Revealed: mPoS Devices at Risk from Hackers

Researchers have found that most popular mobile point of sale (mPoS) devices which accept chip-and-pin cards contain several vulnerabilities,
Jon Butler, head of research at MWR InfoSecurity, and a researcher named Nils, studied six of the most popular mPoS, according to their presentation at the annual Black Hat security conference recently.
A patch has been available since April but hasn’t been widely applied, leaving many devices vulnerable.
They uncovered vulnerabilities in the device’s firmware update process.
Butler and Nils were able to look at the USB interface and gain access to the device’s command line to execute commands.
A stack-based buffer overflow bug in the EMV parsing library also opened up the devices to be fully compromised and under the attacker’s control.
They found hints that mPoS could also be compromised via a smartphone infected with malware.
These vulnerabilities, according to the researchers, would not allow attackers to clone the chip on EMV cards.
Attackers can take the available information and the captured PIN to create a cloned card that could be used where EMV is not as widely deployed, such as the United States.
The researchers successfully used a maliciously crafted EMV (chip and pin) card to install and run a Flappy Bird-like game on the device.
A real world version of this attack would likely involve the attacker using a rogue card to modify the mPoS to stealthily copy card details and PINs of every payment card it processes.
The attacker could later return with another card to extract the harvested information.
Chip cards should not be considered trusted, Butler said. Every card has not been freshly issued by a bank, he warned.
These mPoS devices have a small screen, a card reader, and an input pad to accept PINs.
Even though they may look entirely different, Butler said 75 percent of the devices actually are the same when considering the underlying software and tools available.
These devices generally run Linux, or a variant of, and communicate via Bluetooth with smartphones.
The platform vendor was cooperative when Butler and Nils reported the vulnerability and released the patch for the EMV library in April.
There was some delay in releasing the patch because the modified library had to be re-certified again.
“Legal standards actually make it difficult for manufacturers to release security patches in a timely manner. Some of the mobile device vendors have not yet released the firmware update containing the new EMV library”, Nils said.
Unlike many embedded devices, mPoS can potentially be updated easily, as the firmware can be pushed over Bluetooth by the mobile app.
“Even with the uncovered flaws, mPoS devices are potentially more secure than traditional PoS devices”, Butler said.
“They are simple enough that so long as implementation follows security best practices, there’s not much that can go wrong”, he said.

CBN’s New Cash Policy: A Welcome Liberalisation or a Risky Retreat?

By Blaise Udunze
On December 2, 2025, the Central Bank of Nigeria (CBN) announced a policy that significantly departs from the cash-restriction measures Nigerians have faced lately. The apex bank abolished restrictions on cash deposits. Increased the weekly cash withdrawal limits to N500,000 for individuals and N5 million for corporates while substituting the earlier monthly limits of N5 million and N10 million respectively. These modifications, which will be effective from January 1, 2026, represent what the CBN describes as the necessity to “streamline provisions to reflect present-day realities.”

