The Spamhaus Distributed Denial of Service - How Big a Deal Was It?

If you haven't been reading the news of late, venerable anti-spam service Spamhaus has been the target of a sustained, record-setting Distributed Denial-of-Service (DDoS) attack over the past couple of weeks...

DNS Reflection/Amplification Attack: Proved

Last year there was a "threat" by anonymous group to black out Internet by using DNS Reflection/Amplification attack against the Internet DNS Root servers. I even wrote a little article about it: "End of the world/Internet". In the article I was questioning if this was even possible and what was needed as general interest and curiosity.

IPv6: SAVA, Ca va pas?

Sender Address Validation and Authentication (SAVA) is the silver bullet. It will send to Cyberia all dark forces that make us shiver when we make a purchase on the internet, pose a threat to our very identities and have made DDoS a feared acronym. Some of you will remember the heated debates when Calling Line Identification (CLID) was first introduced in telephony. Libertarians of all stripes called passionately to ban such an evil tool...

The Christmas Goat and IPv6 (Year 3)

As Christmas were getting closer, the third time of load balancing the streaming pictures of the famous Christmas goat in the city of Gävle, Sweden, was on the agenda.

2012 Global Phishing Trends: Uptime Down, Numbers Up

Despite security advances over the past year, including the increased deployment of DNSSEC, pirates continue to wreak havoc on the Internet. But before you decide that Internet security innovations are futile, consider this: online criminals are just like burglars in the physical world; they don't take new ways of blocking their best efforts lying down. They come up with new and, in some cases, stronger plans of attack.
