Trend Micro has identified a new Flash ZeroDay exploit.
A ZeroDay Exploit is when a new bug is found in an application like Adobe Flash that is discovered, but no protective or ameliorative patch is available yet. This means “YOU ARE AT HIGH RISK OF BEING COMPROMISED”. This one is a real problem, because the attack vector relies on infected ads on otherwise trusted sites.
What can you do?
Install the latest patch whenever Adobe releases it. Limit your web browsing, and don’t think you are impervious to exploit.
