Email fraud - spoof (also known as phishing or hoax)
- A spoof website is one that mimics a popular company's website to lure one into disclosing confidential information. To make spoof sites seem legitimate, thieves use the names, logos, graphics and even code of the real company's site.
- Although they can be difficult to spot, these sites generally ask you to click a link to a spoof website and request you provide, update or confirm sensitive personal information. As bait, they may allude to an urgent or threatening condition concerning your account.
Signs of a spoof email
- There may be a sense of urgency. Example: Your account will be closed or temporarily suspended or you will be charged a fee if you do not respond.
- Advise customers to contact a phone number to verify your card or account details.
- There are embedded links that look legitimate because they contain all or part of a genuine company's name. These links may take you to spoof sites that ask you to enter, confirm or update sensitive personal information.
- There may be obvious spelling errors. These errors enable spoof emails to avoid the spam filters that internet service providers use.
- If you've received one of these emails, please forward it to email firstname.lastname@example.org. As email spoofs continuously evolve, providing us with examples will help our ongoing investigations. Email spoofs can continually evolve, and even slight variations, like differences in the embedded links, will aide our investigations.
- Customers should understand that Citibank will never send emails to customers to verify confidential, personal or account information.
- If you believe your account has been compromised in any way, call CitiPhone immediately at (84 8) 3521 1111 (84 8) 3521 1111.
You can verify that you are communicating with a genuine financial institution by examining the website certificate during a secure session. This will verify the identity of the specific website you are accessing as well as validate that the site is secure and genuine. It also ensures that no other website can assume the identity of the original secure site. Please refer to your internet browser's documentation for instructions on how to view a certificate. Always ensure that you are using a secure website when submitting credit card or other sensitive information. To make sure you are on a secure web server, check the beginning of the website address in your browser's address bar - it should read https://, rather than just http://.
Report the theft of information to Citibank by contacting CitiPhone as quickly as possible at (84 8) 3521 1111 (84 8) 3521 1111.
Web browsers use standard security protocols like Secure Socket Layer (SSL), and Secure Hyper Text Transfer Protocol (S-HTTP) to enable private information to be transmitted safely over the Internet. When you visit a website with the SSL protocol, a secure connection is created between your computer and the website server you are visiting. Once this connection is established, you can transmit any amount of information to the web server safely. In contrast, the S-HTTP is designed to transmit individual messages securely.
For most web browsers such as Microsoft Internet Explorer and Netscape Navigator, a secure, encrypted session will be indicated by a closed padlock or an unbroken key icon that appears in the lower left or right hand corner of the browser window. You should also check the address bar of your browser. If the website address starts with "https://" rather than the standard "http://" then the session is secure.
Some phishing attacks use viruses and/or Trojans to install programs called "key loggers" onto your computer. These programs capture and send out any information that you type to the phisher, including account numbers, usernames and passwords. In this case, you should:
- Install and/or update anti-virus and personal firewall software.
- Update all virus definitions and perform a full scan.
- Confirm every connection your firewall allows.
Digital certificates are issued by extensively audited and controlled certification authorities to authenticate a website or elements of websites. The certificate identifies the originator of the site and verifies that it has not been tampered with. When your web browser is presented with a certificate, it will check to see if a legitimate certification authority issued the certificate. If there is a match, your session will continue. Otherwise, your browser will issue a warning, and your safest action is to cancel your activity.
If a secure session is established and the information is encrypted during transmission, then others will not be able to view your information. However, you should be aware that some web browsers will store information on your computer even after you are finished conducting your online activities; this is called caching. Therefore, you should close your browser once you are finished using the Internet, particularly if you visit secure sites to conduct financial transactions, check account balances or view any other information that you regard as private and confidential.
Email sent over the Internet is generally not secure unless it is encrypted. In reality, most email programs currently do not have this capability. As most email transmissions are not secure, you should never send any personal or financial information, such as your credit card number, over email.
You are recommended to use supported and updated browsers to ensure that your internet banking is secure.
