Executive Summary

Bot attack statistics in 2026 show that automated abuse has moved beyond simple crawler traffic. The current risk is concentrated around bad bot traffic, credential stuffing, account takeover, scraping, API abuse, fake account creation, checkout manipulation, and DDoS botnets. This guide separates bot-specific figures from fraud-wide, DDoS-wide, API-wide, and cross-industry statistics so security, fraud, product, and executive teams can use the numbers without overstating their scope.

Top Bot Attack Statistics for 2026

Use this summary as a fast editorial overview. Each figure should still be checked against the original source before publication, especially when the source is based on vendor telemetry rather than a universal internet dataset.

Quick answer: What do bot attack statistics show?

Bot attack statistics show that the main risk is not “bots” in the abstract. It is abusive automation concentrated around login flows, credential stuffing, account takeover, scraping, API abuse, fake account creation, checkout manipulation, inventory hoarding, and DDoS botnets. The strongest 2025–2026 datasets also show that proxy networks, residential IP abuse, and AI-driven crawlers complicate the boundary between benign and malicious automation. For security, fraud, and product leaders, the practical implication is clear: traffic classification alone is insufficient. High-value workflows, APIs, authentication paths, and abuse cases need direct validation, monitoring, and safely scoped testing.

Why Bot Attack Statistics Matter

Bot attack statistics matter because automated abuse is not measured the same way as malware, ransomware, or generic breach counts. OWASP’s Automated Threats project explicitly frames these events as abuse of inherent application functionality through automated actions, including credential stuffing, account creation, scraping, spamming, scalping, and denial of inventory. That is a different risk model from classic vulnerability exploitation, even when both occur in the same environment.

They also matter because the operational blast radius reaches several teams at once. Login abuse hits security and fraud. Scraping hits product, data, content, and revenue teams. Inventory denial and scalping hit ecommerce and customer experience. API abuse hits AppSec and engineering. DDoS botnets hit infrastructure and availability. Thales, Imperva, Akamai, and Cloudflare all show that the most abused surfaces are the ones closest to authentication, business logic, financial transactions, and APIs.

Bot attack statistics also force a distinction between good bots and bad bots. Search crawlers, monitoring tools, and other approved automation are part of normal internet traffic. Thales and Imperva both publish separate human, good bot, and bad bot shares because collapsing them into one “bot traffic” bucket hides the actual security problem.

Finally, statistics only become useful when tied to control decisions. Data that says bots are a majority of traffic is interesting. Data that shows API-directed abuse, login abuse, identity attacks, payment abuse, and botnet-driven DDoS converging on the same critical paths is actionable. That is the level security buyers need for prioritization.

Methodology and Verification

Methodology: How We Selected and Verified the Statistics

This article prioritizes original reports, official threat intelligence publications, standards projects, and public-sector alerts over third-party statistic roundups. Public-sector and standards sources such as the FBI and OWASP are used for definitions, fraud context, and classification. Vendor telemetry from Thales/Imperva, Cloudflare, Akamai, NETSCOUT, F5, HUMAN, DataDome, LexisNexis Risk Solutions, Sift, and Pixalate is used where those vendors clearly describe what they measured and over what period.

Recency matters, but freshness alone is not enough. A 2026 report based on 2025 telemetry is generally better than a 2024 report, but older data is still useful when it provides historical comparison or when the latest source does not publish an equivalent metric. That is why this guide uses the 2026 Thales findings alongside the 2025 Imperva report and selected 2025–2026 API, DDoS, fraud, and AI traffic datasets.

Definitions are treated carefully. “Bot traffic,” “bad bots,” “OWASP automated threats,” “ATO,” “API attacks,” “DDoS,” “invalid traffic,” and “fraud” are not interchangeable categories. For example, Pixalate’s invalid-traffic work is useful in ad-fraud sections, but even Pixalate notes that IVT is a measurement category that can include non-human traffic and other non-legitimate impressions rather than a pure count of malicious bots.

