The jpg is a compression from not just an ext. when you execute the JPG it decompresses.. Do not know sense I do not hack but know that it is the only way friend could have gotten a troj since the only thing he used one of his computers was for irc. Mind you he asked me to make sure people cant send anything but pics.. Yes he was a little bit of a perv. So I blocked everything cept *.bmp, *.gif, *.jpg, *.TIF everything else was blocked and no prompt. Someone told him he had a torj. So I did a little looking.. Looked at his log files.. Only seen jpg and a couple bmp's and well found the virii cleared it out. Then opened each file until I found the offending one. Again don’t know how it worked and it was a .jpg not a .jpg.src file -----Original Message----- From: Matthew Hanson [mailto:[EMAIL PROTECTED]] Sent: Friday, February 08, 2002 3:05 AM To: Libretto Subject: Re: [LIB] List problem?

BUT! That's not in truth a real JPG file, only one with a tricky extension. Phillip says that virus code can be written into a JPG file. For the life of me I can't figure out how it would spread any virus. It'd need a separate execuatable file to activate the virus code in the JGP, wouldn't it? And the're nothing to my knowledge (admittedly limited knowledge) that tries to execuate any kind of code in graphics files.
