Account takeover fraud can cause serious problems, making it difficult for customers to reclaim their accounts without suffering a financial loss. To make matters worse, the relationship between the customer and the business could be irrevocably damaged.
In 2025, account takeover (ATO) fraud has surged into one of the most dangerous and rapidly evolving threats facing digital businesses. As fraudsters weaponize data breaches, generative AI, and social engineering, user accounts across financial services, eCommerce, social media, and gaming platforms are at unprecedented risk.
Account takeover (ATO), where cybercriminals gain control of online accounts using stolen credentials, and multi-accounting, the creation of multiple accounts to exploit promotions or bonuses, saw significant growth in 2024. According to Veriff Identity Fraud Report 2025, ATO incidents rose by 13% compared to 2023, while multi-accounting cases increased by 10% year-over-year.
Account takeover fraud (ATO) is when fraudsters gain access to a customer’s account without their permission, a type of identity theft. Any online account can be targeted, with the potential for huge financial damage.
In committing ATO fraud, a criminal actor will go through two steps. First, the fraudster gains access to the victim’s account by deploying stolen account information or information they’ve bought.
Once a fraudster has gained access, they will make non-monetary changes to the account. These include:
The fraudsters can then make a series of unauthorized transactions that appear legitimate. Alternatively, they may sell the confirmed account or the customer’s data to someone else.
Utilizing these illicitly obtained credentials on a large scale constitutes credential stuffing. Credential stuffing is one of the most common techniques for taking over user accounts. Credential stuffing is dangerous to consumers and enterprises because of the ripple effects of these breaches. One of the other challenges is the common practice of users utilizing identical passwords and usernames/emails across multiple platforms. If these credentials are compromised through means such as a database breach or phishing scheme, inputting these stolen credentials into numerous other websites can potentially grant an attacker access to those accounts as well.
The Veriff Fraud Report 2025 reveals critical insights into how the ATO threat is evolving:
Hackers use leaked credentials from past data breaches to fuel bots that test login combinations across countless platforms. This process is fast, automated, and highly effective, especially when users reuse passwords.
Many organizations still rely on SMS-based multi-factor authentication (MFA), which can be easily bypassed through SIM swapping. Without robust identity verification, these vulnerabilities are prime targets for attackers.
Cybercriminals have turned to generative AI to enhance their tactics, creating realistic deepfakes, mimicking legitimate user behavior, and spoofing biometric data. Traditional detection methods are quickly becoming ineffective against these advanced techniques.
Recent reports show a staggering 2,100% rise in fraud attempts involving deepfakes over just three years. Criminals are no longer limited to phishing or stolen credentials—they’re now leveraging AI-generated audio and video impersonations to outsmart even the most advanced verification systems.
Spoof biometric systems like facial and voice recognition
While the financial industry bears the brunt, this growing threat impacts all sectors. Combating synthetic identity fraud demands multi-layered defenses, including AI-enhanced liveness detection, real-time behavioral monitoring, and cross-industry fraud intelligence sharing.
Outdated fraud detection systems and fragmented verification processes leave gaps that fraudsters exploit, particularly in industries rapidly adapting to digital transformation.
Cybercriminals in 2025 employ increasingly advanced techniques to execute account takeover (ATO) fraud at scale. Phishing and spear phishing campaigns impersonate trusted brands or individuals to trick users into revealing their login credentials, while AI-enhanced credential stuffing uses machine learning to automate and optimize password-guessing attempts across multiple platforms. Meanwhile, malware and device hijacking tactics like keyloggers and remote access trojans silently collect sensitive data or hijack user sessions.
According to Veriff Ifentity Fraud Report 2025, one of the most dangerous evolutions in this space is emulator-based ATO, where fraudsters use sophisticated software to mimic real devices, bypassing traditional security measures like device fingerprinting and behavioral analytics. These emulators allow attackers to simulate trusted environments, making unauthorized access appear legitimate, and enabling high-volume, stealthy takeovers that can lead to severe financial and reputational damage.
A parallel and increasingly prevalent threat is Business Email Compromise (BEC) — a rapidly expanding ATO subtype. As highlighted in recent findings, BEC schemes exploit compromised or spoofed business email accounts to manipulate employees, particularly within finance teams, into authorizing fraudulent transactions. Common tactics include domain spoofing, social engineering, and fake invoices or wire transfer requests. These attacks are surging in frequency and sophistication, with BEC losses estimated to have reached billions globally in 2025. The scale of this threat underscores the urgency of implementing strong ATO prevention strategies, including robust email authentication, vigilant employee training, and multi-factor authentication.
Account Takeover (ATO) fraud continues to be a significant and escalating threat, resulting in substantial financial losses worldwide. Recent data underscores the severity of this issue:
These figures highlight the critical need for robust cybersecurity measures and proactive strategies to mitigate the growing risk of ATO fraud.
