The company my sister works for has had their site hacked by Knex & Gorex. I have worked out that they are from Turkey. They do not appear to be very malicious, more just highlighting security vulnerabilities. Anyone know anything about them?

I dont know anything about them but what good would it do you to know?
If you search the underground websites or newgroups you could get more details but it wouldnt help in anyway.

Most things like this are done with a kiddy script which just searches for vulnerable  web sites

Just curious.
