An unknown attacker that previously disrupted operations on the ethereum blockchain returned today, but so far to limited effect.
However, in what's perhaps a sign of how far developers have progressed in the last year, the attack was quickly spotted by the community.
Péter Szilágyi, a developer who works on the project's Go implementation, noted that a few ethereum developers, including ethereum creator Vitalik Buterin and geth developer Nick Johnson, contributed to "raising the alarm".
Within an hour, the popular implementation released a new version called 'Hat Trick', complete with a security fix that changed the structure of some types of data that were being utilized in the new attack.
As of press time, the attacker had not sent transactions from the account for an hour.
