GOEL and GAURAV ARYA* Professor of Mathematics, Amity University, NOIDA, * Dept of Mathematics CCS University, Meerut (UP) Abstract: Hacking is so simple! Not only the operating system‟s loop holes offers opportunities to hackers but also the applications like Skype and Google Chrome developed for the operating systems are quite attractive to hackers. In this paper I present the various ways in which the passwords like user account‟s passwords stored by the operating system or the passwords required by different applications are stored on the system and can be hacked by intended hackers. This paper presents in depth research of the password storage mechanisms implemented in various versions of Windows and various application software and can be exploited by hackers. Keywords: Hacking, Windows, SAM, Skype Introduction Passwords can be login passwords for operating systems like Windows or login password for any application like yahoo messengers etc or login password for any web site like email login passwords. We will study the password storage mechanisms and analysis of their strengths for Microsoft Windows operating system and the applications developed for it. Microsoft Windows is the name given to the family of operating systems developed by the the US based company Microsoft. Microsoft first introduced an operating environment named Windows in November 20, 1985 [1] In thi s paper, we will di scu ss Wind ows 9 8 /ME, Wi nd o ws NT /XP and Wind ows 7 . We will also study how actually the passwords of various applications like Web Browsers store the passwords on local drives. Password Storage Mechanism for Windows operating system Windows-based computers utilize two methods for the hashing of user passwords, both having drastically different security implications. These are LAN .
