Bank Fraud: A 24-hour delay could save millions of euros from fraudsters –
Why are Greek banks ignoring the solution they implement abroad?
Import
In the era of the digital revolution, banking fraud has become one of the most serious problems faced by Greek consumers. With 399,000 fraudulent transactions in 2024 and financial losses exceeding 20 million euros annually, the need for effective solutions becomes imperative. However, there is a simple and proven effective solution that is successfully implemented in other countries, but Greek banks seem to blatantly ignore it.
Manolis Sfakianakis, a cybersecurity and forensics expert, recently highlighted in post an innovative solution that could solve the problem of bank fraud almost overnight. His proposal is as simple as it is effective: implementing a 24-hour delay for first transactions to new recipients, as is already successfully implemented in Dubai and other advanced banking markets.
The question that arises is simple but crucial: Why do the directors of Greek banks – from National Bank and Alpha Bank to Eurobank and Piraeus Bank – refuse to adopt a solution that would protect millions of Greeks from the devastating consequences of cyber fraud?
The Dark Reality of Banking Fraud in Greece
Shocking Numbers
The Bank of Greece’s 2024 figures reveal a worrying reality that Greek banks are trying to hide behind technical terms and percentages. Despite the apparent 11% decrease in the total number of frauds compared to 2023, certain types of cybercrime are showing an explosive increase that should be causing sleepless nights for bank boards.
Specifically, CNP (Card-Not-Present) transactions – that is, online transactions without the physical presence of a card – increased by 4% in number, reaching 349,000 cases, while the financial loss amounted to 17.7 million euros. Even more worrying is the 22% increase in the value of ATM fraud, which reached 2.4 million euros.
What makes the figures even more stark is the distribution of costs: 58% of the financial loss is borne by consumers themselves – the victims of fraud. Banks, which should be protecting their customers, bear only 8% of the costs, while the remaining 35% is borne by payment service providers.
The Human Dimension of Tragedy
Behind every statistic lies a human tragedy. Families losing their life savings in a few minutes, seniors seeing their pensions disappear with a click, businessmen devastated by BEC (Business Email Compromise) attacks. The Greek Police recorded only in May 2025 the dismantling of two criminal organizations that had taken 630,000 euros from countless victims.
Most tragic of all is that most of these frauds could be prevented by implementing a simple technological solution that costs banks little but would protect millions of citizens.
The Revolutionary Solution That Greek Banks Are Ignoring
The Sfakianakis Proposal: Simplicity That Saves Lives
Manolis Sfakianakis, with his experience in the field of cybersecurity and forensics, has put a spotlight on a solution that could radically change the landscape of banking fraud in Greece. His proposal is strikingly simple: when a transaction is made for the first time from an account to a new recipient, a 24-hour delay should be automatically applied.
During this delay, the account holder will be immediately notified via SMS and email of the pending transaction, giving them the opportunity to cancel it if they have not authorized it. This mechanism would constitute an impenetrable firewall against the most common forms of cyber fraud.
This solution would be particularly effective in cases where fraudsters steal passwords and hack into bank accounts to make transfers. It would also offer critical protection against BEC (Business Email Compromise) attacks, where criminals forge business emails to trick companies into transferring money to accounts they control.
The Dubai Model: Proven Success
Sfakianakis’ proposal is not theoretical – it is based on proven successful models already implemented in advanced banking markets. Dubai, as one of the leading global financial centers, has adopted this mechanism with impressive results.
Dubai banks , including Emirates NBD, ADCB (Abu Dhabi Commercial Bank), and FAB (First Abu Dhabi Bank), are implementing mandatory delays for first-time transactions to new recipients. The result? A dramatic reduction in successful cyber fraud and a significant boost to consumer confidence in the banking system.

International Success Stories
The model is not limited to the Arab world. Singapore, through its leading banks such as DBS Bank and OCBC Bank, has implemented similar measures with excellent results. In Canada, Royal Bank of Canada (RBC) and Toronto-Dominion Bank (TD) have adopted advanced delay systems that have reduced fraud by more than 60%.
Even in Australia, Commonwealth Bank, ANZ, and Westpac have introduced confirmation and delay mechanisms that protect their customers from cybercriminals. The common feature of all these successful applications is the simplicity of the solution and the dramatic improvement in security without significantly burdening the user experience.
Greek Banking Inaction: Who Is to Blame?
The Culture of Indifference
The problem is not limited to the big banks. Other smaller banks are also following the same pattern of inaction. It seems that there is a systemic culture of indifference to customer safety that permeates the entire Greek banking sector.
This stance becomes even more provocative when we consider that Greek banks have invested billions of euros in digital transformation in recent years. They have the money for impressive advertising campaigns and luxurious buildings, but they seem to lack the will to invest in a simple solution that would protect their customers.
The Cost of Inactivity
The inaction of Greek banks is not just an administrative failure – it is a moral condemnation. Every day that passes without the implementation of this solution, hundreds of Greek citizens become victims of fraud that could have been avoided. Every week that bank managers choose inaction, thousands of euros disappear from the accounts of innocent citizens.
Most outrageous of all is that this solution does not require huge investments or complex technological changes. It is a relatively simple modification of existing systems that could be implemented in a few months. The only requirement is the willingness of bank management to put customer security above their own convenience.
