The holiday sales data is in! As anticipated, bad bot activity ramped up around the Black Friday and Cyber Monday sales events again this year.
Through processing over 6.8 billion requests, Kasada observed a 23% increase in bad bot traffic in the week before Thanksgiving and a 50% increase during Black Friday week as shown in our 2022 Holiday Bad Bot Report.

KasadaIQ analyst commentary on the threat environment
Figure 1: Kasada Threat Intelligence observed an increase in bad bot activity leading up to Black Friday, with most malicious bot traffic originating from the United States.
Kasada’s Threat Intelligence team identified four major cyber threats to retailers this holiday shopping season. Our data reveals an increase in scraping attacks, Freebie Bots, fake account creation, and gift card fraud. Bot operators frequently used open-source dev tools, spoofed browser platforms, and headless browsers to perform their attacks at scale.
As predicted in our Holiday Preparedness Blog, scraping was the most prevalent automated threat Kasada observed leading up to Black Friday. Over 3 million scraping requests per day during peak times represents a staggering 43% increase as compared to October.
Many consumers started their holiday shopping early again this year. Subsequently, with more retailers competing for business and starting “Black Friday” sales events as early as October, scraping bots soon followed to capture retail data.
Rather than target specific product pages, bots indexed entire websites, leading us to believe their goal was to monitor stock and price changes for arbitrage.
Web scraping is difficult for retailers to detect. As such, there has been a long-running legal battle in the U.S. to determine scraping’s legality. Earlier this year, the U.S. Ninth Circuit Court of Appeals reaffirmed its decision that scraping data is legal and does not violate the Computer Fraud and Abuse Act.
However, scraping certainly creates privacy concerns for online businesses and is also a popular method used by competitors to perform arbitrage and cybercriminals to create counterfeit websites.
Most painfully to shoppers, scrapers are a common reason why websites suffer slow web speeds and degraded site performance. Around the holidays, this is particularly troublesome for retailers since conversion rates are on the line and websites are already inundated with higher traffic to their sites.

Time and time again we say, “where there’s a profit to be made, the bots will follow.” Like bees attracted to honey, Freebie Bots were drawn to Black Friday and Cyber Monday deals to get items for a fraction of the price and then resell them for a profit. Products with the highest discounts (70%-100% off) offered botters the best profit margin and were subsequently the most desirable. Items purchased by Freebie Bots typically weren’t high-value items or in high demand, but rather ordinary consumer products such as LED strips and dog collars.
We estimate that Freebie Bots successfully purchased over 40,000 products during Cyber 5 week (11/17 to 11/29), totaling over $1.1M in retail value for a small price of $134. One bot targeting a single retailer was solely responsible for obtaining over $500,000 worth of goods (over 20,000 products) that cost the bot operators only $85.
In the weeks leading up to Black Friday, bot checkouts steadily increased daily, with spikes occurring at 12:00 am PST on Thanksgiving and Black Friday. Data suggests retailers have products scheduled to go live at midnight and as soon as the product becomes available, Freebie Bots were ready to quickly identify pricing and checkout.

In the days leading up to Black Friday last year, Kasada detected bots attempting to create over 25,000 accounts a day for a single retailer. This year, Kasada’s Threat Intelligence team observed a similar trend. Large amounts of new accounts were being generated a week before Black Friday and on Cyber Monday. New accounts are typically created by bad actors using free email providers like iCloud and Gmail to create fake accounts and circumvent inventory checks during checkout.
A 3x increase in fake account creation before Black Friday suggests that adversaries were preparing for holiday sales and hype drops by aging fake accounts. Bot operators “age” accounts by creating fake user accounts days before the sale starts. This helps bot operators avoid detection and increases the likelihood that their account won’t be flagged during a drop. Aged accounts could then be used for personal gain or sold to other parties for future use.
From Black Friday to Cyber Monday, the number of fake accounts generated rose by 40%. We suspect fake accounts were being used to commit new account fraud, abusing sign-up promotions offered by retailers to obtain new customers and boost sales. Promotions often include coupons or free items when you create an account. The better the incentive, the more likely bots are to abuse it and create massive volumes of new accounts to claim the incentive.

According to the National Retail Federation, holiday gift card spending is expected to reach $28.6B this year.
Throughout the holidays, fraudsters regularly check balances by performing automated gift card lookups. Kasada has observed a 6x increase in gift card lookups in the span of a few hours during weekend holiday shopping in November. Last year, gift card lookups quadrupled in bot requests which was an early warning sign and a key indicator that fraudsters were using bots to identify and steal gift card balances.
