BEC (Business Email Compromise), also known as business email compromise, is the practice of using email to scam businesses for money or goods. Criminals impersonate business representatives using company names, domains, and logos. Or use compromised email accounts and pretend to be your co-workers. Here are the things you need to know and solutions to secure business email against this form of attack.
BEC Attack (Business Email Compromise)
Common scams related to business email compromise include:
How to prevent email accounts from being compromised?
1. Beware of scams
Phishing is a form of impersonation of individuals or organizations that you think you know or that you trust. Cybercriminals steal logins using phishing techniques and then use those credentials to send malicious content to your contacts. To secure business email, you need to invest smartly in cybersecurity solutions and prepare yourself to be on high alert.
Phishing is not just limited to email. These scams are also carried out via SMS, instant messaging, and social networks. They pretend to be trusted organizations such as:
Reputable organizations will not call, SMS, or email to verify or update your personal information. And certainly companies like Amazon, PayPal, Google, Apple, and Facebook too. When you receive suspicious information from these companies, there are some simple things you should do to keep yourself safe:
Some organizations and companies will have secure pages to identify scams impersonating their brand. If you receive a message that looks suspicious, contact the individual or organization individually to check if they likely sent the message. Note that you should use contact information that you have verified in another way, e.g. get a phone number from the official website of the organization.
2. Use multi-factor authentication and strong passphrases
Use multi-factor authentication so employees can verify their login information when accessing the system and secure business email. Multi-factor authentication is one of the most effective security controls you can implement to prevent unauthorized access to your computer, applications, and online services. Using multiple forms of authentication will make it more difficult to break into your system. Criminals can steal one type of credential, but it's very difficult to steal a combination of multiple credentials in an account.
To implement multi-factor authentication, a combination can be used:
Finally, encourage employees to use biometrics or strong passphrases to lock their devices - especially mobile devices.
3. Design a secure business process
Businesses should design a clear and consistent business process so that employees can verify and authenticate payment claims and sensitive information. Keep employee contact information confidential, especially in departments likely to be targeted by fraudsters, such as accounting, finance, or human resources.
Make sure workers recognize the following warning signs:
The company needs to guide employees in verifying account information, think carefully before making unusual requests. At the same time, businesses need a clear process to report threat requests and take immediate action to respond to attacks.
Protect your business reputation against the risk of being impersonated
Develop and use internal network security controls. Criminals can gain access to any email account by compromising a company's systems. Also, the company might consider registering domain names that look similar to the business's domain name (for example, replace letters like 'l' and 'o' in your organization name with digits like '1' and '0'). This will help prevent hackers from scamming others by using a domain name similar to yours. You can also check for fake business domains by monitoring the certificate transparency log.
If you're a domain manager and email server, implement email verification. SPF and DMARC are measures designed to detect phishing emails by specifying which mail servers are allowed to send emails on behalf of an organization's domain. This will help control the risk of impersonation and ensure business email security.
