According to a Juniper Research report, the world is facing an unprecedented surge in ATO fraud. This threatens the security of entire accounts, alongside associated payment data. Global ATO fraud is expected to cost in excess of $206 billion over the next five years.

For any finance or accounting executive seeking to strengthen their organisation’s resilience against fraud, ensuring your systems are not susceptible to account take overs must be an urgent priority.

What is ATO fraud?

Put simply, ATO fraud involves credential theft, perpetrated by cyber-attackers, with the goal being to defraud a victim organisation.

Typically, ATO fraud starts with compromising credentials. Cyber-attackers will seek to obtain usernames and passwords to applications, such as email accounts or online bank accounts, that will give them the ability to steal the organisation’s financial assets.

How is ATO fraud perpetrated?

Some of the common methods cyber-attackers use to perpetrate ATO fraud include:

·         Malware

Attackers engaging in ATO fraud may infect your organisation’s computer systems with malicious software, or malware, that is designed to steal user credentials. Common types of malware used in these types of attacks include spyware and keyloggers.

Spyware is a type of malware that is designed to gather intelligence on an organisation and access its confidential data. Spyware is specifically designed to steal confidential data, including login and password credentials to networks, files and applications, including email accounts and online bank accounts.

Keyloggers are a type of malware that records every keystroke typed on a keyboard. It can also allow cyber-attackers to obtain confidential authentication details, such as logins and passwords, once again giving the criminals access to the organisation’s online bank accounts and email accounts.

·         Phishing

Phishing uses electronic communications channels to deceive staff into taking an action that they otherwise would not take.

When it comes to ATO fraud, we see many cases where phishing emails are sent out by cyber-attackers which include malicious links. These direct unsuspecting staff to a fake online banking webpage that looks identical to the real online banking webpage. The staff member innocently enters their online banking username and password.

At this point, the attackers have managed to gain the login credentials to the target organisation’s online bank accounts, paving the way for ATO fraud.

·         Social Engineering

Social Engineering is the attempt by cyber-attackers to deceive staff into revealing confidential information, such as usernames and passwords to corporate systems. A variety of methods may be used to conduct Social Engineering, including email, telephone and social media communications.

Social Engineering works because it takes advantage of the innate human desire to be helpful. A sophisticated cyber-attacker will have already conducted extensive background reconnaissance and will be highly experienced in the art of deception. For example, they may impersonate representatives of your bank as a way to deceive staff into revealing online banking credentials.

·         Credential Stuffing

All too often people reuse the same password across multiple applications. This increases the risk that if a cyber-attacker manages to obtain login credentials to one system, they will attempt to gain unauthorised access to other systems using the same credentials.

This is a particular problem given the volume of usernames and passwords that can be acquired through the Dark Web.

Using automated scripts, cyber-attackers attempt to gain access to thousands of web applications using stolen credentials. Sometimes this results in them successfully accessing email accounts or online bank accounts, paving the way for ATO fraud.

·         Brute Force Attacks

Using automated scripts, cyber-attackers may seek to bombard a web application with thousands of potential passwords. Often they will attempt commonly used passwords, or passwords that have some relevance to the user they are seeking to compromise.

When users do not select sufficiently complex passwords, it makes the chance of a brute force attack succeeding more likely.

Once an attacker gains access to an application through a brute force attack, they will be able to engage in ATO fraud.

·         Man-In-The-Middle Attacks

With decentralised staff, the risk of a man-in-the-middle attack has risen significantly.

Man-in-the-middle attacks involve cyber-criminals setting up fake Wi-Fi networks in public locations. Staff may think they are connecting to a secure public Wi-Fi network, for example in a coffee shop, when in actual fact they are allowing an attacker to eavesdrop on all their communications and access data being transferred over the internet.

This opens the door to the attacker to access confidential login credentials to systems such as email or online bank accounts. Armed with a username and password, the organisation will find itself exposed to a fraud event.

What are the different types ATO fraud?

Once the cyber-attacker gains unauthorised access to your online bank account, they will often sit in wait until the ideal opportunity arises for them to launch a fraud event. During this time they will likely mimic normal user behaviour, in order not to raise any suspicions.

When the cyber-attacker determines that the time is right, they will most likely engage in one of the following attack vectors:

·         Business Email Compromise (BEC)

With access to an executive’s email account, an attacker may impersonate the executive to issue instructions to staff to process payments to a bank account controlled by the attacker.

·         Vendor Email Compromise (VEC)

With access to an organisation’s Accounts Receivable (AR) email account, an attacker may issue fake invoices to the organisation’s customers, with any payments directed to a bank account controlled by the attacker.

·         Direct Financial Theft

In the event that a cyber-attacker gains access to an organisation’s bank account, they will likely choose an opportune time, such as during the weekend or a public holiday, to transfer funds out of the account and into a bank account they control. Selecting the right time can ensure that alarms are not raised until it’s too late.

·         Business Identity Theft

Cyber-attackers may steal other sensitive corporate data that enables them to engage in a range of other crimes by impersonating the company’s executives. Known as Business Identity Theft, this can pave the way for the attacker to obtain loans or credit in the organisation’s name.
