Recognizing Suspicious Emails and Websites

It’s important to develop a keen eye for recognizing suspicious emails and websites.

• Check the Sender’s Address:Look closely at the sender’s email address. Phishing emails often use addresses that are slightly different from the real sender’s address, such as a misspelling or a different domain name. For example, a phishing email pretending to be from Amazon might use an address like “[email protected]” instead of “[email protected]”.

• Look for Grammatical Errors and Spelling Mistakes:Phishing emails often contain grammatical errors and spelling mistakes, as they are often created by non-native English speakers or by automated tools. These errors can be a red flag that the email is not legitimate.
• Hover Over Links:Before clicking on any link in an email, hover your mouse over the link to see the actual URL. This will help you determine if the link leads to a legitimate website. If the URL looks suspicious or doesn’t match the expected website, do not click on it.

• Be Cautious of Attachments:Avoid opening attachments from unknown senders or attachments that seem suspicious. Malware can be hidden within attachments, and opening them could infect your device. If you are expecting an attachment, verify with the sender before opening it.
