Top 3 Signs of Malicious Emails, New York, New York

Many cybersecurity breaches occur through emails. Cybercriminals load malicious content into messages sent to employees to trick them into downloading malware or ransomware. Educating your team on best practices will help prevent data breaches. Teach them to look for the following signs of potential threats.

How to Recognize Dangerous Emails

1. Unknown Addresses

If you don’t recognize the email address, be on alert. It may be from a person posing as a dummy corporation to request your private information, for example.

It could also be an email claiming to be from a known institution. Companies use private domains that include the names of their organizations. If you receive a business email from a public, consumer domain, it might not be from a real company.

2. Grammatical Errors

cybersecurity-melvilleMany people try to breach cybersecurity systems from overseas. If there are multiple grammatical errors in the message, or if the company name or domain in the email address is misspelled, the information might not be from a reputable source.

While one mistake isn’t necessarily cause for concern, credible institutions don’t typically send out business emails riddled with misspellings and grammatical errors.

3. Links & Attachments

Cybercriminals load malware into attachments. When an employee downloads the file and opens it, the virus is deployed into the computer. Never open an attachment unless you trust the sender. When in doubt, have your anti-virus software or email provider scan for malicious content.

The same goes for links, which can also deploy malware when clicked. These will often urge the recipient to “Click Here.” Unless you see and recognize the web address, don’t click.