Vendor caveats are surfaced rather than hidden. F5’s report focuses on traffic seen after bot mitigation is already deployed, so its login percentages are not global internet baselines; they are useful for understanding persistent malicious automation against protected environments. DataDome’s report is a testing study of nearly 17,000 websites, so its “2.8% fully protected” figure is an exposure benchmark, not a market share estimate of successful bot attacks.

Threat Landscape and Statistics

Bot Attack Threat Landscape in 2026

The current threat landscape is defined by convergence. Bot abuse no longer sits in a single bucket called “bad bot traffic.” The same organizations now face credential stuffing on web and mobile login flows, scraping on public-facing content and pricing endpoints, API abuse on transactional services, fake account creation on registration paths, carding and payment abuse on checkout flows, and DDoS pressure on the infrastructure that keeps these services reachable. OWASP’s automated-threat taxonomy maps this convergence directly to account creation, credential stuffing, scraping, spamming, scalping, denial of inventory, and denial of service.

AI changed the economics rather than the categories. Thales says AI-enabled bot attacks increased 12.5x year over year, HUMAN says AI-driven traffic grew 187% in 2025, and Akamai notes that agentic AI amplifies API risk instead of creating an entirely separate attack domain. The practical effect is more automation, better mimicry, and more noise around intent.

Residential proxies, browser impersonation, headless automation, and mitigation bypass remain central. Imperva found 21% of ISP-based bot attacks used residential proxies, while Thales says 41% of bot attacks used Chrome to appear legitimate. Kasada and F5 both show attackers retooling around defenses rather than giving up, especially around high-value login and commerce flows.

Bad Bot Traffic and Automated Abuse Statistics

The strongest current public bot-traffic baseline is Thales’ 2026 report, which says bots accounted for 53% of internet traffic in 2025 and bad bots for 40%. The prior Imperva report, covering 2024, found 51% automated traffic, 37% bad bots, and 14% good bots. That direction of travel is more important than any single absolute value: automation is large, persistent, and increasingly shaped by AI-assisted tooling.

Sophistication is mixed, not uniformly advanced. Thales says simple bot attacks were 42% of bot attacks in 2025, and Imperva’s 2025 report found simple bots were 45% of all bot attacks in 2024 while moderate and advanced attacks together were 55%. That suggests two simultaneous problems: advanced evasion for high-value abuse, and cheaper large-scale automation enabled by easier tools.

Bad bot traffic should not be presented as “all bots are malicious.” Good bots remain material. But neither should security leaders dismiss this as crawler noise. Imperva says 31% of all attacks it recorded and mitigated were OWASP automated threats, which means automation is already showing up in attack telemetry, not only in web analytics.

Account Takeover and Credential Stuffing Statistics

Credential stuffing remains one of the clearest examples of bot-enabled abuse because the attack itself is defined as mass login attempts using exposed username-password pairs. OWASP lists credential stuffing as OAT-008, and Akamai defines it as automated use of stolen credentials to commit account takeover.

Imperva reported ATO attacks increased 40% from 2023 to 2024 and 54% since 2022. F5 adds useful operational context: even with bot mitigation in place, malicious login attempts still averaged 10.6% of web authentication traffic and 5.2% of mobile API authentication traffic, with Technology reaching 33.5% of web authentication traffic and Entertainment and eCommerce mobile APIs both exceeding 23%.

Kasada’s 2025 report offers a concentrated threat-intelligence view rather than an internet-wide one. It reported a 250% increase in ATO attacks in 2024, 6.2 million compromised accounts, and 1,027 large organizations targeted by the 22 credential-stuffing groups it infiltrated; 85% of compromised companies already had some form of bot detection. That does not mean all organizations face the same rate, but it does show that “defended” login flows are still monetizable.

Public-sector loss data should be used carefully here. The FBI said IC3 received more than 5,100 ATO-related complaints and more than $262 million in reported losses since January 2025, but those losses include phishing and impersonation-driven account takeover, not only bot-driven credential stuffing. That makes the figure useful for business impact, not for sizing automated login traffic alone.

