MTN GH Reveals How Scammers Steal Your Information
Click to Zoom
Let’s be honest with each other for a minute. When money disappears from a Mobile Money wallet, what is the first thing we scream?
“It’s an inside job!” “MTN staff have sold my details!” “How else did they know my name and balance?”
I hear this every single day. As an online safety advocate here in Ghana, I get complaints from people swearing that the telecom giants are conspiring against them. It is a natural reaction. When a stranger calls you, mentions your full government name, and asks you to confirm a transaction you didn’t initiate, it feels like someone on the inside handed them your file.
But I am here to tell you the hard truth today. I recently reviewed a viral security alert from MTN Ghana, and it confirms what security experts have suspected for a long time.
The person leaking your information isn’t a corrupt bubbly lady at the MTN office.
Often, the person leaking the information is YOU. Yes, you heard me YOU!
Today, we are going to break down the mechanics of MTN MoMo fraud tricks. We are going to look at the “Social Engineering” tactics fraudsters use to profile you, guess your PIN, and empty your wallet — without ever needing an insider at the telco to help them.
The Big Myth
Let’s kill this rumor right now. According to the official insights from the security team, MTN staff do not and cannot share your PIN or One-Time Password (OTP) with anyone.
Why? Because they cannot see it.

The system is designed with encryption. When you type those four digits, they are scrambled into a code that no customer service agent, manager, or technical staff member can read. If you call customer care and ask them to tell you your current PIN because you forgot it, they can’t do it. They can only help you reset it.
So, if the staff can’t see your PIN, how do the fraudsters get it? How do they know you just received 500 Cedis? How do they know your name is Kwame and you live in Kumasi?
The answer lies in a technique called Social Engineering. Fraudsters don’t hack the MTN mainframe; they hack people. They hack your habits, your carelessness, and your social media footprint.
How They Build Your Profile
The video transcript from the recent alert highlights a terrifying reality: fraudsters are working harder than you think. They are not just guessing random numbers; they are conducting full investigations into your life.
They are willing to “go through the valleys, the seas, and the mountains,” as the alert says, just to piece together your identity. Here is how they do it.
1. The Social Media Trap
You might think your Facebook or Instagram is just for fun, but for a scammer, it is a database.
The alert pointed out a massive vulnerability: Your Profile Name. Many people, especially on platforms like Telegram, TikTok, or even WhatsApp, use their phone numbers as their usernames or display names. For example, a user might have the handle “User 0244444333.”
Once a scammer sees that, they have your number. Step one is complete.
Next, they look for your Date of Birth. How many of us have our birthdays displayed publicly on Facebook? “Born on 12th May, 1990.” If a scammer has your phone number and they know you were born in 1990, what do you think is the first PIN they will try?
- 1990
- 1205
- 0512
If you are using your year of birth as your PIN, you are practically handing your wallet to them. This is Social Engineering Ghana 101: using public information to bypass security.
2. The Profiling Checklist
The fraudsters are methodical. They build a profile on you before they even make the first call. Here is what they look for:
- Public Phone Numbers: Is your number on your business page, flyer, or buy-and-sell group?
- Family Connections: Do you mention your mother’s name in posts? (Common security question answer).
- Location Tags: Do you post where you live or work?
- Celebration Posts: “Thank God for this new age!” (Reveals your birthday).
By gathering these scraps of information, they can approach you with confidence. When they call and say, “Hello, is this [Your Name]? You were born in May, right?” you trust them because they “know” you. But they don’t know you; they just read your profile.
The Physical Threat
The MTN alert brought up a chilling point about physical theft. We worry about hackers in a dark room, but sometimes the threat is the guy who snatches your phone in traffic or at the market.
When a phone is stolen, the thief doesn’t just want the device; they want the money inside. But they need a PIN. Where do they look?
1. They check your “Notes” App. Be honest with yourself. Have you ever written down your PIN because you were afraid you would forget it?
- “My MoMo Code: 2580”
- “Secret: 1995”
- “ATM: 1122”
If you have a note on your phone labeled “Passwords” or “Pins,” you are doing the fraudsters’ job for them.
