What is in Kelvin's Head?

Under attack

19/04/2013
Some people will have noticed that some of the websites that I look after have been under attack this week. Naughty people are trying to gain control of a load of web servers and mine has been one of the many targeted.

What has been happening is that someone has had the great idea of trying to crack as many WordPress sites using a brute force attack. That means setting computers up to try to log in to a site automatically using a computer program to try as many different password combinations as possible. The same technique was a feature in the film War Games of some years ago – the computer in question being the one which controlled US Missiles. My computers have slightly less power.

People do this to gain control of servers so they can do naughty things like use them to send out lots of spam all at once. (Ever wondered where it came from?)

The consequence for my readers this week is that at some times, my websites have been showing up in various security systems (Norton, AVG) as infected and this meant that people couldn’t get access to the sites whilst this protection was in use.

I think I’ve nipped it all in the bud.

For anyone experiencing the same trouble, here’s some of what you can do to help.
- Change the password combination on your server.
- Change the password combination on your blog/WordPress installation.
- Install a plugin like Anti-Malware and use it to scan and remove malicious code that has been injected into your site.
- Install a plugin like Better WP Security and word through what it recommends. At the very least, make sure you don’t have your administrator account in the name “admin” and use the plugin to lock down your login screen – you can set it to ban an incoming IP address after 10 failed attempts to log in, for example.
- Don’t panic.
For anyone who isn’t having the same trouble, consider doing the security things anyway.

Thanks for linking +David’s post. I’d read it, and the first few comments, but missed that later discussion. It represents a new level of blog dialogue in the SEC, I think.

Thanks for the episcopal summary – I take back my previous criticisms about the bishops. They are being rather splendidly thoughtful at the moment. As was Archbish Sentamu on Radio 4’s question time 🙂

Kelvin – thanks for your linking and attention-drawing activities. It’s hard not to be aware that there is a common thread linking all of those ‘over the parapet’ contributions – which is that the tone of recent contributions from our Catholic colleagues has been unfortunate. But now that we seem to have some momentum, I hope we can move on to be a bit more successful at shaping an agenda rather than simply responding to others.

What’s the clergy equivalent of a mitre over the parapet?

A biretta over the altar?

I can see snow on Cruachan. Birettas may be worn.

(See number 79 of my 100 things if you’ve no idea what Stewart is alluding to).
