It appears the Android software has a serious flaw, according to a group of security researchers. The word is Charles A. Miller, one of the researchers told Google of this flaw and said he was publicising it now due to his belief that mobile phone users are not aware that smartphones face the same threats as personal computers with internet access.
Apparently this flaw could well be exploited by an attacker which may trick the Google Android T-Mobile G1 user into visiting a booby trapped website, says former National Security Agency computer security specialist Miller.
Google, apparently acknowledged the problem, but stated the security features on the G1 would limit any extent of damage done by a potential intruder.
