Nice hearing from you again, DarkPen. We've missed you. I must say, my reaction to the CNN article at first was exactly the same as yours; this is a DATA file, it does not carry executable code. The general thread at slashdot felt that it was all a marketing ploy by McAfee. However, several posters did raise viable scenarios: a) If there is a known defect in some browser/image viewer software, a jpeg could be exploited to trigger that defect, thereby perhaps opening a security hole. This sounds like very much a contrived scenario, but I guess it has happened in the past with defects like "buffer overflows." b) Other postings seemed to speculate on compression algorithms (future?) that are more procedural; carrying code instructions for recreating or displaying an image. I do not think these are really something to worry about today. Thankyou very much, BTW, for putting the blame on CNN for spreading this rumor.
