A distributed denial-of-service (DDOS) attack has disrupted the ticketing systems of SJ, Sweden’s state-owned passenger train operator. Anonymous hackers say they have nothing to do with the attack.Local reports say that problems began on Wednesday when the SJ ticketing system was disrupted for around three hours. Today, the attack was resumed. At the time of writing, SJ’s website is inaccessible.
The DDOS attack on SJ is preventing travelers from booking or buying tickets online. The ticket machines are also out of order.
While SJ is trying to mitigate the attack, rumors have surfaced that Anonymous might be behind it. An Anonymous news website from Sweden has picked up the story, but the hacktivists haven’t actually claimed credit for the operation.
“There is no operation from #Anonymous against SJ in Sweden. We are not behind the DDoS attacks against SJ. Please don't spread false rumors,” reads a message posted on Twitter from several Anonymous Sweden accounts.