LexisNexis adds a broader digital-fraud signal: it reported an 8% global attack-rate increase, a 59% rise in bot attacks, login attacks up 89%, and password-reset attack rates reaching 6.6% in its latest cybercrime report. Those are not universal internet statistics, but they reinforce that authentication abuse extends beyond the visible /login page into recovery and reset paths.

Web Scraping, Content Theft, and Competitive Intelligence Bot Statistics

Scraping remains one of the most consistently bot-specific categories in public reports, but the term still needs discipline. OWASP’s automated-threat list includes scraping as OAT-011, while emphasizing that many automation risks are abuse of functionality rather than classic vulnerabilities. Legitimate crawling, licensed data access, partner integrations, and abusive extraction should not be conflated.

Imperva’s 2025 report attributes roughly 31% of API attacks to scraping, and about 37% of API attacks to data-access endpoints. That matters because scraping is now often easier through structured APIs than through rendered pages. In practice, this turns “content abuse” into an AppSec, rate-limiting, authorization, and business-logic problem.

F5’s 2025 bot research shows the same pattern from another angle. It found hospitality web applications absorbed more than 44% bot traffic, driven largely by scraping of hotel room and rate flows. That is a better model for leadership teams than the old “scraping equals page copying” frame. In many sectors, scraping is really market intelligence extraction, pricing exploitation, and inventory discovery at machine speed.

API Bot Abuse and Application Attack Statistics

APIs are no longer a side channel. Akamai’s 2026 preview says the average number of daily API attacks rose 113% year over year and that 61% of API attacks in 2025 involved unauthorized workflows and abnormal activity, up from 30% in 2024. That is a direct signal that the attack problem is moving toward behavior, misuse, and business-flow abuse rather than only textbook payloads.

Imperva’s API-focused analysis is even more useful for buyers mapping controls to endpoints. It found 44% of advanced bot traffic targeted APIs. Within API attacks, data scraping made up about 31%, payment fraud 26%, ATO 12%, and scalping 11%. Endpoint-wise, data-access endpoints saw about 37% of API attacks, checkout 32%, and authentication 16%.

OWASP’s API Security Top 10 explains why these numbers recur. Broken authentication, broken object-level authorization, unrestricted resource consumption, unrestricted access to sensitive business flows, and improper inventory management all map naturally to automated abuse. OWASP explicitly notes that APIs expose sensitive data and application logic and that unrestricted business flows can harm the business when used excessively in an automated manner, even without a conventional implementation bug.

In financial services, the concentration is sharper. Akamai says banking absorbed 60% of total web attacks and 83% of API-endpoint attacks in 2025 in its financial-services threat summary. That is sector-specific telemetry, not a universal count, but it is strong evidence that financial APIs remain one of the highest-value bot and abuse targets.

Ecommerce, Retail, Travel, Ticketing, and Inventory Abuse Bot Statistics

OWASP’s automated-threat model includes denial of inventory, scalping, cashing out, carding, and account creation because modern commerce abuse is often workflow abuse first and code exploitation second. That framing fits the ecommerce data much better than generic “fraud statistics.”

Imperva found the travel industry became the most attacked sector in 2024, accounting for 27% of all bot attacks, up from 21% in 2023, with a 280% rise in bot attacks targeting the travel industry from January 2022 to December 2024. Retail was the second most attacked industry in the same report. It also notes that travel and retail both face high bad-bot shares and that these attacks often connect directly to loyalty fraud, scraping, seat spinning, and ticket and fare manipulation.

Kasada’s campaign-level telemetry reinforces the commerce angle. In the credential-stuffing campaigns it tracked, 20% of the NRF Top 100 retailers were compromised, while 40% of the top 10 U.S. hotel brands suffered account takeover attacks. Its report ties the monetization directly to stored payment details, gift cards, loyalty points, promotions, and seasonal booking spikes.

Sift’s industry benchmarks show why travel and ticketing keep appearing in these reports. It reported an average 2025 ATO rate of 0.82% for travel and ticketing and the highest average payment-fraud attack rate of any listed sector at 4.85%, ahead of food and delivery, internet and software, finance and fintech, and digital commerce. Those are network-level platform rates, not bot-only numbers, but they explain why these journeys are repeatedly abused.

