In another "false-claims" spam story this week, Opera has published an advisory that is warning people about a wave of fake e-mail that disguises itself as coming from Opera. The company mentioned today that the emails use fake signatures , including one that would make it appear as if the email is being sent from an Opera mail client.

Of course they say the spam has nothing to do with them, and point out some obvious flaws people can use to detect it. Common sense dictates spam is often easy to identify anyway, but Opera suggested anyone using the Opera mail client change the default signature. Though this isn't surprising, it is still indicative of the "next-generation" spam which attempts to custom-tailor to specific people or groups.
