A fifth of all web traffic (20.4 percent) comes from bad bots, which continue to attack daily in automated offensives on websites, mobile apps and APIs. The financial services industry sees nearly half of all website traffic coming from malicious bots. 73.6 percent of bad bots can now be classified as advanced persistent bots (APBs) APBs carry out significant assaults using fewer requests and can even delay requests, all the while staying below request rate limits. Increasing volume of stolen credentials from data breaches is also creating a worsening bot problem.
