5 TIPS TO PREVENUE A MALICIOUS LINK

1. Check Who Sent the Email And To Whom

Malicious links are often found in messages sent from questionable accounts and to a large number of people. This means that you need to check who sent the message and to whom. If the addresses and list of recipients look suspicious or unfamiliar, it probably is and you shouldn’t click on anything in it.

 

2. Be Wary Of The Subject Line

If an email subject line looks sketchy and doesn’t match up with the content in the email, it is probably best to delete it. Therefore, make sure to double-check the source and subject line of the email to make sure it isn’t a phishing attempt

 

3. Check The Content

As we mentioned above, it’s important to check the content of any email you receive that seems even slightly suspicious. Often, in the case of phishing, the email will be attempting to mimic another company that you regularly interact with, so check for any misspellings, especially in the sender’s email address

Other things to look out for include bad grammar and language that doesn’t make sense. This could mean the content was automatically generated for a large-scale phishing scam

 

4. Scrutinize Hyperlinks And Attachments

As a general rule, don’t click any links or open any attachments unless you are absolutely sure who you are receiving the email from.

Many people have been lured into thinking that they are interacting with their bank, when in fact the hyperlinks and/or attachments have contained malware or are attempts to steal their personal information.

However, this can also happen with senders that you know. If you weren’t expecting an attachment or the sender doesn’t usually attach files, it’s best not to click on them ,especially PDF and ZIP files

One easy way to check for dubious hyperlinks is to hover your mouse over the link. If there are misspelled words, a lot of text and numbers, and the link doesn’t quite match up to the hyperlink content, it’s probably a phishing scam

 

5. Be Aware Of The Date And Time

Since many phishing attempts are carried out at scale, it means they will often be sent at odd hours., it’s a good idea to check the date and time of the message
