Dyn DNS was at the receiving end of a massive denial of service attack last week, and recently FlashPoint issued a preliminary report about what happened.

The business intelligence firm concluded that the attack was most likely perpetrated by amateur hackers, rather than the widely held belief that it was launched by some state-sponsored hacker group.

The attack, reported on Oct. 21, crippled Dyn DNS' domain name which in turn affected access to a range of websites in some parts of the United States.

According to Tech Crunch, among the affected websites were Twitter, PayPal, Amazon, GitHub, Reddit, Netflix, RuneScape and Spotify.

Following the DDoS attack, several speculations claiming that it was committed by a group of Russian hackers started to surface on tech forums.

A handful of groups also claimed responsibility for the attack, including a group calling themselves the New World Hackers.

In a bizarre act of admission, WikiLeaks even joined into the blame game suggesting that some of its supporters might be involved in the attack.

While there are several organizations claiming responsibility for the Dyn DNS attack, FlashPoint is siding with its theory that it was done by script kiddies, hackers who use scripts developed by other people to launch disruption of services to networks and websites.

FlashPoint came up with this explanation after they found out that the same type of attack was used to target a well-known video game company.

In its report, FlashPoint analysts wrote, "While there does not appear to have been any disruption of service, the targeting of a video game company is less indicative of hacktivists, state-actors, or social justice communities, and aligns more with the hackers that frequent online hacking forums."
