I can see how this might alarm someone who is not computer savvy but uses a webmail service for e-mail. It made me think for about three seconds. But it’s so obviously a hoax. While I didn’t click the link in the message (and have removed it so no one reading this is tempted), I can only assume that clicking it will do one of two things:
- Take you to a Web page where you’re prompted for private information that the scammers can use to access your accounts somewhere.
- Install some kind of software on your computer to gather information from it (such as keystrokes) or make it part of a botnet.
I’m not dumb enough to enter information into a Web page linked to in an e-mail message from someone I don’t know, but I know plenty of folks who are. And, as far as I know, Macs are immune to the types of viruses and other software that can be installed by linking to an infected site. (Someone please use the comments to correct me if I’m wrong on this.) But most folks still do use PCs without proper protection against this sort of thing, so they’re likely to be compromised if the goal is to get software on your computer.
Please spread the word about this new phishing scheme. It’s likely to fool your mom or granddad or Aunt Tillie, even if it doesn’t fool you.
At first I thought it might be the document itself. It’s 40 pages of text that utilizes about 20 styles and fields for automatically numbering figures and illustrations. The document was originally created about 10 years ago and has been revised and saved periodically for every edition of this book. It pops from my Mac to an editor’s PC and back at least five times during each revision process. I thought it might have some internal problems. So I used the Save As command to create a new version of the document. The new file was about 5% smaller in size, but had the same symptoms as the original.

Guess what? As you can see in this screen shot, it was there.
