How Account Takeovers Happen
Learn how criminals gain control of existing accounts through stolen credentials or deceptive requests, and how to secure access and recover after suspicious activity.
An existing account becomes the target
Account takeover means someone gains unauthorized control of an account that already belongs to you. It can affect email, banking, shopping, social media, or cloud storage. Criminals may use stolen passwords, deceptive sign-in pages, or abused recovery processes. They may also steal an active session, so a password is not always the only factor.
Email access can expand the damage
Your email often receives password resets and security notices for other services. Someone with access may change recovery details or hide messages using forwarding rules and filters. Secure your main email account carefully. Review its settings after suspicious activity, even if you can still sign in and no unfamiliar message appears in the inbox.
Use independent checks before approving requests
A sign-in prompt or support message may arrive while a criminal is trying to access your account. Do not approve unexpected requests or share verification codes. Open the service through your usual app or a trusted address. Unique passwords and strong multifactor authentication can reduce risk, especially when you avoid reusing credentials across services.
Recovery requires more than a new password
Use the provider's official recovery process if you lose access. After regaining control, change the password, review recovery methods, and end unfamiliar sessions. Remove unauthorized forwarding rules or connected apps. Check recent transactions and messages. Warn contacts if the account sent scams, and preserve evidence before removing content that could help an investigation.