How the Solution Works: Technical Details
The Protection Mechanism
The implementation of the solution proposed by Sfakianakis is impressively simple from a technical point of view. When a customer tries to make a money transfer to a recipient with whom they have not transacted in the past, the bank's system will:
1. Recognizes that this is the first transaction to this recipient
2.Puts the transaction on hold for 24 hours
3.Sends SMS and email immediately to the account holder with the transaction details
4. Provides easy cancellation option via link or code
5. Executes the transaction only if there is no cancellation within 24 hours
This mechanism could be integrated into the existing core banking systems of Greek banks without significant architectural changes [20]. Most modern banking platforms already support similar functions for other purposes, such as processing large transactions or complying with AML (Anti-Money Laundering) regulations.
Protection Against Common Threats
This solution would offer effective protection against the most common forms of cyber fraud:
Phishing Attacks: When scammers steal a user's login credentials through fake websites or emails, the 24-hour delay would give the victim time to realize the scam and prevent it.
SIM Swapping: Even in cases where criminals manage to gain control of a victim's phone number, the delay would provide additional time to discover and address the attack.
Business Email Compromise (BEC): In cases where criminals forge business emails to defraud companies, the delay would allow time to confirm the authenticity of the transfer orders.
Malware and Trojans: Even when malware has infected a user's device, the delay would provide an opportunity to detect and address the threat before the fraud is completed.
Economic Benefits
The financial benefits of implementing this solution would be enormous. Based on current fraud data, the solution could prevent at least 70-80% of successful cyber frauds. This means:
•Saving 14-16 million euros annually from CNP fraud alone
•Protecting thousands of families from financial disaster
•Strengthening confidence in the Greek banking system
•Reducing the cost of managing fraud incidents for banks
•Improving Greece's reputation as a safe financial destination
The Banks' Unfounded Excuses
“User Experience Will Be Affected”
The most common excuse offered by Greek banks is that such a delay would negatively affect the user experience. This excuse is not only unfounded but also insulting to the intelligence of customers.
First, the delay only applies to first-time transactions to new recipients. Regular transactions to known recipients will proceed normally without any delay. Second, most users would prefer a small delay to losing their life savings to a scam.
More importantly, banks in other countries that have implemented similar measures report an increase in satisfaction , not a decrease. Customers appreciate the fact that their bank cares about their security.
“It is Technically Complex”
Another excuse that is often heard is that implementing such a solution is technically complex. This is simply false. Greek banks have already implemented much more complex systems for other purposes.
For example, National Bank has developed sophisticated AI systems for credit risk analysis. Alpha Bank has implemented complex real-time fraud detection systems. Eurobank has developed advanced digital banking platforms. If they can implement all this, why can't they add a simple 24-hour delay?
“The Cost Will Increase”
The third justification concerns the cost of implementation. This is also unfounded. The cost of developing and implementing such a solution is minimal compared to the benefits it would offer.
Greek banks spend millions of euros annually on advertising campaigns. Piraeus Bank alone spent more than 15 million euros on marketing in 2024. The cost of implementing the Sfakianakis solution would be a fraction of this amount.
Furthermore, the solution would save money in the long run by reducing the cost of managing fraud incidents, legal proceedings, and damage to banks' reputations.
The Truth Behind the Excuses
The real reason behind the inaction of Greek banks is not technical or financial. It is a matter of priorities and culture. Bank managements have chosen to prioritize their own operational convenience over the security of their customers.
This attitude reflects a deeper culture of indifference that characterizes the Greek banking sector. It is the same culture that led to the banking crisis of 2010, and that seems to have not changed despite huge investments in “transformation.” It is the same culture that led to an increase in bank charges for ATM transactions.
The Role of Regulatory Authorities
The Bank of Greece: Silence That Costs
The Bank of Greece, which has supervisory responsibility for the security of the Greek banking system, appears to be failing to exert sufficient pressure on banks to adopt effective protection measures, despite the alarming figures it publishes on bank fraud.
The BoG could issue regulatory directives that would oblige banks to implement delay mechanisms for first transactions. Similar directives have been issued in other countries with excellent results. The BoG’s silence on this crucial issue is not only inexplicable but also dangerous.
The National Cybersecurity Authority: Weak Response
The National Cybersecurity Authority (NCSA) also has responsibilities in the field of protection against cyberfraud. However, its action seems to be limited to general recommendations and information campaigns that have proven insufficient.
The EAC could work with the BoE to develop mandatory security standards that would include delay mechanisms. Instead, it seems to prefer “voluntary compliance” – an approach that has failed miserably.
International Pressures and Opportunities
The European Central Bank (ECB) has expressed concerns about rising levels of cyber fraud in the Eurozone. Greece could emerge as a pioneer in adopting innovative security solutions, gaining international recognition and strengthening its position in the European financial system.
Instead, our country risks becoming known as one of the least safe financial destinations in Europe – a reputation that will have long-term negative effects on the economy and investment.
Conclusions: Time for Action
A Simple Choice
The situation is crystal clear. On the one hand, we have a proven effective solution that is being successfully implemented in dozens of countries worldwide. On the other hand, we have Greek banks that persist in practices that expose millions of citizens to risks.
The solution proposed by Manolis Sfakianakis is not revolutionary from a technological point of view – it is revolutionary from a common sense point of view. It is a solution that puts the security of citizens above the operational convenience of banks.
The Cost of Inactivity
Every day that passes without the implementation of this solution, dozens of Greek citizens become victims of fraud that could have been avoided. Every week that bank managers choose inaction, thousands of euros disappear from the accounts of innocent people.
The cost of this inaction is not only economic – it is also social. It is the destruction of trust in the banking system, the erosion of social cohesion, and the creation of a climate of fear and insecurity.
The Answer We Need
It is time for the Bank of Greece and the National Cybersecurity Authority to stop playing the role of observer and take on the role of protector of Greek citizens.
The solution exists. The technology exists. The international examples exist. The only thing missing is the will to put the safety of citizens above all else.
