Scenarios

Potential Security Challenges

Account Theft

Account theft can cause data leaks and fraudulent transactions, which harms your interests. CAPTCHA provides multiple types of interactive Turing tests and uses a risk analysis engine to detect suspicious logon attempts that involve credential stuffing attacks, frequent behaviors or operations, and bot scripts. This prevents fraudulent logons from the black market and protects account security in an efficient manner.

False Account

False accounts are a major Internet issue that is faced by all account system-based platforms. This issue can lead to more resource abuses, fraudulent transactions, false polls, and malicious and junk information in forums. CAPTCHA identifies suspicious behaviors in account registration and logon based on automated scripts and device risk characteristics. You can verify the identification results to prevent malicious account registration without affecting the experience of real users.

SMS Flood Attack

SMS flood attacks can cause the unavailability of text message channels and lead to great economic losses for platforms. In addition, platforms may receive a large number of complaints from users due to harassment. CAPTCHA uses behavioral CAPTCHA to identify bot traffic before text messages are sent and blocks most automated attacks based on multiple dimensions such as the request frequency for sending text messages, traffic characteristics, and device risk level. This greatly reduces the cost of the SMS service.

Marketing Activity Cheating

During marketing activities, malicious groups obtain coupons and discounts by using illegal methods. To obtain marketing resources, malicious groups register plenty of accounts and participate in marketing activities by using these accounts. This wastes a large amount of marketing resources. You can deploy CAPTCHA in multiple stages such as account registration, logon, and key steps before business operations. CAPTCHA identifies and blocks automated behaviors based on behavior characteristics. This greatly increases the cost of cheating and protects your marketing resources.

Scarce Resource Occupation

Malicious groups register bulk accounts and use automated scripts to generate fraud traffic and occupy scarce resources such as flight tickets, ticketing services, online appointment in hospitals, high-value commodities, game accounts, and information about transactions or enterprises. CAPTCHA provides security services in multiple interactive stages such as account registration, logon, password retrieval, search, message delivery, order placement, and coupon obtainment. This helps you establish a comprehensive risk control system for your business, protects sparse resources, and ensures the benefits of customers.
