Citibank customers are now being targeted in a phishing campaign by scammers impersonating the bank online.
According to Bitdefender, the cybersecurity firm's Antispam Lab recently observed thousands of phony email messages sent to the bank's customers with the aim of stealing their personal information and online credentials.
While these campaigns are primarily focused on the US with 81 percent of the fraudulent messages sent ending up in the inboxes of American Citibank customers, they have also reached the UK (7%), South Korea (4%) and a limited number even made it to Canada, Ireland, India and Germany based on Bitdefender's internal telemetry.
When it comes to the origin of these phishing campaigns, 40 percent of the fake emails appear to have been sent from the US while 13 percent originated from IP addresses in Mexico.
Instilling a sense of urgency
In order to trick Citibank customers into opening their emails, the cybercriminals behind the campaign use email subject lines that try to instill a sense of urgency including “Account Confirm Confirmation Required,” “Second Reminder: Your Account Is On Hold,” “Security Alert: Your Account Is On Hold,” “Urgent: Account Confirmation Required,” and “Urgent: Your Citi Account Is On Hold”.
Although some of the phishing emails used in the campaign utilize the official Citibank logo to appear more legitimate, the scammers behind it failed to put in the effort needed to spoof the sender's email address correctly or fix any of the punctuation errors in the email body.
Another tactic used to make these phishing emails to look like they're coming from Citibank itself is citing fake transactions or payments and even suspicious login attempts to trick potential victims into verifying their accounts. However, clicking on the verify button actually takes victims to a perfectly cloned version of the official Citibank landing page where they can log in using their user ID and password. If a Citibank customer goes this far though, the cybercriminals then harvest their credentials to use in future attacks.
Responding to fake email alerts from Citibank or any other financial institution can lead to serious consequences including identity theft and fraud. To avoid getting duped, users should carefully examine the body of such emails for typos as well as check the sender's email address and any embedded URLs before clicking on them.
