The best advice to average users is to delete all unsolicted email
attackments. There are various ways of hiding actual file extensions.
Some malware comes as:
purtygurl.jpg .exe
for one example where spaces are used to hide the .exe extension.
Another trick is to use the scrap file extension .SHS which Windows
hides:
purtygurl.jpg.shs
appears in Windows as:
purtygurl.jpg
and the actual scrap file _ is_ executeable. The same can be done
with .SHB files.
Perhaps the most powerful piece of social engineering of late has
been the malware with a message seeming to come from your ISP
containing a attackment which you are encouraged to open. The
variations on this theme are amazingly real looking, and it's no
wonder average users will unzip and open and Run the attackment.