2. They check your Contacts. This is a classic mistake highlighted in the transcript. Some users save their PINs as a contact name. You might save a contact as “My MTN PIN” or hide it under a fake name like “Uncle Ben” with the phone number being your PIN. Thieves know this trick. They will search your contact list for keywords like “Home,” “Code,” or “Pin.”
3. They check your Message History. This one shocked me, but it makes sense. The alert mentioned that sometimes when sending money, people mistakenly type their PIN into the “Reference” field instead of the reason for the transfer. That transaction saves in your SMS history. If a thief grabs your unlocked phone, they just have to scroll through your messages to find where you accidentally texted your PIN to someone else.
How They Know How Much You Have
One of the main reasons people suspect an inside job is because the scammer knows their balance. “He knew I had exactly 600 Cedis!”
MTN staff didn’t tell them. The system didn’t leak it. The scammer figured it out using The Balance Probe.
Here is how it works:
1. The Name Check: They try to send you a tiny amount of money (e.g., 0.10 GHS or 1 GHS). Before they confirm, the system shows them your registered name: “Do you want to send 1 GHS to KWAME MENSAH?” Now they have your name.
2. The High-Value Estimate: To guess your balance, they try to initiate a payment from a compromised account to your number for a high amount, or they try to send you a huge amount.
- If the system says “Transaction failed, recipient reaches limit,” they know your wallet level.
- If they try to pull money and the system says “Insufficient funds,” they lower the amount and try again until the network asks for a PIN. Once it asks for a PIN, they know you have at least that amount in the wallet.
It is a game of trial and error, but to you, it looks like magic.
The Strong PIN Guide
Stop being predictable. We all want convenience. We want a PIN we can remember even when we are tired or in a rush. But convenience is the enemy of security.
The transcript was very clear: Do not use your date of birth. Do not use your year of birth.
The Weak PIN Hall of Shame
If your PIN is on this list, it’s time you think about changing it:
- 1980 – 2005: Any year of birth.
- 1234, 0000, 1111: Sequential or repeated numbers.
- Last 4 digits of your phone number: If your number ends in 4333, and your PIN is 4333, you are asking for trouble.
How to Create a Safe PIN
You need a random sequence that means something to you but nothing to a stranger.
- Bad: 1990 (Your birth year).
- Good: Take the last digit of your best friend’s number, the number of siblings you have, and the day of the month you bought your first car.
- Better: Randomize it completely and memorize it.
Never store your PIN on your phone. Not in contacts, not in notes, not in drafts. If your brain cannot hold four numbers, write it on a piece of paper and hide it in a physical book at home — never carry it with the device.
The Golden Rule
Always verify before you act.
The ultimate goal of all these MTN MoMo fraud tricks is to get you to do one thing: Authorize a transaction.
Technology has improved. MTN has introduced layers of security. Scammers can’t just take the money; you usually have to “Approve” it. This is where the “Cash Out” scam thrives.
You receive a prompt on your phone: “Authorize payment of 200 GHS…” Simultaneously, a “call center agent” (the scammer) calls you, shouting that they mistakenly sent you money or that your account is being blocked, and you need to enter your PIN to stop it.
Stop. Breathe. Read.
The Golden Rule is simple: Never approve a prompt you didn’t initiate.
If you are not standing at a merchant or an agent, and you see a cash-out prompt, it is a scam. If you see an approval request for a bill you didn’t pay, it is a scam.
Conclusion
It is comforting to blame the big corporation. It feels better to say, “MTN exposed me,” than to admit, “I used my birthday as my password and posted my birthday on Facebook.”
But as Yhang Mhany, my goal is to help you keep your hard-earned money. The reality is that fraud doesn’t need an insider; it only needs access. And too often, we give them that access through poor security habits.
Protect your PIN. Think before you click. Verify before you act.
MTN secures the network, but only you can secure your handset. Don’t be the reason you lose your money. Stay sharp, stay safe, and let’s make it harder for these criminals to eat.
