There are many techniques that can be used by individuals, organizations, and service providers. These techniques provide how to protect sensitive information with email communication and accounts from unauthorized access, loss, or destruction.

Individuals can protect their account with the help of creating strong passwords and changing them frequently. They can use alphabetical, numerical, special symbols to make a strong password that helps to protect your account.

By processing and scanning all received emails, email gateways check emails for threats, and analyze that should be allowed into the system or not. A multilayered gateway is a powerful technique since attacks are increasing rapidly and becoming complicated and sophisticated. Some emails that cannot be caught by the gateway, training employees on how to differentiate malicious messages, and properly use email are the best approach, which helps users avoid threatening mails.

This process helps to send email securely and prevent hackers from gaining access to the secret information, even if they stop it. The only intended recipient can view the original information with permission.

Email service providers can also help to enhance security with the help of accessing control standards and mechanisms and establishing a strong password. Additionally, providers should also offer digital signatures and encryption solutions to secure emails in transit and in users’ inboxes. Finally, to protect users from malicious, unrecognized, and untrustworthy messages, service providers should implement firewalls and spam-filtering software applications.

There are many organizations (around 7710) hit by a BEC attack every month, as one out of every 412 emails contains a malware attack. According to the Symantec Internet Threat Security Report, spear-phishing is the most widely used infection vector. Below is given a complete description of these types of attacks:

  • Phishing: A form of fraud in which the attacks are the practice of sending fraudulent communications that appear to come from a reputable entity or person in email or other communication channels. Usually, it is done through the email; phishing emails are used by attackers to steal sensitive data like credit card and login information or to install malware on the victim’s machine.

Obtained by spambots, spam mail recipients have had their email addresses (automated programs), which crawl the Internet to find email addresses. This is the dark side of email marketing in which spammers use spambots to create email distribution lists. Typically, an email is sent by a spammer to millions of email addresses with the expectation that only a few numbers of an email address will respond or interact with the message.
  • Spoofing: Email spoofing is an email message that could be obtained from someone or somewhere other than the intended source. It is a popular strategy that is used in spam and phishing campaigns as core email protocols do not have a built-in method of authentication. And, when people think the email has been sent by a legitimate or familiar source, they are more likely to open an email. Thus, it is a common tactic used for spam and phishing emails. The email spoofing is used with the purpose of getting mail recipients to open emails and possibly respond to a solicitation.
  • Business email compromise (BEC): A BEC is an exploit in which an authorized person or attacker hacks to a business email account and spoofs the owner’s identity to defraud the company, its customers, partners of money.

There are five types of BEC scams on the basis of the FBI, which are False Invoice Scheme, CEO Fraud, Data Theft, Attorney Impersonation, Account Compromise.
  • Spear-phishing: Email spoofing is an attack where hackers target an individual or specific organization to gain sensitive information through unauthorized access. Spear phishing is not initiated by random hackers but attempted by perpetrators to gain financial benefits or secrets information. It is an attack in which attackers send emails to specific and well-researched targets while purporting to be a trusted sender. The main objective of spear phishing is to convince victims to hand over information or money and infect devices with malware.
  • Ransomware: It is a subset of malware that is used to encrypt a victim’s files. Typically, it locks data by encryption on the victim’s system. Typically, it locks data by encryption on the victim’s system, and attackers demand payments before the ransomed data is decrypted. Unlike other types of attacks, the primary goal of ransomware attacks is just about always monetary. Usually, when the exploit occurs, a victim is notified about the attack and is given instructions for how to recover from the attack.
