ATO Prevention

Account Takeover Protection

Stop credential stuffing, brute force, and session hijacking before accounts are compromised — with zero friction for legitimate users.

Account takeover protection blocking credential stuffing and brute force login attacks in real time

How account takeover attacks happen — and how DataSec stops them

Step 1: Breach data acquisition

Attacker

Bot operator purchases a credential dump from a dark web marketplace (billions of real username:password pairs).

DataSec response

DataSec monitors known breach publication sources and updates detection models to recognize stuffing patterns before attacks reach your login page.

Step 2: Credential stuffing at scale

Attacker

Automated tools (SentryMBA, SNIPR, OpenBullet) test credentials across thousands of IPs using residential proxy networks to avoid IP-based blocks.

DataSec response

TLS fingerprinting identifies automation frameworks regardless of IP. Behavioral signals detect non-human interaction with login forms. Rate limiting applies per-device-fingerprint, not just per-IP.

Step 3: Account access & monetization

Attacker

Compromised accounts are used to steal payment methods, drain loyalty points, make fraudulent purchases, or resell access.

DataSec response

Post-login session monitoring detects anomalous behavior. Suspicious sessions are challenged without disrupting real user sessions on the same account.

FAQ

Frequently asked questions

Credential stuffing uses real credentials from breached databases — it exploits password reuse across services. Brute force guesses passwords systematically. DataSec detects both: credential stuffing by request pattern and known-breach signal correlation, brute force by rate-pattern analysis per target account.