Ad Fraud, Click Fraud, Spam, Fake Account, and Registration Bot Statistics

This is the section where scope discipline matters most. Public ad-fraud reporting often uses “invalid traffic” rather than “bots,” and invalid traffic can include non-human traffic plus other forms of non-legitimate advertising measurement. Pixalate’s Q2 2025 benchmarks found global IVT of 19% on desktop and mobile web, 29% on mobile app traffic, and 18% on CTV across more than 120 billion programmatic impressions. Pixalate also explicitly warns that IVT and “fraud” are measurement terms, not legal findings, and that IVT is not a synonym for pure malicious-bot traffic.

For registration abuse, the cleaner signal comes from account-creation research. Arkose Labs said fake account creation remained the number one attack type in its Q4 2025 threat-intelligence release, accounting for 46% of all fraudulent activity across the nine industries it analyzed. That is vendor telemetry and should be treated that way, but it lines up with the persistent weakness of sign-up flows in consumer-facing platforms.

OWASP’s automated-threat taxonomy supports the same interpretation. Account creation and spamming both sit inside the automated-threat model because bots are often used to farm accounts, distort referral programs, abuse promos, spam forms, and create downstream fraud inventory for later use.

DDoS, Botnets, Proxy Networks, and Infrastructure Abuse Statistics

DDoS botnets are related to bot attacks, but they are measured differently and should stay analytically separate from web bot-traffic share. Cloudflare says it mitigated 47.1 million DDoS attacks in 2025, a 121% increase year over year, averaging 5,376 attacks per hour. It also disclosed a 31.4 Tbps attack and described the Aisuru-Kimwolf botnet as an estimated 1–4 million infected hosts, primarily Android TVs.

NETSCOUT’s 2H 2025 report independently recorded more than 8 million DDoS attacks across 203 countries and territories. It reported attacks up to 30 Tbps and 4 Gpps, more than 45,000 NTP-related attack alerts, and regional concentration led by EMEA at 3.3 million attacks, followed by APAC at 1.9 million, North America at 1.27 million, and Latin America at 1.01 million. Those are infrastructure telemetry figures, not user-session or page-request shares.

Akamai’s 2026 preview adds application-layer context. It says Layer 7 DDoS attacks surged 104% between 2023 and 2025. In financial services specifically, Akamai reports a 738% increase in Layer 3 and Layer 4 DDoS attack duration since 2024 and a 236% increase in maximum volumetric DDoS threat scale between 2024 and 2025.

Proxy infrastructure remains relevant outside pure DDoS. Imperva found 21% of bot attacks using ISP networks were conducted through residential proxies. That matters because these same proxy networks help attackers rotate IPs, mimic consumer origin patterns, and support credential abuse, scraping, and checkout manipulation.

AI Crawlers, LLM Scrapers, and Emerging Bot Traffic Statistics

The AI traffic story is real, but it does not justify panic or lazy classification. HUMAN says AI-driven traffic grew 187% between January and December 2025, agentic AI traffic grew 7,851% year over year, and more than 95% of this traffic centered on retail and ecommerce, streaming and media, and travel and hospitality. It also found that OpenAI-operated bots represented about 69% of observed AI-driven traffic in its dataset.

DataDome’s 2025 testing study found LLM crawlers made up 10.1% of verified bot traffic in August 2025, up 3.9x from January. It also found that only 2.8% of nearly 17,000 tested sites were fully protected against the bot vectors it examined, suggesting that many organizations have policy opinions about AI crawlers without corresponding enforcement depth.

Cloudflare’s 2025 Year in Review adds nuance. It reported that AI bots were 4.2% of all requests for HTML pages on average in 2025, compared with Googlebot at 4.5%, and that AI user-action crawling increased by more than 21x over the course of the year. That means AI crawlers are meaningful but still coexist with established search crawlers and a much larger body of ordinary web and non-AI automated traffic.