CBN
Authorized by the Director of Financial Policy & Regulation, Dr. Rita I. Sike, the policy overhaul aims to lower cash-management expenses, improve security, and lessen money-laundering threats related to Nigeria’s significant dependence on physical cash. Daily ATM withdrawal limits stay fixed at N100,000 and count toward the total cap. Withdrawals exceeding the limits incur charges of three percent for individuals and five percent for companies, with the revenues divided: 40 percent to the CBN and 60 percent to the banks.
This update comes three years following the disputed 2022-2023 cash redesign crisis at a time characterized by extreme cash deficits, extended lines at banks, and devastating impacts on the informal economy. Consequently, the newest order generates responses: praise from individuals who consider it delayed aid, disapproval from those perceiving it as a bewildering backtrack, and concern from those apprehensive about potential enduring hazards.
Experts Applaud a More Realistic Modification
For economists, in a publication by Nairametrics showed that the action taken by the CBN signifies much-needed practicality. Dr. Salisu Ahmed, an economist based in Abuja, refers to the updated limits as “a step,” praising the CBN for gaining a clearer insight into “cash management practices in a predominantly informal economy.”
He stated that the changes will alleviate the difficulties faced by families and small enterprises due to restrictions. Rigid withdrawal caps had limited transactions, made small-scale commerce more difficult, and caused numerous businesses to experience cash-flow problems. “This adjustment signifies a response from the CBN recognizing the challenges Nigerians face daily and easing rules that previously hindered commerce and individual management,” he clarified.
Banking analyst, David Omale, echoes this view, seeing the CBN’s action as a sign of responsiveness. He points out that higher limits could “enhance liquidity for firms facing challenges from inflation, supply-chain issues and unpredictable cash flows.”
In an economy in which over 60 percent of trade is informal and where the adoption of digital payments varies across different socio-economic groups, experts suggest the updated limits correspond more accurately to real-world conditions. These limits offer businesses flexibility to reinstate transactional liberty and may help recover public confidence diminished by previous cash shortages.
Critics Caution About Continuing Disparities and New Threats
However, the praise is not universally shared. Numerous specialists and industry participants contend that the modifications, although appreciated, are inadequate or might even be detrimental.
Financial strategist Nnenna Okafor contends that the updated limits are insufficient for traders and micro-businesses that depend largely on cash to sustain their operations amid challenges. Due to increasing product prices, logistical difficulties, and unreliable digital banking services in regions, she asserts that numerous Nigerians will still need more liquidity than the new thresholds to stay viable.
Within PoS operators’ players, in Nigeria’s payment system, the response is notably divided.
PoS Operators Split
Certain PoS agents appreciate the modifications, anticipating that they will:
– Reduce friction with banks over “flagged” transactions
– Facilitate processes for clients requiring withdrawals
– Rebuild trust after months of cash shortages
Others convey concern. A PoS operator in Lagos cautions that greater cash availability could hinder the adoption of payments. “While easier access to cash can address problems, it may also decrease dependence on PoS terminals and other digital payment solutions that provide long-term security and efficiency,” she remarked.
She argues that if the CBN does not combine the policy with targeted incentives to encourage payment uptake, Nigeria runs the risk of regressing into deep-rooted reliance on cash.
Another operator in Abuja points out a different issue that has to do with unstable cash supply at numerous commercial banks. He insists that simply boosting withdrawal limits does not automatically fix supply shortages. “If banks cannot consistently provide cash, raising limits fails to solve the issue,” he stated.
Other operators also caution that the new setting might push fintech firms out of the market, which possibly allows monopolies to form since only big payment firms can endure the transition back to increased cash usage.
Experts in Security Alert to Increasing Threats, from Crime
Apart from operational issues, security experts have expressed concerns about the dangers linked to greater cash flow.
Abas Ogendengbe, a security expert at Anold Consulting Ltd., warns that increased access to amounts without strict controls “opens up risks for theft, fraud and money laundering.” He contends that without improvements in surveillance transaction tracking and reporting frameworks by banks, criminal groups might take advantage of the restrictions.
Nigeria continues to confront:
– High rates of petty theft
– Organised criminal cash-for-goods networks
– Ransom-based criminality
– Fraudulent cash-flow manipulation
He contends that a policy boosting the amount of currency in circulation should consequently be accompanied by enhanced institutional protections, rather than diminished ones.
Advantages of the New Policy: Relief, Liquidity, and Business Freedom
Although it has faced criticism, the CBN’s decision carries benefits:
1. Increased Liquidity for the Informal Sector
Small-scale merchants, farm producers, haulers, craftsmen, and market participants relying significantly on cash will experience ease in transferring money, purchasing stock, and expanding their businesses.
2. Reduced Transaction Friction
Companies that once faced limiting restrictions now recover agility, enhancing business continuity and lowering administrative challenges.
3. Restoration of Public Trust
After the trauma of the cash scarcity era, easing restrictions may slowly rebuild confidence in the banking system and encourage more people to save and transact through formal channels.
4. Policy Simplicity
The updated limits, while still restricted, are more straightforward and less administrative compared to the special-authorization system.
The Disadvantages: Policy Volatility, Inflationary Risks, and Stunted Digitalisation
Nonetheless, the policy change is also accompanied by drawbacks:
1. Weakening of Monetary Policy Credibility
Regular significant reversals indicate instability and undermine confidence. A central bank needs to be consistent and foreseeable; Nigeria’s policy environment has shifted in the contrary.
2. Potential for More Money Laundering
Unlimited cash deposits and increased withdrawal limits are inconsistent with standards for preventing illegal financial transactions.
3. Undermining Digital Payment Growth
The increase in fintech was expedited amidst cash availability. A return to reliance on cash might hinder innovation. Dampen the use of safer trackable digital methods.
4. Increased Risk of Robbery and Cash-Based Crime
An increased amount of cash in use results in tangible currency to be stolen additional opportunities for criminals and amplified operational difficulties for the police.
5. Higher Costs of Cash Management
The processes of currency production, circulation, and safeguarding place financial strains on the banking sector and the CBN.
Policy Details and Operational Complexities
The CBN’s circular offers instructions for operations:
– Excess withdrawal charges:
3 percent for individuals
5 percent for corporates
– Revenue sharing:
40 percent to CBN, 60 percent to banks
– Withdrawals from ATMs and PoS terminals contribute to the limit, highlighting the importance for customers to monitor where their withdrawals originate.
– ATMs can now be loaded with all denominations, although third-party cheque cashing is still limited to N100,000.
– Exemptions are maintained for government revenue accounts, microfinance banks, and primary mortgage banks.
– The removal of exemptions for embassies and donor agencies is a move that some parties consider diplomatically risky.
The CBN frames this policy change as a balance, boosting liquidity while still maintaining the nation’s goal of a cashless economy. Nevertheless, its effectiveness depends on the ability of the government and financial institutions to encourage payments while addressing the security challenges posed by greater cash circulation.
A Relief Today, a Question Mark Tomorrow
The CBN’s updated cash-policy structure provides support for families, small enterprises, and the informal sector. It addresses some of the severe effects of previous policies and shows a readiness, though delayed, to adjust to practical realities.
However, the enduring consequences are complex. The policy creates openings, as money laundering hampers progress in payments, increases security threats, and shows a regulatory environment grappling with achieving stability and trustworthiness.
Nigeria is at an intersection. While cash can relieve hardships, it cannot shape the future economic landscape. The current task is to apply this policy without hindering progress, undermining financial integrity, or jeopardizing monetary stability.
The question of whether this constitutes a liberalisation or an expensive withdrawal will in the end hinge on a single element, the CBN’s ability to pair increased liquidity with stronger oversight, steadfast policy direction, and sustained digital-payment incentives.
Only then can Nigeria avoid sliding backward and instead build a financial system that truly reflects the realities of its people, its economy, and its future.

