Stop Account Takeover

Q: How to detect account takeover attempts?

Account takeover detection analyzes multiple risk signals: 1. Device Intelligence — flags logins from new or suspicious devices, 2. Behavioral Analysis — detects impossible travel and unusual login patterns, 3. Bot Detection — identifies automated credential stuffing tools, 4. Risk Scoring — combines signals into a single risk score. BotBye uses all four methods with a dedicated ATO Score (0-100) that evaluates every login in real time.

Protection Across the ATO Attack Surface

Account takeover (ATO) occurs when attackers gain unauthorized access to legitimate user accounts. They may use stolen credentials, session hijacking, automated attacks, and other techniques to bypass authentication and take control of an account. BotBye provides complete protection against all account takeover attacks, including credential-based attacks, session hijacking, and automated login abuse.

Attackers exploit stolen, leaked, or reused credentials from data breaches. Includes credential stuffing (testing stolen password databases against login endpoints), password spraying, and attacks using leaked credentials from third-party breaches.

Attackers steal active session tokens through session hijacking, cookie theft, or man-in-the-middle attacks. Once stolen, tokens are replayed to access accounts without knowing the password.

Bot-driven login abuse including brute force attacks, automated account enumeration to identify valid usernames, and high-velocity login attempts.

Complete Account Takeover Protection

From phishing detection to real-time login blocking, BotBye stops account takeover attacks even when credentials are already stolen.

FAQ

What is account takeover (ATO)?

Account takeover (ATO) is when attackers break into user accounts without authorization. They get credentials through credential stuffing (testing stolen passwords), phishing (fake login pages), session hijacking (stealing session tokens), or brute force attacks (trying password combinations). Once in, they steal data, make fraudulent purchases, transfer funds, or access sensitive information. This is particularly damaging for e-commerce, banking, iGaming, and SaaS platforms.

How to detect account takeover attempts?

Account takeover detection analyzes multiple risk signals:1. Device Intelligence — flags logins from new or suspicious devices,2. Behavioral Analysis — detects impossible travel and unusual login patterns,3. Bot Detection — identifies automated credential stuffing tools,4. Risk Scoring — combines signals into a single risk score.BotBye uses all four methods with a dedicated ATO Score (0-100) that evaluates every login in real time.

Can BotBye detect account takeover if the attacker has valid credentials?

Yes. Even with valid credentials, BotBye detects takeovers through behavioral signals: device fingerprint, geolocation data, and velocity patterns. If the ATO Score indicates high risk, BotBye triggers a CHALLENGE (step-up MFA) or BLOCK, preventing account compromise.

Will BotBye block legitimate users?

BotBye minimizes false positives with risk-based decisioning: ALLOW (low-risk logins pass with zero friction), CHALLENGE (medium-risk triggers MFA when needed), BLOCK (high-risk denied). You control the ATO Score thresholds and adjust based on your risk tolerance.
