The renaming of the attachements .exe to .fix is just it... Please run this file but to avoid problems with the filtering systems we have named this fiel .fix please save it to your system as .exe Yet a matter of education. My Kids will know not to run files like that and so do the OLDER members of my family. I tell them if you get an email like that let me know and I will fix your computer. BUT NEVER EVER run anything that comes over the Internet even if it looks like it came from me. For members of my family that live to far away, I an telephone support. Content filtering and monitoring is an ugly beast some folks what there email scanned while others do not care some want the spam blocked and others do not care. The problem on a larger mail server cluster would be deciding who wants it scanned are blocked and who does not... -- lhe On Thu, 2005-12-29 at 09:25 -0500, Michael Holstein wrote:
i believe the fucking word "fuck" triggers some .gov filters in a noisy way :)This RegEx method of filtering (alas .. employed all too regularly) is exactly why we get emails for "C1ali$" or "V1agara" or "Steamy Pr0n". It's like trying to block attachments based on the extension, while ignoring the magic bits in the header. The next round of "social engineering" emails that say : "rename the attached .fix file to .exe so you can run it correctly" are just around the corner. /mike. _______________________________________________ Full-Disclosure - We believe in it.
