Welcome to the Security Center

Scammers are calling individuals posing as clinic or hospital officials claiming that a relative of the victim has fallen sick with the virus and request payments for medical treatment.

What you can do to protect yourself

• Stay Alert by practicing heightened awareness and being wary of people calling/emailing posing as medical facilities soliciting payment for medical treatment.
• Do not release financial or personal information without first confirming your loved ones are seeking medical treatment, or calling back directly to a hospital or physician's office to verify the need for payment information.

Citi has been made aware of various emails claiming to be from national or global health authorities, with the aim of tricking victims to provide personal credentials, payment details, or to open an attachment containing malware.

What you can do to protect yourself

• Validate the website is legitimate if you are being solicited to donate to a COVID–19 cause via e–mail. For example, Citi has seen reports of fraudulent websites that are trying to replicate the World Health Organization's COVID–19 Solidarity Response Fund (https://covid19responsefund.org/).  Ensure you are visiting the correct URL.
• Protect yourself from malware and phishing attacks by not opening attachments from unfamiliar sources, or providing website login credentials via e–mail.

Government Stimulus Package

The US Government passed a stimulus package that includes payments to eligible individuals and we expect to see an increase in fraudulent attempts to obtain your personal and financial information. Unfortunately, scammers are aware that money and payments are very enticing bait in phishing emails, text-based attacks and social engineering.

What can you do to protect yourself

• Be suspicious of emails or text messages that request you to take any action to receive your money
• Do not click links, open attachments, or provide any personal or financial information to anyone if you feel suspicious or cannot verify the source of communication
