THINK before you click, beware of phishing emails!
A phishing email is an email that looks like originating from a reputable institution and that usually contains a request to click on a link to confirm/modify etc.. one's
credentials. In fact this link will bring you to a malicious website that will stole your credentials while you naively insert them.
Here is a short guide on how to avoid being fooled by this type of scams.
1. Always be very suspicious of any emails you receive from trusted entities like the university, your bank etc…
2. Do NOT click on any links given via email.
3. If you really think the email is legitimate, do NOT click on the link but rather write yourself the link
URL in the address bar of your browser. And while you do so, be aware
that a deceptive malicious
URL might be `leidneunv.nl' instead of the correct one `leidenuniv.nl'.
4. Serious institutions (including ours) will never ask you for your credentials.
5. Look out for common phishing language in your emails, e.g. verify your account, confirm your password, etc…
6. Whenever you insert any credentials in your browser, always use https and
always check the information of the SSL certificate by clicking on the padlock at the beginning of the
URL.
7. Change your credentials on a regular basis. On our IL workstations you can do so using the command `passwd'.
8. Contact us if in doubt.
