Email security risks in 2021 will be discussed in this blog. As online communication becomes more and more necessary, an e-mail will be a significant security problem or, in certain instances, a risk in 2021. Traditional protections, such as the latest anti-virus software, will never prevent cyber-attacks, incredibly advanced social engineering attempts regarding e-mail security.

E-mail security risks are increasing at an alarming pace nowadays. Whale phishing, whaling, ransomware, and other cyber threats have become significant issues for many businesses. Consequently, both big and small businesses must develop methods to mitigate increasing risks to e-mail security. Since more than 90% of cyber-attacks are started by e-mail, the weakest link in the security chain is e-mail. In addition, an infringement of security may negatively affect the image of either the consumer or the business. However, combating attacks by hackers requires a multi-layered e-mail security procedure. One issue is that e-mail is not a secure communication medium by default.

We prepared a list of the ten e-mail security risks most every day in 2021.

Email security risks in 2021

1- Spoofing and Phishing

E-mail spoofing happens when a cybercriminal sends an e-mail to a user masquerading as someone the user knows. E-mail spoofing to the original sender is easy to accomplish and extremely difficult to trace.

Phishing is another hazardous method used to mislead customers into giving cybercriminals personal data like bank accounts or social security numbers. Cybercriminals sometimes add pictures and trademarks that seem more genuine and authentic. They even create a connection that appears natural. It leads users to a fake website, though. As spoofing and phishing are two of cybercriminals’ most common attack techniques, customers need to be informed of the accessible anti-phishing solution.

2- Vulnerabilities in E-mail Security

Vulnerabilities in e-mail services induced by provider misconfigurations need to be identified. When exploiting e-mail service vulnerabilities, they penetrate the target system, expose information, and make the system inaccessible.

3- Domain’s squatting

Squatting is the registration, sale, or use of a domain name to profit from another party’s brand. As a consequence, companies and their customers may become targets for domain squatting and targeted spear phishing.

4-Client-Side Attacks

The channels of attacks against Internet users are increasing every day. A single link with malicious information may capture a computer. The safety of the components of the e-mail service must be enhanced, and anti-phishing measures such as team member training and simulation of e-mail threats must be introduced.

5-Dangerous Files

If harmful information is received from the user via an e-mail attachment, he may take over the whole computer system and network. These files must be examined using an anti-virus and behavioral analysis program based on signatures to guarantee an efficient solution against phishing.

6-Crypto-ransomware

A ransom must be paid once infected to unlock all encrypted data. In this respect, the e-mail service must be strengthened, and the analytical services must be expected to detect and avoid ranking-specific behaviors.

7- Configuration Errors

This is a pervasive security problem. A poorly configured e-mail service may lead to a big issue by enabling e-mail to be delivered without authentication.

For example, a cybercriminal without authentication access to your e-mail service may send a random e-mail to one of your employees. A cybercriminal who embodies the CEO may be more likely to succeed.

8- Browser Exploit Kit

E-mails with known vulnerabilities in the internet browser may lead to identity theft, data leakage, and access problems. Sometimes a link may include an exploited piece of code. In this situation, protection steps must be taken by the e-mail service and security components.

9- Spear Phishing attacks and Business E-mail Compromise (BEC)

Another crucial problem is that a cyber thief who circumvents all security measures uses the ignorance of the end-user to attack the system. Because 97% of the world’s population cannot recognize a sophisticated phishing e-mail. Users should be regularly informed about hazards via phishing tests, exams, surveys, and games.

10-File Format Exploits

Furthermore, file format vulnerabilities have become an essential source of information security threats for an increasing number of companies. Attackers that exploit these vulnerabilities create malicious files that cause application problems (such as buffer overflows). These vulnerabilities are critical since they frequently impact multiple systems. For example, an attacker may create a single malicious PDF file that infects Windows, Macintosh, and Linux systems via a vulnerability in Adobe Acrobat file format.

Solutions to Email Security Risks

To protect against e-mail threats, use specialized anti-phishing technology and:

  1. Use a strong email password
  2. Monitor your email habits
  3. Use two-factor authentication
  4. Look out for “Phishing Emails”
  5. Don’t open attachments without scanning them first
  6. Never access emails from public WiFi
  7. Change your password as often as possible
  8. Avoid giving your email address away
