The US Computer Emergency Readiness Team (US-CERT) have warned computer users across the world to be wary of "potential email scams, fake anti-virus and phishing attacks regarding the Japan earthquake and the tsunami disasters." They also said in their statement, “Email scams may contain links or attachments which may direct users to phishing or malware-laden websites."
They also added in their official statement, “Fake anti-virus attacks may come in the form of pop-ups which flash security warnings and ask the user for credit card information. Phishing emails and websites requesting donations for bogus charitable organizations commonly appear after these types of natural disasters."
Phishing is a major threat to computer users across the world where user names, passwords and other personal information are under risk mostly through email or instant messages.
