AurumCoin team has reported the 51% attack, which resulted in a loss of 15,752.26 (some $571,000) from the Cryptopia platform.
According to the news report, the project team stated that they were not responsible for the accident, citing an open code of the token. As a result, they throw the exchange under a bus.
The company posted the corresponding notice on its website, saying:
"Aurum coin (AU) network was hacked (51% attack), a total of 15,752.26 AU is missing from Cryptopia’s wallet (cryptopia exchange). Aurum coin network is not the responsibility of anyone, same as Bitcoin network, it is an open source distributed cryptocurrency. What’s worse is that cryptopia exchange does not admit it. This is not the way to solve this problem."
In fact, they do not blame Cryptopia directly, so state the fact of the loss. The probable scenario of the accident is following – the hacker sent the funds to Cryptopia account, exchanged into other crypto and then cancelled transaction using on-hand capacities.
For reference, AU token is said to the first coin backed by gold (1 troy oz gold 999) kept in secret storages dotted around the world, as the company founder commented.
