Trend Micro Interscan Viruswall Multiple Program Buffer Overflow Vulnerability | 2001-04-15 22:37:05

Invisible file extensions on Windows | 2001-03-27 21:19:58
A little while ago, I was having a conversation with some of my colleagues about computer viruses. The "Life Stages" virus was mentionned during the conversation. This virus disguises itself via a file with extension .SHS, while pretending to be a .TXT file. This was possible because the .SHS extension is hidden by Windows, even if it is configured to display all files, all extensions (even for known file types). .SHS stands for "shell scrap", which means that it is possible to use these files to execute commands on a computer (which is what the virus did). Following this discussion, I thought to myself "I wonder if there are any other file extensions with these attributes that could potentially be used in a virus design?". This paper presents the results of this research.
