InfoWorld reports that Trend Micro said that it had spotted the first attack taking advantage on an IE flaw that was patched by Microsoft last week

Microsoft warned last week that it would be easy for cybercriminals to build new attacks using bugs it patched in the Internet Explorer browser; now that prediction has come true. On Tuesday, security vendor Trend Micro said that it had spotted the first attack taking advantage of one of two flaws patched a week ago. Microsoft has said that either of these vulnerabilities would be easy to exploit in online attacks.
