Invisible Challenges

How HUMAN detects and blocks bots and attackers without the end user seeing the challenge

Invisible challenges are a key component of HUMAN's Bot Defender, designed to detect and mitigate bot and attacker activities with minimal impact on legitimate users. These challenges operate behind the scenes, making it difficult for attackers to reverse engineer or bypass them

These challenges usually contain the following characteristics:

• Harder to reverse engineer: Invisible challenges are designed to be complex and difficult for attackers to understand and maneuver around them.
• Detect advanced attacks: Capable of identifying sophisticated attack patterns and behaviors.
• Detect spoofing: Invisible challenges can identify attempts by advanced bots (for example, gen3 bots) to disguise themselves as simpler bots.
• Increase attack cost: By forcing attackers to expend more CPU and GPU processing time and resources, invisible challenges reduce the return on investment (ROI) for attacks, thereby deterring them.

Invisible challenges work by doing the following:

• Detection and Delay: Invisible challenges do not block traffic directly. Instead, they introduce delays and increase the complexity of the attack, making it less effective. This process is transparent to legitimate users, ensuring minimal disruption.
• Integration with Human Challenge: Invisible challenges are implemented within the Human Challenge framework. They only impact users who have already been served a Human Challenge, further hardening the detection process against malicious operators.
