I worked at a very large company that had a email virus move quickly through the ranks...<p>The subject of the email was "Please see attached documens" in which a PDF was attached that upon opening would hijack your email account and send the same. Over the first day, I had about 100 emails from coworkers in my inbox. After our "IT Security" team sent out an email claiming they stopped the threat, the following day more emails came from coworkers that was a slight variant but had more typos.<p>I still wonder what sort of breach occurred and whether our internal teams performed a true investigation... obviously a foreign intrusion and they managed to at least gain control of quite a few internal machines.<p>I still get a laugh out of using the same subject in an occasional email to coworkers...
