What is phishing
These are a fraudulent e-mail messages or web sites from which attackers want to lure users of confidential information such as login accounts, PIN to cards, etc.


How to recognize a phishing

  • With graphic design of the message attackers are trying to give the impression that the message was send by an organization whose clients are attacked. 
  • Text can look like information about non-payment, call for verification of the password validity or its change or as client satisfaction research with a service.
  • In the message text is a link which should look that it is directed to the websites of the organization (bank) but on closer examination you find out that it is linked to somewhere else and there are fraudulent websites.
  • In the browser address line is showed different address than address of the organization whose clients are attacked. Sender address can also be from different domain than websites of the organization (you see it after showing head of an email).
  • Message/form encourages you to share information that would not be required by the organizaton.

Read carefully and use common sense

  • You win one million pounds!
    Did I bet?
  • Pay the bill!
    Did I ordered something?
  • Your inbox is full!
    I greased e-mails last week. Could I really fill inbox so quickly?
  • Send us an additional personal information, otherwise we will ... !!!
    I have no agreement with the organization and I did not want anything.
  • Tell us your password, your administrator!
    At CIT they are far more privileges than I am (an ordinary user).
  • So this is not!
    • Do not write your password on the bottom of the screen and for sure do not tell it anyone.
    • When someone imitate my signature, I will give it a criminal complaint, but the electronic signature that is just such a crazy farce IT guy. Something like a computer game.
