Ethereum Classic news today is dominated by a social-engineering incident involving an unreviewed Core-Geth release that briefly prompted some mining operators to switch software before reversing course. Several mining operators reportedly installed the software temporarily. Crypto.news reported on September 18 that four 2Miners nodes were running CoreGeth v1.13.0 at 12:09 UTC before operators reverted to the maintained etclabscore/core-geth v1.12.23. KuCoin and Gate News separately reported on September 17 that a limited number of mining-pool nodes had switched before returning to the earlier client.
