Do not disclose your card numbers, usernames or passwords to anybody. They should always be memorized and not recorded/written down anywhere. If you need to write them down, make this information encrypted, preventing others from accessing it.

Do not store your passwords in files stored on your computer. Use strong passwords (e.g. never use your birthday date for your password) and change them regularly.

ADDITIONAL SECURITY


Protect your passwords, PINs and account information

  • Change your PINs and passwords as often as you can.
  • Do not share even One-Time PINs to anyone.
  • Make sure that your password is not based on your personal information. Use combination of at least six characters and cases, without repeating any digit or character more than once.
  • Use separate passwords for online banking websites and non-banking websites.
  • Do not save your sign-on information when logging on through public computers and ensure that no one is watching you while you key in your username and password.
  • Clear your browser's cache and history after each session.
  • Always log off properly by clicking the "Logout" button at the top of the screen. Do not just close your browser.
  • Deactivate the "auto complete" function of your browser and never select the auto save option on browsers so that your usernames and passwords are not saved when logging in.
  • Create a back-up of all critical files so you may refer to these in case your account or your identity has been compromised.

Use software protection

  • Install anti-virus, anti-spyware and malware detection software, and update these regularly. The best defense against computer attacks is preventative software so make sure you regularly scan your computer for viruses before logging on to any website.
  • Install a personal firewall to help prevent unauthorized access to your home computer.
  • Do not install software or run programs of unknown origin. While software can claim to improve your computer's performance, it could also be spyware which collects your information without your consent.

Beware of scam or phishing emails

  • Do not provide sensitive information via email as scam or phishing emails are usually disguised as a personal email from a friend.
  • Do not open emails or attachments from senders you do not recognize.
  • Be careful in clicking links sent through emails.
  • Make sure to double check URLs if they are correct.
  • When receiving an email from Citi®, the sender's email address should be Citibank Indonesia .

Text wisely and safely

  • SMiShing messages appear to be from a legitimate company and contains link that takes you to a spoof website or even asks to call a phone number.
  • Clicking links from these text messages can lead to other problems such as installing dangerous viruses on your phone.
  • Avoid selecting links in unsolicited text messages. Instead, go directly to www.citibank.co.id.
  • Do not respond to unknown numbers. If you miss a call on your mobile device or receive a text message from an unknown number, it's safer to ignore the call or delete the message.
  • Set up blocking features. Check with your network to see if they offer the option to block certain types of text messages.

Protect yourself against SIM Swap

What is SIM Swap?

SIM Swap is the process of replacing your existing mobile SIM with a new SIM to facilitate fraudster to get access to your financial account.


How does a fraudster do SIM Swap?

  • Fraudster collects victim's personal banking information.
  • Fraudster approaches victim's mobile operator with victim's fake identity proofs & obtains a duplicate SIM card.
  • Mobile operator deactivates the original SIM card post successful verification & issues a replacement SIM.
  • Fraudster generates the One Time Password (OTP) which comes on the new SIM & carries out account transactions without victim's knowledge.

  • Never disclose Internet banking password/ATM PIN/Telephone PIN to anyone.
  • Do not disclose your mobile number on social media platforms.
  • Register for both SMS as well as e-mail alerts to stay informed about transactions on your account
