Security Risks Associated With Email

The prime goal of these email attacks is to target people so they can give away their sensitive data or compel them to download malware in their systems.

Hackers cleverly use their access to gain confidential information for their own benefit like selling it on the dark web, using it for identity theft, access financial accounts, or ask for a hefty ransom.

Several bad actors threaten the safety of the email accounts. However, the most prevalent risks and threats include malware, spam, phishing, Trojans, worms and viruses, and spoofed domains. Now, let’s read the risks these threats impose on the victims.

1) Malware

Malware or malicious software often infect computer systems by an external link, vulnerable or infected USB, or download it as an email attachment.

Upon gaining access, malware enters the computer system- corrupts the data, steal sensitive information, as well as mine cryptocurrencies. Attackers also use malware for ransomware attacks in which they hold a computer hostage till the user pays a ransom.

2) Spam

Spam is the unwanted and unnecessary email sent in bulk. Hackers collect email addresses from the customer list, chat rooms, social media, websites, and other compromised address books.

While in some cases, spam might contain phishing links that trick the users so they can provide their confidential information to cybercriminals or other malware sites that download malicious software onto their system.

This problem has become worse in recent latest years and now users are discarding their email addresses instead of combating the problem.

3) Phishing

Phishing attacks are a kind of spam that aims to trick the email recipients into giving their sensitive data or credentials for some malicious reasons- later, the information is misused.

These attacks attempt to utilize social engineering tactics to steal user’s both personal and financial data.

Such attacks are carried out by spoofed emails that provide links to a bogus website that are mainly designed to trick customers into revealing their private data such as account numbers, credit card details, passwords, Social Security Numbers, and usernames.

The perpetrators function by hiding under the phoney identities and names that are stolen from corporate banks, credit-card companies, and online businesses. They can also pretend as banks and government agencies that the recipient might detect.

4) Trojans, Worms, and Viruses

Trojans, worms, and viruses are sent as email attachments. All these destructive codes can easily damage the receivers’ system, change their computers into remote control slaves like botnets that can cause the recipients to lose money and take over the bank and credit card details.

Trojan horse keyloggers are known to record system activities, providing unauthorized external parties access to bank accounts, private business sites, social media accounts as well as other resources.

5) Spoofed Domains

In this type of attack, hackers buy domain names that sound like the brand they want to spoof and pretend to look exactly like the real thing. Unsuspicious email users who click on the link to the spoofed website get tricked into giving their sensitive information.
