Email privacy: What are the risks?

Email is such a widespread form of communication that we may not always think about its security risks. Nevertheless, email can be one of the biggest threats to data security. Are you aware that the majority of cyber attacks and data security breaches start with an email? Many cyberattacks begin with some form of phishing email, where hackers attempt to gain access to accounts or devices using deception or malware.

A single employee’s mistake in clicking on a malicious link in an email can lead to the entire company’s computer system being infected with malicious software or putting everyone’s emails and personal data at risk.

There are several security threats associated with emailing, including:

1. Phishing: This is when a person or organisation pretends to be a trusted source, such as a bank or a colleague, with the aim of tricking the recipient into divulging personal information such as passwords or financial information.
2. Malware attachments: Attachments in emails can contain malware, such as viruses, ransomware or spyware, that can infect the recipient’s device and cause damage.
3. Illegal access: Inadequate protection of email accounts can lead to unauthorised access, where hackers can gain access to sensitive information, steal identities or take unauthorised actions on behalf of the user.
4. Data interception: Sending sensitive information via e-mail increases the risk that this information can be intercepted by unauthorised parties, especially if the e-mails are not encrypted.
5. Email spoofing: This is when an attacker manipulates the email address of the sender to make it look like the email is coming from a trusted source, which can be used to spread phishing emails or other forms of fraud.

These threats underscore the importance of implementing appropriate security measures, including the use of encryption, strong passwords, two-factor authentication, and ongoing updating and training of users on secure email practices.
