Emailing bank details may feel convenient, but it can expose you to serious digital risks. Emails can be intercepted by cybercriminals, who can use the information to commit fraud. Even if you know the recipient, they may not have adequate security measures in place, such as end-to-end encryption, which means their email provider can read your emails. If you must send bank details, use a secure email service with end-to-end encryption and recipient authentication. Additionally, use a strong, unique password for your email account and turn on two-factor authentication (2FA) for added security. It's also a good idea to avoid sending sensitive information over public Wi-Fi and to verify the identity of anyone requesting your bank details through another communication channel.

What You'll Learn
Emails can be intercepted by cybercriminals
To protect yourself, it is crucial to be cautious and vigilant. Firstly, assess whether sharing your banking information is truly necessary. If it is unavoidable, ensure that you are using a secure email service with end-to-end encryption and recipient authentication. This safeguards your information by ensuring only the intended recipient can read your message. Additionally, strong passwords are essential for maintaining the security of your email account.
If you need to share sensitive information, consider using a security-focused file encryption tool to password-protect your files before sending them. You can then share the encrypted file as a link and communicate the password to the recipient through a separate, secure channel. Alternatively, you can use services like Dropbox or Strongspace to upload and share files securely. Remember to remove the file from the service after the recipient has downloaded it.
It is always better to be cautious than complacent when it comes to safeguarding your financial information. If you are unsure about the security of your communication channel, refrain from sending sensitive information and explore other options, such as delivering the information in person or via a phone call.

Scammers can pose as trusted people or organisations
It is generally unsafe to send bank information by email. Emails can be intercepted or accessed by hackers, and scammers can pose as trusted people or organisations to trick you into sharing your personal details or banking information. They may use emails that look almost identical to legitimate ones or send messages that create a sense of panic, such as claiming there is a problem with your account.
Scammers often impersonate senior members or trusted employees of organisations to cause harm. They may email clients and customers, asking for payments or changing banking details on legitimate invoices so that payments are directed to their own accounts. They may also pretend to be collecting money on behalf of a charity. Scammers can create fake websites that closely resemble those run by legitimate charities or set up entirely fake charities with convincing names.
Scammers also impersonate trusted businesses, friends, or family members to steal your money or personal information. They can use technology to make their calls or texts appear to be coming from legitimate phone numbers or organisations. They may send messages pretending to be a family member or friend in need of money, sometimes even using real photos to make the scam more convincing. Relationship scammers form romantic or platonic connections with their victims, but their ultimate goal is to steal money from them.
Scammers may also impersonate government organisations or well-known brands to gain your trust and obtain your personal information. They may send emails or text messages with links to log on to online services, which can install malware on your device. They may also threaten you with immediate arrest, deportation, or other legal action if you don't provide personal details or money quickly. It's important to remember that government organisations will not send text messages or emails with links to log on to their services.

Emails are not designed with security as a priority
While email is a convenient tool for communication, it was not created with security as its primary focus. The standard email protocols do not include end-to-end encryption (E2EE), which means that emails can be intercepted by cybercriminals or accessed by unauthorised users. This makes email an insecure form of communication by default, especially when compared to other messaging applications.
Email metadata, such as the sender, recipient, and time of communication, is crucial for the basic functionality of email. However, this metadata is not encrypted, even with the use of additional software like OpenPGP. As a result, even if the content of an email is encrypted, outside observers can still see a lot of information about the message, including who is being emailed and when. This lack of forward secrecy in OpenPGP means that if either the sender's or recipient's private key is stolen, all previous messages encrypted with that key will be exposed.
Email security can be improved by using tools such as OpenPGP, which add end-to-end encryption to messages. However, this still requires careful management and does not fully protect email metadata. Another option is to use a secure email service that offers end-to-end encryption and recipient authentication, ensuring that only the intended recipient can read the message. Additionally, users should follow password hygiene best practices, such as using strong, unique passwords for each account and enabling two-factor authentication (2FA) or multi-factor authentication (MFA) for an extra layer of security.
Despite these measures, the risk of exposing sensitive data through email remains high. Emails can be accessed by cybercriminals if they compromise the email account or device of the sender or recipient. They can then gather all the information inside, including bank details. This often occurs when emails are not protected by strong, unique passwords or when someone physically steals the device. Emails can also be intercepted in transit, with cybercriminals using techniques like man-in-the-middle attacks to eavesdrop or alter data. This is more likely when using public Wi-Fi or an unencrypted email service.

Use a secure email service with end-to-end encryption
It is generally unsafe to send bank information by email. However, if you must, it is important to use a secure email service with end-to-end encryption to protect your sensitive information from hackers and scammers. End-to-end encryption ensures that only the intended recipient can read your message.
One such service is Proton Mail, which offers end-to-end and zero-access encryption. This means that not even Proton can view the content of your emails and attachments. Proton Mail also offers additional features such as an encrypted calendar system and file storage. With over 100 million users, Proton Mail is a trusted choice for secure and private communication.
Another option is Tuta Mail, an open-source encrypted email service from Germany. Tuta Mail combines AES and RSA encryption to secure both the email address and the subject line of message headers. They are also in the process of updating their encryption protocol to add post-quantum cryptography and remove IP addresses from messages.
StartMail is another reliable provider based in the Netherlands. It offers end-to-end encryption for trusted correspondents, and you can protect your address from unwanted emails by using aliases.
For business users, Zoho Mail is a secure email service that provides end-to-end encryption through S/MIME. While Zoho Mail does not support PGP by default, it offers other security features such as two-factor authentication and app-based access restrictions.
In conclusion, while it is not advisable to send banking information via email, using a secure email service with end-to-end encryption can help protect your sensitive data. Proton Mail, Tuta Mail, StartMail, and Zoho Mail are all reputable options that offer end-to-end encryption to safeguard your information.

Avoid sending details over public Wi-Fi
Emailing bank details is generally not safe, but there are ways to mitigate the risks. One of the biggest risks is unauthorized access to your inbox, so it's important to maintain account security. Use a secure email service with end-to-end encryption and recipient authentication to ensure only the intended recipient can read your message. It's also a good idea to use a strong password and verify the recipient's identity.
However, even with these precautions, it's still not advisable to send bank details over public Wi-Fi. Public Wi-Fi networks are often unsecured, exposing you to significant security risks. Cybercriminals can use special software kits and devices to eavesdrop on Wi-Fi signals, allowing them to see your online activity, capture sensitive information, and even take over your accounts.
To protect yourself when using public Wi-Fi, consider the following recommendations:
- Use a Virtual Private Network (VPN): A VPN creates a secure, encrypted tunnel between your device and the internet, safeguarding your data from prying eyes.
- Disable automatic connectivity: Turn off the "Connect Automatically" feature to prevent your device from connecting to unsecured public hotspots.
- Verify network authenticity: Ensure you are connecting to the right network. Hackers may create harmless-looking networks to deceive users and steal their information.
- Turn off file sharing: Keep your files safe from potential hackers by disabling file sharing before accessing public Wi-Fi.
- Use privacy and security browser extensions: These extensions can prevent browser fingerprinting and block cookies, ads, and malicious websites.
- Keep your device updated: Update your operating systems, browsers, and security software to patch vulnerabilities exploited by cybercriminals.
- Avoid sending sensitive information: Refrain from entering passwords, credit card details, and other sensitive data while connected to public Wi-Fi.
By following these precautions, you can significantly reduce the risks associated with using public Wi-Fi and protect your personal and financial information. Remember, when in doubt, it's always best not to send sensitive information via email.
