What is Account Takeover?

Account takeover (ATO) is an attack where an unauthorized individual gains control over a victim's online account. It typically occurs when a malicious third party successfully acquires the victim's login credentials, such as usernames and passwords, through various means such as phishing, social engineering, data breaches, or malware.

During an account takeover, the attacker gains unauthorized access to the victim's account and assumes control over it. This can result in severe consequences, including financial loss, data breaches, privacy violations, reputational damage, and even potential harm to the victim's personal or professional life.

Account takeover is closely related to identity theft, but it’s important to note the distinction between the two:

  • Identity theft: Identity theft involves stealing someone's personal information, such as their name, social security number, or financial details, with the intent to impersonate them or commit fraudulent activities in their name. It encompasses a broader range of fraudulent actions beyond just taking control of online accounts. A variation of identity theft is synthetic identity theft (SIF), where the criminal steals real information from several different sources to create a fake identity that is then used to commit fraud.
  • Account takeover: Account takeover specifically refers to the unauthorized access and control of an individual’s online accounts, where the attacker gains the ability to manipulate or exploit the account, often using social engineering tactics to gain the victim’s trust. While it is a form of identity theft, the focus is primarily on compromising and using the victim's online accounts rather than stealing their overall identity.

Account takeover is a growing security threat. When attackers gain unauthorized access to victims' online accounts, they compromise customer control and can potentially harm the individual and financial institution (FI). It’s important for customers and FIs to employ strong security practices, such as:

  • Using unique and complex passwords
  • Enabling two-factor authentication
  • Monitoring account activities regularly
  • Staying vigilant against phishing attempts

These actions help to mitigate the risk of account takeover.

How can NICE Actimize Help?

NICE Actimize provides financial crime prevention and compliance solutions that mitigate the risks associated with account takeover. Here are some ways in which NICE Actimize can assist in combating account takeover:

  • Fraud Detection and Prevention: NICE Actimize provides fraud detection and prevention capabilities specifically tailored to combat account takeover. These solutions use machine learning and artificial intelligence algorithms to analyze multiple data points, including login attempts, transaction patterns, and account access details, to identify potential account takeover incidents in real time. This enables FIs to quickly respond and take appropriate action to prevent unauthorized access.
  • Multi-Factor Authentication (MFA): NICE Actimize offers solutions that support the implementation of robust multi-factor authentication (MFA) methods. MFA adds an extra layer of security to account logins by requiring users to provide additional verification factors, such as one-time passwords, biometric data, or hardware tokens. By implementing MFA, the risk of ATO can be significantly reduced.
  • Risk Scoring and Decisioning: NICE Actimize provides risk scoring and decisioning capabilities that assess the likelihood of an account takeover incident. By leveraging various risk factors and historical data, their solutions can assign risk scores to user accounts and transactions, enabling financial institutions to prioritize and allocate resources effectively to address potential threats.
  • Case Management and Investigation: In the event of an account takeover, NICE Actimize offers case management and investigation tools that enable FIs to efficiently handle incidents. These tools provide a centralized platform for tracking and managing cases, facilitating collaboration among investigators, and ensuring timely resolution of account takeover incidents.

By leveraging NICE Actimize's solutions, financial institutions can enhance their security posture and proactively detect and prevent account takeover attempts. These technologies help to identify suspicious activities, implement stronger authentication measures, assess risks, and streamline the investigation process, mitigating the impact of account takeover on both the FI and its customers.
