Alert to Email Scam

Email is one of the main communication channels for both personal and commercial dealings. Nowadays, fraudsters hack into email accounts and cheat victims by all possible means to make remittances to them. Some victims have suffered significant losses from such email scams. You should stay alert to suspicious emails and raise your awareness in preventing this kind of scam, such as taking the initiative to confirm the true identities of recipients by telephone, facsimile or other means before effecting remittances so as to prevent such kind of scam. Please read "Security measures to be taken by you" and preventive measures to mitigate the risk of hacking.

Please also note the following common characteristics of phishing emails.

  • Emails from unknown senders, sometimes the email address containing random strings and characters
  • Senders' name and email address may be exactly the same as the genuine information of the Bank
  • The email usually looks like an important notification from the Bank (e.g. "Notification for a huge amount of fund transfer in the customer's account", "Request the customer to activate security authentication function" or "Suspension of a specific banking service" etc.). The recipient will be asked to click the hyperlink or open an attachment in the email
  • Address shown by hovering your mouse over the hyperlinks different from what is displayed
  • Content with spelling mistakes and poor grammar
  • Attachments with suspicious file extension (e.g. *.exe, *.vbs, *.bin, *.com, *.pif or *.bat or others)
  • Requests for disclosing sensitive information (e.g. personal information or login credentials)
