While spam, phishing, and ransomware are shared, we are often unprepared for the other common email security vulnerabilities. This article will discuss how to prevent these attacks and tips for securing your emails. These include two-factor authentication, encryption, and other basic security measures. These measures will protect your email from spam, spam, and ransomware.


Spammers have several ways to get your email; many use third-party systems such as open mail relays and proxy servers. In addition, they spoof legitimate company and bank addresses to contact your personal information. They can also send plain text advertisements for products and services, and the sheer volume of spam can cause a denial of service. In these situations, you should concern yourself with email vulnerabilities and need to protect your email server from spammers by implementing the proper security measures.

The first step in protecting yourself from spam is to set up a safe list. Ensure your emails are filtered and do not include any attachments that might contain macro viruses. Spam messages also contain links that point to Web sites with scripts. Fortunately, the majority of spam messages are safe to delete. There are ways to fight spam, including learning to use filters and manual email client tools. It is also critical to remove suspected junk emails immediately.


Ransomware infections often start as innocent attachments that contain malicious code. These attachments may then encrypt the network, requiring payment. More extensive campaigns may take advantage of vulnerabilities in software or cracked passwords to spread through an entire network. Once inside, ransomware attacks can devastate a business.

The first ransomware attack was known as CryptoLocker, which spread via infected email attachments and important encrypted data on the infected computer. This malware attack was so popular that it affected 500,000 computers worldwide. In an attempt to stop it, law enforcement agencies seized control of a global network of compromised computers and intercepted the encrypted data without the criminals realizing it. Once the ransomware was stopped, law enforcement agencies established an online portal for victims to access their data without paying the ransom.

Directory harvesting

One of the most common vulnerabilities to your email is directory harvesting, a technique spammers use to find valid email addresses. DHA attacks typically utilize a trial-and-error technique to search through a database for email addresses. First, the spammer attempts to find valid email addresses using common initial combinations, first names, and surnames. The list of valuable lessons is then added to the spammer’s list. Because of this, organizations with standardized email addresses are susceptible to DHA attacks.

Using brute-force techniques, Directory Harvest Attacks attempt to find valid email addresses from a list of email addresses. These attacks typically include employee names and internal domains but are becoming more sophisticated. Directory Harvest Attacks may appear first, and the spammer will map out active addresses by analyzing bounce and open rates. Advanced spam filters may not be enough. Instead, it’s best to configure your email security to prevent Directory Harvest Attacks before they happen.


One of the most common vulnerabilities to email is Phishing. This cyberattack involves posing as a legitimate institution and tricking people into revealing personal and financial information. Phishing emails may appear to be genuine messages or attachments from a reputable company, but the link takes you to a fake website. Once you provide this information, cybercriminals can use that data to steal your identity and financial information.

Phishing emails can look legitimate and appear to come from within your organization. Training staff to spot phishing emails and report them to the proper authorities is vital. This way, your organization can limit the impact of these malicious attacks. Here are some tips to prevent phishing emails from reaching your inbox. Phishing emails can be sent to your employees’ email accounts, so you must check if you are receiving them.
