A fraudulent (a.k.a. spoofing, impostor, or phishing) e-mail is one that has been forged. It usually tricks you into providing sensitive personal information either on the spot (e.g. by replying to the e-mail) or including links to a fake website that tries to get you to disclose personal data or log in.

Do not disclose personal, financial or credit card information to little known or suspect websites.

Beware of Spyware
Beware of Spyware

Spyware is a piece of software inserted in your computer that collects information about you and your Internet traffic. It is stored in your PC (with/without your consent) when you download software, games, screensavers, etc. from the Web. It usually claims to be able to improve your computer's performance.

Spyware can be used maliciously to gain access to your passwords, PINs, card numbers, and Internet browsing history. They can also be used to scan files on your hard drive and slow down your computer by consuming system resources leading to system instability or a crash.

Do not login to Citibank Online while such software is installed on your computer. If you have installed any software that claims to speed up your internet connection, or have additional third-party toolbars on your browsers, then you may be using software that has the ability to track your internet sessions. We recommend that you uninstall such software.
