Weird "Ghost Spam" Testing Addresses

A wave of strange emails with strings of numbers as their only message are most likely a spammer's or hacker's test of his mailing list, several security companies concluded Thursday, and may presage a junk mail campaign or a malware attack.

The messages, which Panda Software characterized as "ghost mail," are unusual in that the send and from fields are the recipient's own address, that the subject heading is a number -- 455, 557, 56757, 586876, or 1545453 -- and the message body is a mix of HTML and apparently random numbers.
