Credential Stealing Malware in PDF Attachments

On Wednesday we talked about a phishing exploit that used malware to provide remote access and steal the personal information of the victims.  Today we continue the story with a similar exploit, called “Fareit” to “ferret out” the user credentials and other personal information the victims.

This exploit uses a phishing email to send the target either a PDF attachment or a Word attachment.  The PDF variant uses Windows Powershell to install.  The Word document uses embedded macros to do the job.  It is installed in a way that will avoid detection by most anti-malware products.

This exploit explores the computer, looking for:

  • email account credentials
  • domain name credentials
  • banking credentials
  • web-browser auth cookies
  • FTP server credentials
  • BitCoin credentials

This information is used to extend the exploit, or may be gathered into a package and sold on the Dark Web.  Learn how to spot a phish, and stay vigilant.  When in doubt, do not click.  And use VirusTotal to check out the attachment.
