E-mail

This is a particularly dangerous phish case. First off, the e-mail you get is definitely made to look as unsuspicious as possible:

  • The sender looks legitimate (service@usbank.com);
  • The e-mail carries a US Bank logo;
  • It does not demand from you personal information in an e-mail - it offers you to log in;
  • The link listed is the legitimate US Bank personal banking login URL (it is actually spoofed, but you can't see that when you open the message).
  • It does not treat you aggresively - there is no mentioning of an "immediate" need to comply.

The only thing that could raise your suspicion is the strange policy itself.

URL in Internet Explorer: http://www.usbank.com

The site uses a flaw in MS Internet explorer to make the page look as it is on usbank.com. The phisher has copied all the resources (fonts, pictures) and styles of the legitimate page, and used them to create a very convincing and a very dangerous deception. Very little could tell you that this is not the official page:

  • Note that the bottom of the page says "Connection secured", while you have no indication of visiting a secure site from your browser. Also, the URL in the address bar also does not start with "https", but with "http";
  • The URL says jus "www.usbank.com" - which is the domain name, but not a real URL (there is no filename or pointer at the end of it)

Once again - the policy itself is suspicious.

 

 
After getting your informarion, the phish site redirectis you to the legitimate US Bank login page:
