The servers that are behind the largest denial of attack on Minecraft servers, the most recent round of downtime, were not part of the original attack, but have been compromised, according to researchers at Johns Hopkins University.
The researchers also say that they did not find evidence of a previous attack on a server using a different server, and that they found no evidence that the servers were infected with ransomware.
“We have not seen evidence that this attack was part of an ongoing botnet operation,” the researchers wrote.
“We do not believe that there is any evidence that these servers are vulnerable to other botnets.”
The researchers say that their findings could help explain the massive spike in activity on the server servers on the same day that the Mojang servers were offline.
