Avoiding fraud due to MoMo


Mobile money is a fast, simple, convenient, secure and affordable way of transferring money, making payments and initiating other transactions using a mobile phone and other mobile devices. It is seen as an opportunity to cross-sell financial products, playing an important role in extending financial services to the unbanked and underserved population (financial inclusion) as one does not need a bank account to manage it. The key participants in this service include telecommunication companies, partnering banks or financial institutions, or any other duly registered e-money issuers, agents of these e-money issuers, and users of the service.

Mobile Money, a.k.a. MoMo, has come to be a ubiquitous money in walking banks as it provides convenience in accessing money on the mobile phones of subscribers wherever they find themselves. It has become a key driver in the financial inclusion, branchless and cashless agenda of the Ghanaian economy, and this agenda is gradually also being championed by the Mobile Network Operators/Telecommunications companies (‘MNOs’ or ‘telcos’). Since introduction of mobile money services in the year 2009, the benefits to subscribers have been enormous.

Evolution of MoMo

With Mobile Money, which works like e-money, one can send and receive money safely; pay utility bills, TV Subscription; buy movie tickets, buy airtime; withdraw cash at merchants’ points including ATMs, and pay for goods and services. In Ghana, Mobile Money is operated by 4 major Mobile Network operators, MTN (MTN Mobile Money) –industry leader; Tigo (Tigo Cash); Airtel (Airtel Money); and Vodafone (Vodafone Cash), which has grown from a transaction value of GH¢594million in 2012 to the multi-billion-  cedi sector it is now. Also, introduction of third-party technology infrastructure in the MoMo services sector has enabled transfer of funds to and from bank accounts through MoMo platforms.

The Bank of Ghana’s Payment System Statistics on Mobile Money in Ghana revealed the constant growth of MoMo services, as depicted in the table below, makes explicit the phenomenal growth of MoMo in the country.

According to a study on financial inclusion conducted by the World Bank’s Consultative Group to Assist the Poor (CGAP), Ghana’s progress on mobile money is commendable, especially as the service was introduced barely half a decade ago. According to CGAP Ghana is “the most digital financial services-ready country in Africa” when it comes to the key elements required for successful adoption: 92% of adults have the required ID necessary to open an account, and 91% of Ghanaians already own a mobile phone (compared to only 74% and 72% in Kenya and Tanzania, respectively). The flipside to this sheer volume of subscribers and transactions is the increased risk of fraud due to growing expansion in ‘walking banks’ – MoMo

MoMo Fraud

Fraud in the context of mobile money can be said to be intentional and deliberate actions undertaken by players in the mobile financial services ecosystem, aimed at deriving financial gains, denying other players revenue, or damaging the reputation of other stakeholders. The occurrence and prevalence of fraud is dependent on the stage of implementation for the mobile money service. Thus, as deployment evolves the various types of fraud evolve with it (Mudiri, 2012; Gilman & Joyce, 2012).

Types of mobile money fraud

MoMo fraud is often perpetrated by “psychopathic and sociopathic snakes” or fraudsters in the full glare of the day in a web of byzantine nature, plaguing further development of the service and duping a lot of unsuspecting subscribers – robbing them of the joy in using this smart way of transacting business. Most of these fraudsters or tricksters register as MoMo agents/vendors.

The Ghana Chamber of Telecommunications, in April this year, said mobile money operators in Ghana – namely, MTN Mobile Money, Tigo Cash, Airtel Money and Vodafone Cash – have recorded 388 money fraud cases in 2016 as against 278 in 2015.

Various sums of money have been made away with by the fraudsters; the majority of these cases have been reported to the police for further investigations and some have been successful, as suspects have been tried and convicted for their fraudulent actions. Victims of MoMo frau – who have suffered from these tricksters with monies ranging from GH¢70-GH¢4,000 – often describe their experience as unfortunate.

