Botnets: Does Size Matter?

Mon, Mar 18, 2013 by Andrew Conway

Every so often the command and control servers for a botnet get taken down, and we are told breathlessly by the more extravagant security experts that this botnet was responsible for a quarter (or a half or a third) or all the world’s spam, and that we can expect to see a big reduction in [...]

Today the Federal Trade Commission (FTC) announced that they have charged 29 defendants with collectively sending 180 million unwanted text messages.

Fri, Feb 22, 2013 by Chris Barton

It’s great to see Twitter taking the lead on the URL shortener security.

Lawerence Gostin, the Georgetown University law professor and World [...]

Does fining spammers help?

Mon, Feb 11, 2013 by Andrew Conway

One of the most common sorts of SMS spam in the UK relates to Payment Protection Insurance or PPI.

Wed, Jan 23, 2013 by Andrew Conway

Mon, Jan 14, 2013 by Andrew Conway

Early last year I wrote about the increasing amount of spam that was using hacked web servers to obfuscate the spammer’s call to action. Back then the volume was creeping up to 1% of all spam. Since we’ve been seeing even more of it lately, I decided to take a look at the figures and [...]

Getting Rid of SpamSoldier

Fri, Dec 21, 2012 by Andrew Conway

A couple of days ago all the domains used by the Android Spambot went offline and have stayed down. This includes the Command and Control servers, so the army of zombie droids are now headless. However, if you did get tricked into installing this malware it will still be blocking some of your incoming texts, [...]
