What is phishing? Phishing is a form of identity theft that is becoming increasingly popular among hackers. They use specially designed websites and fake emails to try to steal your personal data, most commonly in the form of passwords and credit card details.

In unsolicited or phishing emails, you may be asked to visit a website that looks very similar to CIB Business Online, or you may be asked to provide your details. Never provide your login details in such cases!

Here are some tips to help you avoid phishing attacks

• CIB Bank will never ask you to provide your details in an email.
• CIB Bank will never notify customers by email about account blocking or incorrect transactions.
• Always be suspicious of offers that seem too good to be true or messages that contain threats!
• Delete messages that contain a noticeable number of spelling mistakes or ungrammatical words or sentences, as they have definitely not been sent from the CIB Bank system.

• Before logging in, always type the URL into your browser manually or open it from your favorites, and check that the address bar is green and that the certificate is valid.
• Do not reply to unsolicited or phishing emails.
