Police appeal that if you receive any suspicious emails, you should confirm the identity of the senders by means of telephone before remittance so as to prevent from being deceived.

Man-In-The-Browser Attack

Please be highly aware of a recent online threat known as a Man-In-The-Browser (MITB) attack, where an attacker takes control over a customer's connection and transmits counterfeit screens to the customer in attempt to capture and manipulate customer data.

  • A frequent MITB attack scenario involves the attacker taking control over a customer's login session. The attacker transmits screens similar to the online banking screens requesting the customer to wait while their details are being verified. During this, the attacker would initiate a request for adding payee or updating personal information while the customer's account is being compromised. An SMS containing a One-Time Password (OTP) is sent to the customer's mobile phone as part of the process. More counterfeit screens are transmitted to the customer to prompt the customer to key in the OTP in order for the attacker to proceed with payee addition and/or personal information update.
  • Please do not proceed if you notice an unusual screen or message during your online banking login session.
  • Do not act on an SMS containing an OTP that you have not requested for, review your existing payee list for any unauthorized additions.
