Trojan targeting Password Manager

A password manager holds several passwords which can be accessed using one master key. Using such a program relieves the users from having to remember many passwords. On the other hand, these passwords are accessible using a single master key. A trojan named Citadel has been found to specifically target Password Managers such as Password Safe and KeePass. Research by IBM found that on average 1 in 500 machines is infected with this trojan.  The Citaldel Trojan is based on the open source Zeus Trojan.  Should you be worried?

The Citadel trojan has these capabilities:

• Modify web browser processes and monitor access to websites of interest.
• Steal data entered into HTML forms, such as online banking account credentials.
• Modify the HTML of targeted websites within the victim’s web browser.
• Redirect URLs to ones controlled by the malicious actor.
• Upload the HTML code of a targeted URL.
• Steal HTTP cookies and Flash cookies.
• Instrument additional processes to attempt to steal additional account credentials (e.g., FTP and
  POP3) from network communications.
• Download and execute additional programs.
• Provide a built-in Virtual Network Console (VNC) server with the ability to connect out to a
  remote server.

Summarized:  it can directly access the machine, execute packet sniffing and steal your credentials. The Citadel trojan targets Windows machines and users from other platforms might be safe from infection.
