While the last beta version of Windows 7 (RC1000) was released couple of days ago, it can also be found on P2P networks. Two scientists have successfully created a 3 KB piece of code able to bypass all security procedures and to access to data stored in different user accounts installed on the infected computer. According to both scientists, Microsoft will not be able to fix this back door otherwise than rewriting large part of the code.
As one could expect it, this report is heavily commented on the IT-dedicated websites. It is also a good moment to remind all users that the best protection again such attack is not software-based, but hardware. If you do not let free access of your computer to any foreigner, then you should not fear such problems. What is currently reported for Windows 7 can also be applied to Mac OS X, and someone getting hands on your computer can in couple of minutes apply a similar strategy to get information or install spy applications (except if FileVault is activated). So once you know that a direct access to the computer is required for such exploit, then you can easily avoid it by keeping your computer under control, or locked/switch off when not in used.
