"Pharming"

Guidance on How Financial Institutions Can Protect Against Pharming Attacks

July 18, 2005
Summary: The 多宝游戏下载 is issuing the attached guidance to financial institutions describing the practice of "pharming," how it occurs, and potential preventive approaches. Financial institutions offering Internet banking should assess potential threats posed by pharming attacks and protect Internet domain names, which 鈥 if compromised 鈥 can heighten risks to the institutions. 

Highlights: 

  • "Pharming" is the process of redirecting Internet domain name requests to false Web sites to collect personal information. Information collected from these sites may be used to commit fraud and identity theft.
  • The attached guidance explains how pharming occurs and recommends strategies for protecting financial institution Internet domain names from a successful pharming attack.
  • The effectiveness of an insured institution's Internet domain name protection program should be addressed in periodic risk assessments and status reports presented to the institution's board of directors.
