Facts:
1 - one of the two incidences reported (#EGI2020512) targeted academic data centers "for unknown purposes" (https://csirt.egi.eu/academic-data-centers-abused-for-crypto...) and not necessarily crypto currency mining.
2 - IP addresses associated with that second attack were all assigned to a Chinese University (Shanghai Jiaotong University), CSTNET and one Polish host known to be compromised by someone from China.
