Travelers who fly from New York to Las Vegas on Wednesday, October 16th, may fall victim to the most recent malicious spam shower on the Internet where criminals hunt credentials of fresh FTP accounts.
The fake message concisely informs travelers they have been upgraded and are invited to check the flight information attached. “You’ve been upgraded from New York, NY to Las Vegas, NV (LAS) on Wed., Oct. 16, 2013. Your new seat is 9D. Attachment is a recap of your flight information.” reads the message.
By accessing the attachment, people get their systems infected with a Trojan (identified by Bitdefender as Trojan.Downloader.JQCM ) that downloads another malicious piece of code (Trojan.GenericKD.1328431) to steal login credentials and passwords. Crooks appear utterly interested in new FTP accounts because the code comprises a huge list of FTP clients, including FAR, CuteFTP, FlashFXP, Bullet Proof FTP, SmartFTP, TurboFTP, SecureFX, LeechFTP, FTPGetter, ALFTP, FTP++, UltraFXP, FTPVoyager, WinFTP, DeluxeFTP, Staff-FTP, FreshFTP, BlazeFTP, GoFTP, 3D-FTP, EasyFTP, FTPNow, FTPShell, FTP Navigator, FTP Commander, FFFTP, COREFTP, ClassicFTP, LeapFTP, Total Commander, FileZilla, Robo-FTP. Attackers may want credentials to FTP accounts to host on them malicious code to be used in future attacks.
Browser-related credentials for Internet Explorer, Mozilla Firefox and Google Chrome and e-mail login data are other key points of interests. The Trojan takes screenshots and monitors e-mail clients, including Outlook, The Bat, Windows Live Mail, IncrediMail, or Thunderbird.
The initial downloader Trojan uses software restriction policy to avoid the locally installed AV solutions. Once it downloads and registers the payload, it wipes any trace of itself.
Although the message targets United Airlines customers, chances are other people traveling next week will be tempted to open the attachment and check the flight information.
Never open e-mail attachments delivered by messages you haven’t requested. Double-check the sender’s address and, if you don’t recognize it, delete it at once.
If you receive a message from a flight company and you are not sure it’s legit, call the company or pay them a visit to check the validity of their claim.
Use an antivirus and keep all your software up to date.