The approaches to fraud executed by tricksters demonstrate their thorough understanding of the mobile money system and the lacuna in the processes in place after patiently studying the behaviour of both customers and agents. Due to the recent hike in fraudulent activities by some unscrupulous persons and confidence tricksters in MoMo services, it is imperative to be alert to the schemes used by these persons. And with the fast-increasing adoption of mobile money services, an increasing number of di­fferent fraud types are known to occur. Some of such possible key fraud threats and avenues to MoMo Services used by these unscrupulous persons include:

Scam Messages/Reversal of erroneous transactions: These exploitative persons (fraudsters/tricksters) send Mobile Money scam messages to subscribers with the intention of tricking them into sending funds to a designated number. Some of these tricksters use different SIM cards and phones to perpetrate their fraudulent acts. Fraudsters often resort to sending fake SMS messages to subscribers’ phones (smishing) or email (phishing), alerting the customer of a cash in transaction on his mobile money wallet.

Shortly thereafter, the fraudster calls the customer claiming to have erroneously sent money to a wrong customer number. Innocently, and before checking the balance on his/her mobile money wallet, the subscriber makes a transaction to reverse the “erroneously sent money” from his account – thus losing money.

This fraud is also perpetrated in the form of cooked messages from fraudsters bearing a supposed source from the service provider requesting you to change your PIN and reply by texting the old PIN and desired new PIN to the sender – from whence the fraudsters use your PIN at their discretion to make unauthorised withdrawals.

Emotional Delusional SMS: The fraudster sends an SMS seeming to have originated from the Mobile Money Service Provider (MNO). The fraudsters will then call and tell the recipient that the fraudster’s mother is sick at hospital, he/she wrongly transferred some amount to your wallet instead to his/her sister at the hospital. The Fraudster then asks for the money to be returned to a named number, and under the guise of emotional sympathy the subscriber sends money without having verified the SMS’s authenticity.

Anonymous calls from fraudsters: Customers receive calls from fraudsters after deposits, to transfer funds received with the claim being that airtime has been wrongfully sent to the subscriber – and oftentimes this is not cross-checked before (supposedly) resending by subscribers.

Cash-out Fraud: Customers are pushed by a payment approval prompt and lured to enter their pin code in order to receive a prize won through Mobile Money, and are then tricked with an authorisation SMS.

Vendor PIN Fraud: This type of MoMo fraud is usually targetted at MoMo agents, especially those who have high customer traffic. It is common practice for these busy MoMo agents to initiate a transaction and then hand over his phone to the customer to punch in his number. The customer then gives the phone back to the agent to complete the transaction by inserting in his PIN code.

Fraudsters take advantage of this. They go to the agent in the guise of a normal customer wanting to process a transaction, and follow the usual process. During this time, the fraudsters study the buttons pressed by the agent for his PIN code. After a few visits to the agent, the fraudsters can usually identify the agent’s PIN code as it is a 4-digit password.

The fraudster then goes to the agent to transact. This time when the agent hands over his/her phone to the supposed ‘customer/subscriber’, the fraudster quickly punches in a phone number, inserts the agent’s PIN code and completes the transaction. The fraudster then starts another transaction to cover his/her tracks and hands the phone back to the vendor/agent to complete the genuine transaction.

False Promotion: This is a new tactic devised by tricksters. It works like an advance-fee fraud. These tricksters run on the ambit of the fierce competition in the telco industry that has precipitated price-wars, bonuses on airtime top-ups, and special prizes under loyalty programmes which include Cash, Cars, Refrigerators, Houses among others. Winners are alerted through telephone calls asking them to pick up their prizes.

The fraudsters are responding quickly by creating their own ‘call centres. Posing as staff from the telco, these tricksters call subscribers informing them that they are lucky winners of bogus packages and should come quickly to redeem their prizes. However, they request the subscriber (their “lucky winner”) to make an initial deposit of mobile money to facilitate the process of handing over the prize. Also, customers can be lured to authorise cash-out transactions with the claim of winning a Mobile Money promotion.

Fortuitous Scam: Fraudsters call to dupe customers under the pretext of delivering goods from abroad (Vishing), which the subscriber never expected.  Some fraudsters call and ask for specified amounts to be deposited into a mobile money account, in exchange for these goods from supposed relatives/friends abroad.

