A digital firefight is bogging down the entire Internet thanks to botnets – masses of hijacked computers – employed by spammers as digital cannons to attack an anti-spam group.
So-called “distributed denial of service” or DDoS attacks are nothing new and barely raise an eyebrow among cyberwarfare experts. This is different. In this case it’s the size of the attack that’s garnering the attention – about three times larger than the largest previously recorded DDoS attack.
The target is Spamhaus, a European group that tracks spammers on the Internet. Much to the annoyance of spammers, Spamhaus maintains a blacklist of bad actors that it distributes to spam-blocking services worldwide. Blacklisted sites have hit back before – but never this hard.
Arbor Networks, a cybersecurity company monitoring DDoS attacks, says Wednesday’s attack appears to be the biggest on record – about 300 billion bits (300 gigabits) per second. That’s big enough to have an impact on data intensive services like Netflix, which was among services reportedly slowed by the attack.