The right interpretation is operational. Organizations need to distinguish between AI crawlers they want to allow, AI crawler traffic they want to meter or govern, and AI-driven abuse that overlaps with scraping, agentic checkout, account actions, or unauthorized automation. Treating every AI bot as malicious is as inaccurate as treating every AI bot as benign.

Industry and Regional Bot Attack Statistics

Industry-specific patterns are clearer than regional bot-share patterns in public reporting. Thales and Imperva repeatedly show travel, retail, financial services, education, and API-heavy digital businesses as high-risk sectors, while F5 highlights hospitality on the web and entertainment on mobile APIs. Sift’s consumer-platform and industry benchmarks separately show elevated ATO and payment-fraud exposure in internet software, digital commerce, and travel and ticketing.

Regional data is stronger for DDoS than for bad-bot traffic share. NETSCOUT recorded the highest second-half 2025 DDoS counts in EMEA, then APAC, North America, and Latin America. Cloudflare’s Q4 2025 report showed significant movement in the most-attacked locations, including Hong Kong and the United Kingdom, but that remains DDoS telemetry rather than a general bot-traffic census.

Leadership Interpretation and FAQs

What These Numbers Mean for Security Leaders

These statistics support five priorities.

First, treat authentication as a workflow, not a page. Login, registration, password reset, account recovery, MFA enrollment, session refresh, and loyalty redemption belong in the same abuse model. F5, LexisNexis, Imperva, and the FBI all show that attackers monetize the full account lifecycle, not only a visible login form.

Second, move API security closer to fraud and abuse operations. Akamai, OWASP, and Imperva all show that unauthorized workflows, sensitive business flows, checkout endpoints, authentication endpoints, and data-access endpoints are where abuse concentrates. That makes rate limits, auth, authorization, and business-logic testing central to both AppSec and fraud reduction.

Third, separate alerting by intent. DDoS, AI crawlers, scraping, ATO, carding, fake accounts, and inventory abuse are not interchangeable. Controls, owners, and escalation paths differ. Board reporting should reflect that reality.

Fourth, validate rather than assume. DataDome’s exposure study and Kasada’s ATO findings both suggest many organizations deploy controls that attackers still route around. For high-risk organizations, that justifies safely scoped validation through penetration testing, API penetration testing, web application penetration testing, abuse-case review, and red-team-style assessment on critical flows.

Fifth, keep testing safe and authorized. Bot, API, and DDoS-related validation must be rate-limited, approved, scoped to avoid production disruption, and designed to test exposure rather than recreate uncontrolled abuse. DeepStrike is relevant here as a validation partner for penetration testing, API penetration testing, web application penetration testing, cloud penetration testing, and red team assessments, but those services complement rather than replace dedicated bot-management or fraud-prevention platforms.

Common Mistakes When Using Bot Attack Statistics

The most common analytical mistake is mixing total bot traffic with malicious bot traffic. Thales and Imperva publish separate good-bot and bad-bot shares for a reason.

The second mistake is treating vendor telemetry as universal internet truth. F5’s protected-environment view, DataDome’s website testing, Cloudflare’s network telemetry, and Pixalate’s advertising IVT all measure different things. Those differences are useful, but only when clearly stated.

The third is collapsing fraud-wide statistics into bot-specific claims. FBI ATO losses, Sift payment-fraud rates, and LexisNexis digital-attack rates describe adjacent business risk, but not every underlying event is bot-driven. Use them to frame impact and workflow exposure, not to claim a universal “bot loss” number.

The fourth is ignoring APIs, mobile app flows, registration, checkout, and recovery paths while focusing only on login pages. Current reports consistently show that bots exploit the full customer journey.

FAQs

What are the most important bot attack statistics?

The most decision-useful numbers are the ones that connect traffic share to attack surface. Today that means bad-bot share, API-directed bot activity, ATO and credential-stuffing pressure, scraping rates, DDoS volume, and AI-crawler growth. The strongest current public signals come from Thales, Imperva, Akamai, Cloudflare, HUMAN, F5, and NETSCOUT.

What percentage of web traffic is bots?

