Caller ID Spoofing Will Soon Be Illegal

Caller ID spoofing is rather easy to do for anyone who is willing to make the effort and apps to make it even easier. It’s akin to forging the “From:” header in an email. Both of these standards were developed in a time and environment where malicious use wasn’t a concern. Today obviously that’s hardly […]

Google Mail Fail

Found an interesting header when doing some tests with mail filtering: Received: from qb-out-1314.google.com ([172.21.30.5]) by mx.google.com with ESMTP id k29si2692710qba.7.2008.09.06.14.48.05; Sat, 06 Sep 2008 14:48:06 -0700 (PDT) Received-SPF: softfail (google.com: domain of transitioning user@example.com does not designate 172.21.30.5 as permitted sender) client-ip=172.21.30.5; Authentication-Results: mx.google.com; spf=softfail (google.com: domain of transitioning user@example.com does not designate 172.21.30.5 […]

Email Image Protection

Many people think that making an image out of an email is a good way to protect it from being harvested by spam bots. It’s now possible to convert it from an image to email link via a Firefox extension. Guess what, an email harvester can do this just as well. What’s a better solution […]

Google Used For Spam

This happened a few weeks ago. I kept it quiet and reported it. Hasn’t happened again, and I haven’t heard anything, so I presume it’s fixed. It appears spammers have learned to hijack Google Alerts for spamming purposes. By setting up an alert with a spam text, the email is sent through Google’s mail servers. […]

Spam Havens Follow Up

Ok, so 1 business day after I found a few spammed sites: Apple has removed the page, no comment. Riverside, CA acknowledged and said they are in the process of resolving. I’ll keep an eye out to see how long it takes. AOL has removed the page, no comment. So there you have it, 3 […]

Spam Havens?

I’ve recently seen an increase in spam around here slipping through the filter. In an attempt to keep this site clean, I keep a close eye on comments. Typically checking several times a day, and removing url’s that are pure spam, or just inappropriate. But over the past several days things have been getting stranger. […]

Comment Liability

Interesting to see that after a Blogger was sued over comments posted a blog, there is a federal court ruling that pretty much says that’s not allowed. Something tells me, if a kid clicks on a blog spam link that goes to a porn site, you can still get 40 years in prison. Spam is […]

The Crushing Junk Folder

Since 9/19/2006 when I last emptied my Junk folder, my personal email address has 1.65GB (yes, gigabytes) of Spam/Viruses in it. That is in my opinion a sign of a serious problem. Oh yea, a few weeks ago, we began auto-rejecting email from certain blacklisted servers, which drastically cut down on spam. And still it […]

Bayesian Spam Filter Poisoning With RSS

Overview Bayesian Filtering is a great method for fighting spam. Unlike rule based filtering which spammers can easily adapt to with simple modifications, Bayesian adapts with the spammers changes, making it much more difficult for them to defeat the filtering. As a result it’s used in server side mail filtering as well as client side […]

Coming Soon: Bluejacking

If you have bluetooth on your phone, there’s yet another reason to turn it off when you don’t use it. Besides saving battery life (which is always a good thing), and just general security you’ll be seeing more and more spam as time goes on if you keep it on. It’s already a problem in […]
