Corporate Emails Are At Bigger Risk In The Upcoming Years

When designing an email protection plan, there is often no need to reinvent the wheel

It is vital to investigate the current email threat landscape and gain insight into the most recent advanced email attack trends, such as rises in business email compromise, the evolution of financial supply chain breaches, and the emergence of brand impersonation in credential phishing attempts.

Safeguarding confidential information is critical for any organisation, especially for enterprises that do a substantial portion of their business online. While technologies such as firewalls, antiviruses, and similar security software are required to secure information, a great security plan begins with employee involvement. Employees aware of security hazards and their part in combating them will build a human firewall to protect against the growing number of threats in today's Corporate email threat landscape. 

Many of the problems with today's technology stack result from pieces designed before cybercriminals were a problem.

What Are The Most Common Email Threats

To breach a network or steal information or money, hackers generally use the following forms of email threats:

1.Social engineering: Instead of hacking into a system, hackers frequently use email to gain information about an organisation. They accomplish this by convincing employees to take steps that facilitate an attack. As previously stated, email spoofing is a typical social engineering tactic. During a spoofing attack, the hacker manipulates their target by impersonating the person whose email they spoofed.

2.Malware: Malware, including viruses, worms, Trojans, and spyware, is increasingly being used by cybercriminals to attack business networks. After gaining control of workstations and servers, they can access confidential data, monitor user activity, increase access privileges, and perform other criminal activities.

3.Hacker groups with malicious intention: A successful attack on a mail server could allow unauthorised entities to access resources elsewhere on the organisation's network. They can then impersonate individuals and launch attacks.

4.Spam: Email spam is unsolicited or undesired communication delivered in mass over email that is typically used to transmit viruses. Phishing is commonly associated with spam because it uses deceptive strategies to trick people into responding to emails and exposing sensitive information. When spam and phishing attempts come from valid email addresses, the servers hosting those addresses may be compromised.

5.Authorised users who make mistakes: Authorised users may inadvertently transmit sensitive or confidential material to others not authorised to view or access it, exposing the company to embarrassment or legal action.

Enterprises Face A Big Email Security Risk

Attackers utilise a variety of techniques to trick email users into disclosing personal information or giving over money, but the six most common are as follows:

1. Chain Mail

A chain letter, often known as chain mail, is an unwanted email in which users forward messages containing misleading information to one another. Yet, specific chain mail might be hazardous to your organisation. For example, someone could pretend to be from IT and claim that they are getting rid of software licences that aren't being used. Your access to a specific software solution will be cancelled if you do not answer and forward the email to everyone on your team. Most recipients will forward the email to guarantee that they continue to have access to the software, especially if it is critical to their jobs.

Finally, the individual who sent the email accumulates a list of emails and individuals in your firm that they might target.

2. Phishing

Phishing includes someone impersonating an individual they are not to trick consumers into submitting sensitive information. Because of a recent breach, you may receive an email requesting you to authenticate your login. These emails might appear quite convincing at first glance, so employees should make it a habit to check the sender's email address and never react to any email requesting their password without prior permission from IT.

3. Spear Phishing

Spear phishing is a type of Phishing in which a specific person, usually a high-level individual inside an organisation, is targeted. Before sending a spear phishing email, the attacker conducts prior research on the recipient, making spear phishing significantly more effective than conventional Phishing targeting random people. A spear-phishing email will use language that leads victims to believe the sender is legitimate because the attacker has done their study. It is much easier to persuade someone to download an attachment, give money, or provide confidential information in this way.

4. Spoofing

Email spoofing includes convincing someone that they are interacting with a legitimate individual. A fraudster, for example, may pose as a manager or member of the finance team. If the victim falls for the fake, they are far more likely to do whatever the attacker wants, such as clicking on a malicious link to install malware on their device. Spoofing is frequently used as a prelude to a broader attack.

5. Vishing

Vishing is a scam similar to Phishing. However, it employs audio channels rather than text, such as videoconferencing platforms or voicemail. Scammers frequently use phoney phone numbers or pose as supervisors or clients to urge individuals to give money or divulge private information.

6. Malicious Attachments in an Email

Malware attachments are frequently used in phishing operations. Cybercriminals will send a seemingly innocuous email with an attachment. Hackers use fear, greed, or personal interest to persuade victims to open or download the compromised files in the attachment.

How Can Enterprises Deal With Email Risks

There will be risks as long as people utilise email. Consider the following to protect your company and its employees:

●Endpoint protection should be used to prevent malware from being introduced via an email-based assault.

●Regular security awareness training programmes should be implemented to educate users on the most recent risks and what to do if they receive a suspicious email.

●Urge your staff to use strong, difficult-to-guess passwords that are routinely updated.

●Implement multi-factor authentication throughout the organisation. It requires anyone attempting to log in to provide other forms of identification besides their login and password, such as a PIN, one-time passcode, or fingerprint scan.

Employee Education Is The Key To Email Security

When designing an email protection plan, there is often no need to reinvent the wheel. Strong passwords, security knowledge, endpoint protection, and multi-factor authentication, when combined, can prevent the majority of assaults. Recall that your employees are frequently your first and last defence against cybercriminals. If they understand the hazards and how to avoid them, you significantly reduce your attack surface.

IT teams and the organisations that support them should not only educate employees about the dangers of Phishing and other similar assaults, but they should also ensure that they have a security solution in place that can defend their organisation if an attacker successfully hooks an employee. It's evident that cyber attacks aren't going away anytime soon and may expand exponentially as remote work becomes more across the board. The sooner your team teaches employees about the risks of working online, the more protected you'll be from an attack.
