Commentary

  • Overall for 2011, 1 in 298.9 emails was identified and blocked as a phishing attack, compared with 1 in 442.1 in 2010; an increase of 0.11 percentage points.
  • 85.2% of phishing attacks in 2011 related to spoofed financial organizations, compared with 56% in 2010.
  • Phishing URLs spoofing banks attempt to steal a wide variety of information that can be used for identity theft and fraud. Attackers seek information such as names, government-issued identification numbers, bank account information, and credit card numbers. Cybercriminals are more focused on stealing financial information that can make them large amounts of money quickly versus goods that require a larger time investment, such as scams.
  • Phishing schemes continued to use major events to entice recipients: Many email-based fraud attempts referred to major events in 2011. Examples included the Japanese earthquake, where the criminals would attempt to exploit people’s sympathies for the victims of the disaster. Many charities sought donations to provide support and cyber criminals exploited this by sending 419-scam emails in which they spoofed legitimate charities with fraudulent websites.
  • 36.2% of phishing attacks were conducted through the use of phishing toolkits.