That depends on source and year. Thales says bots made up 53% of internet traffic in 2025, while its prior report put 2024 automated traffic at 51%. Those figures are useful, but they are vendor telemetry, not a universal census of every website. The more important split is between good bots and bad bots.

What is the difference between good bots and bad bots?

Good bots are approved or expected automation such as search crawlers and monitoring tools. Bad bots are automated agents used for abuse such as credential stuffing, scraping, fake account creation, or checkout manipulation. Current leading reports separate these categories explicitly because combining them hides the true risk picture.

Why are bad bots a security risk?

Because they target valid workflows at machine speed. Modern bad bots hit logins, account recovery, pricing APIs, checkout flows, rewards balances, and content endpoints. OWASP frames many of these as abuse of application functionality, not only exploitation of conventional software flaws.

How do bots support credential stuffing and account takeover?

Credential stuffing is inherently automated. Attackers test stolen username-password pairs at scale, then monetize successful logins through stored payment methods, loyalty balances, or data theft. Public ATO loss figures also include phishing and impersonation, so the cleanest bot-specific view usually comes from login and auth telemetry, not law-enforcement complaint totals alone.

Why are APIs exposed to bot attacks?

APIs expose data and workflows directly. OWASP notes that APIs expose sensitive data and application logic, while Akamai and Imperva show abuse concentrating around unauthorized workflows, data-access endpoints, checkout, and authentication. APIs also tend to be easier to automate consistently than custom front-end flows.

Which industries are most affected by bot attacks?

Travel, retail, hospitality, digital commerce, financial services, and API-heavy sectors appear repeatedly in current vendor telemetry. The exact ranking changes by source because the datasets differ, but commerce, loyalty-heavy, and transaction-heavy environments remain overrepresented.

How do bots affect ecommerce fraud and inventory abuse?

They distort availability, checkout fairness, promo economics, and fraud operations. Inventory hoarding, scalping, carding, fake accounts, and post-login payment abuse all show up in OWASP’s taxonomy and in current vendor reports. The result is both direct fraud loss and degraded customer experience for legitimate users.

Are AI crawlers and LLM scrapers the same as malicious bots?

No. Some are legitimate or at least expected forms of automated access, while others behave more like abusive scraping or agentic transaction traffic. The useful question is not “AI or not AI.” It is whether the automation is authorized, identifiable, rate-appropriate, and aligned with the site owner’s policy and business model.

What is the difference between bot attacks and DDoS attacks?

Bot attacks usually refer to automated misuse of an application or workflow, such as credential stuffing or scraping. DDoS attacks focus on exhausting availability or capacity. Some DDoS attacks are botnet-driven, but DDoS counts and bot-traffic-share metrics are different measurement categories and should not be merged.

How should security teams reduce bot attack risk?

Focus on high-value flows: authentication, registration, password reset, account management, data-access APIs, checkout, and loyalty or gift-card actions. Then validate auth, authorization, rate limits, workflow assumptions, monitoring, and incident response. The statistics support layered controls, but they do not replace direct exposure testing.

How often should bot controls and abuse paths be tested?

There is no universal cadence, but annual testing alone is weak for high-risk consumer platforms, ecommerce, and API-heavy services. Critical flows should be reassessed after major releases, auth changes, loyalty or checkout changes, third-party integration changes, and meaningful attack-pattern shifts. Safe, authorized testing matters more than arbitrary frequency.

Conclusion

The most useful bot attack statistics in 2026 show three things. First, bad bot traffic is large enough to affect normal planning assumptions. Second, the highest-risk abuse is concentrated around credential stuffing, account takeover, scraping, API abuse, fake accounts, ecommerce and inventory manipulation, and DDoS botnets rather than around one generic “bot problem.” Third, AI crawlers and agentic automation have added policy and monitoring complexity without removing the need for security fundamentals. Statistics can guide prioritization across login flows, APIs, customer portals, ecommerce checkout, cloud infrastructure, and internet-facing applications, but bot attack statistics do not replace validation. Security, fraud, and product teams still need to test real workflows, assumptions, and controls.
