Today we added detection for a simple worm W32/SillyFDC-Y which reminder me of 'old school' malware. The worm periodically copies itself to removable media such as USB keys. It tries to create a hidden autorun file to launch itself whenever the device is connected to an uninfected machine.
Although the technology has changed, it is strangely reminiscent of 'old school' viruses that spread via floppy disk when I started in the security industry all those years ago. Does anyone even remember floppy disks?