MNO Fraud: This type of fraud is usually perpetuated by the mobile network operator (MNOs) or service provider’s employees. The victims of this type of fraud include the service provider, merchant, agent or the customer. Examples of this fraud include the service provider stealing customer’s electronic cash; unauthorised transfer of funds from a customer’s account; and collusion between fraudulent mobile money employees and other fraudsters to carry out unauthorised SIM swap and transactions from customers’ mobile money wallets.

Employees also engage in identity theft/fraud by accessing and exploiting customer information without authorisation. Many incidents of this type of fraud have been reported in news media across other African countries. Fraud situations for mobile network operators (MNOs) can be high; yet because of MNOs’ non-disclosure, the extent of fraud with mobile money is unknown.

MoMo Fraud Prevention Tips

For businesses and individuals alike who are merchants, customers or subscribers to MoMo services, it is imperative to stay alert and put in place measures which mitigate MoMo fraud.

Do not share your pin number with vendors/agents: Your PIN (Personal Identification Number) is like your password or secret code for processing of transactions. Your PIN should not be made known to the vendor or agent during transactions, as this puts you at risk of fraud due to MoMo. No vendor or agent has the right to demand the private PIN numbers of customers when performing a function on the mobile money platform – and if you think someone has seen your PIN or it has been compromised one way or another, change it immediately.

Protect your PIN: Ensure you do not chose easy-to-guess pin codes as your PIN numbers: like Date-of-Birth, Year-of-Birth, Car Number Plates, Post Office Box addresses – since third parties can easily break through. Additionally, memorise your PINs. Do not write them down or note them on your phone or in an app on your computer; or tell anyone what they are; and always remember to shield your keypad when entering your PIN at any Agent point during transactions. You are encouraged to change your PIN at least every 3 months.

Confirm the identity/name of receiving subscriber: Do a due diligence (verification) of the name on the account you are sending funds to. Don’t be outwitted by someone who says he has sent money mistakenly to your account. Even if you believe their story, please check your balance before you proceed to do any transactions. Pay attention when doing your transactions. Make sure what you type in is the name you want to type in.

The commonest trick used by these tricksters is they call pleading they have mistakenly sent you some money, so then ask you to resend it immediately. Unfortunately, many fall for this without cross-checking their account balance before responding to such calls; or check if the payment alert received earlier has the same transaction ID number as that of deposit on account confirmation.

Don’t Let Anyone Carry Your Phone to Withdraw Money for You: Avoid the practice of sending third parties to cash-out monies on your behalf. Some of these third parties may include friends, boyfriends, and girlfriends among other relations, who could easily monitor your transactions and divert funds to other mobile money account numbers. Even if you want to send someone, ensure that you change your PIN when the phone is returned to you. If you are a vendor/agent, ensure that you make an end to end transaction by yourself and avoid customer contact with agents’ phones.

Check your balance after every transaction: Check and record your balance after every transaction is completed. Also, check your account balance when you receive a suspicious message. You can also call the MNO call centre to verify if the number that called you is the genuine owner of an unallocated mistaken money, as there could be a genuine incidence of wrongful money receipt. Vendors should ensure records of all transactions are made, with balances after every transaction recorded so that an audit trail can be made.

Ignore suspicious calls or messages: Kindly ignore such calls and messages when you suspect them to be of a fraudulent activity. Report it to the telecommunication company to follow up and deal with the issue. The Telecommunications companies (telcos) are working closely with the e-crime bureau and the Ghana Police to clamp down on these criminals when reported.



The telcos are doing a lot to create awareness on the schemes of these tricksters by running campaigns and SMS broadcasts to educate customers on how to differentiate authentic messages from mobile money payment systems and fake ones sent by fraudsters, as the key control lies in the approval of transactions. Although this deters some of the fraudsters, some of them also are evolving tactics with technology.

The fraud schemes are gradually evolving with tricksters’ sophistication in technology and transformation, due to the rising awareness of their antics to subscribers by the telcos. In interviews with selected MoMo merchants and subscribers of the leading mobile money provider, MTN, they concur that mitigating or eliminating MoMo fraud is a serious task for them – and note that as MNOs continue to collaborate with security agencies and build internal systems that audit and check fraud, customers must be on high alert to MoMo fraud schemes.
