yahoo! email changed content to stymie h4x0rz
Yahoo! has announced that its free email system changes the contents of messages in a previously undisclosed effort to limit the spread of viruses. Unfortunately, in an, um, undocumented feature (bug!) the system apparently replaces strings--groups of characters--not necessarily complete words. For example, although Yahoo! declined to list the specific strings its system alters, one change that's been identified is swapping "review" for "eval." Since the program just looks for the string e-v-a-l, not the complete word, an email sent with the word "medieval" would arrive reading "medireview."
