The UPS emails I mentioned last week have now become 'Custom Service' emails. Again do not open as they contain a trojan zip file.

Beware of emails coming through with the subject line 'UPS Tracking Number 56429599222' or similar. They are junk emails with zip files containing trojan viruses. The latest version of Avast identifies it as a trojan.

Today I've seen a couple of instances virus turning up as a spam mail. It's disguised as 'Greeting Card.exe', 'Flash Postcard.exe' or similar and most importantly is not being detected by the latest version of AVG. I have emailed the executable off to the vendors to get it added.

I've been seeing a lot of obfuscated spam over the last week or so. It's led me to write and test my first spamassassin rules:

If I host your email, you're seeing a lot of spam at the moment. I'm aware of it and am in the process of re-architecting things to beef up the spam processing and hopefully make the problem go away once and for all. I'm waiting on hardware delivery at the moment. Should have all the kit by the start of next week.

Myself and, independently, a couple of my friends received emails off other friends telling us how to get a free £60 voucher from Sainsbury's. All you have to do is send the email on to 10 of your friends, cc'ing an email address at customerservices dot com.

Checking the customerservices.com registration details, it's someone in Indiana. There's no link to Sainsbury's. The customerservices dot com website is a junk portal page.

What I suspect is happening is that someone's started off a viral email that is harvesting real email accounts via the CC in the email.
