While some may jokingly (or not-so-jokingly) call for less email usage and more frequent use of the phone to communicate important information, it’s not always possible in our highly digital world. So in addition to being cautious about what is communicated in your emails, it’s important to understand how to protect those emails in the first place. To ensure secure email on your personal and work devices, you first have to recognize threats to your email system—including the less common ones.
Here are five often overlooked threats to your email security:
- Social engineering schemes that use your mobile number—Did you know that attackers only need your mobile number to trick you into giving access to your email? Essentially, they’ll send you a text posing as your email provider (e.g., Outlook) and tell you you’re about to receive a code to ensure your email account is secure. This text will then ask you to reply with the code to confirm. Then, they’ll trigger the password reset process, you’ll receive a real message with the unlock code—and if you send it to the attackers unknowingly—they’ll use it to reset your password without your knowledge.

- Sharing your access credentials with others—It’s common for some employees to share their credentials—including their password—with a fellow employee or manager when they’ll be out of the office, whether on vacation or during short-term or long-term disability. If organizations don’t have defined security policies for these situations, a lack of accountability could lead to compromised email security.
- Loss of a phone with pertinent information—Password management applications are wonderful tools that help you keep track of all the passwords for all of the email accounts you undoubtedly have. But if this application is installed on a phone that is lost or stolen, that can be a problem. Of course, it’s important that your phone is also password-protected, but organizations should take security one step further when it comes to work or personal devices that carry business data or information. Specifically, a business should standardize acceptable use policies regarding the local storage of files, remote wipe capability and network connectivity.
- Lack of email encryption—Just because data is passed via a secure email server doesn’t mean it’s 100 percent safe. To add an extra layer of protection, companies should invest in an encrypted email service, which seals email messages and ensures only those with a decryption key can read and access sensitive information.
- Crypto-ransomware—Ransomware is nothing new, but it’s a nasty way for hackers to operate. They essentially take the files on your computer or devices hostage until you pay a ransom to have them released. Crypto-ransomware is even nastier, as the hackers encrypt your computer’s files and will only surrender decryption keys upon payment. How is this related to email? These attacks are typically triggered through the opening of some sort of email attachment (e.g., an invoice, energy bill, image, etc.) and they often look legitimate. According to Symantec’s 2015 Internet Security Threat Report, attacks of this nature are highly profitable (bringing in approximately $34,000 per month for one group alone) and growing in popularity.
Whether through phishing schemes or direct malware attacks, email security threats are prevalent—and as we’ve seen, even the mighty can fall prey to them. That’s why it’s more important than ever for organizations to invest in a secure email service that will help them keep their data safe. In addition, employee education is a large part of maintaining a secure email environment. When people know what to expect, they’re better equipped to protect themselves and their companies from liability.
