Bad Bot Arms Race Rages On
April 18, 2019
Networks released its annual Bad Bot Report
titled, “Bad Bot Report 2019: The Bot Arms
Race Continues.” The report investigates
hundreds of billions of bad bot requests
from 2018 over thousands of domains to
provide deeper insight into the daily
automated attacks wreaking havoc on
websites, mobile apps and APIs. The findings
suggest that bot attack sophistication
continues to evolve, as advanced attackers
learn to adapt their techniques in order to
invalidate existing defense tactics.
73.6 percent of bad bots are classified as Advanced Persistent Bots (APBs), which are characterized by their ability to cycle through random IP addresses, enter through anonymous proxies, change their identities, and mimic human behavior.
Nearly 50 percent (49.9 percent) of bad bots report their user agent as Chrome. Mobile browsers, such as Safari Mobile, Android and Opera increased from 10.4 percent last year to 13.9 percent.
Amazon is the leading ISP for originating bad bot traffic. In 2018, 18 percent of bad bot traffic originated from Amazon compared with 10.62 percent the previous year.
Despite the fact that 53.4 percent of bot traffic originates from the United States, Russia and Ukraine combined make up nearly half (48.2 percent) of country-specific IP block requests.
This year’s report provides a comprehensive breakdown of some of the top industries impacted by bots and the specific challenges they face. Key findings include:
