It appears the Citibsec website located at citibsec.com is a fake and scam Citibank website. The newly created website, which was registered only a day ago, seems to be used by scammers in text messages to lure potential victims to the fake Citibank website. Therefore, recipients of text messages with a link to citibsec.com are asked not to follow the instructions in them until the authenticity of the website can be determined. In the meantime, you may go directly to www.citi.com and sign in to your account for information.
