Unknown hackers have tried to launch a second 51% assault on Vertcoin (VTC) however ended up paying for the privilege out of their very own pockets.
As Vertcoin’s lead maintainer James Lovejoy revealed in a report on the assault on Dec. 2, a malicious entity focused cryptocurrency change Bittrex with the intention to manipulate the Vertcoin blockchain.
Hackers paid not less than $440 to assault VTC
This time, nonetheless, it seems the exploit was a lot much less profitable.
“Primarily based in the marketplace costs in the course of the assault’s preparation and the issue of the blocks the attacker produced, we estimate the attacker spent between 0.5-1 BTC to carry out the assault,” Lovejoy defined.
In consequence, the hackers seem to have come out with a internet lack of between 0.06 BTC ($440) and 0.56 BTC ($4,100):
“The overall worth of the block rewards the assault obtained is 13825 VTC (~0.44 BTC). Given the assault was seemingly not worthwhile to carry out based mostly solely on block rewards, the motivation for the assault is just not sure.”
Combating for scraps
Bittrex is VTC’s most important buying and selling venue. After noticing suspicious exercise, Lovejoy requested the change halt VTC pairs, which appeared to restrict the assault’s success.
“Given the reorg was simply deeper than 600 blocks (Bittrex’s affirmation requirement for VTC), it’s potential that Bittrex was the unique goal, however the double-spend portion assault was aborted on account of Bittrex disabling their pockets earlier than the fork might be launched,” he added.
VTC/USD has fallen round 7% to $0.23 prior to now 24 hours, however the transfer is broadly insignificant throughout the context of 2019 highs of $0.61 seen in June.
As well-known pundit Andreas Antonopoulos beforehand noted, with Bitcoin, such an assault would price round $1 billion for a 10-minute offensive, one thing which in itself is all however inconceivable to attain.
