The Friday cyberattack on an Internet company that disrupted major websites including Twitter, PayPal, and Amazon was probably carried out by low-level hackers referred to as “script kiddies,” according to new research by cybersecurity firm Flashpoint.

“Flashpoint discovered that the infrastructure used in the attack also targeted a well-known video game company,” the company noted. “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.”
