Cyberattack on N.S. university network due to cryptocoin mining: St. F.X.
A Nova Scotia university says it was forced to shut down its network for four days last week because of a cyberattack involving so-called cryptocoin mining.
St. Francis Xavier University says in a statement that the software tried to use the school's "collective computing power in order to create or discover bitcoin for monetary gain."
But, it says there was no evidence that personal information in the network was breached.
In cryptocurrency mining, digital currency transactions are recorded, verified and stored in a public ledger called the blockchain.
So-called miners use powerful computers to navigate cryptographic problems to select transaction blocks, with the transaction fees associated with using cryptocurrencies being awarded to the miners.
The university pulled its website offline Thursday as the school began investigating the issue, disrupting access to email, Wi-Fi, debit transactions, the school's online course system and drives on the St. F.X. network.