Senate Considers Bill to Empower CBN to Regulate Fintech

Senate on Thursday began debate on a bill seeking to amend the Banks and Other Financial Institutions Act (BOFIA) 2020 to empower the Central Bank of Nigeria (CBN) to designate and supervise systemically important non-bank financial institutions, particularly major fintech operators whose activities now constitute critical national infrastructure.

Leading the debate, Tokunbo Abiru, sponsor of the bill and chairman of the Senate Committee on Banking, Insurance and Other Financial Institutions, said the amendment had become urgent due to the rapid transformation of Nigeria’s financial ecosystem and the emergence of large technology-enabled service providers operating at a scale previously unseen in the country.
Abiru noted that fintechs such as mobile money operators, payment service banks, wallet providers, digital lenders and switching companies now serve tens of millions of Nigerians, process huge daily transaction volumes and hold vast pools of sensitive financial data, yet operate within a regulatory framework that has not fully evolved to match their systemic importance.
“The reality today is that a non-bank institution, because of its market dominance, data concentration, customer reach or technological capacity, may pose risks equal to or even greater than those posed by a traditional bank,” Abiru said.
“We are therefore confronted with a regulatory gap that leaves critical parts of the financial system operating outside the highest tier of statutory oversight. This bill seeks to correct that mischief.”
He warned that without modernising BOFIA, the country risked exposing itself to data insecurity, foreign control of sensitive financial infrastructure and vulnerabilities that could undermine national security.
The senator stressed that many fintechs operate across foreign-owned networks, store customer data offshore, or use cloud systems outside regulatory reach, raising concerns around data sovereignty.
“Today, we cannot say with certainty where all the financial and behavioural data processed by some of these institutions is stored, who has access to it, or which foreign jurisdictions may lay claim to it,” he said.
Abiru recalled the temporary CBN restriction on fintech onboarding in April 2024, following issues around KYC compliance, money-laundering red flags and suspicious transactions, a development that, he said, demonstrated the limitations of existing regulatory tools.
The amendment bill proposes five key objectives, including establishing a statutory framework for designating systemically important institutions, creating a national registry of fintechs, empowering the CBN to impose enhanced supervisory requirements, strengthening data sovereignty, and improving consumer protection.
He dismissed suggestions that a new regulatory agency should be created for fintech oversight, arguing that such duplication would fragment regulation and undermine efficiency.
“Fintech regulation is deeply intertwined with monetary policy, payments oversight, prudential supervision, and systemic-risk monitoring, functions that already reside naturally within the Central Bank,” he said.
“International best practice overwhelmingly favours integrating fintech oversight within existing regulators, not creating new bureaucracies.”
Abiru urged the Senate to support the bill, which carries no financial implications under Senate rules.
Contributing to the debate, Adams Oshiomhole, former president of the Nigerian Labour Congress (NLC), shared the experience of how his accounts were once hacked, disclosing that the hackers accessed him through one of the Fintech banks.
Oshiomhole also said the identities of most of the key owners of online operators were not known and might not be held accountable for infractions since there was no law binding them to any commitments.
“I know the directors of our regular banks, but I can’t say the same of these Fintech banks.
“I don’t know the directors of MoniePoint, Opay and all others”, he added.
Oshiomhole further argued that when properly regulated through an enabling law, the operations of online financial institutions would better serve the interest of Nigerians.
Senators unanimously passed the bill for second reading and referred it to its Committee on Banking, Insurance and Other Financial Institutions for more legislative work.
