tl;dr:
- Cybercriminals are bypassing IT defences by targeting the human element in finance through whaling and CEO fraud.
- CFOs must increasingly shift towards being strategic risk leaders by recognising cyber threats as material financial risks.
- Implementing the Four-Eye Principle and dual-approval workflows is now a non-negotiable safeguard.
- Deepfake technology is the new frontier for cyber risk in 2026. Organisations should establish more multi-channel verification protocols like voice and video verification to mitigate sophisticated spoofing techniques.
- Training finance teams to challenge urgency and verify instructions is your strongest line of defence.
For years, cybersecurity was viewed as a technical skirmish fought in the server rooms by the IT department. If the firewall was up and the antivirus was green, you would assume the fortress was secure. But the landscape has shifted dramatically. Today, the most sophisticated cyber attack does not target a software vulnerability. Instead, it targets the person with the keys to the treasury: you.
As a finance professional, you sit at the intersection of liquidity and authority. This makes you, your department, and your organisation the primary target for modern cybercriminals. These threats are not just random spam, but rather precision-engineered whaling attacks and CEO fraud designed to bypass every technical layer of your security stack by exploiting human trust.
In this article, we explore why CFOs and finance teams are critical to safeguarding corporate trust, how to establish a robust human firewall, and why cybersecurity should become a cornerstone of your 2026 strategy.
why are CFOs and finance teams the primary targets for cybercriminals?
Let’s approach this practically: why would a hacker spend months trying to crack a 256-bit encryption when they can simply convince a controller to click "approve" on a fraudulent FAST or PayNow for Business transfer?
Cybercriminals follow the money. In any organisation, all roads lead to the finance department. You control the wires, the payroll, the M&A funds, and the banking tokens. Furthermore, your role is inherently public. Between LinkedIn profiles, earnings calls, and SGX filings, hackers have a blueprint of your hierarchy and current projects.
The rise of the whaling attack (a form of phishing specifically aimed at the "big fish" like CFOs and CEOs) is no accident. In Singapore, the threat is escalating. The Cyber Security Agency of Singapore (CSA) has consistently highlighted that business email compromise and AI-enhanced phishing account for a major portion of malicious activities. According to MAS reports, financial institutions must remain vigilant as threat actors increasingly target high-value transactions.
When a hacker impersonates a CEO during a high-pressure acquisition, they are not fighting your IT. They are fighting your psychology.
understanding the psychology behind CEO fraud.
CEO fraud, often categorised as Business Email Compromise (BEC), is a masterclass in psychological manipulation. It usually begins with a spoofed email that looks identical to your Chief Executive’s address. The message is simple: "I am in a confidential meeting. We need to secure this vendor today. Keep this quiet until the official announcement."
By combining authority with urgency and secrecy, attackers create a "perfect storm" that pressures finance professionals to bypass standard logical review. This pressurises even seasoned professionals, playing on the fear that they might hinder a critical deal. It leads them to override internal controls to satisfy an executive request.
In Singapore’s business culture, where hierarchical respect and efficiency are highly valued, this pressure comes off even stronger. When senior management issues a request, the instinct is often to follow the directive quickly, rather than to question it.
the “four-eye” principle: why dual approval is your best strategic safeguard.
If the threat is human, the solution must be procedural. This is where the “four-eye” principle moves from being a compliance box-tick to a strategic shield.
The “four-eye” principle is a simple but powerful control, where no single individual should have the authority to both initiate and approve a financial transaction. By requiring at least two people to review and authorise critical payments, organisations can minimise malicious activity.
This approach is aligned with the MAS Technology Risk Management (TRM) Guidelines, which emphasise strong access controls. But in 2026, organisations need to go further. Dual approval should not be limited to just your ERP system – but also be embedded within your communications.
tactical safeguards to implement today:
- Mandatory call-backs: Any change to vendor bank details or urgent out-of-cycle payment requests must be verified via a known phone number. Never use the contact details provided in the suspicious email.
- Threshold-based escalation: For payments above a specified amount (e.g. S$50,000), a three-way sign-off involving the CFO, a director, and treasury should be involved.
- ERP-bank sync: Ensure your bank-side release controls reflect your internal hierarchy. If a payment is not dual-signed at the bank, your internal process is moot.
how the threat landscape has shifted in 2026: deepfakes in finance.
The game changed when AI entered the fray. "Hybrid attacks" are now the norm, where an email from the CEO is followed by a voice-cloned phone call or even a deepfake video in a Microsoft Teams meeting.
Imagine receiving a call that sounds exactly like your CEO, discussing a project you know is active, and asking for a payment to be moved. The human element (our reliance on sight and sound) is being weaponised. To counter this, cybersecurity in financial services now requires a "safe word" protocol.
In high-stakes environments, pre-agreed, non-digital verification phrases or out-of-band multi-channel confirmations are becoming the new standard. For instance, you might confirm a voice request via a separate encrypted chat app or a physical token.
empowering your finance teams as human firewalls.
No matter how robust your verification systems are, it is human judgement that provides the strongest line of defence against cyber attacks. Your team is not the "weak link", but rather, your most intelligent sensors. When empowered with the right knowledge and resources, they can form the organisation’s most effective firewall – but it has to start from shifting towards a culture of curiousity.
- Cyber drills for finance: Simulating realistic, targeted whaling attacks can encourage employees to think critically and respond appropriately, rather than them just going through a generic phishing test.
- Zero-blame reporting: Encouraging your employees to report suspicious activity without fear reinforces a mindset of inquiry, allowing them to actively investigate potential threats instead of ignoring them.
- Governance as resilience: By linking these controls to fiduciary duty and SGX sustainability obligations, you make it easier for management to buy-in and invest in necessary initiatives.
Cybersecurity is no longer “just an IT footnote”, but a fundamental pillar of modern financial stewardship. In 2026, the strongest defence against cyberattacks is not a better algorithm – but a finance team that has the confidence to pause, verify, and challenge the sense of urgency.
By leading this shift, you do more than just protecting the balance sheet – you are safeguarding the very reputation of your organisation.

-
which attack occurs when a hacker targets high-profile individuals like CEOs and executives?
This is known as a whaling attack. It is a specialised form of phishing that uses deep research to impersonate trusted colleagues and trick leaders into compromising data or funds.
-
what is the primary goal of a CEO fraud attack?
The goal is to exploit the authority of a high-ranking executive to bypass standard financial controls. This typically results in an unauthorised wire transfer (such as via MEPS or FAST) or the theft of sensitive financial data.
-
how can finance teams prevent CEO fraud?
The most effective methods include implementing the “four-eye” principle (dual approvals), mandatory verbal verification for payment changes, and regular training on social engineering tactics tailored to the Singaporean regulatory landscape.
-
what is a "human firewall" in finance?
It refers to a team of professionals who are trained to recognise, question, and report suspicious activity. They serve as a critical layer of defence that technical software cannot provide.
