Well, that was fast wasn't it? Before we could even get our hands really dirty with the T-Mobile G1 and Android, a security flaw has already been found. A group of security researchers have found that after visiting a malicious website, malicious code and software can be installed onto your G1 which will track your keystrokes. This is obviously not good news for anyone who uses Mobile Banking or enters their Credit Card number, among other things.
Google is a little peeved at the whole situation, wishing that the research group would have kept the flaw quiet until they come up with a fix. But the truth is, with phones becoming more and more like their PC counterparts, we all need to be aware of the power of smartphones and thus the risk.
