Mobile banking has revolutionized the way we manage our finances, but with this convenience comes a range of risks that we need to be aware of.
Malware and viruses can be transmitted through mobile banking apps, compromising sensitive information.
To prevent this, make sure to only download mobile banking apps from trusted sources, such as the official app store.
A significant threat to mobile banking security is phishing scams, where hackers trick users into revealing their login credentials.
These scams often come in the form of fake emails or texts that appear to be from your bank.
To avoid falling victim to phishing scams, be cautious of unsolicited emails or texts that ask for sensitive information.
Public Wi-Fi networks are another vulnerability, as they can be easily hacked into by cybercriminals.
Using a VPN (Virtual Private Network) can help encrypt your data when using public Wi-Fi.
Weak passwords are a common mistake that can be exploited by hackers.
Use strong, unique passwords for each of your mobile banking apps, and consider using a password manager to keep track of them.

App Security Risks

Mobile banking apps are convenient, but they're not completely safe. Any app that can access your money is a target for scammers.
Mobile banking apps transmit data between your device and the bank's server, giving hackers three access points to potentially breach your data and account: on your device, while the data is in transit, and at your bank's server.
Hackers can use malware-infected apps to gain access to your accounts, even if you don't download a fraudulent banking app. Keyloggers, a type of malware, record all the information you type into your phone, including bank accounts and passwords.
Millions of new types of malware are discovered every month, and you can accidentally download malware onto your device simply by scanning a QR code in public.
To secure your bank accounts and devices, set a secure passcode or use biometric ID, and keep your banking app locked when not in use. Choose a secure password for your bank account that's at least eight characters long and includes a combination of uppercase and lowercase letters, symbols, and numbers.

Phishing and Scams
Scammers use psychology and urgency to trick victims into giving up credentials that offer scammers access to financial accounts. They can even spoof phone numbers to make it look like it's coming from your bank's official number.
If you receive a call or text about a suspicious transaction, don't respond. Scammers will tell you they need to close your compromised account and transfer your money into a new "safe" one. In reality, you're sending your entire account balance to the scammer through a wire transfer, Zelle, or other payment system that can't be reversed.
Phishing emails are another common tactic. They may look like legitimate emails from your bank, but if you click on the link, it will take you to a site designed to steal your information. Even worse, the links in phishing emails could download malware to your device that gives hackers access to your mobile banking app.
To stay safe, never send account details or financial information to anyone via email, text messages, or phone. And beware of any link or attachment in an unsolicited email. If someone reaches out to you claiming to be from your bank, don't engage with them. Instead, call the official number on the bank's website and ask to speak to someone about the issue.
Here are some steps to take if you've been a victim of a phishing scam:
- Alert your bank immediately and freeze your account.
- Update your phone's security software and run an antivirus scan.
- Delete any malicious or unfamiliar apps that you find.
- Check your bank, credit card, and other financial service accounts for charges or changes that you didn’t make.
- Alert the three major credit bureaus — Experian, Equifax, and TransUnion — about the hack and ask for a credit freeze.
- Get a free copy of your credit report at AnnualCreditReport.com. Report any errors or fraudulent charges to your bank and any other impacted companies.
- Sign up for identity theft protection.
Device Security Risks
Device security risks are a major concern for mobile banking users. A lost or stolen phone can become a nightmare, especially if you're a mobile banking user.

Most people save account passwords on their phones or even stay logged into services like their email accounts. This makes it easier for scammers to access your account if they steal your phone.
Using a rooted or jailbroken device increases its vulnerability to malware. Buy phones from official retailers to ensure they have industry-standard security protocols built in.
Always use a passcode or biometric lock on your phone to prevent unauthorized access. Enable remote wipe features in case of loss or theft.
Installing the latest OS and app updates as soon as they become available patches vulnerabilities that hackers can exploit. Don't let your software become outdated.
You can check the status of your Android device by going to settings → status information → phone status. It should say “official.” On iOS, look for signs that your phone is jailbroken, such as with apps like Cydia or Sileo.
Here are some common signs of a malware infection:
- Lower battery life
- Strange messages or texts in your “sent” folders
- Unusual data or cell phone bills
- Performance issues, reduced functionality, and call disruptions
- Applications that you didn’t install
Using a virtual private network (VPN) can protect you from cyberattacks, especially while you’re connected to public Wi-Fi networks.
Malware and Viruses

Mobile banking risks are a growing concern, and one of the main threats is malware and viruses. Millions of new types of malware are discovered every month, and it's estimated that ⅓ of all mobile attacks come from hidden apps that run as a background service once the user closes the app.
Malware can record your actions, capture screenshots, and grab login information, making it a serious threat to your mobile banking security. To date, problems involving viruses and malware targeted at mobile devices have been limited, but the ubiquity of mobile devices makes them a prime target.
Some antivirus companies state that mobile malware keeps growing in scope and complexity, with keyloggers posing a significant threat. Keyloggers can copy a user's inputs, such as passwords and PINs, and many modern devices have built-in security measures to defend against these risks.
To stay safe, it's essential to keep your devices and banking apps up to date, as bank hackers can install malware by taking advantage of bugs and vulnerabilities in outdated apps and devices. Installing an antivirus with malware and phishing protection can also help detect and block malware.

Remote deposit fraud often involves fake checks that look like real ones, making it difficult for even bank employees to distinguish between them. The Federal Trade Commission (FTC) warns that these scams are on the rise.
To avoid falling victim to remote deposit fraud, keep a close eye on your accounts and thoroughly monitor statements. Consider third-party monitoring services that can provide an extra layer of protection by proactively alerting you to potential fraud across financial accounts.
Here are some common signs of remote deposit fraud:
- Frequent deposits or withdrawals from unfamiliar locations
- Unusual transactions or account activity
- Checks that are deposited but never clear
By being vigilant and taking proactive steps, you can protect your mobile banking accounts from remote deposit fraud.
Secure Your Accounts with Strong Passwords and 2FA

You should set a secure passcode on your phone, or use biometric ID like fingerprints or facial recognition, and set it to lock automatically when not in use. This will prevent unauthorized access to your phone and subsequent access to your banking app.
Choose a secure password for your bank account that is at least eight characters long and includes a combination of uppercase and lowercase letters, symbols, and numbers. Avoid using easily guessable information like your name or birthdate.
Use a password manager to securely store your password, and make sure it's unique and not reused elsewhere. This will prevent hackers from gaining access to your account through a breach of a different service.
Add an extra layer of security to your bank accounts by enabling two-factor authentication (2FA). This will require you to enter a verification code sent to your phone or use an authenticator app like Google Authenticator.
