’s the reassuring part: bots are not unstoppable. With the right layered strategy, retailers can contain and discourage them. Think of defence like an onion – not a wall. Each layer removes opportunities for exploitation. Modern retail teams are pairing cybersecurity tools with AI-driven customer support to keep shoppers engaged while malicious traffic is filtered out in the background. AI chatbots now support shoppers in real time, answering product questions, reducing wait times, and guiding purchases – helping retailers keep genuine customers engaged while security systems quietly filter out bots.
1. Start at the ingress – filter suspicious traffic
Good first-line techniques include:
- Rate-limiting repeated requests,
- IP reputation checks,
- geolocation validation,
- device fingerprinting,
- And proxy/VPN challenge responses.
But stop short of relying only on this. Sophisticated bots can route through clean IPs and residential proxies. This is baseline – not a victory lap.
2. Use behavioural analytics – not just signatures
Bots may look human-like in surface data. But behaviour rarely lies.
Signals that behavioural systems should watch:
| Behavior signal | Potential attack hint |
|---|---|
| Multiple new accounts created within seconds | Fake registration bot |
| Carts are filled and then abandoned repeatedly | Cart-hoarding |
| Logins from many accounts using the same device/IP pattern | Credential stuffing |
| Checkout attempts with multiple cards in a short time | Payment fraud |
| Sudden interaction with only high-value items | Data scrapers or resellers |
If defence teams spot behavioural inconsistencies early, containment becomes smoother.
3. Strengthen the three most attacked flows
Bots love these:
- Registration
- Login
- Checkout
Security leaders should:
- Add invisible bot challenges for suspicious sessions,
- Apply dynamic MFA to unknown devices,
- Enforce velocity checks on cart actions,
- And protect API endpoints, especially for mobile apps.
One global cyber intelligence report highlighted that API attacks were a favourite vector in 2024 holiday attacks.
4. Monitor your inventory like a security asset
Inventory is money. Protect it like a bank vault.
Recommended measures:
- Place minimal cart-hold time limits.
- Add “fair queueing” to the limited items.
- Alert when inventory velocity deviates from normal.
- Hide total stock levels from public view.
A user shouldn’t be able to hoard 35 PlayStations at 12:01 AM – no matter how lucky they are.
5. After Black Friday: don’t dismantle your defenses
The holiday-attack pattern is seasonal. So review logs, attack signatures, IP patterns, and account creation anomalies to fine-tune the next event, like Cyber Monday or Christmas.
Bots evolve. Security evolves, too. Successful teams treat each attack as intelligence for the next one.
A Human Message for Tech Leaders and Security Teams:
Black Friday security isn’t only about systems – it’s about trust. When bots block shoppers, the damage is more than lost revenue. Customers remember frustration, but they also remember smooth checkout. Protection done right drives growth, not friction.
Final Takeaway
Bot attacks surge on Black Friday because demand spikes, inventory is limited, and heavy traffic hides malicious activity while automation grows more advanced. The answer isn’t harsh blocking – it’s smart, layered protection built around real shopping behaviour. With the right preparation, retailers can serve genuine customers and stop automated threats at the same time, without slowing the buying experience.
Conclusion
Bot attacks surge on Black Friday because of high demand, limited inventory, and the perfect cover of heavy web traffic- but they’re not unstoppable. With layered protection, behavioural analytics, and secure checkout flows, retailers can keep both shoppers and revenue safe. The brands that prepare early deliver not only sales, but trust- and that advantage lasts far beyond Black Friday.
FAQs
1. Why do bots target Black Friday more than normal days?
Because the high traffic helps them hide, and limited-stock promotions make resale profitable. Bots automate purchasing and account takeover at a scale that humans cannot match.
2. What are the top bot threats during Black Friday?
The most common ones include price scraping, credential stuffing, cart hoarding, fake registration, fraud during checkout, and inventory denial.
3. Can small retailers be targeted too?
Yes. Attackers often automate attacks across thousands of stores. Bots do not “choose brands” – they choose money. Smaller stores with weak controls can be even more attractive.
4. Will security controls slow my real customers down?
Not if implemented correctly. Modern bot-management tools use invisible challenges and behavioural monitoring rather than intrusive CAPTCHA or friction.
5. What is the fastest improvement a retailer can apply before Black Friday?
Secure the registration, login, and checkout flows first. That’s where most automation hits during high-demand shopping events.
