Email accounts are often targeted by hackers and spammers who send email messages that may contain infected attachments or links.
Spam has become one of the main problems for all Internet users. Spammers usually send an email to a list of one million email addresses and hope that at least a small number of readers will download the attachment or click on the link in the message. Spammers direct the user to open the attachment contained in the email. This attachment is a malicious document that downloads a virus to your computer, so attachments contained in mail or links are dangerous to open and redirect to dangerous websites.
What is especially dangerous are the programs (viruses) that come attached to the email and it is very important to be able to recognize them. Viruses are different from other programs, their names end with extensions EXE, COM, PIF, SCR, VBS, SHS, CHM or BAT. They may also have some of the known extensions e.g. DOC, PDF, HTM, HTML, TXT, JPG, GIF … but behind those extensions are the extensions mentioned in the previous sentence. Never run programs that have EXE, COM, PIF, SCR, VBS, SHS, CHM, or BAT extensions without first scanning with the latest antivirus software.
Be careful when clicking on links that lead to fraudulent sites, however, if you click on the link, do not download or launch potentially dangerous files. Also keep an eye out for possible identity theft.
- Please check the email sender before opening. If you are unsure of the sender, do not open the contents of the email. Even if you have an antivirus program, do not click on the links and do not open the attached files.
- Use the latest version of the antivirus program. Enable automatic software updates, only an updated security program can protect your computer.
- Never reply to a message that you are sure of or consider spam. Delete such message immediately.
- Make sure the URL is secure without clicking on it. If you receive a suspicious URL in an email, hover over it and look at the bottom left corner of your web browser. You should see the correct URL to which you will be redirected. If it looks suspicious or ends in .exe, .js or .zip, do not click on it.
- Poor writing style – The first thing you can notice is the subject and the text of the message. They are mostly written in English. The message may also be in very poor Croatian, which is most often automatically translated from English into an online translator.
- If the email pushes you to download something or click on a link, it’s probably a virus.
To protect yourself from spammers:
- Do not enter the e-mail addresses that you use for business purposes, when registering on various portals, forums where some personal information is required and entering e-mail.
- When sending messages to multiple addresses, put e-mail addresses in the ‘Bcc‘ field, which prevents recipients from seeing the other mail addresses to which the message was sent.
- if you have an e-mail address that you use to receive e-mails sent through forms from your web site, be sure to use web form protection (Captcha).
Be careful when opening attachments or web links contained in a message. If you suspect that this is a virus, do not open the attachments before checking them first.
