ATO
Abbreviation for Account takeover
In short and in plain language
ATO is when attackers take over a customer's account.
They usually do this with stolen login details. After that, the account looks like a normal customer.
That is why the takeover is hard to notice. Watching the logins can help to spot such cases.
Definition
ATO describes attackers gaining control of an existing customer account, usually with stolen credentials. The account then looks like a normal customer, which is why the takeover is hard to notice. Monitoring of logins can help to detect such cases.
