One of the things I discovered yesterday while looking at Krebs on Security was that Google Alphabet has a program to provide hosting and dDOS protection for journalists. Project Shield, as it’s called, is a free service for approved applicants that keeps up websites that might be taken down otherwise. Eligible organizations include those providing news, information on human rights and...
Cybersecurity has been on my mind lately. There is a lot of bad stuff going on, from giant dDOS attacks, to subscription bombing, to the ongoing low level harassment that some people have to deal with on a daily basis. I’ve written a lot about how I think marketers are going to have to step up and stop being a conduit for abuse. I do believe this. There are a lot of different issues to...

A lot of it has been overly excited and exaggerated, probably in an effort to generate clicks and ad revenue at the relevant websites. But we’re starting to see the security and network experts talk about the attack, it’s effects and what it tells us about future attacks. I posted an...

This is the biggest denial of service attack in history, with as much as 300 gigabits per second hitting Spamhaus servers and their upstream links. This traffic is so massive, that it’s actually affecting the Internet and web surfers in some parts of...
The CBL website is back on line. It’s possible that your local DNS resolver has old values for it cached. If so, and if you can’t flush your local DNS cache, and you really can’t wait until DNS has been updated then you may be able to put a temporary entry in your hosts file to point to cbl.abuseat.org. You can get the IP address you need to add by querying the nameserver at ns...
