The code used in the Oulu city cryptojacking was to generate a cryptocurrency called Monero.

The malware was used through victims’ computers when they visited the city’s website, but was only active when the site was viewed, according to Nykänen.

“The malware was active as long as the site was viewed, but did not install anything on users’ computers,” he said, adding that the offending script had been removed and the city’s system was fully operational on Monday. .

The city became aware of the incident after Yle’s IT security team noticed suspicious traffic coming from the city-run site over the May Day weekend.

The origin and cause of the hack were still under investigation on Monday, according to Nykänen, who added that it may have been a security breach, but that was still unclear. .

Cryptojacking has been used for a few years now. In some cases, operators of shady websites install the mining scripts themselves, but legitimate websites can also be hacked for such purposes, according to Yle’s IT security manager, Kim Johanson.
